Solar PV Analysis of Lekki, Nigeria
Lekki, Lagos, Nigeria is a great location for generating solar energy all year round. This is because it's located in the Tropics where sunlight is pretty much constant throughout the year. The amount of electricity you can get from each kilowatt of solar power installed varies slightly by season but not by much: 4.38 kilowatt-hours per day in summer, and around 5.25 kilowatt-hours per day in autumn, winter and spring.
The best times to generate solar power at this location are during autumn, winter and spring when the output is highest. However, even during summer when the output drops slightly to 4.38 kWh/day, it's still a good time to generate solar power due to consistent sunlight.
If you're planning on installing fixed panel solar PVs here, tilting your panels at an angle of 7 degrees South will give you the best overall production across all seasons.
In terms of factors that could potentially impede solar production at this location - there aren't many significant ones due to its tropical climate with plenty of sunshine throughout most of the year. One thing worth noting though would be periods within wet seasons which might see more cloud cover or rainfall reducing direct sunlight exposure on panels - but these are generally short-lived given its tropical climate nature.
To ensure greater energy production despite these occasional weather changes; consider installing tracking systems that adjust panel positions following sun’s path across sky maximizing exposure or using high-efficiency modules that perform better under diffused light conditions like those found on cloudy days.
Another factor could be dust accumulation on panels especially if area experiences frequent sandstorms/dust storms or construction activities nearby – regular cleaning/maintenance would help ensure optimal performance here.
Lastly while Lekki isn’t prone to extreme weather events like hurricanes/tornadoes – if such rare event were expected taking precautions like securing installations properly & having robust insurance coverage can help mitigate potential damages.
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 Lekki
Seasonal solar PV output for Latitude: 6.4061, Longitude: 4.0902 (Lekki, 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 Lekki, Nigeria
To maximize your solar PV system's energy output in Lekki, Nigeria (Lat/Long 6.4061, 4.0902) 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 Lekki, 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 Lekki, 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 Lekki, 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 Lekki, 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 Lekki, Nigeria
Lekki, Nigeria is located in the coastal region of the country. The topography mostly consists of flat plains with an elevation close to sea level. It's characterized by sandy soil due to its proximity to the Atlantic Ocean. The area also has several lagoons and water bodies like the Lagos Lagoon and Lekki Lagoon.
Given this topography, large scale solar PV installations could be suitable in areas that are relatively dry and have less cloud cover for maximum sunlight exposure. These areas should ideally be flat for easy installation of solar panels.
However, it's important to consider that being a coastal region, there might be issues related to high humidity levels, salt mist corrosion and potential flooding which can affect the performance of solar PV systems over time.
Therefore, while selecting a location for large-scale Solar PV within or near Lekki, it would be wise to choose locations slightly inland away from direct coastal influences but still within regions having significant sunlight intensity throughout most parts of the year.
Detailed site surveys would need to be conducted before deciding on specific locations considering these factors along with other practical aspects such as land availability, access roads for maintenance etc.
