Best Solar Software in Australia: Top 10 Tools for 2026

Anyone searching for the best solar software in Australia in 2026 is shopping in a market that has already been sold. More than four million rooftop systems are installed, roughly one in three freestanding homes carries panels, and the growth is no longer in finding a bare roof. It is in batteries bolted onto eight-year-old arrays, in inverter replacements, in service calls, in virtual power plant enrolments and in export limits that change hour by hour. That single fact should reorganise your software budget. A design tool is still the first purchase, but in Australia it is not the purchase that decides whether the business is profitable in year three. Our ranking puts SurgePV first at about A$1,990 (US$1,299) per user per year on the 5-User Team plan because it collapses four layers into one licence. It also does not do monitoring, control or dispatch, which in this market is a bigger hole than it would be anywhere else.

Direct answer. The best solar software in Australia for 2026 is SurgePV at roughly A$1,990 per user per year on the 5-User Team plan (A$9,950 for five seats), covering 3D design, 8,760-hour simulation, AS/NZS 5033 plan sets and white-label proposals in one licence. It does no monitoring, no VPP control and no crew dispatch, so most Australian installers pair it with a field service tool such as simPRO or Tradify, a monitoring platform such as Solar Analytics, and a compliance evidence tool for STC creation.

This page is the whole-stack view. If you only want the engineering tool, our solar design software Australia ranking scores ten platforms on AS/NZS 5033, multi-tilt layout and shading. Read this one if you are deciding what the full toolset should look like and what it should cost in Australian dollars.

Why the Australian Stack Argument Is Different

In a young solar market, software spending follows the sale. You buy a design tool, you buy a proposal tool, and everything after handover is a spreadsheet. Australia passed that phase around a decade ago. The Clean Energy Regulator’s own data shows small-scale installations accumulating past four million systems, which means the average Australian installer’s addressable work is now split roughly three ways: new installs on the remaining roofs, battery retrofits onto existing arrays, and service, repair and replacement on a fleet that is ageing into inverter end of life.

Each of those three has a different software centre of gravity. New installs need design, simulation and a proposal. Battery retrofits need something design tools handle badly, which is an accurate picture of an existing system you did not install: real consumption data, real generation history, existing string configuration and existing inverter capability under AS/NZS 4777.2. Service and repair need dispatch, job history, parts and photographic evidence, and none of that lives in a design platform.

The Six-Layer Australian Stack Score

We score every platform on how many of six layers it covers to a standard an Australian business can actually run on, then apply a weighted judgement on Australian depth: AS/NZS handling, SRES and STC mechanics, DNSP export rules and AUD pricing transparency. We call it the Six-Layer Australia Stack Score, and our design team applies it before adding anything to our own workflow.

1. Design and simulation to a standard that survives an AS/NZS 5033 review, including multi-tilt residential roofs and 8,760-hour shading.
2. Proposals and sales with STC value, state incentives, feed-in tariff by distributor and e-signature.
3. Compliance and certificate admin covering SRES evidence capture, installer and designer records and the audit pack.
4. CRM and pipeline covering leads, quotes outstanding, follow-up and commission.
5. Field operations covering scheduling, dispatch, job costing, work orders, photos and service history.
6. Monitoring and control covering production data, fault alerting, consumption analytics, battery orchestration and DNSP export response.

Layer coverage out of six: SurgePV 3, OpenSolar 3, Solar Analytics 1, Formbay 2, simPRO 2, SwitchDin 1, Fronius Solar.web 1, PVsyst 1, Tradify 2, Zoho CRM 1. Coverage does not decide the ranking on its own. SwitchDin covers one layer and is close to non-optional for anyone selling batteries into a flexible export zone, which makes it more valuable to that business than a platform covering three layers adequately.

The Top 10 Solar Software Platforms in Australia

Pricing is 2026, annualised, in Australian dollars, with USD list prices converted at roughly A$1.53 per US dollar. Several of these vendors negotiate above five seats, so get an AUD quote in writing.

1. SurgePV

What it does best. Turning one model into every document a job needs. Enter an Australian address, get an AI-built 3D roof from satellite imagery, place modules across the multiple tilts and azimuths that define Australian hip-roof housing stock, run the 8,760-hour module-level simulation for P50, P75 and P90 yield, apply the correct distributor feed-in tariff and STC value in the financial model, then generate the white-label proposal alongside the AS/NZS-labelled single-line diagram and bill of quantities. Clara AI takes plain-English design instructions, and DXF export hands cleanly to whoever stamps the structural work. For a retrofit quote it will happily model the added array or the battery against the existing system rather than forcing a fresh design.

Real pricing. About A$2,910 (US$1,899) per user per year on Individual, A$1,990 (US$1,299) per user per year on the 5-User Team plan, so A$9,950 for five seats. Enterprise is quoted. Free trial, no credit card.

Who it suits. Australian installers and EPC firms doing five or more jobs a month, teams working across several states and distributors, and anyone mixing residential retrofit with commercial where the financial model has to hold up.

Honest limitations. SurgePV does no monitoring whatsoever, which in the most monitoring-dependent solar market on earth is the single biggest gap in this ranking. It does no VPP orchestration and cannot receive or act on a dynamic operating envelope, so it has nothing to say about flexible exports once the system is live. It has no crew scheduling or job costing worth the name, so simPRO or Tradify sits beside it. It does not create STCs or assemble an SRES audit pack, so a compliance tool or your agent’s portal still handles that. Australian brand tenure is thin against OpenSolar, which has years of distributor relationships behind it. And on a large ground-mount project where a lender names PVsyst by report format, SurgePV complements it rather than replacing it.

2. OpenSolar

What it does best. Being free and being everywhere. OpenSolar is the default residential design and proposal tool across a large share of the Australian market, monetised through hardware and finance partners rather than a licence fee, with DNSP-aware workflows, STC handling in the pricing engine and an integrated proposal that Australian customers have seen before. For a small shop the argument is close to unanswerable: it costs nothing and it already speaks Australian.

Real pricing. A$0 for the core platform, which remains free. From 16 April 2026 OpenSolar begins charging for API Access on a per-project basis and for Connectors as a flat monthly fee, but it has not published the rates and they vary by region, so budget for them by asking OpenSolar directly rather than from any figure quoted elsewhere. The other real costs are imagery add-ons, premium 3D and the commercial terms attached to the partner ecosystem.

Who it suits. Residential installers up to moderate volume, and anyone whose priority is speed from doorstep to signed document rather than engineering depth.

Honest limitations. Shading and yield modelling are lighter than a dedicated hourly engine, so the proposal number and the engineered number can drift on a complex or heavily shaded roof. Commercial, ground-mount and battery-heavy work strain it. Documentation output stops well short of a plan set an electrical contractor wants. And free software is never free of a business model, so understand what the partner relationships are steering you toward. Our OpenSolar alternative comparison works through the trade-off in detail.

3. Solar Analytics

What it does best. Monitoring built for Australian conditions by an Australian company. Solar Analytics reads generation and household consumption at fine granularity, compares actual output against an expected model rather than against yesterday, and raises a fault when the gap is real. That distinction matters commercially: it is the difference between telling a customer their inverter is derating and telling them it was cloudy. For an installer carrying a fleet, the portal turns a support queue into a triaged list, and the consumption data is the strongest battery retrofit sales asset available, because it shows the household exactly how much evening load it is buying back from the grid.

Real pricing. A monitoring device is commonly A$350 to A$600 supplied and installed, with a subscription around A$100 to A$180 per site per year depending on term and plan. Installer fleet portals are bundled with volume.

Who it suits. Residential and small commercial installers with a fleet under maintenance, anyone selling battery retrofits, and businesses that offer a performance guarantee.

Honest limitations. It is a monitoring and analytics layer only. No design, no proposals, no scheduling, no certificate admin. It needs hardware at the site, which is an install cost and a truck roll on retrofit, and on newer systems some of what it does overlaps with what the inverter already reports for free. On a mixed fleet the value is high, on an all-Fronius fleet with a diligent installer it is more marginal.

4. Formbay

What it does best. Making STC creation survive an audit. The Small-scale Renewable Energy Scheme pays real money per system, and the Clean Energy Regulator inspects a sample of installations every year against the evidence submitted. Formbay-style compliance platforms exist to capture that evidence at the point of install: geotagged and timestamped photographs against a defined shot list, serial number capture, installer and designer identity, and a structured package that a certificate agent can act on. Done properly this is a software workflow on the roof, not a form in the office afterwards.

Real pricing. Typically charged per job, commonly in the A$10 to A$30 range depending on volume and whether certificate trading is bundled, sometimes absorbed by the STC agent you assign to.

Who it suits. Any Australian installer creating certificates at volume, which is nearly all of them, and particularly anyone who has already had a compliance finding.

Honest limitations. It solves one narrow problem. No design, no simulation, no CRM, no monitoring. Much of its value depends on which certificate agent you work with and what they already provide, so check for duplication before paying twice. Field usability on a hot roof with gloves on is the real test, and it varies.

5. simPRO

What it does best. Job management for a trades business that has outgrown a calendar. Built in Brisbane, simPRO handles quoting, scheduling, crew dispatch, timesheets, job costing against budget, purchase orders, asset and service history, and invoicing, with Australian GST and payroll realities built in rather than translated. For a solar business where service and maintenance revenue is growing faster than new installs, the recurring service module is the part that changes the P and L, because it makes a maintenance agreement something you can actually administer.

Real pricing. Not publicly listed. Simpro publishes no rate card; its pricing page routes to a quote, and the quote depends on user count, the add-on modules you take and a one-off setup fee. Any per-user figure you find in a software directory is a third-party estimate rather than a Simpro price, so treat this line as a quote you have to go and get.

Who it suits. Installers running two or more crews, anyone with a service and maintenance book, and businesses that need job costing because margin is leaking somewhere they cannot see.

Honest limitations. It knows nothing about photovoltaics. No string sizing, no shading, no STC logic, no export limits. Implementation is a genuine project rather than a signup, and half-configured simPRO is worse than a whiteboard. It is expensive for a two-person business, which is exactly why Tradify exists.

6. SwitchDin

What it does best. Control, which is the layer Australian solar has quietly made compulsory. Distributors are moving from fixed export limits to flexible exports, where the allowed export changes through the day according to a dynamic operating envelope sent by the network. SwitchDin, built in Newcastle, sits between the network signal and a mixed fleet of inverters and batteries, translating an envelope into device-level instructions and aggregating sites into a virtual power plant that can bid or respond. If you sell a customer a higher export limit on the basis of flexible export capability, something has to be able to receive that signal, and that something is a software product.

Real pricing. Licensed per site with a hardware gateway where the inverter cannot speak the protocol directly. Commonly a few dollars per site per month plus a gateway in the low hundreds of dollars, quoted by fleet size.

Who it suits. Installers selling batteries in flexible export zones, VPP aggregators, embedded network and community battery operators, and anyone whose fleet spans several inverter brands.

Honest limitations. One layer, and a technical one. No design, no proposals, no CRM, no job management. It assumes you have a fleet worth orchestrating, so it makes little sense below a few dozen sites. Commissioning per site takes real effort, and multi-brand support is only as good as each manufacturer’s API. Reposit Power and Evergen occupy adjacent ground and are worth quoting against.

7. Fronius Solar.web

What it does best. Free fleet visibility on the hardware a large share of Australian installers already fit. Solar.web gives per-site production, fault codes, alerting to the installer as well as the owner, and remote firmware and configuration on supported models, which occasionally turns a truck roll into a phone call. For an installer standardised on one inverter brand, the inverter portal is the cheapest monitoring layer that exists, because it is included.

Real pricing. Included with the hardware. Premium tiers add historical granularity and reporting at modest cost.

Who it suits. Residential installers standardised on a single inverter brand. The same argument holds for SolarEdge, Sungrow, GoodWe and Enphase portals in their respective fleets.

Honest limitations. Hardware locked, and Australian fleets are rarely single-brand for long. Three brands means three portals, no consolidated view and no consistent alert logic, which is the exact moment a hardware-agnostic platform starts to pay. Consumption data requires additional metering. No design, no proposals, no work orders, no certificate admin.

8. PVsyst

What it does best. Bankability. When a financier, insurer or independent engineer wants a second opinion on a multi-megawatt Australian project, the PVsyst loss diagram is the artefact they ask for by name. Its near-shading and loss modelling are documented well enough to defend line by line in a technical review, which is what a due diligence process actually requires.

Real pricing. PVsyst bills in Swiss francs, not Australian dollars. Professional is CHF 700 per user per year on an annual subscription, roughly A$1,340 at about A$1.91 per franc, with group discounts of 5 to 20 percent by quantity. Five seats is about CHF 3,500, so PVsyst is materially cheaper than SurgePV’s A$9,950 for five. It is one licence for simulation only, but on price alone it wins that comparison and we are not going to pretend otherwise.

Who it suits. Consultants, independent engineers, technical due diligence teams and developers producing yield reports for debt or equity on commercial and utility-scale work.

Honest limitations. Desktop only, steep learning curve, no proposal layer, no CRM, no permitting output, no Australian standards labelling and nothing whatsoever for a residential business. Reading the output correctly is a skill in itself, covered by our sister engineering team in how to read a PVsyst loss diagram. Our PVsyst alternative guide covers when you do not need it.

9. Tradify

What it does best. Being the job management tool a small Australian solar business will actually finish setting up. Built for trades across Australia and New Zealand, Tradify covers quotes, scheduling, job tracking, timesheets, invoicing and Xero or MYOB sync, and it can be running properly in a week rather than a quarter. For a two or three person shop, the honest comparison is not Tradify against simPRO, it is Tradify against the group chat and the shared calendar that are currently losing you a job a month.

Real pricing. Tradify publishes Australian prices in Australian dollars excluding GST: Lite A$48, Pro A$52 and Plus A$62 per user per month, with a Custom tier by quote. That is about A$2,880 to A$3,720 a year for five users.

Who it suits. Owner-operators and small crews, and service-heavy businesses that need job history more than they need job costing.

Honest limitations. Shallower than simPRO on job costing, purchasing, inventory and recurring maintenance contracts, which is precisely what you outgrow. Nothing solar-specific at all. No asset register deep enough to run a large service book.

10. Zoho CRM

What it does best. Cheap, configurable pipeline management with a serious automation engine underneath. For an Australian solar business whose problem is that quotes go quiet and nobody follows up, a general CRM configured around a solar pipeline, including the distributor approval wait and the install scheduling gap, usually beats a solar-specific tool at a fraction of the price. The wider Zoho suite covers desk, books and forms if you want one vendor.

Real pricing. Zoho publishes per-user list prices on its own pricing page and prices them per country, in Australian dollars among others. There is a free edition for up to three users, then Standard, Professional, Enterprise and Ultimate, each per user per month with a discount for annual billing. Take the current Australian figure from Zoho rather than from a range on a comparison page.

Who it suits. Sales-led installers, businesses with a long lead-to-install cycle, and anyone whose follow-up is currently a memory exercise.

Honest limitations. Generic. No solar proposal engine, no design, no STC logic, no production data, and it will do nothing useful until somebody spends real time configuring it. If canvassing and commission are your motion, a solar-native sales tool may fit better.

All 10 Compared: Layer, AUD Price and Best Fit

The layer column matters more than the price column, because most of these tools are not substitutes for one another.

#	Platform	Annual cost (AUD, 5 users)	Layers covered	Key capability	Best for
1	SurgePV	A$9,950	Design, simulation, proposals, plan sets	One model from address to proposal to SLD	Multi-state installers and EPCs
2	OpenSolar	A$0 core; API and Connector rates not published	Design, proposals, light CRM	Free and already familiar to AU customers	Residential shops at moderate volume
3	Solar Analytics	~A$100 to A$180 per site	Monitoring	Expected-versus-actual fault detection	Fleets under maintenance, battery sellers
4	Formbay	~A$10 to A$30 per job	Compliance, certificate admin	Audit-proof SRES evidence capture	Anyone creating STCs at volume
5	Simpro	Not publicly listed, quote only	Field ops, job costing	Service contracts and margin visibility	2+ crews with a maintenance book
6	SwitchDin	Per site, plus gateway	Control and VPP	Dynamic operating envelope response	Battery and VPP operators
7	Fronius Solar.web	Included with hardware	Monitoring	Free single-brand fleet visibility	Single-brand residential fleets
8	PVsyst	CHF 700 per user per year (~A$1,340)	Simulation	Lender-recognised yield reports	Consultants and utility scale
9	Tradify	A$2,880 to A$3,720 (A$48 to A$62/user/mo ex GST)	Field ops, light CRM	Fast to implement job management	Owner-operators and small crews
10	Zoho CRM	Published per user per month, priced per country by Zoho	CRM	Configurable pipeline automation	Sales-led installers

Verdict. Buy for the layer that is losing you money this quarter, not for the longest feature list. If your proposals and drawings are slow, SurgePV. If you are already fine on design and drowning in service calls, simPRO or Tradify. If customers keep telling you the system is broken and you cannot prove otherwise, Solar Analytics. If you are selling batteries into a flexible export zone, SwitchDin is not optional.

What Australian Solar Software Must Encode

A platform written for another market fails an Australian job in predictable ways, and the failures spread across every layer of the stack.

AS/NZS 5033 governs PV array installation and safety, and AS/NZS 4777.2 governs inverter grid connection, including power quality response modes and the demand response modes that make export control possible at all. AS/NZS 5139 covers battery energy storage installation, which is now the standard your retrofit work answers to. A design tool that labels to NEC 690 conventions gives an Australian electrical contractor a drawing to redraw.

Accreditation moved. Installer and designer accreditation transferred from the Clean Energy Council to Solar Accreditation Australia in 2024. The Clean Energy Council still runs the approved products lists and the Approved Solar Retailer programme, so both bodies matter, but they matter for different things. Any software field, proposal template or compliance checklist still describing installer accreditation as a CEC credential is carrying a stale reference into a customer-facing document.

STC mechanics are financial modelling, not admin. Certificates are deemed for the years remaining until the Small-scale Renewable Energy Scheme ends in 2030, so the deeming period shortens every January and the certificate count on an identical system falls with it. Certificate price also floats. A proposal tool with a hardcoded STC value produces a discount your customer will not receive, and the Clean Energy Regulator is the authority on both the deeming schedule and the audit obligations that follow.

Export rules are per distributor, and increasingly per hour. Static limits vary by network, from zero export on constrained feeders through to 5 kW or 10 kW per phase. Flexible exports replace that with a dynamic operating envelope calculated by the distributor, which can be far more generous most of the time in exchange for the system being controllable when the network is stressed. South Australia moved first and other networks have followed. This is why control software belongs in an Australian stack: an uncontrollable system in a flexible export zone gets the conservative limit, and the yield you modelled does not arrive.

Battery retrofit changes the design input. Federal support for home batteries under the expanded small-scale scheme pushed retrofit volume up sharply, and retrofit design starts from measured household consumption rather than an assumed load profile. That is a monitoring input feeding a design tool, which is a data flow most stacks have never been asked to support. Sizing arithmetic is worth cross-checking outside your primary tool with this battery sizing guide. Our solar plus storage design software comparison covers the tools in depth.

Monitoring, Control and O&M: The Layers Australia Cannot Skip

In most markets monitoring is the layer nobody buys until something breaks. In Australia it is closer to a licence to operate, for three separate reasons.

The first is fleet age. A business that has been installing for a decade is carrying thousands of systems through inverter end of life. Failures arrive as a customer phone call describing a bill, which is a terrible fault report. With expected-versus-actual monitoring the same event arrives as a triaged alert naming the site, the likely fault and whether it is under warranty, and you dispatch once with the right part. Without it you send a technician to confirm that it was cloudy.

The second is battery retrofit selling. A retrofit quote built on assumed consumption is a guess, and a guess that sizes a battery too large is a customer who never gets the payback you promised. Twelve months of interval consumption data turns that conversation into arithmetic, and the monitoring platform that collected it becomes the reason you win the retrofit rather than the retailer who cold-called.

The third is control. Once a network issues dynamic operating envelopes, the system’s export behaviour is a live negotiation between the distributor and the site, and somebody has to be responsible for the site holding up its end. If you enrolled the customer in a virtual power plant, you have also taken on a dispatch obligation, and the aggregation platform is the only place that obligation can be met. AEMO publishes the market and minimum demand context that explains why networks are pushing this way at all.

Practical behaviour worth insisting on from any Australian monitoring or control platform:

1. Expected-versus-actual fault detection. Alerting against a modelled expectation with irradiance and weather context, not against a fixed threshold that fires on every cloudy afternoon.
2. Consumption as well as generation. Because retrofit sizing, tariff advice and the battery conversation all run on load data.
3. Multi-brand fleet view. One list of sites needing attention across every inverter brand you have ever fitted, because the mixed fleet is inevitable.
4. Dynamic export response. Documented support for your distributors’ flexible export implementations, tested rather than promised on a roadmap.
5. Job continuity. The alert becomes a scheduled visit with history attached in the same system your crews already use, which is where simPRO or Tradify earns its place beside the monitoring platform.

Our view on where this is heading is set out in why AI is the future of solar operations and maintenance, and the practical workflow is in how to monitor solar generation. The metric every argument eventually reduces to is defined in our performance ratio glossary entry.

The Stack an Australian Installer Should Actually Buy

Layer coverage is theory. Here is the prescription by business type, in Australian dollars, based on what our own team and our channel partners run. Every one of these is two or three paid licences. None is one, and none is six.

1. Owner-operator, up to 3 jobs a month. OpenSolar for design and proposals, plus Tradify for jobs and invoicing, plus whatever inverter portal comes with the hardware. One paid licence. Tradify publishes A$48 per user per month on Lite, A$52 on Pro and A$62 on Plus excluding GST, so a single seat is roughly A$576 to A$744 a year. Do not buy a CRM and do not buy simPRO. Your certificate agent’s portal probably covers the STC evidence, so check before paying for a compliance tool.
2. Residential installer, one or two distributors, 15 to 40 jobs a month. SurgePV or OpenSolar for design and proposals, plus simPRO or Tradify for scheduling and job costing, plus Solar Analytics on every system you install. Two to three paid licences. Five SurgePV seats are A$9,950 and five Tradify seats are A$2,880 to A$3,720 excluding GST, so about A$13,000 to A$14,000 a year plus per-site monitoring on that shape. Simpro does not publish prices, so if you go that way the job management line is a quote rather than a budget figure. This is the most common Australian shape, and Solar Analytics is the line item people cut first and regret, because it is also the retrofit pipeline.
3. Retrofit and service specialist. simPRO first, because the service book is the business, plus Solar Analytics for fleet triage and consumption data, plus SurgePV or OpenSolar for the design work that retrofits still need. Three licences. Simpro does not publish prices, so the job management line here has to come from a quote rather than from a published rate. Note the inversion: here the job management tool is the primary purchase and the design tool is the accessory.
4. Battery and VPP operator. SurgePV for design and proposals, plus SwitchDin or an equivalent orchestration platform for envelope response and aggregation, plus simPRO for the field work. Three licences plus per-site control fees. SwitchDin and Simpro both price by quote, so only the SurgePV line is a published number. Do not sell VPP enrolment before the control layer is commissioned and tested against your distributor.
5. Commercial and industrial EPC. SurgePV for design, proposals and plan sets, plus PVsyst when a financier or independent engineer names the report format, plus a hardware-agnostic monitoring platform if you carry performance guarantees, plus Zoho CRM or similar for a long sales cycle. Three to four licences plus per-site monitoring. Zoho publishes per-user list prices per country on its own pricing page, so take the CRM line from there rather than from a range.

The pattern is consistent. Design and proposals is the layer worth consolidating into one licence, because splitting it costs money and lets the customer-facing number drift from the engineered one. Monitoring, control and field operations are bought on need, and they are bought from vendors who understand Australian distributors and Australian trades rather than from whoever sold you the design tool.

Pros and Cons: Standardising on SurgePV in Australia

SurgePV wins this ranking on bundled layer coverage and cost of ownership per seat. It loses on monitoring, which it does not do at all, on control and VPP, which it does not do at all, on STC certificate creation, on crew scheduling, and on Australian brand tenure against OpenSolar. Those are real gaps, not marketing caveats, and in a retrofit-heavy market they are the gaps that most affect an Australian business. Any vendor claiming to cover all six layers is describing a roadmap.

How Heaven Green Energy Helps

Heaven Green Energy has delivered more than 10,000 solar installations with an in-house design and engineering team, so we evaluate software as an operator rather than a reviewer. Our test for the best solar software in Australia is straightforward: does the number that reaches the customer survive the engineer, the distributor, the inspector and five years of operation without changing. That test is why bundled design and proposal platforms rank above sales-first tools here, and why we treat monitoring, control, field operations and certificate admin as separate purchases rather than checkboxes on a feature grid.

• Solar EPC services for turnkey design, supply and installation with performance guarantees.
• Commercial solar for 10 to 100 kW systems with full financial modelling.
• Industrial solar for 100 kW and above with bankable yield reporting.
• Structural and civil engineering for wind load and racking verification on commercial roofs.

Neutral market context for a board paper or a finance submission comes from the International Energy Agency and IRENA country profiles.

Frequently Asked Questions

What is the best solar software in Australia in 2026?

SurgePV ranks first overall at about A$1,990 per user per year on the 5-User Team plan, covering 3D design, 8,760-hour simulation, AS/NZS plan sets and proposals in one licence. OpenSolar is the strongest free alternative and remains the most widely used residential tool in Australia. Neither does monitoring, VPP control, certificate creation or crew dispatch, so Solar Analytics, SwitchDin, Formbay, simPRO and Tradify each own a layer that no all-in-one platform replaces.

How many software licences does an Australian solar installer need?

Two or three for almost every business shape. A bundled design and proposal platform is the core purchase, because splitting design and proposals across two vendors costs money and lets the customer-facing number drift from the engineered one. Add a job management tool such as simPRO or Tradify once you run more than one crew, and add monitoring as soon as your installed fleet is large enough that support calls cost real technician days. An owner-operator under three jobs a month can genuinely run on one paid licence plus free tools.

How much does an Australian solar software stack cost per year?

A five-person Australian installer commonly lands between A$13,000 and A$14,000 a year on a SurgePV plus Tradify plus monitoring stack, and more if the job management layer is Simpro, which publishes no prices. Bundled design and proposal platforms run A$0 to A$10,000 for five seats. Tradify publishes A$48 to A$62 per user per month excluding GST, so five seats are A$2,880 to A$3,720; Simpro publishes no prices and quotes on user count, modules and a one-off setup fee. Zoho publishes per-user CRM list prices per country on its own pricing page. Monitoring is roughly A$100 to A$180 per site per year. STC compliance tooling is charged per job, commonly A$10 to A$30.

Does solar software need to handle STC and SRES rules?

Yes, in two separate places. The proposal and pricing layer needs the current deeming period and a live certificate price, because deeming shortens every January until the scheme ends in 2030 and a hardcoded value produces a discount your customer will not receive. The compliance layer needs to capture audit-grade installation evidence, because the Clean Energy Regulator inspects a sample of installations each year and a failed audit can claw back certificate value already passed to the customer.

What is a dynamic operating envelope and does my software need to support it?

A dynamic operating envelope is an export limit that your distributor recalculates through the day according to network conditions, replacing a fixed limit with one that is usually more generous. Supporting it requires a control layer that can receive the signal and act on the inverter or battery, which is what platforms such as SwitchDin do. If you sell a customer a flexible export arrangement without a commissioned control layer, they will be placed on the conservative static limit and the yield in your proposal will not arrive.

Which software is best for solar battery retrofits in Australia?

A retrofit needs three things that a new-install stack often lacks. Measured household consumption over at least several months, which comes from a monitoring platform such as Solar Analytics or an interval data request. A design tool that will model a battery against an existing array and existing inverter rather than starting from scratch, which SurgePV handles. And a control platform if the customer is joining a virtual power plant. The installation itself answers to AS/NZS 5139 rather than the array standard alone.

Do Australian solar installers need a solar-specific CRM?

Usually not. A general CRM such as Zoho, configured around an Australian solar pipeline with stages for distributor approval and install scheduling, costs a fraction of a solar-specific tool and integrates with the accounting package you already run. Solar-native CRMs earn their premium if canvassing routes and commission structures are central to how you sell. For most Australian installers the bigger operational gain comes from job management rather than CRM, because scheduling and service history are where margin actually leaks.

Does any single platform cover the whole Australian solar stack?

No, and any vendor saying otherwise is describing a roadmap. Design platforms including SurgePV and OpenSolar stop at handover. Monitoring platforms know nothing about design. Control platforms know nothing about sales. Job management tools know nothing about photovoltaics. Certificate compliance tools do one narrow thing well. The realistic target is two or three licences chosen by which layer is costing you money this quarter, with design and proposals consolidated into one.
