Solar output now
Thinking about panels on your roof, or curious what yours should be making? Guess first. Then see what the live sunlight forecast says a rooftop would make in your city today, over the next 48 hours and across a year, and what it saves on your bill.
Your roof, live
Each bar is the expected output for one hour. The dashed line is what a perfectly clear sky would give, so a gap between them is cloud or dust. Tap a bar to see that hour on the roof.
What eats into solar output in the UAE
A thin film of fine sand blocks light before it reaches the cells. On humid mornings, dew turns it into a crust that wind can't blow away. Studies in the Gulf often find losses of roughly 0.3 to 1% a day on panels that are never cleaned, so a month without cleaning can cost 10% or more. That's why big UAE solar parks clean their panels with robots.
Panels are rated at 25°C, but on a UAE summer roof the cells can run at 60 to 70°C. Each degree above 25 costs about 0.35% of output. So a clear day in January can beat a clear day in July, even though the July sun is higher.
Since 2015, Dubai homes can connect rooftop panels to the DEWA grid. Power you don't use flows to the grid and becomes a credit on later bills. Other emirates have their own rules, so ask your utility.
This is an estimate from a simple model and a weather forecast, not a quote. For a real system, ask an installer approved by DEWA (Shams Dubai) or by your emirate's utility for a site survey.
Sources: Live sunlight, temperature and wind forecast from the Open-Meteo forecast API (national weather model data). Tariffs: DEWA slab tariff page (23, 28, 32 and 38 fils per kWh, fuel surcharge for October 2026 of 6 fils, plus 5% VAT); Abu Dhabi Department of Energy regulated tariffs for ADDC and AADC; SEWA and Etihad WE values are typical. Shams Dubai: DEWA's net metering programme, launched in 2015. Typical sunshine (about 2,000 kWh per m² a year on flat ground) and rooftop yields of about 1,500 to 1,800 kWh per kWp a year: Global Solar Atlas (World Bank and Solargis). Heat loss: typical silicon panel datasheets (about 0.3 to 0.4% per °C). Dust losses: published soiling studies in the Gulf. Sun position: a standard low-precision solar position formula. Your location is used only to ask Open-Meteo for the forecast and is not saved.
