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 Portugal. Click on any location for more detailed information.

Explore the solar photovoltaic (PV) potential across 146 locations in Portugal, from Monção to Funchal. 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 Portugal. We will be more than happy to manually add it for you.

Solar Panel Tilt Angle in Portugal

So far based on Solar PV Analysis of 146 locations in Portugal, we've discovered that the ideal angle to tilt solar PV panels in Portugal varies between 36° from the horizontal plane facing South in Monção and 28° from the horizontal plane facing South in Funchal.

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 Portugal, the ideal angle to tilt your solar panels will vary by approx 8 degrees (between 36° from the horizontal plane facing South and 28° from the horizontal plane facing South).

Portugal solar PV Stats as a country

Portugal ranks 32nd in the world for cumulative solar PV capacity, with 1,801 total MW's of solar PV installed. This means that 3.40% of Portugal's total energy as a country comes from solar PV (that's 23rd in the world). Each year Portugal is generating 174 Watts from solar PV per capita (Portugal ranks 29th in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in Portugal?

Yes, there are several incentives for businesses wanting to install solar energy in Portugal. The Portuguese government offers a range of financial incentives and tax breaks for businesses that invest in renewable energy sources such as solar power. These include grants, loans, and tax credits. Additionally, the government has set up a feed-in tariff system which guarantees a fixed price for electricity generated from renewable sources such as solar power. This helps to make investing in solar energy more attractive to businesses.
