The best solar proposal software in Malaysia is not the one that produces the glossiest cover page. It is the one that cannot quietly print the wrong savings number. Malaysia gives a proposal four different ways to be wrong before the engineering is even questioned: quote a factory on NEM NOVA using the NEM Rakyat one to one offset and you have overstated the export value, model a SELCO site as if it exports and you have invented revenue that the export limiter will never allow, leave GITA out of a C&I cash flow and you have understated the deal to the only person who signs it, and apply a single flat tariff when the customer sits in a different TNB category with an ICPT surcharge running against it and every ringgit downstream is built on sand. The platform that carries those four layers inside the document rather than beside it is SurgePV at roughly MYR 5,720 (US$1,299) per user per year on the 5-User Team plan. Ten platforms are ranked below in ringgit, with honest limitations on every one, ours included.
Direct answer. The best solar proposal software in Malaysia for 2026 is SurgePV, at about MYR 5,720 per user per year on the 5-User Team plan (roughly MYR 28,600 for five seats). It prices NEM Rakyat, NEM NOVA, NEM GoMEn and SELCO as four separate settlement mechanisms, carries TNB tariff categories with an ICPT line, models GITA in the after-tax cash flow, and exports a ringgit proposal backed by an 8,760-hour shading simulation. OpenSolar is the cheapest workable answer for a solo residential installer.
This ranking is written for Malaysian solar sales teams, EPC business development staff, registered electrical contractors quoting under Suruhanjaya Tenaga rules, and anyone selling C&I self-consumption across the Klang Valley, Penang, Johor and the Iskandar corridor, plus teams working Sabah and Sarawak where the rulebook changes. The engineering companion to this page is our best solar design software in Malaysia ranking, which covers monsoon diffuse fraction, MS IEC 62305 lightning protection and simulation depth. This page is about the document that closes the deal.
Four Settlement Mechanisms, Four Different Savings Numbers
The single most expensive assumption in Malaysian solar sales is that NEM 3.0 is one scheme. It is four pathways with four different economics, and the proposal is where that difference becomes money.
NEM Rakyat. Residential consumers offset exported units against imported units on a one to one basis, which makes an exported kilowatt hour worth the retail tariff. This is the friendliest case, and it is also the one every imported proposal template accidentally assumes. If your software has a single net metering toggle, this is almost certainly what it is doing.
NEM NOVA. The Net Offset Virtual Aggregation mechanism serves commercial and industrial consumers, and it credits exports at a displaced cost rate that sits materially below the retail tariff. It also allows offsetting across multiple accounts held by the same entity, which is a real commercial lever for a group with several premises and a genuinely useful thing to show in a proposal. Price NOVA exports at the retail rate and every export-heavy factory quote you send is inflated.
NEM GoMEn. Government ministries and agencies sit under their own arrangement, and the buyer behaves differently too. A GoMEn submission is a procurement document read by a technical committee, not a savings pitch read by a homeowner, and it needs equipment schedules, compliance references and a defensible yield basis rather than a lifestyle graphic.
SELCO. The self-consumption pathway has no export credit at all. The inverter runs with export limiting, and the system size is set by the daytime load curve rather than by roof area. A SELCO proposal that shows any export revenue line is describing a system that cannot legally exist. It also changes what the customer should buy: on SELCO, matching generation to the shift pattern is worth more than filling the roof.
Quota positions across these programmes have moved more than once since 2024, so confirm the live status with SEDA Malaysia and TNB before a number leaves your office. The net metering glossary entry covers the underlying mechanism if your team is new to it.
| Pathway | Who it serves | Export value | What the proposal must show |
|---|---|---|---|
| NEM Rakyat | Residential | One to one offset at retail tariff | Monthly bill offset, simple payback |
| NEM NOVA | Commercial and industrial | Displaced cost rate, below retail | Split of self-consumed and exported units, multi-account aggregation |
| NEM GoMEn | Government ministries and agencies | Programme-specific | Compliance schedule, equipment list, defensible yield basis |
| SELCO | Any consumer, self-consumption only | None, export limited | Load curve matching, zero export line, sizing rationale |
Read that table as four separate financial models rather than four labels on one model. On a 300 kWp Shah Alam factory roof, the gap between a NOVA-correct proposal and a Rakyat-assumed one runs to tens of thousands of ringgit across the term, and the customer’s own bill eventually exposes it.
📘 Regulation note
Grid-connected PV installation work in Malaysia falls under the Electricity Supply Act 1990 and the Electricity Regulations 1994, administered by Suruhanjaya Tenaga. The work must be carried out by a registered electrical contractor and supervised by a competent person of the appropriate grade. A proposal that promises a commissioning date without naming the contractor registration and the competent person grade is promising something the buyer cannot verify.

A savings figure is a tariff figure wearing a different hat. Get the tariff wrong and nothing downstream survives.
Tenaga Nasional Berhad bills different customer classes under different tariff structures, and the displaced value of a solar kilowatt hour depends on which one your customer sits in. A domestic consumer sits on a rising block structure where the marginal unit displaced is the most expensive one, which is why solar looks better for a high-consumption bungalow than for a small terrace house. A commercial or industrial consumer sits under a category with an energy charge plus a maximum demand charge, and on medium voltage tariffs there are peak and off-peak periods. Solar displaces peak-period energy well and touches maximum demand only partially, because the demand peak may occur after sunset or during a cloud passage. A proposal that credits solar with the full maximum demand reduction is overstating the case, and any competent facilities manager will say so.
Then there is the Imbalance Cost Pass-Through mechanism. ICPT is the surcharge or rebate applied periodically to reflect fuel and generation cost movements, and it is revised on a rolling basis. Commercial and industrial consumers have carried significant ICPT surcharges in recent cycles. That surcharge raises the effective cost of a displaced unit, which improves the solar case, and it also means the “current tariff” in your proposal is a moving target. Quoting a flat sen per kWh number with no ICPT line and no stated review basis is how a proposal ages badly between the pitch and the signature.
Yield in Malaysia is modest by Gulf standards, roughly 1,300 to 1,550 kWh per kWp depending on site, orientation and soiling, which means the Malaysian sale is won on tariff and tax rather than on sunshine. That is a useful thing to internalise before you choose a tool: the platform that models money carefully beats the platform that models light beautifully.
GITA and GITE Belong in the Cash Flow, Not the Footnote
For a Malaysian C&I buyer, the tax treatment is not a bonus paragraph. It is the number the finance director actually evaluates.
The Green Investment Tax Allowance, administered through MIDA with the qualifying asset list maintained by MGTC, lets a company claim an allowance on qualifying capital expenditure for green assets, set against a defined proportion of statutory income, with unutilised allowance carried forward. The Green Income Tax Exemption applies the same principle to qualifying green service providers, which matters if your customer is itself selling a green service, and it matters to you if you are one. Rates, qualifying lists and application windows have been revised at successive budgets, so treat the specific percentages as something to confirm against current MIDA guidance rather than something to hard-code into a template.
The proposal consequence is direct. On a self-consumption array for a Johor manufacturer, the after-tax payback with GITA claimed can be more than a year shorter than the simple payback. If your document shows only the simple number, you are competing against your own understatement. If it shows an after-tax number without stating the statutory income assumption, the finance director discounts the whole document. The correct output is a cash flow with the allowance treatment visible, the assumption stated, and the pre-tax number shown alongside so nobody accuses you of hiding behind the tax.
💡 Fast tip
During any vendor trial, ask for one real C&I case: NOVA export rate, SELCO export limiting on a second scenario, GITA claimed, ICPT stated. If the tool needs a spreadsheet to produce it, that spreadsheet is your permanent workflow.
The 5-Point Malaysia Proposal Bench
This is the frame used to rank every platform below, and you can run it yourself inside a free trial. Each axis scores 1 to 10, for a maximum of 50.
- Settlement accuracy. NEM Rakyat, NOVA, GoMEn and SELCO priced as four distinct mechanisms, with export limiting as a first-class scenario rather than a manual override.
- Tariff realism. TNB customer categories, block and peak structures, maximum demand handling, an explicit ICPT line and a stated review basis.
- Tax and financing. GITA and GITE treatment inside the cash flow, corporate tax position, financing and lease structures, and a multi-year statement a Malaysian CFO can audit.
- Document craft and compliance. White-label branding, e-signature, a technical annex referencing MS IEC standards, contractor registration and competent person fields, plus a procurement-grade format for GoMEn and large private tenders.
- Cost per finished proposal in MYR. Annual licence plus every required add-on divided by realistic monthly volume.
Axis 3 is where Malaysia separates from most markets covered in this series. In the UK the financing conversation is about a loan product. Here it is about a tax allowance, and the tool that cannot carry it loses C&I deals to the one that can.
Top 10 Solar Proposal Software Platforms in Malaysia Compared
Pricing is 2026, annualised, converted at approximately MYR 4.40 per United States dollar. Treat it as a planning figure rather than a quotation, and remember that every dollar-priced subscription here carries ringgit exchange risk.
| # | Platform | Indicative MYR price | Key capability | Best for |
|---|---|---|---|---|
| 1 | SurgePV | MYR 5,720/user/yr (5-user team) | NEM 3.0 settlement split, GITA cash flow, ICPT-aware tariffs, 8,760-hr shading behind the number | Contractors and EPCs sending 5+ proposals a month |
| 2 | Aurora Solar | USD $135/user/mo Basic, $220 Premium, billed annually (~MYR 7,128 to MYR 11,616/yr) | Most polished customer-facing residential document | Groups with an existing Aurora standard |
| 3 | OpenSolar | Free core platform; API Access and Connectors chargeable from 16 Apr 2026, rates not published | Free residential quoting with e-signature | Solo installers and new entrants |
| 4 | ARKA 360 | India list only: ₹46,000 to ₹1,00,000/yr plus 18% GST; no Malaysian price published | Fast address to 3D proposal with strong visuals | Small and mid-size Malaysian installers |
| 5 | The Solar Labs | Sits under Arka360; no separate price published | High residential throughput and quick turnaround | Volume residential teams |
| 6 | Solargraf | USD $2,799/yr Starter (2 users, 240 projects) to $12,999 Enterprise (~MYR 12,316 to MYR 57,196) | Quick permit-style quoting with e-signature | Residential-led teams on SolarEdge hardware |
| 7 | Pylon | Per project: USD $4.00 Standard, $10.00 Pro (~MYR 17.60 to MYR 44) | Quoting joined to hardware procurement | Installers reconciling quotes to distributor stock |
| 8 | QuickEstimate | ~MYR 1,800/user/yr | Solar quoting plus follow-up in one CRM | Sales-led firms buying design elsewhere |
| 9 | Enact | USD $279/mo for 2 users on annual (~MYR 14,731/yr for the pair) | Financing and lifetime savings storytelling | Sellers leading with monthly payment |
| 10 | Zoho CRM plus Zoho Sign | US$24/user/mo billed annually, US$288/yr (~MYR 1,270) | Generic quote, template and e-signature stack | SMEs with a strong admin and outsourced design |
Two readings before the detail. First, only the top entry treats NEM 3.0 as four mechanisms, which is why every other option on this list leaves a spreadsheet between your engineer and your customer. Second, these are not all the same unit: Aurora and QuickEstimate sell seats, Solargraf and Enact sell plans with project and user caps, Pylon bills per project and OpenSolar’s core platform is free. Compare on cost per finished proposal at your own volume rather than on the headline, and for a two-person Ipoh residential outfit the honest recommendation is the free one.
1. SurgePV
What it does best. SurgePV treats Malaysian settlement as structure rather than as a currency setting. NEM Rakyat one to one offsetting, NOVA displaced cost export, GoMEn and SELCO with export limiting are modelled as separate cases, so the savings number changes when the pathway changes rather than staying stubbornly the same. Tariff inputs carry TNB category structure with block and peak handling and an explicit ICPT line, so the displaced unit value in the document is traceable to something on the customer’s actual bill. The financial model carries corporate tax position, which is what lets a GITA claim appear in the cash flow rather than in a sentence under the chart.
The document itself is produced from the same model that produced the yield, so the shading study, the single-line diagram and the savings table cannot drift apart between revisions. Behind every generation figure sits an 8,760-hour module-level simulation on equatorial hourly weather with tropical soiling and humidity losses, which matters because a Malaysian proposal is frequently challenged on the yield assumption by a consulting engineer rather than on the price. The proposal builder supports white-label output, e-signature and a technical annex, and the generation and financial tool exposes the assumptions instead of burying them.
Pricing. About MYR 5,720 (US$1,299) per user per year on the 5-User Team plan, so roughly MYR 28,600 for five seats. Individual seats run higher. Free trial, no credit card.
Who it suits. Registered electrical contractors and EPCs sending five or more proposals a month, C&I sales teams selling self-consumption into manufacturing, and firms quoting across both NEM and SELCO pathways.
Honest weaknesses. Five, stated plainly. There is no native TNB application pack, so the connection submission stays manual and the proposal’s promised timeline rests on your own scheduling rather than on anything the software tracks. There is no Sarawak Energy variant, so teams quoting Kuching maintain the divergence themselves. GITA modelling is a tax treatment inside a cash flow rather than a compliance engine, so it does not check whether the specific asset appears on the current MGTC qualifying list, and that check is still a human job. It is not a CRM, so lead routing, WhatsApp follow-up and pipeline reporting need a second tool. And brand recognition in Malaysia is low because the product launched in 2025, which is a real friction when a Japanese or Singaporean parent company reviews the yield basis. We use SurgePV on our own solar EPC work, so weigh this ranking accordingly and run the bench yourself.
2. Aurora Solar
What it does best. Aurora produces the most polished customer-facing residential document in the category, refined against very large US volume, with mature templates and strong storage narrative. If your proposal competes against a local contractor’s Word file, Aurora wins that comparison on sight.
Pricing. Aurora publishes US dollar prices: Basic US$135 per user per month billed annually and Premium US$220, so US$1,620 and US$2,640 a year, roughly MYR 7,128 and MYR 11,616 at MYR 4.40 per dollar. Plan sets are a separately priced service rather than a plan inclusion, and LIDAR modelling, bankable shade reports and battery modelling sit on Premium. Stated plainly: Aurora Basic at US$1,620 a year undercuts a SurgePV Individual seat at US$1,899, and if a polished residential document is all you need, that is a real saving.
Who it suits. International groups extending into Malaysia with an Aurora standard, training and sales playbook already in place.
Honest limitations. The Malaysian layer is absent end to end: no NEM pathway split, no SELCO export limiting scenario, no TNB categories, no ICPT and no GITA treatment. Your team rebuilds all of that inside a template, which means it drifts the moment two salespeople edit it. LIDAR coverage across Malaysia is limited, so the headline roof capture degrades to manual tracing on many addresses. Our Aurora Solar alternative comparison covers the switch.
3. OpenSolar
What it does best. A genuinely free core design and proposal product funded by hardware referral margin, with usable residential templates, e-signature and a very low barrier for a new contractor. For a one-person business doing two or three residential jobs a month, it removes the software line item entirely.
Pricing. The core platform is free, for any number of users. OpenSolar has said that API Access, charged per project on creation, and Connectors, charged as a flat monthly fee, become chargeable from 16 April 2026, but it has not published those rates and they vary by geography. So a five-seat Malaysian team pays nothing today and cannot yet be quoted a 2026 add-on figure. Nothing else on this list is cheaper.
Who it suits. Solo installers and new entrants doing occasional residential work under NEM Rakyat.
Honest limitations. The economics steer you toward partner hardware, the commercial ceiling arrives fast, and there is no NEM pathway logic, no ICPT handling and no tax modelling. The moment you quote a NOVA factory or a SELCO warehouse, the free tier stops being free in staff hours. Our OpenSolar alternative page covers the migration cost honestly.
Want the engineering checked before the number goes out? Send us the roof plan, the load profile and the intended NEM pathway and our engineers will sanity-check the sizing and the export assumption before you quote. Talk to our engineering team or run a first pass with our solar calculator.
4. ARKA 360
What it does best. ARKA 360 gets from an address to a presentable 3D proposal quickly, at a price Malaysian small and mid-size installers can absorb. Its tariff inputs are flexible, which is more useful here than a rigid preset built for another country.
Pricing. ARKA 360 publishes rates for India only: Lite ₹46,000 a year, Basic ₹70,000 and Premium ₹1,00,000, all plus 18 percent GST, with a one-time onboarding fee of ₹10,000. There is no published Malaysian price list, so treat the India tiers as an indication and get a quote. SLD and SketchUp export are gated to Premium and no India plan includes e-signature.
Who it suits. Small and mid-size Malaysian installers who want credible visual output without an Aurora seat.
Honest limitations. No NEM pathway modelling, no SELCO export limiting scenario, no GITA treatment and no ICPT awareness. Commercial financial structures are thin, and the simulation depth behind the yield figure is lighter than the engineering-led platforms, which shows on a cluttered shophouse roof or a plant-heavy factory rooftop.
5. The Solar Labs
What it does best. Built for residential throughput, with fast layout and a workflow a junior salesperson can produce a competent document with on day one. Teams that imported an Indian sales motion into Malaysia often already know the interface.
Pricing. The Solar Labs brand sits under Arka360 and publishes no separate price list of its own, so the Arka360 tiers above are the closest published reference and a Malaysian quote has to come from the vendor.
Who it suits. Volume residential and light commercial teams that value speed over financial depth.
Honest limitations. The tariff and incentive content is built around Indian net metering and PM Surya Ghar logic rather than NEM 3.0, so the financial model needs rebuilding for Malaysia. No NOVA displaced cost rate, no GITA, no ICPT. Compare with our best solar proposal software in India ranking, where it fits its home market far better.
6. Solargraf
What it does best. Fast quoting with a clean customer-facing output and e-signature, with a workflow built around getting from lead to signed document in a single sitting. For a residential team standardised on SolarEdge hardware it slots in without friction.
Pricing. Solargraf prices by plan rather than by seat, in US dollars: Starter US$2,799 a year covering 240 projects and 2 users, rising to Enterprise US$12,999 for 1,500 projects. API access is US$4,000 a year on every plan except Enterprise. At MYR 4.40 per dollar that is roughly MYR 12,316 to MYR 57,196 a year.
Who it suits. Residential-led teams that want speed and a tidy document rather than engineering depth.
Honest limitations. No Malaysian regulatory or tariff content of any kind, and the commercial financial modelling is thin. Its strengths are shaped by North American residential sales, where the incentive logic and the utility structure look nothing like NEM 3.0 and TNB. On C&I work it runs out quickly.
7. Pylon
What it does best. Quoting joined to hardware procurement, so the bill of materials you quoted is the one you order at a price you have already seen. For installers who lose hours reconciling quotes against distributor stock, that is real weekly time recovered.
Pricing. Pylon is not a seat licence. It charges per project: US$4.00 on Standard and US$10.00 on Pro, with no monthly minimum, roughly MYR 17.60 and MYR 44. eSignature is US$0.80 a project, payments cost 2.50 percent a transaction, and the separate Solar CRM add-on starts at US$49 per user per month. For a low-volume Malaysian installer that model is dramatically cheaper than any per-seat product here, ours included.
Who it suits. Installers who want quoting and buying inside one system.
Honest limitations. Design depth is modest, the procurement advantage depends entirely on supplier coverage in Malaysia, and there is no NEM settlement logic or tax modelling. The stock catalogue does not know which components your competent person will accept against MS IEC references. See our Pylon alternative page.
8. QuickEstimate
What it does best. Built specifically for solar quoting and follow-up rather than adapted from a generic CRM, so the quote, the revision history, the follow-up sequence and the WhatsApp nudge sit in one place. For a Malaysian sales team losing deals to silence rather than to price, that ordering is correct.
Pricing. Around MYR 1,800 per user per year.
Who it suits. Sales-led firms that already have a design tool and need quoting discipline plus follow-up.
Honest limitations. It is not an engineering platform. No shading simulation, no NEM settlement engine, no GITA cash flow, so it pairs with a design tool rather than replacing one. Its proposal generator is strong on speed and weak on technical annexes.
9. Enact
What it does best. Enact frames the conversation around lifetime savings and financing, which is useful if your close depends on a monthly payment set against the current TNB bill.
Pricing. US$279 a month for 2 users on an annual commitment, or US$299 billed monthly, so about MYR 14,731 a year for the pair. Commercial projects are capped at 10 a month. Enact’s Asset Management and enterprise tiers are not publicly listed.
Who it suits. Sellers leading with financed residential and small commercial deals.
Honest limitations. Malaysian finance product coverage is thin against its US catalogue, the NEM pathway split is not modelled, GITA is absent, and the design engine is not a substitute for a proper shading study on a shaded urban roof. See the Enact alternative comparison.
10. Zoho CRM plus Zoho Sign
What it does best. It earns its place because a meaningful share of Malaysian solar SMEs genuinely run this way: a CRM, a quote template, a PDF and an e-signature tool at a price no solar-specific vendor matches. Zoho has real regional presence, and for a company doing six commercial deals a year with a capable administrator it works.
Pricing. Zoho publishes its rates in US dollars. Zoho CRM Standard is US$14 per user per month billed annually and Zoho Sign Standard is US$10, so US$24 per user per month, US$288 a year, before local tax. That is roughly MYR 1,270 per user per year, approximate, at MYR 4.40 to the dollar. Higher tiers cost more: Zoho CRM runs to US$52 per user per month on Ultimate and Zoho Sign to US$16 on Professional.
Who it suits. SMEs with low volume, a strong admin and design produced by an external consultant.
Honest limitations. Everything solar is manual: yield, tariff category, ICPT, NEM pathway, GITA, soiling, the technical annex, all of it. The document is only as accurate as the last person who edited the template, and template drift across a sales team is how two customers receive different savings assumptions for the same roof.
Proposal Mistakes That Cost Malaysian Installers Deals
-
1
Pricing NOVA exports at the retail tariff. Commercial exports are credited at a displaced cost rate below retail. Every export-heavy C&I proposal built on the retail number is overstated, and the first quarterly bill proves it.
-
2
Showing export revenue on a SELCO site. Self-consumption means export limiting at the inverter. Any exported kilowatt hour in that document is a system the customer cannot legally operate.
-
3
Quoting a flat tariff with no ICPT line. The Imbalance Cost Pass-Through surcharge moves, and it changes what a displaced unit is worth. State the category, the rate and the review basis or the proposal ages badly before signature.
-
4
Leaving GITA out of a C&I document. The allowance can shift after-tax payback by more than a year. Show only the simple payback and the finance director is evaluating a worse deal than the one you are offering.
-
5
Reusing a Peninsular proposal in Sarawak. Sarawak regulates its own electricity supply industry with Sarawak Energy as the utility and its own metering arrangements. The tariff, the scheme and the process references all change.
-
6
Omitting the contractor registration and competent person grade. Under Suruhanjaya Tenaga rules the installation needs both. A procurement committee reads their absence as a risk, not an oversight.
⚠️ Watch out
The most damaging Malaysian proposal error is not an optimistic yield. It is a savings figure built on the wrong NEM pathway, because the customer discovers it on a bill after commissioning, when the only remedy left is a refund conversation.
The wider set of delivery traps sits in our common mistakes EPC companies make in rooftop solar writeup, and the performance ratio entry explains why the losses in your annex compound rather than add.
Should a Malaysian Team Standardise on One Proposal Platform?
- ✓ You send more than 10 proposals a month
- ✓ You quote across NEM and SELCO pathways
- ✓ Your C&I deals turn on the after-tax number
- ✓ You bid GoMEn or large private tenders
- ✗ You close fewer than 5 residential jobs a month
- ✗ An external consultant produces all your designs
- ✗ You never quote above 100 kWp
- ✗ Your bottleneck is lead flow, not quoting
Verdict. For a Malaysian contractor with C&I ambitions, SurgePV is the right default because the settlement split, the tariff structure and the tax treatment are bundled and the engineering under the document is real. OpenSolar is the right answer for a solo residential installer. Aurora is right only if a group standard already forces it. Everything else here is correct for one shape of business and wrong for the others.

Frequently Asked Questions
What is the best solar proposal software in Malaysia in 2026?
SurgePV ranks first for Malaysian teams sending five or more proposals a month, at about MYR 5,720 per user per year on the 5-User Team plan, roughly MYR 28,600 for five seats. It prices NEM Rakyat, NEM NOVA, NEM GoMEn and SELCO as four separate settlement mechanisms, carries TNB tariff categories with an ICPT line, models GITA inside the after-tax cash flow, and backs every yield figure with an 8,760-hour shading simulation. For a solo residential installer, OpenSolar’s free core tier is the better value answer.
How does NEM 3.0 change a Malaysian solar proposal?
It changes the savings number four different ways. NEM Rakyat offsets residential exports one to one at the retail tariff. NEM NOVA credits commercial and industrial exports at a displaced cost rate below retail and allows aggregation across multiple accounts of the same entity. NEM GoMEn covers government ministries and agencies. SELCO has no export credit at all and runs with export limiting, so system size follows the daytime load curve. A proposal that models one generic net metering rate misprices at least two of the four cases.
Should GITA appear in a commercial solar proposal?
Yes, with the assumption stated. The Green Investment Tax Allowance, administered through MIDA with the qualifying asset list held by MGTC, lets a company claim an allowance on qualifying green capital expenditure against a defined proportion of statutory income, with unutilised allowance carried forward. For a manufacturer, that can shorten after-tax payback by more than a year against the simple payback. Show the pre-tax and after-tax numbers side by side and name the statutory income assumption, because a finance director discounts any figure they cannot reconstruct.
What is ICPT and why does it belong in the proposal?
The Imbalance Cost Pass-Through mechanism is a periodic surcharge or rebate applied to TNB bills to reflect movements in fuel and generation costs, revised on a rolling basis. It raises or lowers the effective cost of every unit your customer buys, which is exactly the number a solar kilowatt hour displaces. A proposal that quotes one flat sen per kWh rate with no ICPT line and no stated review date is describing a tariff that may no longer exist by signature, and commercial customers who watch their bills closely will notice.
Do Sarawak and Sabah need a different proposal?
Sarawak does, structurally. Suruhanjaya Tenaga’s jurisdiction covers Peninsular Malaysia along with Sabah and Labuan, while Sarawak regulates its own electricity supply industry under state law with Sarawak Energy as the utility and its own metering arrangements. Tariffs, scheme structure and process references all differ, so a Klang Valley template resubmitted in Kuching carries wrong numbers and wrong citations. Sabah sits under the federal regulator but is served by Sabah Electricity with different grid conditions and connection realities in parts of the state.
What does a Malaysian C&I proposal need that a residential one does not?
A load curve analysis showing the split between self-consumed and exported units, the correct NEM pathway named explicitly, the TNB tariff category with maximum demand treated honestly rather than assumed away, an ICPT line, a GITA-aware after-tax cash flow, and a technical annex referencing the MS IEC standards and the competent person grade. It should also state what solar does not do, notably that a demand peak occurring after sunset is not reduced by a PV array without storage.
How much does solar proposal software cost in Malaysia?
Most vendors bill in US dollars rather than in ringgit, and they do not all sell the same unit. OpenSolar’s core platform is free and its 2026 API and Connector rates are not published. Pylon charges per project, US$4.00 Standard or US$10.00 Pro, with no seat licence at all. SurgePV is US$1,299 per user per year on a five-seat team, about MYR 5,720.

Can free proposal software work for Malaysian solar sales?
For a narrow profile, yes. A solo installer doing occasional NEM Rakyat residential work can run inside OpenSolar’s free core with a competent person checking the electrical detail. It stops working the moment you quote a NOVA factory, a SELCO warehouse, a GoMEn tender or anything where the wrong settlement assumption becomes a refund conversation after commissioning. At that point the licence fee is smaller than one corrected C&I deal.
