Most UAE solar proposals are not sold to homeowners. They are sold to facility managers, industrial owners, and building landlords who will read the yield assumptions carefully and ask what happens when nobody cleans the array. That is a different sales document from a residential proposal, and most proposal software is built for the residential one.
Direct answer. The best solar proposal software in the UAE for most EPCs is SurgePV, because Gulf sales are technical and the proposal has to carry a credible yield basis, a soiling and cleaning assumption, and a single-line diagram from the same model. PVsyst alongside it supplies the bankable yield number for anything financed. Residential-oriented tools like Aurora and OpenSolar are a poor fit for a market that is overwhelmingly commercial.
TL;DR
- The UAE market is commercial and industrial, not residential. The buyer is technical and the proposal has to survive scrutiny.
- Soiling and the cleaning regime belong in the proposal, because they are the difference between the modelled yield and the real one.
- Dubai banks net metering credits rather than paying cash, so the savings model is consumption offset, not export revenue.
- Slab tariffs and demand charges mean the value of a kilowatt-hour depends on where the customer sits in the tariff structure.
- Many deals are structured as power purchase agreements or leases, so the proposal is often a financial instrument as much as a technical one.
What the UAE Actually Changes About Proposal Software
The buyer is technical. A UAE commercial solar proposal typically goes to a facilities or engineering function, sometimes with a consultant reviewing it. Rendering quality carries very little weight. What carries weight is whether the yield assumptions are defensible, whether the soiling loss is realistic, and whether the single-line diagram shows a system that will actually pass utility review.
Soiling has to be on the page. The gap between a modelled yield with a temperate soiling default and the real output of an uncleaned Gulf array is large. A proposal that does not state the soiling assumption and the cleaning frequency it depends on is incomplete, and a technical buyer will spot it. Putting the cleaning cost in the operating expense line is more persuasive than hiding it.
Credits, not cash. Dubai’s Shams Dubai net metering banks surplus generation against future consumption. The savings model therefore rewards matching annual consumption rather than maximising generation. Proposal tools built around export revenue model the wrong thing.
Tariff structure decides value. UAE electricity tariffs are structured with consumption slabs and, for larger customers, demand-related components. A kilowatt-hour displaced at the top slab is worth substantially more than one displaced at the bottom. A proposal using a single blended rate understates or overstates depending on where the customer sits.
The commercial structure varies. Many Gulf commercial solar deals are done as power purchase agreements or lease arrangements rather than outright purchase. That makes the proposal a financial document with a tariff, an escalation rate, and a term, and it needs to model those cleanly.
The Platforms Ranked for the UAE
| Platform | Best for | Soiling-aware yield | SLD in same tool | PPA and lease modelling | Price per seat per year |
|---|---|---|---|---|---|
| SurgePV | C&I proposals with technical depth | Yes, configurable | Yes | Yes | $1,299 to $1,899 |
| PVsyst | The bankable yield number | Best in class | No | No | ~$500 |
| HelioScope | Fast C&I layout plus yield | Configurable | No | No | ~$1,188 |
| Aurora Solar | Villa and residential work | Configurable | Limited | Yes | $1,908 to $3,108 |
| OpenSolar | Small residential volume | Basic | No | Yes | $0 plus transaction fees |
| Excel plus PVsyst output | Bespoke PPA structures | Inherited | No | Fully manual | Time |
| Sighten | Financing-led structures | Inherited | No | Extensive | Quote-based |
SurgePV is the practical pick because a Gulf C&I proposal has to carry technical evidence, and producing the yield, the layout, the single-line diagram, and the customer-facing document from one model removes the inconsistencies that technical buyers find. Full technical comparison in best solar design software in the UAE.
PVsyst supplies the number that survives a lender or independent engineer. It is not a proposal tool, and its report is an attachment rather than the document itself. See PVsyst price.
HelioScope is fast for C&I layout and yield. Tiers in HelioScope pricing.
Aurora and OpenSolar are strong residential products in a market that is not primarily residential. Relevant for villa work only. See Aurora Solar pricing and OpenSolar pricing.

What a UAE Commercial Proposal Has to Contain
- System specification with capacity in kWp and kVA, module and inverter selection, and mounting type.
- Yield estimate with the meteorological data source named, and the modelling tool identified.
- Soiling loss and cleaning frequency stated together, with the cleaning cost carried in the operating expense.
- Performance ratio expected in year one and the degradation assumption thereafter.
- Tariff analysis showing the customer’s current slab position and the value of each displaced kilowatt-hour.
- Net metering treatment explaining that surplus is banked as credit, not paid.
- Single-line diagram and connection arrangement.
- Commercial structure, whether outright purchase, lease, or power purchase agreement, with tariff, term, and escalation.
- Roof or ground structural note confirming the mounting approach has been assessed.
Item 3 is the credibility test. A proposal that states the soiling assumption, the cleaning frequency it requires, and the cost of that cleaning reads as honest engineering. One that quietly uses a low default reads as a sales document, and a technical buyer will treat the rest of it accordingly.
Pricing in Dirhams
| Stack | USD per year | Approx. AED at 3.67 | Covers |
|---|---|---|---|
| PVsyst only | ~$500 | ~AED 1,835 | Yield model, no proposal |
| SurgePV | $1,299 to $1,899 | ~AED 4,767 to AED 6,969 | Yield, SLD, and proposal |
| HelioScope | ~$1,188 | ~AED 4,360 | Layout and yield |
| SurgePV plus PVsyst | ~$1,799 to $2,399 | ~AED 6,602 to AED 8,804 | Full stack for financed projects |
The dirham is dollar-pegged, so these figures are stable.
What Most UAE EPCs Get Wrong
They sell a yield number they have not stress-tested against the cleaning budget.
The sequence is familiar. The proposal carries a yield built on a low soiling assumption. The customer signs. Nobody funds a cleaning regime, because it was not in the operating budget the proposal implied. Performance falls short in the first summer, and the EPC spends the warranty period explaining a gap that was designed in at proposal stage. The fix is to state the soiling assumption and its cleaning requirement on the proposal, and price the cleaning as a line item.
The second mistake is modelling savings at a blended tariff. UAE tariffs are slab-structured, and a system sized to shave the top slab has a very different value per kilowatt-hour than one sized to cover base load. Model the slabs.
When Proposal Software Is Not the Constraint
Gulf projects tend to be large, and large projects are won on engineering credibility rather than proposal design. If the constraint is producing detailed engineering, structural calculations, and an owner’s engineer review for MW-scale work, that is a bench problem.
Our MW-scale project management consultancy and solar rooftop detailed engineering design services cover that, and we have delivered an 11 MW DC rooftop project on tin shed in the Gulf. Structural work runs through solar civil and structural engineering. See our projects or talk to our team.
Conclusion
- Put soiling and cleaning on the proposal. It is the assumption that most often separates modelled yield from delivered yield in the Gulf.
- Model the tariff slabs, not a blended rate. Where the customer sits in the structure decides what a displaced unit is worth.
- Explain credit banking clearly. Dubai surplus is banked, not paid, and a customer who expects a cheque will be unhappy.

FAQ
What is the best solar proposal software in the UAE? SurgePV for most C&I EPCs, because a Gulf proposal has to carry technical evidence and the yield, single-line diagram, and customer document should come from one model. PVsyst alongside it for anything financed.
Are residential proposal tools useful in the UAE? Only for villa work. The UAE market is predominantly commercial and industrial, and residential-oriented tools model the wrong buyer and the wrong tariff structure.
How should soiling be handled in a UAE proposal? As an explicit loss figure tied to a stated cleaning frequency, with the cleaning cost carried in the operating expense. Temperate defaults understate Gulf soiling substantially.
Does DEWA pay for exported solar? Dubai’s Shams Dubai arrangement generally banks surplus generation as a credit against future consumption rather than paying cash, so the savings case is consumption offset.
How much does solar proposal software cost in the UAE? From roughly AED 1,835 per year for PVsyst alone to around AED 8,800 for a full yield-plus-proposal stack. Cross-platform math is in our solar design software pricing breakdown.
Do UAE proposals need a single-line diagram? For commercial work, generally yes. Technical buyers and utility-facing consultants expect to see the connection arrangement, and producing it from the same model as the yield avoids inconsistencies.
What about the design software decision separately? Covered in best solar design software in the UAE.
