In the UAE the sun is high, the sky is clear, and obstruction shading is a smaller problem than almost anywhere else on this list. That does not make shading analysis easy, it makes it different. The losses that matter here come from array geometry the designer chose, from rooftop plant on dense commercial buildings, and from the way shading interacts with a soiling regime that is severe by global standards.
Direct answer. The best solar shading analysis software in the UAE is PVsyst for anything submitted or financed, because DEWA and the other distribution companies expect a recognisable yield study, and PVsyst is the reference. SurgePV covers the same 8,760-hour shading alongside the layout and single-line diagram for the Shams Dubai submission pack.
TL;DR
- High sun angles mean self-shading between rows, not neighbouring buildings, is the dominant loss.
- Tight inter-row pitch raises capacity per roof but costs winter mornings. That trade is the core UAE design decision.
- Rooftop plant on commercial buildings is the main obstruction. Model it.
- Soiling is severe, and rows packed too tightly are harder to clean, so pitch is a cleaning-access decision too.
- Shams Dubai and the equivalent programmes expect a recognisable yield study, so use a tool the reviewer knows.
What the UAE Actually Changes About Shading Analysis
The sun is high, so obstruction matters less. At around 25 degrees north with clear skies, the sun sits high through most of the productive day. A parapet or a neighbouring building that would remove hours of generation in northern Europe removes a fraction of that here. The annual loss from external obstruction on a typical UAE rooftop is genuinely small, and designers who arrive from a temperate market often over-invest in modelling it.
Self-shading is the real problem. Because external obstruction is modest, the dominant controllable loss is the array shading itself. On a flat commercial roof with tilted rows, pitch is a direct trade between installed capacity and morning and evening losses. Pack the rows and you fit more kilowatts on the roof but lose the shoulders of every winter day. Space them and you lose capacity. This is a calculation, and it is the single most valuable thing hourly software does on a UAE project.
Rooftop plant dominates the obstruction picture. Villas and commercial buildings here carry substantial rooftop equipment: chillers, air handling units, water tanks, lift overruns, and satellite plant. These sit inside the array boundary rather than outside it, so they cannot be handled with a horizon profile. They need to be in a 3D scene.
Pitch is also a cleaning decision. Soiling in the Gulf is severe, and the difference between a cleaned and an uncleaned array is far larger than most shading losses. Rows spaced tightly enough to optimise shading arithmetic can be too tight for a cleaning crew or a robotic system to work between. A pitch that is optimal on paper and unwashable in practice is the wrong pitch.
The submission expects a familiar document. Programmes such as Shams Dubai route the connection through the distribution company, and reviewers see PVsyst outputs constantly. Submitting something unrecognisable adds review cycles for no benefit.

|---|---|---|---|---|
| PVsyst | Submissions and financed studies | Best in class | Yes, scene builder | ~$500 |
| SurgePV | Shading plus design and SLD | Yes, 8,760-hour | Yes | $1,299 to $1,899 |
| HelioScope | Fast C&I layout and shading | Yes | Moderate | ~$1,188 |
| Aurora Solar | Complex roof geometry | Yes | Strong, LIDAR | $1,908 to $3,108 |
| PVcase | Large ground-mount layout | Yes | Terrain-aware | Enterprise quote |
| SketchUp plus Skelion | Bespoke geometry | Manual | Manual | ~$700 plus plugin |
| SAM (NREL) | Sensitivity studies | Yes | Limited | Free |
PVsyst is the default for anything that gets submitted or financed. Its near-shading scene and loss diagram give the pitch trade explicitly, and the output is what a reviewer expects. See PVsyst price.
SurgePV carries the same 8,760-hour shading into string design, the single-line diagram, and DWG export for the submission pack.
PVcase is the right answer at utility scale where terrain and row layout dominate.

What a UAE Shading Deliverable Has to Contain
- Inter-row pitch study comparing at least three candidate pitches on annual yield and installed capacity.
- 3D scene including rooftop plant, chillers, tanks, and lift overruns modelled at real height.
- Hourly shading loss with monthly breakdown.
- Morning and evening loss shown separately, since that is where self-shading concentrates.
- Cleaning access width confirmed against the chosen pitch.
- Per-string loss table identifying compromised positions.
- Soiling assumption stated alongside the shading figure, because the two are usually confused in performance disputes.
Item 5 is the one that gets skipped and then costs money for twenty years. A pitch that wins the yield optimisation by a fraction of a percent and blocks the cleaning crew loses far more than it gained.
Pricing in Dirhams
| Stack | USD per year | Approx. AED at 3.67 | Covers |
|---|---|---|---|
| PVsyst | ~$500 | ~AED 1,835 | Submission-grade shading and yield |
| HelioScope | ~$1,188 | ~AED 4,360 | C&I layout and shading |
| SurgePV | $1,299 to $1,899 | ~AED 4,767 to AED 6,969 | Shading plus full design |
| Aurora | $1,908 to $3,108 | ~AED 7,002 to AED 11,406 | Sales-grade shading plus proposal |
The dirham is pegged to the dollar, so these figures are stable.
What Most UAE EPCs Get Wrong
They pick a row pitch from a rule of thumb and never test it.
A ground coverage ratio inherited from a European project or a supplier’s default sheet gets applied to a Dubai rooftop without anyone running the trade. Sometimes it costs capacity that the roof could have carried. More often it costs the winter shoulders on an array that is already tight. The calculation takes an hour in any hourly tool and it changes the economics of the whole project, which makes skipping it the most expensive shortcut available in this market. Our ground coverage ratio guide covers the arithmetic.
The second mistake is attributing soiling losses to shading, or the reverse, in a performance dispute. State both assumptions separately in the original study and the argument does not happen.
When Software Is Not the Answer
If the roof cannot carry the array at the pitch and ballast the shading study wants, that is structural engineering rather than modelling.
Our solar civil and structural engineering team produces wind-load and ballast designs delivered as STAAD Pro report calculations, with solar rooftop detailed engineering design covering the construction pack. See the sample design pack or talk to our team.
Conclusion
- Run the pitch trade explicitly. Self-shading, not neighbouring buildings, is the dominant controllable loss here.
- Model rooftop plant in 3D. Chillers and tanks sit inside the array boundary and horizon methods cannot see them.
- Check cleaning access against the chosen pitch. An unwashable optimum is not an optimum.

FAQ
What is the best solar shading analysis software in the UAE? PVsyst for anything submitted or financed, because distribution company reviewers expect a recognisable yield study. SurgePV where the same licence also has to produce the layout and single-line diagram.
Does obstruction shading matter much in the UAE? Less than in temperate markets. High sun angles and clear skies mean a parapet or neighbouring building removes a modest share of annual generation. Self-shading between rows is the larger controllable loss.
How should inter-row pitch be decided? By running candidate pitches through an hourly model and comparing annual yield against installed capacity, then checking the winner against cleaning access width. A rule of thumb imported from another market is not a decision.
Why does soiling belong in a shading discussion? Because Gulf soiling losses are large enough to swamp most shading losses, and because the two get confused in performance disputes. State both assumptions separately in the original study.
Does DEWA require a specific shading method? No specific simulation is mandated, but the connection review goes faster with a document the reviewer recognises, which in practice means a standard yield study.
How much does solar shading analysis software cost in the UAE? From roughly AED 1,835 per year for PVsyst alone to AED 11,406 for Aurora’s higher tiers. Full math is in our solar design software pricing breakdown.
