The UAE is four solar markets wearing one flag, and a design tool that treats it as one country will get the economics wrong in at least three of them. DEWA credits exports at the consumer’s own slab rate with indefinite rollover and a 1 MW per plot cap. ADDC and AADC in Abu Dhabi offer kWh offset only with no cash payment, at 5 MW per premises, against a tariff that varies by a factor of four between subsidised nationals and expatriates. EtihadWE in the Northern Emirates expires credits at year-end. Sharjah has no broadly available programme at all. This guide compares the platforms UAE installers should shortlist, judged on whether they can model the specific utility rather than a generic net metering assumption.
Short version. The best solar design software for UAE installers in 2026 is SurgePV, because the four utility regimes differ on capacity limits, credit mechanism and credit expiry, and the design tool has to model the specific utility. SurgePV also carries the IEC standards the emirates mandate and produces the proposal from the same record. PVsyst remains the bankable reference for large ground-mount. Aurora models US net metering structures that do not exist here.
The UAE combines high irradiance, low soft costs, and a regulatory environment that is genuinely well organised by regional standards. The complication is fragmentation, and it falls entirely on whoever prepares the design. For the broader category comparison see our solar design software buyer’s guide and the best solar design software ranking.

The Four Utility Regimes, Side By Side
| Utility | Coverage | Capacity limit | Credit mechanism | Credit expiry |
|---|---|---|---|---|
| DEWA Shams Dubai | Dubai | 1 MW per plot | Consumer’s own slab rate | Indefinite rollover |
| ADDC / AADC | Abu Dhabi, Al Ain | 5 MW per premises | kWh offset, no cash payment | Indefinite accumulation |
| EtihadWE | Ajman, UAQ, RAK, Fujairah | Aggregate cap, first-come | Calendar-year kWh credits | Expires at year-end |
| SEWA | Sharjah | No published programme | No published mechanism | Not applicable |
The Abu Dhabi tariff structure deserves separate attention because it is the most commonly mishandled. Subsidised UAE national rates at 6.7 to 7.5 fils per kWh mean avoided import is worth roughly a quarter of what it is worth to an expatriate household at 26.8 to 30.5 fils. A design tool that models one residential tariff for the emirate will produce a payback figure that is wrong by a factor of four for one of those two customers. SurgePV’s ADDC solar guide and AADC Al Ain guide set out the detail.
Approval, Equipment And Contractor Categories
Dubai. Approval runs in four stages: NOC via the Hab Reeh platform as a digital self-assessment, DEWA design approval, installation by an approved contractor, then inspection and bidirectional meter activation. Contractors fall into three categories by system size, being A up to 50 kW, B from 50 to 150 kW, and C above 150 kW. The contractor must be DEWA-certified and is responsible for submitting the application. Equipment must appear on DEWA’s approved list. See SurgePV’s DEWA Shams Dubai guide.
Abu Dhabi. Five stages: RSB approval, design submission to ADDC or AADC, signing the PV Connection Agreement, installation and inspection, then utility installation of the bidirectional meter. Both the design consultant and the installation contractor must appear on the relevant utility’s approved list, and the lists are utility-specific rather than shared. The Abu Dhabi Electricity Wiring Regulations 2020 are mandatory for all work.
Everywhere. ECAS certification from the Ministry of Industry and Advanced Technology is required on all solar equipment sold in the UAE, covered in SurgePV’s ECAS certification guide. The mandatory IEC set is 61215 and 61730 for panels, 62109-1, 62109-2 and 62116 for inverters, 61727 for the grid interface, and 60255 for protection relays.
The legal basis is Federal Decree-Law 17 of 2022 on distributed renewable energy. Separately, the Climate Law, Decree-Law 11 of 2024 effective May 2025, requires Scope 2 emissions reporting with fines from AED 50,000 to 2 million, which is increasingly what drives corporate rooftop demand here.
What The Climate Does To The Yield Model
Two UAE-specific effects belong in any credible simulation, and generic temperate defaults handle neither well.
Thermal derating. Sustained high ambient temperatures push module cell temperatures well above test conditions for much of the year. A thermal model tuned for European conditions will overstate output. This is not a small correction in a Gulf summer.
Soiling. Dust accumulation between cleaning cycles produces losses that vary with cleaning frequency and season. A design that assumes a European soiling default will overstate annual yield, and a proposal built on it will underdeliver. The honest approach is to model the customer’s actual intended cleaning schedule and show the sensitivity.
Both push toward an 8,760-hour engine with configurable soiling and a proper thermal model rather than a simplified annual estimate. Our PV yield simulation software guide covers the methodology.
The Six Platforms UAE Installers Should Evaluate
1. SurgePV, the all-in-one pick
Configurable export credit mechanisms so DEWA slab-rate, ADDC offset and EtihadWE expiring credits can each be modelled properly, IEC standards library, 8,760-hour module-level shading with configurable soiling and a real thermal model, AI 3D roof modeling, bankable P50, P75, P90, and white-label proposals with e-signature in 9 languages including Arabic. $1,299 to $1,899 per user per year.
2. PVsyst
The bankable reference for large UAE ground-mount and utility projects, and frequently named by lenders and offtakers on those. Windows desktop, no proposal layer, no utility-specific credit logic. See our PVsyst alternative review.
3. HelioScope
Credible browser-based engineering simulation for C&I rooftops, which is a large share of UAE demand. No proposal layer and no local incentive modelling. Our HelioScope alternative guide covers the trade-offs.
4. Aurora Solar
Deep residential design built for US net metering, a structure that does not exist in any emirate. Poor fit despite being good software. See our Aurora Solar alternative comparison.
5. PVcase
Useful for large UAE ground-mount terrain work where utility-scale pipelines justify it. Narrow scope, pairs with a design-to-proposal platform. See our PVcase alternative comparison.
6. Consultant spreadsheets plus PVsyst
The default on large UAE projects. Workable, and the usual source of one export assumption being applied across emirates.

Worked Example: 20 kW Villa Rooftop, Dubai Versus Abu Dhabi Expat Versus Abu Dhabi National
An illustrative calculation, not a specific customer project. Inputs: 20 kW DC, 1,750 kWh per kW specific yield, 35,000 kWh generation, 22,000 kWh consumption, 13,000 kWh exported.
| Line | Dubai, DEWA | Abu Dhabi, expat | Abu Dhabi, UAE national |
|---|---|---|---|
| Import tariff | 38 fils per kWh | 28 fils per kWh | 7 fils per kWh |
| Avoided import value | AED 8,360 | AED 6,160 | AED 1,540 |
| Export credited at | Own slab, 38 fils | kWh offset, 28 fils | kWh offset, 7 fils |
| Export value | AED 4,940 | AED 3,640 | AED 910 |
| Year 1 benefit | AED 13,300 | AED 9,800 | AED 2,450 |
The same villa rooftop returns five and a half times more in Dubai than for a subsidised national household in Abu Dhabi. That is not a modelling nuance, it is the difference between a four year payback and a twenty year one, and it is invisible to any tool carrying a single national tariff. It is also why UAE national residential is generally not a solar market on economics alone, and why the honest recommendation there is often a smaller system justified on sustainability reporting rather than payback.
Who Should Choose What
- Choose SurgePV if you work across emirates, need per-utility credit modelling, or want design and proposals from one license.
- Choose PVsyst where a lender or offtaker names it on large ground-mount.
- Choose HelioScope if your team is engineering-only on C&I rooftops.
- Choose PVcase for utility-scale terrain work alongside a proposal platform.
- Avoid Aurora here. US net metering logic has no counterpart in any emirate.
Four utility regimes, one license
DEWA, ADDC, AADC and EtihadWE credit mechanisms, IEC standards, soiling and thermal modelling, AI 3D roof modelling and Arabic proposals from $1,299 per user per year.

The Bottom Line
The UAE rewards installers who treat it as four markets. The utility, not the country, sets the capacity limit, the credit mechanism and whether credits survive to next year.
- Identify the utility before designing. DEWA, ADDC, AADC and EtihadWE differ on every variable that matters, and Sharjah has no published route at all.
- Model soiling and heat explicitly. A European default overstates Gulf yield, and the customer discovers it in July.
