Solar PV Analysis of Sangotedo, Nigeria
Sangotedo, Lagos, Nigeria is a great place for generating solar energy all year round because it's located in the tropics where there is consistent sunlight throughout most of the year. The amount of energy that can be generated from solar panels depends on the season. In Summer, you can expect to generate about 4.46 kilowatt-hours (kWh) per day for each kilowatt (kW) of solar panels installed. This increases to around 5.21 kWh/day in Autumn, 5.32 kWh/day in Winter and peaks at around 5.37 kWh/day in Spring.
This means that while you can generate good amounts of energy throughout the year, Spring would be the most ideal time due to slightly higher daily generation rates.
For a fixed panel installation at this location, tilting your panels at an angle of 7 degrees towards the South will allow you to make the most out of your solar PV system throughout all seasons.
However, there are some factors that could affect how much energy you're able to produce from your solar system in Sangotedo.
Environmental factors such as dust and dirt could accumulate on your panels and block sunlight from reaching them which reduces their efficiency over time. Regular cleaning would help maintain their performance.
Weather conditions like heavy rainfall during wet seasons could also potentially damage your panels or cause temporary reduction in generation due to cloud cover but this should not significantly affect annual production too much given high levels of sun exposure across other times during a typical year.
Topographical factors such as tall buildings or trees surrounding your installation site could cast shadows onto your panels and reduce their output so choosing an unobstructed location would be best if possible.
To ensure greater production despite these potential challenges, regular maintenance including cleaning off dust and dirt accumulation; ensuring secure installation against weather elements; and choosing an optimal location free from tall obstructions should be considered when installing a solar PV system at this location.
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.

Solar output per kW of installed solar PV by season in Sangotedo
Seasonal solar PV output for Latitude: 6.4775, Longitude: 3.6327 (Sangotedo, Nigeria), 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 7° South in Sangotedo, Nigeria
To maximize your solar PV system's energy output in Sangotedo, Nigeria (Lat/Long 6.4775, 3.6327) 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.
Seasonally adjusted solar panel tilt angles for Sangotedo, 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 Sangotedo, Nigeria. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 7° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 10° North in Summer | 13° South in Autumn | 22° South in Winter | 0° 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 Sangotedo, 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 Sangotedo, Nigeria.
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 Sangotedo, Nigeria
Sangotedo is located in the southwestern part of Nigeria, near the coast. The topography of this area is relatively flat and low-lying, with some undulating terrain. It has a tropical wet and dry climate, with a long rainy season and a shorter dry season.
In terms of solar PV suitability, areas that are flat or gently sloping would be most suitable as they would minimize installation costs and maximize exposure to sunlight. Given Sangotedo's coastal location, it may also benefit from consistent sunlight levels throughout the year.
The nearby areas such as Ibeju-Lekki could potentially be suitable for large-scale solar PV installations due to its flat terrains. Also, Epe which is slightly inland but still in proximity to Sangotedo could provide good conditions for solar power generation because it has more land area available for such projects.
However, it's important to note that technical feasibility isn't the only consideration when planning large-scale solar installations - factors like access to grid infrastructure, local regulations about land use and environmental impacts must also be taken into account.
