Solar PV Analysis of Dubai, United Arab Emirates
The location in Dubai, United Arab Emirates (latitude: 25.2633, longitude: 55.3087) is highly suitable for generating solar power due to its consistently high average daily solar irradiance throughout the year. On average, each kW of installed solar panels can generate 7.42 kWh/day in Summer, 5.74 kWh/day in Autumn, 4.78 kWh/day in Winter, and 7.28 kWh/day in Spring at this location.
To optimize energy production from solar panels at this site, it is recommended to tilt them at an angle of 23 degrees facing southward. This will ensure maximum exposure to sunlight during all seasons and enable efficient energy generation year-round.
While Dubai's climate generally favors solar power generation, there are some local factors that could potentially impede optimal performance of the panels. These include sandstorms and high humidity levels which can reduce sunlight penetration by creating a hazy atmosphere or blocking direct sunlight altogether.
Moreover, dust accumulation on the surface of the panels may also decrease their efficiency over time if not properly maintained through regular cleaning with water or air pressure systems.
Despite these challenges, taking appropriate preventative measures such as installing protective covers or implementing regular maintenance routines can help ensure greater energy production from solar installations in Dubai while mitigating potential adverse effects caused by weather conditions unique to this region.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 8 locations across United Arab Emirates. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Dubai
Seasonal solar PV output for Latitude: 25.2633, Longitude: 55.3087 (Dubai, United Arab Emirates), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
Ideally tilt fixed solar panels 23° South in Dubai, United Arab Emirates
To maximize your solar PV system's energy output in Dubai, United Arab Emirates (Lat/Long 25.2633, 55.3087) throughout the year, you should tilt your panels at an angle of 23° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Dubai, United Arab Emirates
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Dubai, United Arab Emirates. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 23° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 9° South in Summer | 30° South in Autumn | 41° South in Winter | 18° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Dubai, United Arab Emirates
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Dubai, United Arab Emirates.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Dubai, United Arab Emirates
The topography around Dubai is generally flat, with some areas of low hills and sand dunes. The surrounding area is mostly desert, with some coastal areas along the Persian Gulf. Areas that are most suitable for large-scale solar PV in the vicinity of Dubai include open desert plains, coastal areas, and rooftops in urban or suburban settings. Open desert plains provide an ideal environment for large-scale solar PV installations due to their abundant sunshine and lack of obstructions from buildings or trees. Coastal areas also offer a good location for solar PV installations as they benefit from both direct sunlight and cooling sea breezes. Additionally, rooftops in urban or suburban settings can be used to install small-to-medium sized solar PV systems which can help reduce energy costs while contributing to renewable energy goals.
United Arab Emirates solar PV Stats as a country
United Arab Emirates ranks 27th in the world for cumulative solar PV capacity, with 2,705 total MW's of solar PV installed. Each year United Arab Emirates is generating 273 Watts from solar PV per capita (United Arab Emirates ranks 17th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in United Arab Emirates?
Yes, there are several incentives for businesses wanting to install solar energy in the United Arab Emirates. The UAE government has implemented a number of initiatives to encourage businesses to switch to renewable energy sources such as solar power. These include:
1. The Shams Dubai Initiative – This initiative provides financial support and technical assistance for businesses that want to install solar panels on their rooftops or other areas of their property. It also offers subsidies for the installation costs and maintenance fees associated with the project.
2. The Masdar City Solar Park – This is a large-scale solar park located in Abu Dhabi which provides businesses with access to clean, renewable energy at competitive prices.
3. Net Metering – This program allows businesses to sell excess electricity generated from their solar systems back into the grid, providing them with additional income streams from their investments in renewable energy sources.
