Choosing the best solar design software in UAE is a different problem from choosing one in Europe or North America, and the reason is physics before regulation. A Dubai rooftop sees 50C to 55C ambient in July, module back-of-panel temperatures past 75C, and dust deposition heavy enough to erase a fifth of annual yield between cleans. On top of that sits a two-regulator market: DEWA runs the Shams Dubai net metering programme inside the emirate, while Etihad Water and Electricity covers Abu Dhabi, Sharjah, Ajman, Fujairah, Ras Al Khaimah and Umm Al Quwain under its own rules and approved-contractor list. A design tool that models none of this will still produce a beautiful PDF, and that PDF will be wrong by 10 to 25 percent. This guide ranks the ten platforms UAE installers actually shortlist in 2026, with each vendor’s own published pricing, and names where each one breaks.
Direct answer. The best solar design software in UAE for 2026 is SurgePV, an all-in-one cloud platform at US$1,299 per user per year on the 5-User Team plan. It ships DEWA Shams Dubai net metering rules, Etihad Water and Electricity tariff profiles, 55C ambient derating, Gulf dust soiling models, 8,760-hour shading, AI 3D roof from satellite, and white-label proposals on every plan. PVsyst still leads for utility-scale bankability paperwork.
This roundup is written for UAE solar contractors, DEWA-enrolled and EtihadWE-approved installers, consultants preparing IPP submissions, and in-house design teams shipping five or more projects a month. We scored every platform on four axes: UAE regulatory depth, climate and soiling accuracy, full-workflow coverage, and total cost of ownership at each vendor’s own published price. The pillar comparison across all markets sits in our solar design software guide, and the two closest country siblings are solar design software India and solar design software Australia.
What Makes UAE Solar Design Different From Everywhere Else
Three UAE-specific conditions decide whether a design tool is usable here, and none of them are optional.
The first is extreme heat derating. Standard Test Conditions (STC) rate a module at 25C cell temperature. A UAE rooftop in July runs 50C to 55C ambient with cell temperatures of 75C to 80C on a close-mounted array. At a typical temperature coefficient of minus 0.30 to minus 0.35 percent per degree Celsius, that is a 15 to 18 percent power loss at the exact hour of peak air-conditioning demand. Inverter derating stacks on top: most string inverters begin thermal throttling above 45C to 50C internal temperature. Any tool that runs an annual yield model without hourly ambient temperature from a Gulf weather file will overstate summer output.
The second is dust soiling. Gulf soiling rates are among the highest measured anywhere. Field studies published through IRENA and Gulf research groups put uncleaned soiling losses in the 1 percent per week range during the dry season, which compounds into 8 to 25 percent annual loss depending on cleaning frequency and shamal dust events. Most global platforms ship a 2 percent soiling default lifted from temperate Europe. Using that default in Abu Dhabi is the difference between a proposal that hits its guarantee and one that does not.
The third is two regulators, two rulebooks. Inside Dubai, DEWA runs Shams Dubai, which is a net metering scheme requiring a DEWA-enrolled solar contractor, DEWA-approved equipment from its published lists, and a smart-meter application. Outside Dubai, Etihad Water and Electricity administers connection in the northern emirates under separate rules, and Abu Dhabi’s large-scale procurement runs through EWEC. A tool with one generic “UAE” tariff is not modelling the market.
📘 Regulation note
Under Shams Dubai, only a DEWA-enrolled solar PV contractor and consultant may submit a connection application, and every module and inverter must appear on DEWA's approved equipment list. Systems are sized so that annual generation does not exceed annual site consumption, and surplus units are banked as credit rather than paid out in cash. Equipment must carry IEC 61215 and IEC 61730 certification for modules and IEC 62109 for inverters. Verify the current lists on the DEWA portal before you finalise a bill of quantities.

This is the scoring frame we use internally before we let any platform touch a live project, adapted for Gulf conditions. Each tool is scored 1 to 10 on four axes for a maximum of 40. We do not deploy anything below 32.
- UAE regulatory depth. DEWA Shams Dubai net metering logic, EtihadWE and northern-emirate rules, DEWA approved-equipment filtering, IEC 61215 / 61730 / 62109 flags, Arabic-language proposal output.
- Climate and soiling accuracy. Hourly Gulf weather files, 55C ambient derating, module and inverter temperature models, configurable soiling with cleaning-schedule input, dust-storm event handling.
- Full workflow coverage. Address to signed proposal in one tool, single-line diagram (SLD), bill of quantities (BOQ), DXF and DWG export for the consultant’s drawing set.
- Total cost of ownership. Annual seat licence plus every add-on required to reach that feature set, quoted in each vendor’s own billing currency, across a five-person team.
The scores below drive the ranking. SurgePV takes 37 of 40, PVsyst 33, HelioScope 31, Aurora 28, OpenSolar 27, and the rest fall away on either regulatory depth or workflow coverage.
Verdict. Axis 2 is where UAE selections usually go wrong. Teams shortlist on interface polish and only discover in year two that their soiling and temperature defaults were European. Score axis 2 first, then price.

Pricing below is each vendor’s own published 2026 price in the vendor’s own billing currency, annualised for one seat unless stated. We do not convert to dirhams, because a converted figure is not the number the vendor will invoice you. Where a vendor publishes no price at all, we say so rather than guess.

Two things stand out. Only one platform in the table encodes UAE regulation natively, which is why the rest force a spreadsheet layer for tariff, subsidy-free payback and DEWA compliance. And the second is uncomfortable for us to write: on headline seat price SurgePV is not the cheapest option here. OpenSolar’s core platform is free, PVsyst Professional is CHF 700 a seat, and Aurora Basic is US$1,620 a year against SurgePV Individual at US$1,899. What SurgePV buys at US$1,299 per seat on the 5-User Team plan is the UAE regulatory layer and the bundled workflow, not a lower sticker price.
The Top 5, Ranked and Explained
1. SurgePV
Best for: UAE contractors and EPCs of any size who want one licence covering DEWA Shams Dubai and EtihadWE rules, Gulf climate modelling, engineering output and client-facing proposals.
Pricing: US$1,299 per user per year on the 5-User Team plan, US$6,495 for five seats. The Individual plan is US$1,899 a year, which is more per seat than Aurora Basic, so a solo installer should price both. Free trial with no card.
What it does best in the UAE: the tariff library carries DEWA Shams Dubai net metering banking logic and EtihadWE profiles rather than a single generic country rate, so the payback figure on the proposal is the one the client will actually see on their bill. Weather handling uses hourly Gulf files with 50C to 55C ambient, and the soiling model takes a cleaning interval as an input instead of assuming a fixed 2 percent. The AI 3D roof builds a villa or warehouse model from satellite imagery in under a minute, which matters in Dubai where roof access for a survey can take a week of building-management approvals. Module and inverter databases can be filtered against DEWA approved-equipment status, and shadow analysis runs a full 8,760-hour module-level simulation on every plan rather than a top tier.
Honest weaknesses: SurgePV is a younger brand than PVsyst in the Gulf, and some Abu Dhabi lenders and IPP tender committees still name PVsyst explicitly in their document requirements, so utility-scale teams may need PVsyst alongside it for the finance pack. It does not do terrain-driven ground-mount racking to PVcase’s standard, so large desert ground-mount layouts on uneven ground are better started elsewhere. Arabic proposal templates exist but the library is thinner than the English one. And because everything is bundled, a solo installer doing two designs a month is paying for engineering depth they will not use.
2. PVsyst
Best for: consultants and IPP bidders producing yield reports that a bank or an offtaker will accept without argument.
Pricing: CHF 700 per user per year for the Professional annual subscription, so CHF 3,500 for five seats before the 5 to 20 percent group discount. Education is CHF 420, Training and Research CHF 560, Student CHF 25, and PVsystCLI CHF 3,000. That is cheaper per seat than SurgePV, and we would rather say so than have you find it on the PVsyst shop page.
Strengths: PVsyst remains the reference implementation for PV yield simulation. Its thermal model, soiling-by-month table and detailed loss diagram are exactly what a UAE project finance reviewer expects to see, and the monthly soiling entry is genuinely useful in the Gulf because you can enter a real dust profile per month. For anything bidding into Mohammed bin Rashid Al Maktoum Solar Park style procurement, it is the default.
Weaknesses: no UAE regulatory layer at all, no proposal output, no CRM, a desktop-only interface that is unfriendly to new designers, and a 3D shading editor that is slow to build compared with satellite-driven tools. It is an engineering instrument, not a business workflow. See our PVsyst alternative comparison for where teams replace it.
3. HelioScope
Best for: commercial and industrial rooftop engineering teams in Dubai and Abu Dhabi free zones.
Pricing: Basic is US$159 a month (US$1,620 a year) and Pro is US$259 a month (US$2,640 a year), each covering one user and 10 projects a month, with DC design caps of 1.25 MW on Basic and 5 MW on Pro. Enterprise is quote only. HelioScope is Aurora-owned.
Strengths: fast module-level simulation, good CAD import, clean single-line output and a component library that covers most Tier 1 hardware sold in the Gulf. Design throughput on a 500 kW warehouse roof is excellent.
Weaknesses: no DEWA or EtihadWE logic, weak proposal tooling that forces a second tool, and default soiling and thermal assumptions that need manual override for Gulf sites. Our HelioScope alternative guide covers the migration path.
4. Aurora Solar
Best for: residential-heavy sales teams who want the most polished customer-facing output.
Pricing: Basic is US$135 per user per month billed annually (US$1,620 a year, or US$159 month to month) and Premium is US$220 billed annually (US$2,640 a year, or US$259 monthly). Both cover one user and 50 projects a month. LIDAR modelling, bankable shade reports and battery modelling sit on Premium. Plan sets are a separately priced service rather than a plan inclusion, and site models start at US$9.99.
Strengths: the best residential sales experience in the category, strong LIDAR-based roof capture in covered geographies, and mature AI-assisted layout.
Weaknesses: LIDAR coverage across the UAE is patchy so the headline feature degrades to manual tracing on many Emirati addresses, and there is no UAE tariff or DEWA compliance layer. Price is not one of Aurora’s weaknesses: Basic at US$1,620 a year undercuts SurgePV Individual at US$1,899, and Premium at US$2,640 is close to twice SurgePV’s team seat rather than a wild premium. The gap is what is in the box for the UAE, not the invoice. Detailed in our Aurora Solar alternative writeup.
5. OpenSolar
Best for: one or two person residential outfits in Sharjah and Ajman doing occasional villa work.
Pricing: the core platform is free, and it stays free. OpenSolar has said 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 the rates and they are geo-specific. Until it does, nobody can honestly tell you what a UAE team will pay, and we are not going to invent a number.
Strengths: genuinely free, not free-trial free, decent residential templates, and the lowest barrier of anything in this table for a new contractor.
Weaknesses: commercial projects strain it, and there is no UAE regulatory content, so DEWA tariff logic, approved-equipment filtering and Gulf soiling are all yours to handle outside the tool. On price alone it beats every paid platform here, SurgePV included. The case for paying is the regulatory layer, not the licence maths.

Ranks 6 to 10: The Specialists
6. PVcase
Terrain-aware ground-mount design running on top of AutoCAD, which you need to licence separately. PVcase does not publish a price and sells on quote only, so treat any per-seat figure you see in a software directory as an unverified third-party estimate. For desert ground-mount in the Western Region where slope and wadi drainage drive the racking layout, nothing beats it. It does no rooftop work worth the name, no financial modelling and no proposals, so it sits alongside another tool rather than replacing one. Relevant mainly to teams reading our utility-scale solar design software guide.
7. PV*SOL Premium
Valentin Software prices PVSOL Premium at EUR 845 per named user per year plus VAT, with the standard PVSOL edition at EUR 585. It is a subscription now, not a perpetual licence: perpetual licences bought before 19 November 2024 still run, but maintenance renewals ended on 1 October 2024. Five Premium seats come to EUR 4,225 a year, which is under what five SurgePV seats cost. The 3D obstruction modelling is detailed and the component library is large, which suits consultants doing shading studies on dense villa compounds where neighbouring towers and palm trees matter. Weaknesses: desktop-bound, single-user, no collaboration, no UAE tariff data, and the interface shows its age. Compare with our solar shading analysis software roundup.
8. RatedPower
Automated conceptual engineering for utility-scale plants. RatedPower, now part of Enverus, publishes no price and sells on quote only. The five-figure per-seat numbers that circulate are industry-observed estimates rather than vendor-confirmed, so budget from a real quote. It generates a full 100 MW plant layout including civil works, cabling and a preliminary BOQ in hours. That is genuinely useful for a developer bidding into Emirati tenders. It is irrelevant for anyone under 5 MW, and the price makes it a developer tool rather than a contractor tool.
9. Solargraf
Priced by project volume rather than by seat: Starter is US$2,799 for 240 projects and two users, rising to Enterprise at US$12,999 for 1,500 projects, with API access a further US$4,000 a year on everything except Enterprise. Fast residential quoting with tight Enphase microinverter integration, which suits UAE villa retrofits using module-level electronics to handle partial shading from stairwells and water tanks. Thin engineering depth, no bankable yield output, and no DEWA content.
10. SketchUp plus Skelion
Roughly US$600 per year combined. Architects and consultants already modelling a building in SketchUp can add a PV plugin and get a credible visual and a rough yield. It is a visualisation route, not an engineering one: no string sizing worth trusting, no financial model, no compliance layer. Listed because a real slice of UAE consultancy work still runs this way.
Heat, Dust and Yield: The Numbers That Decide UAE Design
Work an example. A 100 kWp warehouse rooftop in Dubai Investments Park, modelled with European defaults (2 percent soiling, 25C reference behaviour, no inverter thermal throttle) returns roughly 175,000 kWh a year. Model the same roof with a 12 percent soiling figure for a quarterly cleaning schedule, hourly ambient peaking at 50C, and inverter derating above 45C, and you land closer to 152,000 kWh. That 23,000 kWh gap is the entire margin between a performance guarantee met and a dispute. The soiling loss and shading loss definitions in our glossary explain how these stack multiplicatively rather than additively.
Cleaning frequency is a design input, not an operations afterthought. Monthly cleaning in the Gulf typically holds soiling to 3 to 6 percent annually. Quarterly cleaning drifts to 10 to 15 percent. Annual cleaning, which some villa owners default to, can pass 20 percent. Your software should let you enter the interval and see the yield move.
Common Mistakes UAE Design Teams Make
-
1
Sizing strings at 25C. Open-circuit voltage rises as temperature falls, so the cold-morning case sets the maximum string length, while the 55C case sets the minimum for MPPT tracking. Teams that check only one end of the range get nuisance shutdowns in January or lost tracking in July.
-
2
Using non-approved equipment. A module absent from the DEWA approved list will not pass Shams Dubai inspection no matter how good its IEC certification is. Filter the database before the BOQ, not after.
-
3
Oversizing past annual consumption. Shams Dubai banks surplus as credit rather than paying cash, so a system that generates 140 percent of site load has a payback far worse than the proposal claims. Model consumption first.
-
4
Ignoring cable derating in hot conduit. DC cable run through a rooftop tray in Sharjah sits well above 60C. Applying the standard temperature correction factor often pushes the conductor one size up, and the software should show it.
-
5
Applying Dubai rules in Ajman. Shams Dubai is a DEWA programme. Northern-emirate projects fall under Etihad Water and Electricity with different application steps and approved-contractor requirements.
⚠️ Watch out
A tool that lets you set soiling but hides the assumption in a default is more dangerous than one with no soiling model at all, because nobody checks a field they never opened.
Should a UAE Contractor Standardise on One Platform?
- ✓ You ship 5 or more designs a month across emirates
- ✓ You work under both DEWA and EtihadWE rules
- ✓ Client proposals and engineering come from the same team
- ✓ Your add-on spend already exceeds AED 1,500 a month
- ✗ You bid IPP tenders that name PVsyst in the document list
- ✗ You do terrain-heavy desert ground-mount (add PVcase)
- ✗ You are an architecture practice, not a contractor
- ✗ You ship fewer than 2 designs a month
The honest answer for most UAE contractors is one primary platform plus a specialist when a specific bid demands it. Running four tools to cover one workflow is how design teams lose a day a week to re-entry.

Frequently Asked Questions
What is the best solar design software in UAE in 2026?
SurgePV ranks first for UAE work in 2026, scoring 37 of 40 on our four-point bench across regulatory depth, Gulf climate accuracy, workflow coverage and cost. It is US$1,299 per user per year on the 5-User Team plan, US$6,495 for five seats, and bundles DEWA Shams Dubai net metering logic, EtihadWE profiles, 55C ambient derating, configurable dust soiling, AI 3D roof modelling, 8,760-hour shading and white-label proposals. PVsyst remains the pick when a lender or IPP tender explicitly requires PVsyst output.
Does solar design software need to handle DEWA Shams Dubai rules?
Yes, if you work inside Dubai. Shams Dubai is a net metering scheme where surplus generation is banked as credit rather than paid in cash, and systems are sized against annual site consumption. Software that models a cash export tariff will overstate payback significantly. It also matters that only DEWA-enrolled contractors can submit applications and that modules and inverters must appear on DEWA’s approved lists, so equipment filtering inside the tool prevents a rejected submission.
How much does solar design software cost in the UAE?
Vendors bill in their own currencies, so compare in those. OpenSolar’s core platform is free. PVsyst Professional is CHF 700 per user per year. Aurora Basic and HelioScope Basic are both US$1,620 a year, with Aurora Premium and HelioScope Pro at US$2,640. SurgePV is US$1,299 per user per year on the 5-User Team plan and US$1,899 for a single seat. PV*SOL Premium is EUR 845 per named user plus VAT. Solargraf sells by project volume from US$2,799 to US$12,999. PVcase and RatedPower publish no price and quote on request. Note that several of these undercut SurgePV on sticker price, so the UAE argument for SurgePV is the DEWA and EtihadWE regulatory layer, not a cheaper licence.
What soiling loss should I use for a UAE solar design?
Use the cleaning schedule, not a default. Monthly cleaning typically holds annual soiling loss to 3 to 6 percent in the Gulf. Quarterly cleaning drifts to 10 to 15 percent. Annual or ad-hoc cleaning can exceed 20 percent, and heavy shamal dust events make it worse. The 2 percent default shipped by most global platforms is a temperate-Europe figure and will overstate UAE yield by 10 percent or more over the asset life.
What ambient temperature should a UAE solar design use?
Design to 50C to 55C ambient for the summer case, which puts module cell temperature near 75C to 80C on a close-mounted rooftop array. At a temperature coefficient of minus 0.30 to minus 0.35 percent per degree, that is 15 to 18 percent power loss versus the STC nameplate at the hottest hours. Separately, check the winter minimum for open-circuit voltage, because the cold case sets the maximum string length.
Is Etihad Water and Electricity different from DEWA for solar approvals?
Yes. DEWA administers Shams Dubai inside Dubai only. Etihad Water and Electricity covers Sharjah, Ajman, Fujairah, Ras Al Khaimah and Umm Al Quwain with its own application process and approved-contractor requirements, while Abu Dhabi’s large-scale procurement runs through EWEC. Application steps, equipment lists and connection thresholds differ, so a design approved for a Dubai villa cannot be resubmitted unchanged for a Sharjah one.
Can free solar design software work for UAE projects?
For a solo contractor doing occasional villa work, yes, with caveats. OpenSolar’s core platform is free, not a trial, and produces a reasonable residential layout and proposal. It carries no UAE regulatory content, no DEWA equipment filtering and weak soiling controls, so every Gulf-specific assumption is yours to enter manually. OpenSolar has said API Access and Connectors become chargeable from 16 April 2026 but has not published the rates, so the honest position is that the free core stays free and the paid extras are an unknown cost until it publishes them.
Which solar design software do UAE banks accept for project finance?
PVsyst remains the most widely named tool in UAE and wider Gulf project finance documentation, and many IPP tender packs reference it directly. HelioScope output is accepted on commercial-scale deals by several lenders. SurgePV produces P50, P75 and P90 yield reports in the same format and is accepted on C&I deals, but for a large utility-scale bid that names PVsyst in the requirements, run PVsyst for the finance pack and keep your primary platform for everything else.
Stop paying for four tools. Design it all in one.
