Search for the best solar software in South Africa and you get a list of design tools, which answers a question most South African installers stopped asking around 2023. Designing the array is the easy part now. The hard parts are proving the system kept the lights on through Stage 4, keeping a fixed asset register that survives a Section 12B claim, and getting a technician from Centurion to a farm outside Bethlehem without burning a whole day of diesel and labour on a fault that turned out to be a flat BMS communication cable. Those are three different pieces of software and none of them is a design suite. This page ranks the ten platforms that matter across the full stack, prices them in rand, and then prescribes the actual two or three licence combination by installer type. The engineering core we rank first is SurgePV at roughly R24,000 (US$1,299) per user per year.
Direct answer. The best solar software stack in South Africa for 2026 is SurgePV for design and proposals at about R24,000 per user per year, paired with the free monitoring portal that ships with your chosen inverter brand (Sunsynk Connect, Victron VRM, SolarEdge or SOLARMAN Business), plus an accounting or job management layer such as Sage Business Cloud or Eworks Manager at R5,000 to R15,000 a year. Two or three licences, roughly R135,000 to R210,000 a year for a five-person team.
If you only want the single-category view, our best solar design software in South Africa ranking scores the engineering tools on SANS 10142-1 and hybrid sizing, and the best solar proposal software in South Africa guide covers Section 12B after-tax payback and PPA structures. This page is about how the layers fit together, who really chooses each one, and what the whole thing costs in rand.
Why Monitoring Sits at the Centre of a South African Stack
In most markets monitoring is the layer bought last, if at all. In South Africa it is the layer the customer bought the system for, which changes everything downstream.
A homeowner in Fourways who spends R220,000 on a hybrid system is not buying kilowatt-hours. They are buying the promise that the router, the geyser boost and the home office stay alive through a Stage 6 evening. That promise is either visible or it is disputed. When the battery hits zero at 19:40 on a Tuesday because the installer sized autonomy off an average day rather than a winter evening peak, the argument that follows is settled by data or by shouting. Monitoring is the only layer that produces data.
The commercial version is sharper. A cold storage operator in Epping who signed a rent-to-own agreement is paying a monthly instalment against an availability expectation. If the plant underperforms in June, somebody has to show whether the cause was irradiance, soiling, a tripped combiner or a grid event, and they have to show it before the next invoice goes out. That is a performance ratio calculation over a defined window, and it needs stored interval data, not a monthly total from the municipal bill.
The blunt consequence is that a South African installer who has excellent drawings and no fleet visibility is running the business backwards. The design tool is used once per project. The monitoring layer is used for twenty years, by the customer, in front of you.

Here is the part vendor-neutral roundups avoid saying. You do not choose your monitoring software. Your procurement department chose it eighteen months ago when it standardised on a brand, and every portal in this market is free precisely because it makes that decision sticky.
Sunsynk and Deye dominate the residential and small commercial hybrid installed base, and Sunsynk Connect or the SOLARMAN engine behind it is what those systems report into. Victron owns the off-grid, marine, agricultural and complex multi-source end, and VRM is genuinely the strongest free monitoring product in the country for that class of site. SolarEdge holds the premium grid-tied and module-level segment, where per-optimiser data settles shading arguments that no other portal can settle. Growatt and Solis sit at the value end with adequate portals and thinner fleet management. Huawei FusionSolar takes the larger commercial rooftops.
That leaves you with an honest strategic question rather than a shopping question: how much brand mixing can your operations team absorb. Three portals across forty sites means three logins, three alerting conventions, three data export formats and no single view of the fleet. Most South African installers who grow past about eighty sites either standardise hard on one or two brands, or they buy an independent aggregation layer and accept the cost.
⚠️ Watch out
Free vendor portals thin their interval history after a year or two. Export and archive your own data monthly, because a warranty or performance dispute in year four needs the granularity the portal no longer holds.
The Uptime-First Stack Test
This is the framework we use to judge whether a combination of tools covers a South African solar business, rather than whether any one product is good in isolation. Score your current stack 1 to 5 on each axis, for 30 total. Anything below 4 on an axis is where your next rand goes.
- Engineering credibility. Hourly simulation with local temperature derating, hybrid and battery sizing, SANS 10142-1 labelled drawings and a bill of quantities.
- Uptime evidence. Interval production and battery state of charge data, alerting, performance ratio, and a portfolio view across every site you carry.
- Commercial correctness. Section 12B after-tax modelling, VAT treatment, municipal and Eskom tariff structures, rent-to-own or PPA instalment maths.
- Revenue operations. Leads, quotes outstanding, follow-up, and the handover from sales to installation without retyping.
- Field execution. Job scheduling across long distances, technician routing, commissioning records, SSEG document packs and warranty evidence.
- Books and compliance. VAT201 filing, a fixed asset register that supports the 12B claim, supplier and stock records that survive an audit.
Layer coverage across the ten platforms we rank: SurgePV covers axes 1 and 3 strongly and nothing else. The inverter portals cover axis 2 and nothing else. Odoo touches 3, 4, 5 and 6 adequately and none of them brilliantly. Eworks Manager and Skynamo own axis 5. Sage owns axis 6. PVsyst owns a narrow slice of axis 1 that matters only when a lender names it.
Verdict. No product in this market scores above 12 of 30 on its own. That is the entire argument for a stack, and it is why a page ranking only design software cannot answer the question a business owner is actually asking.
The Top 10 Solar Software Platforms in South Africa
Pricing is 2026, annualised, converted at approximately R18.50 per US dollar where the vendor publishes in dollars. These tools sit in different layers, so the price column is not a like-for-like comparison and should not be read as one.
1. SurgePV
What it does best. The engineering and commercial core in one licence. A South African address becomes an AI-built 3D roof, then module placement, string sizing against local minimum and maximum design temperatures, an 8,760-hour module-level shading simulation, a hybrid battery and autonomy model, a SANS 10142-1 labelled single line diagram, a bill of quantities and a branded rand proposal. For this market the financial engine matters most: it separates self-consumed energy from exported energy, applies the Section 12B write-off to the after-tax payback on commercial work, and models a load shedding schedule as a demand event rather than an average.
Real pricing. About R24,000 (US$1,299) per user per year on the 5-User Team plan, so roughly R120,000 for five seats. Individual seats about R35,000 (US$1,899). Free trial, no credit card.
Who it suits. Installers and EPCs doing five or more designs a month, and anyone quoting commercial hybrid systems where autonomy and after-tax payback both have to be defended.
Honest limitations. SurgePV does no monitoring whatsoever, which in South Africa is the layer the customer cares about most, so it can never be your only licence here. It has no field service scheduling, no technician routing and no stock control, so a dispersed service business needs a second system. It does not file VAT201 and it is not a fixed asset register, so your 12B evidence lives elsewhere. The component library covers major inverter and module brands well but is thinner on smaller local racking and DB board suppliers. It does not automate any municipal or Eskom SSEG application, and no tool does. Where a lender names PVsyst by report format on a large project, SurgePV is a complement rather than a replacement.
2. Victron VRM
What it does best. Free, deep monitoring for complex and off-grid sites. VRM gives remote console access to the actual system, not just a dashboard: you can see battery state of charge, DC coupled solar, generator run hours, AC input availability and load, at high resolution, and you can change settings remotely. For a farm outside Kroonstad with a genset, a borehole pump and a 48 V bank, this is the difference between a diagnosis and a 400 km round trip.
Real pricing. Free with Victron hardware, including remote access and alerting. Data retention on the free tier is generous by market standards.
Who it suits. Off-grid, agricultural, lodge and multi-source installers, and anyone whose service calls are long-distance.
Honest limitations. Hardware locked to the Victron world. The interface rewards technical users and confuses homeowners. Portfolio-level commercial reporting is weaker than a purpose-built asset management platform, and there is no design, proposal, CRM or invoicing capability at all.
3. Sunsynk Connect
What it does best. Covering the brand that a very large share of South African hybrid systems actually use. Sunsynk Connect gives per-plant generation, battery state of charge, load profile and alarm history, with an installer view across your fleet and a homeowner app that absorbs a meaningful share of support calls by letting the customer see their own battery draining during Stage 4.
Real pricing. Free with Sunsynk inverters.
Who it suits. Residential and light commercial installers standardised on Sunsynk, which is most of the retrofit market.
Honest limitations. Alerting is basic and noisy, historical data granularity thins over time, and the fleet view struggles once you carry hundreds of sites. Cross-brand aggregation is not the product’s job. Treat it as evidence of uptime, not as an asset management platform.
4. SOLARMAN Business
What it does best. One portal across several value brands. Deye, Solis, Growatt and a number of rebadged units report into the SOLARMAN engine, so a mixed residential fleet can often be seen in one place. Business tiers add fleet alerting, technician assignment, customer sharing and report exports.
Real pricing. SOLARMAN publishes a free tier for basic plant monitoring and offers paid business and portfolio tiers, but IGEN Tech does not publish rates for them on its own site. Any rand figure you see for the paid tiers is a third-party estimate rather than a SOLARMAN price, so ask for a quote.
Who it suits. Installers carrying a mixed value-brand fleet who have hit the three-portal problem.
Honest limitations. Not truly brand-agnostic, since SolarEdge, Victron and Huawei sit outside it. Data model depth varies by inverter, so two plants can expose different fields. Support responsiveness is inconsistent, and it does nothing outside monitoring.
5. Odoo
What it does best. Being the general business system underneath a solar company. CRM and pipeline, quotations, purchase orders, stock across a warehouse and two bakkies, field service work orders, project stages, subscriptions for rent-to-own billing, and accounting. For a South African EPC that is invoicing monthly instalments on rent-to-own or PPA deals, the subscriptions module plus recurring invoicing is genuinely the cheapest way to run that book without spreadsheets.
Real pricing. Odoo publishes its list prices on its own pricing page and prices them per country. The shape is a free single-app tier with unlimited users, then Standard and Custom tiers charged per user per month with a discount for annual billing. Take the current South African figure from Odoo rather than from a range on a comparison page.
Who it suits. EPCs of eight people and up who carry stock, run crews and bill recurring revenue.
Honest limitations. Odoo knows nothing about photovoltaics. No design, no simulation, no string sizing, no generation data. Localisation for South African VAT and payroll usually needs a local partner and an implementation budget that can exceed the first year of licences. Implementing it in a five-person company with one van buries the company rather than helping it.
6. Sage Business Cloud Accounting
What it does best. The books, in a South African shape. VAT201 preparation, a proper fixed asset register, multi-currency for imported inverters and modules, and an accountant on every second street who already knows it. The fixed asset register is the quiet hero: a Section 12B claim is only as good as the asset records, invoices and commissioning dates behind it, and SARS is entitled to ask.
Real pricing. Commonly R450 to R1,100 per month depending on tier and user count, so roughly R5,400 to R13,200 a year.
Who it suits. Every registered South African installer above sole-trader scale. This is not optional software.
Honest limitations. It is accounting, nothing more. No project costing depth against a solar job, no stock intelligence worth the name at higher volumes, and no link to your design or monitoring layers without middleware. Xero is a reasonable alternative with better integrations and slightly weaker local convention.
7. Eworks Manager
What it does best. South African built job management for trades. Job cards, technician scheduling and live vehicle tracking, quotes and invoices, stock allocation to jobs, customer assets and service history, and mobile capture of photos and signatures on site. For a service business where travel is the largest controllable cost, the routing and job-card discipline pays for itself faster than any design licence.
Real pricing. Roughly R400 to R750 per user per month, so about R24,000 to R45,000 a year for five users, with local rand billing and local support.
Who it suits. Installers running two or more service vehicles across a province, and anyone doing maintenance and warranty work as a revenue line.
Honest limitations. Generic trades software. It does not understand strings, battery banks or performance ratio, so commissioning data lives as attachments rather than as structured records. Reporting is functional rather than analytical, and the mobile app is workmanlike.
8. Skynamo
What it does best. Field sales and account activity for teams that sell as they service. Built in Stellenbosch, Skynamo tracks reps in the field, logs visits against customers, and handles ordering from site. For a distributor-adjacent installer or a company with a rep covering the Free State, it produces the visibility that a CRM alone will not.
Real pricing. Commonly quoted around R700 to R1,300 per user per month, so roughly R42,000 to R78,000 a year for five field users.
Who it suits. Installers with an outbound field sales motion and dispersed customers, especially in agriculture and light industry.
Honest limitations. It is a field sales tool, not a solar tool and not a service dispatch tool. No design, no proposals with real yield behind them, no generation data. Priced at a level that only makes sense when field selling is a genuine revenue channel rather than an occasional activity.
9. SolarEdge Monitoring Portal
What it does best. Module-level truth. Per-optimiser production data means a shading dispute, a soiled panel or a single failed module is identified without anyone climbing onto a roof in Bloemfontein in July. The fleet view and automated alerts are stronger than most free portals, and the API is usable for teams that want their own reporting.
Real pricing. Included with SolarEdge hardware for the life of the system.
Who it suits. Installers standardised on SolarEdge in the premium residential and commercial grid-tied segment.
Honest limitations. Hardware locked, and SolarEdge’s share of the South African hybrid retrofit market is smaller than Sunsynk’s or Deye’s, so it rarely covers a whole fleet. Battery and backup behaviour reporting is less detailed than Victron’s on complex sites. No CRM, no field ops, no accounting.
10. PVsyst
What it does best. Bankability. When a development finance institution, an insurer or an independent engineer reviews a 15 MW wheeling project or a large C&I portfolio, the PVsyst loss diagram is the artefact they name. Its documentation and defensibility in a technical review are the product.
Real pricing. CHF 700 per user per year for the Professional licence, an annual subscription rather than a perpetual licence, roughly R16,050 at CHF 1 to R22.9. Education is CHF 420 and group discounts of 5 to 20 percent apply by quantity. Five seats are CHF 3,500, about R64,700, well under the R120,000 five SurgePV seats cost. For a firm whose only deliverable is a bankable yield report, PVsyst is the cheaper licence and pretending otherwise would not survive one click.
Who it suits. Independent engineers, technical advisers and utility-scale developers producing yield reports for debt or equity.
Honest limitations. Desktop only, steep learning curve, no proposal layer, no CRM, no drawings, no monitoring, no South African labelling conventions. It is a physics tool rather than a business tool, and buying it for residential hybrid work is a category error.
All 10 Compared: Layer, Rand Price and Best Fit
Read this table by layer rather than by rank. Position 2 beating position 10 does not mean Victron VRM replaces PVsyst. It means that for the job VRM does, in a South African fleet, it is the better buy.
| # | Platform | Layer | Price (ZAR per year) | Best for |
|---|---|---|---|---|
| 1 | SurgePV | Design, simulation, proposal | R24,000 per user (US$1,299) | The engineering and sales core of any serious stack |
| 2 | Victron VRM | Monitoring, remote control | Free with Victron hardware | Off-grid, agricultural and multi-source sites |
| 3 | Sunsynk Connect | Monitoring | Free with Sunsynk hardware | The residential hybrid retrofit majority |
| 4 | SOLARMAN Business | Monitoring, multi-brand | Free tier; paid tiers not publicly listed | Mixed Deye, Solis and Growatt fleets |
| 5 | Odoo | ERP, CRM, field service, billing | Free single-app tier, then published per user per month by country | EPCs carrying stock, crews and rent-to-own books |
| 6 | Sage Business Cloud | Accounting, VAT, asset register | R5,400 to R13,200 | Every registered installer, for 12B evidence |
| 7 | Eworks Manager | Field service and job cards | R24,000 to R45,000 for 5 users | Two or more service vehicles across a province |
| 8 | Skynamo | Field sales activity | R42,000 to R78,000 for 5 users | Outbound field selling into agri and industry |
| 9 | SolarEdge Portal | Module-level monitoring | Included with hardware | Premium grid-tied and shaded roofs |
| 10 | PVsyst | Bankable simulation | CHF 700 per user (about R16,050) | Financed C&I and utility-scale work |
Load Shedding, VAT and Section 12B: The Rules Your Stack Must Encode
Three South African facts decide whether an imported tool is usable here, and all three sit outside the design layer.
Load shedding is a demand-side event, not a supply-side one. A grid-tied inverter without backup capability stops producing when the grid drops, so a plant can look faulted for two hours a day in a Stage 4 week while being perfectly healthy. Any alerting rule that treats zero output as a fault will drown your technicians in false positives. Ask a monitoring vendor directly how they classify grid-absence periods in availability and performance ratio, because the answer changes your service costs. Eskom publishes the schedules, and correlating your fleet gaps against them is a five-minute discipline that saves whole days.
Section 12B is an accounting artefact before it is a sales argument. The allowance lets a business write off qualifying renewable plant against taxable income, which is why it belongs in the proposal. What is less discussed is that the claim rests on records: supplier invoices, the commissioning date, an asset register entry, and evidence the plant was brought into use. That is a job for your accounting layer, not your design tool. The authority is SARS, and treating this as paperwork you generate at year end rather than at commissioning is how claims get queried.
VAT and SSEG record-keeping run in parallel. VAT201 filing is routine, but a solar business carries a specific mix of imported capital equipment, zero-rated and standard-rated lines and progress payments, which is exactly the shape that goes wrong on a spreadsheet. Separately, SSEG registration with Eskom or your municipality is required even for systems that never export, and the registration pack (SANS 10142-1 Certificate of Compliance, NRS 097-2-1 compliant inverter evidence, the single line diagram, the professional sign-off where required) has to be retrievable years later when the property is sold or the municipality audits. NERSA sets the registration framework and municipalities apply their own variants on top.
📘 Regulation note
Keep the SSEG pack for every site in one system with the customer record, not in the installer's inbox. City of Cape Town, City of Johannesburg, eThekwini and Eskom Direct each ask for a slightly different document set, and reassembling it two years later without a job management system is a day of work per site.
Field Service When Your Sites Are 300 km Apart
South African service economics are dominated by distance, and this is where a monitoring layer and a field layer earn their keep together.
The arithmetic is unforgiving. A technician plus a bakkie costs real money per kilometre before you count the day. Sending two people 250 km to reset an inverter that a remote console could have reset is a straight loss, and doing it four times a month across a growing fleet costs more than every software licence in this article combined. Remote diagnosis is therefore not a convenience feature, it is the highest-return capability in the stack, which is a large part of why Victron VRM ranks where it does.
The second lever is trip consolidation. When you can see which of your Free State sites have open alarms, a Thursday run can close five jobs instead of one. That requires alarms to be visible in the same place as the job scheduling, which is the integration most South African installers never build. A weekly consolidated fleet review, exported from every portal you run into one sheet, then converted into a route, is a manual process that beats not doing it at all.
- Triage remotely first. Confirm from data whether the site has a fault, a grid-absence gap or a soiling trend before anyone is dispatched.
- Batch by geography, not by complaint order. The customer who shouted loudest is rarely the most efficient first stop.
- Carry the commissioning record. String test values, inverter firmware and settings from day one, available on the phone at the site.
- Close the loop into the asset record. What was replaced, under whose warranty, with a photo, against the customer, so the next visit starts informed.
- Bill or absorb explicitly. Warranty, goodwill or chargeable, decided at the job card rather than three weeks later.
Our view on where remote operations is heading is in why AI is the future of solar operations and maintenance, the practical measurement workflow is in how to monitor solar generation, and the intervention side is in our solar quarterly maintenance checklist. Definitions worth being precise about with customers are performance ratio and depth of discharge, since both appear in arguments about whether a battery underdelivered.

The Stack We Prescribe, by Installer Type
This is the practical output of the page. Four profiles, four different answers, with annual rand cost. Every one of them is two or three paid licences, not one and not six.
Profile A: residential hybrid installer, 2 to 6 people, retrofit backup work. Two paid licences. SurgePV on a 5-User Team plan at about R120,000 a year for design, autonomy sizing and the proposal, or a free design tool at the start if cash is tight. Monitoring free from Sunsynk Connect or SOLARMAN, whichever your standard inverter reports into. Sage Business Cloud at roughly R7,000 a year for the books and the asset register. Field work stays on a shared calendar and a group chat at this size, and that is defensible below about fifteen jobs a month. Total: roughly R127,000 to R135,000 a year.
Profile B: commercial and industrial EPC, 8 to 25 people. Three paid licences. SurgePV at R120,000 for five seats as the engineering and after-tax proposal core. Odoo at its published South African per-user rate for five users covering CRM, purchase orders, stock and field service work orders. Sage or Odoo accounting at R7,000 to R13,000 for VAT201 and the 12B asset register. Monitoring free from Huawei FusionSolar or SolarEdge according to your specified hardware, with a monthly export discipline on top. Add PVsyst at CHF 700 per user, about R16,050, only when a funder names it. Total: R165,000 to R210,000 a year.
Profile C: O&M and service contractor managing installed assets. A different stack entirely, and the one where buying a design suite is the classic category error. Monitoring is the primary tool and it is free, but you will run three portals because the fleet is mixed, so budget for the weekly consolidation discipline rather than for a design licence. Eworks Manager at roughly R30,000 for five users for job cards, scheduling and vehicle routing. Sage at R7,000. One design seat only if you also sell upgrades. Total: roughly R40,000 to R80,000 a year.
Profile D: rent-to-own or PPA operator billing monthly. Three licences with a different centre of gravity. Odoo at its published South African per-user rate for subscriptions, recurring invoicing, debit order runs and the customer contract record, because the business is a finance book with panels attached. An independent or aggregated monitoring layer, paid if necessary at R5,000 to R12,000, because availability is contractual here rather than reputational. SurgePV at R120,000 for the engineering and the after-tax model that decides whether a deal is worth writing. Total: R160,000 to R175,000 a year.
The pattern across all four is the same. Design and proposal is the layer worth consolidating into one licence, monitoring is taken free from your hardware choice and treated seriously anyway, and the third licence is decided by whether your money leaks through crews, through the pipeline or through the books.
Buy This Layer, Not That One
- ✓ You quote five or more hybrid systems a month
- ✓ Commercial clients question your autonomy claims
- ✓ Section 12B maths is done in a spreadsheet
- ✓ Your engineer redraws every SLD by hand
- ✗ Technicians drive to faults they could have reset remotely
- ✗ You cannot produce an SSEG pack for a two-year-old site
- ✗ Your 12B asset records live in a folder of PDFs
- ✗ Nobody can say how many quotes are open today
Five Stack Mistakes South African Companies Make
-
1
Treating monitoring as the customer's app. It is your evidence, your service triage and your defence in a battery dispute. Set it up as a fleet, not as forty individual plants.
-
2
Letting the portal dictate procurement forever. Free monitoring is free because switching brands is painful. Price that lock-in before you standardise on a supplier.
-
3
Selling Section 12B without building the record. The proposal claims the write-off, then nobody keeps the commissioning date and asset entry that support it.
-
4
Buying an ERP at five people. Odoo repays a twenty-person company with a warehouse and a rent-to-own book. It buries a small team with one bakkie.
-
5
Alerting on zero output. During load shedding that is normal behaviour, and a rule that treats it as a fault trains your team to ignore alarms entirely.
The delivery failures those buying errors produce are covered in our common mistakes EPC companies make in rooftop solar writeup.
How Heaven Green Energy and SurgePV Help South African Teams
Heaven Green Energy has delivered more than 10,000 solar installations with an in-house engineering group, and we build software for jobs we do ourselves rather than for a roadmap. That is why this page recommends free monitoring and a paid engineering core rather than recommending our own product for all six layers. Useful starting points:
- Solar EPC services for turnkey design, supply and installation with performance guarantees.
- Commercial solar for systems where after-tax payback decides the deal.
- Industrial solar for 100 kW and above with bankable yield reporting.
- Hybrid battery sizing guide from our sister engineering team, for the autonomy maths behind a load shedding proposal.
- Battery energy storage resource centre for storage engineering references.
Neutral market context for a board paper comes from the International Energy Agency and IRENA country profiles. If you are assembling the best solar software in South Africa for your own company, write down which of the six layers cost you money last month, and buy that one first.

Frequently Asked Questions
What is the best solar software in South Africa in 2026?
SurgePV ranks first as the engineering and proposal core at roughly R24,000 per user per year on the 5-User Team plan, covering design, hourly simulation, hybrid autonomy sizing, SANS 10142-1 drawings and rand proposals with Section 12B after-tax modelling. It does no monitoring, so every South African stack pairs it with the free portal from your inverter brand, usually Sunsynk Connect, Victron VRM, SOLARMAN Business or SolarEdge, plus an accounting or job management layer.
Do South African installers have to pay for solar monitoring software?
Almost never. Sunsynk Connect, Victron VRM, SolarEdge, Growatt and Huawei FusionSolar all bundle monitoring with the hardware for the life of the system, which is why your inverter procurement effectively chooses your monitoring layer. You pay only when a mixed fleet has grown past the point where three portals is worse than one subscription, at which stage an aggregation platform or a SOLARMAN Business tier at roughly R2,000 to R12,000 a year becomes the cheaper option.
How much does a South African solar software stack cost per year?
A five-person installer commonly lands between R135,000 and R210,000 a year. SurgePV is about R120,000 for five seats. Monitoring is usually free. Accounting through Sage Business Cloud runs R5,400 to R13,200. Field service through Eworks Manager runs R24,000 to R45,000 for five users, and Odoo publishes a per-user South African rate on its own pricing page. PVsyst adds CHF 700 per user, about R16,050, only when a funder names it in the document list.
How should solar software handle load shedding in monitoring alerts?
It has to separate grid-absence periods from faults. A grid-tied inverter without backup stops producing whenever the grid drops, so a healthy plant can show hours of zero output every day during Stage 4. Alerting rules that flag zero output as a fault generate false positives that train technicians to ignore alarms. Ask the vendor how grid-absence periods are treated in availability and performance ratio, and correlate fleet gaps against the published Eskom schedule.
What software keeps Section 12B records for a solar business?
The accounting layer, not the design tool. A Section 12B claim rests on supplier invoices, the commissioning date, an asset register entry and evidence the plant was brought into use, all of which live in Sage Business Cloud, Xero or an ERP such as Odoo. The proposal software calculates the benefit and the accounting software has to be able to prove it. Building the record at commissioning rather than at year end is what keeps a claim clean with SARS.
Which software handles SSEG registration paperwork?
None of them automates the application, because Eskom Direct, City of Cape Town, City of Johannesburg and eThekwini each ask for a slightly different pack. What software can do is store the pack against the customer record so it is retrievable years later: the SANS 10142-1 Certificate of Compliance, evidence of an NRS 097-2-1 compliant inverter, the single line diagram and any professional sign-off. A job management system such as Eworks Manager or an ERP such as Odoo is the right home for it.
Do South African solar installers need a solar-specific CRM?
Usually not. General systems fit better here because the pain is normally stock, cash and technician time rather than canvassing. Odoo covers CRM alongside purchase orders, stock and field service, which is the combination most growing EPCs need. Skynamo suits companies with a genuine outbound field sales motion into agriculture and industry. Buy a solar-specific pipeline tool only when lead volume rather than delivery capacity is your constraint.
What software do rent-to-own and PPA solar operators use for billing?
Recurring billing systems rather than solar tools. Odoo subscriptions with recurring invoicing and debit order runs is the common answer, because the operator is running a finance book with hardware attached, and each contract needs an instalment schedule, an escalation clause and a contract end date. Monitoring becomes contractual rather than reputational in these deals, since availability underpins the invoice, so an independent or aggregated monitoring layer is worth paying for.
Stop paying for four tools. Design it all in one.
