The UAE is four solar markets sharing a currency. DEWA credits Dubai customers at their own slab rate with indefinite rollover. Abu Dhabi’s ADDC and AADC give kWh offset only, no cash, at up to 5 MW per premises. EtihadWE in the Northern Emirates issues credits that expire every December. Sharjah’s SEWA has no published distributed solar programme at all. Layer on an Abu Dhabi residential tariff spread of roughly four to one between subsidised nationals and expatriates, and a software stack configured for one emirate will produce confidently wrong numbers in the others. This guide covers what the UAE stack actually has to handle.
Short version. The best solar software for a UAE business in 2026 is a stack whose core can be configured per utility rather than per country. That is the requirement no international platform meets by default, and it is the one that decides whether your quotes are right in three emirates or one.
This page covers the category as a whole. For the tool-by-tool comparisons see our best solar design software UAE and best solar proposal software UAE guides, and the flat-roof treatment in solar shading analysis software UAE.
Quote the same villa under three utility regimes
A SurgePV engineer takes one of your addresses, applies the correct DEWA, ADDC or EtihadWE credit rule and tariff category, and produces the branded Arabic or English proposal in 20 minutes.

The Six Categories, And The Utility Problem
| Category | What it does | UAE complication |
|---|---|---|
| Design and simulation | Layout, parapet shading, soiling, yield | Flat roofs mean self-shading dominates |
| Proposal and quoting | Credit mechanism, tariff category, payback | Must be configurable per utility, not per country |
| Compliance | ECAS, IEC, approved lists | Equipment eligibility varies by emirate |
| CRM and pipeline | Leads, follow-up, conversion | API connection is sufficient |
| Project execution | Utility application, inspection, energisation | Process differs by utility |
| Monitoring | Performance, service, Scope 2 reporting | Corporate clients increasingly require it |
What Is Genuinely UAE-Specific
Four credit mechanisms, not one. Covered above. The DEWA arrangement is unusually generous because crediting at the consumer’s own slab means a high-consumption villa earns upper-slab value on exported units, which rewards sizing to the roof. The EtihadWE arrangement does the opposite.
Credit expiry as a sizing input. Under EtihadWE, calendar-year credits expire at year-end, so oversizing generates summer surplus that is written off in December. A tool that treats all UAE credit as rolling will recommend the same system in Ras Al Khaimah as in Dubai, and one of those recommendations wastes energy annually for the life of the system.
Abu Dhabi’s tariff categories. The roughly four to one spread between subsidised nationals and expatriates means the same array has completely different economics depending on who occupies the building. The uncomfortable but honest consequence is that solar for a subsidised national household in Abu Dhabi does not pay back on economics alone within a reasonable horizon, and the right software lets you demonstrate that rather than papering over it.
ECAS and approved lists. ECAS certification is mandatory, alongside IEC 61215, 61730, 62109, 62116, 61727 and 60255. Dubai maintains an approved equipment list and Abu Dhabi requires both the design consultant and installation contractor to be listed.
Scope 2 reporting. The Climate Law, Decree-Law 11 of 2024 effective May 2025, requires it with fines from AED 50,000 to 2 million. For corporate buyers this is frequently the actual driver.
Flat roofs and dust. Parapet self-shading and heavy soiling dominate the technical picture. Our solar shading analysis software UAE guide covers both.
Where UAE Teams Overbuy And Underbuy
Underbought: per-utility configuration. The defining gap, and the one that produces wrong quotes rather than merely inefficient ones.
Underbought: credit expiry modelling. Only matters in the Northern Emirates, and matters a great deal there.
Underbought: realistic soiling. A Gulf proposal using European soiling assumptions overstates delivered yield every year of the projection.
Underbought: Scope 2 quantification on commercial work. It is often the reason the buyer is in the room.
Overbought: US-first platforms. Aurora and similar model net metering that has no UAE counterpart in any emirate.
Overbought: seats for viewers. Universal.
Configure per utility, not per country
SurgePV models DEWA slab-rate credits, ADDC kWh offset and EtihadWE calendar-year expiry as separate mechanisms, with tariff categories by customer type.

The Platforms UAE Businesses Should Evaluate
1. SurgePV, the integrated core
Design and proposals from one record, with configurable credit mechanisms for DEWA slab-rate, ADDC offset and EtihadWE expiring credits, tariff categories per customer type, ECAS-aware equipment selection, IEC standards library, configurable soiling and per-edge parapet shading. White-label proposals with e-signature in 9 languages including Arabic. $1,299 to $1,899 per user per year.
2. PVsyst
The bankable simulation reference for large ground-mount, frequently named by lenders and offtakers on regional projects. No proposal layer and no utility credit logic. See our PVsyst alternative review.
3. HelioScope
Solid browser-based engineering for the C&I rooftops that make up much of UAE demand. No proposal layer. Our HelioScope alternative guide covers the trade-offs.
4. Aurora Solar
Strong residential design built around US net metering, which does not exist here in any form. See our Aurora Solar alternative comparison.
5. Enact Solar
Reasonable financing presentation, with no UAE utility or tariff libraries. See our Enact Solar alternative review.
6. Consultant spreadsheets plus PVsyst
The default on large UAE projects. Defensible engineering, and the usual source of one tariff and one export rule applied across emirates.

Worked Example: 300 kW Commercial, Dubai Versus Northern Emirates
An illustrative calculation, not a specific customer project. Inputs: 300 kW DC, 1,750 kWh per kW specific yield, 525,000 kWh generation, 380,000 kWh self-consumed, 145,000 kWh exported, commercial tariff at 44 fils per kWh.
| Line | Dubai, DEWA | Northern Emirates, EtihadWE |
|---|---|---|
| Generation | 525,000 kWh | 525,000 kWh |
| Avoided import at 44 fils | AED 167,200 | AED 167,200 |
| Exported | 145,000 kWh | 145,000 kWh |
| Credits realised | 145,000 kWh, rolls indefinitely | ~95,000 kWh, remainder expires |
| Export value realised | AED 63,800 | AED 41,800 |
| Year 1 benefit | AED 231,000 | AED 209,000 |
The AED 22,000 annual gap comes entirely from credits expiring unused at the calendar year end. A proposal copied from a Dubai template shows AED 231,000 in both columns and is wrong by roughly 10% in one of them, every year, for the life of the system.
The design response matters as much as the number. On the EtihadWE profile the correct answer is either a slightly smaller array or load shifting to raise self-consumption, and neither recommendation is available to a team whose software does not know that credits expire.
Who Should Choose What
- Choose SurgePV if you quote across emirates and need per-utility credit mechanisms and tariff categories in one tool.
- Choose PVsyst where a lender or offtaker names it on large ground-mount, paired with separate quoting.
- Choose HelioScope if your team is engineering-only on C&I rooftops.
- Avoid Aurora and Enact for UAE work. Both assume incentive structures that do not exist here.
After signing, pipeline and follow-up sit in a CRM. QuickEstimate takes the handoff from SurgePV by API.
Four utility regimes, one workflow
DEWA, ADDC, AADC and EtihadWE credit rules, tariff categories, ECAS-aware equipment, Gulf soiling, per-edge parapet shading and Arabic proposals from $1,299 per user per year.
Book a Free DemoThe Bottom Line
The UAE is a per-utility market and most software is built per country.
- Configure by utility. Credit mechanism, capacity ceiling and expiry are all utility-level properties, not national ones.
- Model expiry where it applies. EtihadWE credits are written off each December, which changes the recommended system size.
- Establish the tariff category first. Abu Dhabi’s four to one spread decides whether the project makes sense at all.
