Lagos, Nigeria, located at latitude 6.5243793 and longitude 3.3792057, is a suitable location for solar power generation due to its relatively consistent sunlight exposure throughout the year. The average daily energy production per kW of installed solar capacity in each season is as follows: 4.46 kWh/day in Summer, 5.21 kWh/day in Autumn, 5.32 kWh/day in Winter, and 5.37 kWh/day in Spring, with Spring typically yielding slightly higher output due to increased sunlight levels.

For optimal energy production from a fixed panel installation at this location, it is recommended to tilt the panels at an angle of 7 degrees facing South.

However, it should be noted that Lagos experiences heavy rainfall during its wet season which may temporarily reduce sunlight availability and subsequently impact solar power generation efficiency during those periods. To mitigate potential losses caused by these weather conditions, proper maintenance of the solar panels (such as regular cleaning) and ensuring adequate drainage around the installation site can help maintain optimal energy production levels throughout the year.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 50 locations across Nigeria. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Ideally tilt fixed solar panels 7° South in Lagos, Nigeria

To maximize your solar PV system's energy output in Lagos, Nigeria (Lat/Long 6.5243793, 3.3792057) throughout the year, you should tilt your panels at an angle of 7° 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.

At Latitude: 6.5243793, Longitude: 3.3792057, the ideal angle to tilt panels is 7° South

Seasonally adjusted solar panel tilt angles for Lagos, Nigeria

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 Lagos, Nigeria. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 7° South tilt angle throughout the year.

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 Lagos, Nigeria

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 Lagos, Nigeria.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Lagos, Nigeria

The topography around Lagos, Nigeria is mostly flat with some small hills and lowlands. Areas nearby that would be most suited to large scale solar PV are the coastal regions due to their higher amounts of direct sunlight and lower levels of cloud cover. The coastal areas also tend to have more open spaces which can be used for larger installations. Additionally, areas near the city center or other urbanized areas may be well suited as they often have less vegetation blocking the sun's rays.
