Below is the average daily output per kW of Solar PV installed for each season, along with the ideal solar panel tilt angles calculated for various locations in Yemen. Click on any location for more detailed information.

Explore the solar photovoltaic (PV) potential across 7 locations in Yemen, from Sa`wan to Aden. We have utilized empirical solar and meteorological data obtained from NASA's POWER API to determine solar PV potential and identify the optimal panel tilt angles for these locations.

Feel free to contact us if you wish for us to include a general Solar PV Analysis for a certain city or location not already listed here for Yemen. We will be more than happy to manually add it for you.

Solar Panel Tilt Angle in Yemen

So far based on Solar PV Analysis of 7 locations in Yemen, we've discovered that the ideal angle to tilt solar PV panels in Yemen varies between 15° from the horizontal plane facing South in Sa`wan and 12° from the horizontal plane facing South in Aden.

These tilt angles are optimised for maximum annual PV output at each location for fixed-panel solar PV installations. If you click on one of the locations above, there is further detail on ideal seasonal tilt angles as well (in case your solar panels are adjustable).

Depending on where you are based in Yemen, the ideal angle to tilt your solar panels will vary by approx 3 degrees (between 15° from the horizontal plane facing South and 12° from the horizontal plane facing South).

Yemen solar PV Stats as a country

Yemen ranks 67th in the world for cumulative solar PV capacity, with 253 total MW's of solar PV installed. Each year Yemen is generating 8 Watts from solar PV per capita (Yemen ranks 75th in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in Yemen?

Unfortunately, there are currently no incentives for businesses wanting to install solar energy in Yemen. The country is facing a severe economic crisis and the government does not have the resources to provide any financial support for renewable energy projects. However, some international organizations such as the World Bank and UNDP have been providing technical assistance to help develop renewable energy projects in Yemen.

Do you have more up to date information than this on incentives towards solar PV projects in Yemen? Please reach out to us and help us keep this information current. Thanks!
