Solar PV Analysis of Gwagwalada, Nigeria
Gwagwalada, FCT, Nigeria is a great location for year-round solar energy production due to its consistent sunlight throughout the year. The electricity output per kilowatt of installed solar varies by season, but it's relatively high all year round. In Summer, you can expect about 4.88 kilowatt-hours (kWh) per day; in Autumn, that goes up to 5.78 kWh/day; in Winter it peaks at 6.30 kWh/day; and in Spring it slightly decreases to 6.10 kWh/day.
The best times of the year for generating solar power at this location are during Winter and Spring when the daily output is highest.
A fixed panel installation should be tilted at an angle of around 10 degrees towards the South for optimum results over the course of a full year.
However, there may be local factors that could affect solar production in Gwagwalada such as dust storms or heavy rainfall during wet seasons which could cover panels and reduce their efficiency. To help counteract these issues:
1) Regular cleaning: Dust can accumulate on panels reducing their efficiency so regular cleaning is important especially after dust storms.
2) Installation method: If rainfall is heavy and frequent then installing panels at an angle will allow rainwater to wash away any dirt or debris.
3) Use of micro-inverters: These devices convert DC power generated by individual panels into AC power thus if one panel gets covered with dust or shaded by clouds others continue producing energy efficiently.
4) Weather-resistant equipment: Using weather-resistant mounting systems can protect against damage from severe weather conditions like heavy rains or strong winds.
In summary, while there might be some environmental challenges related to weather conditions, these can be managed effectively with proper maintenance and installation methods making Gwagwalada a very suitable location for harnessing solar energy throughout the year considering its abundant sunshine availability.
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 Gwagwalada
Seasonal solar PV output for Latitude: 8.9419, Longitude: 7.0834 (Gwagwalada, 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 10° South in Gwagwalada, Nigeria
To maximize your solar PV system's energy output in Gwagwalada, Nigeria (Lat/Long 8.9419, 7.0834) throughout the year, you should tilt your panels at an angle of 10° 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 Gwagwalada, 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 Gwagwalada, Nigeria. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 10° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 7° North in Summer | 15° South in Autumn | 25° South in Winter | 3° South 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 Gwagwalada, 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 Gwagwalada, 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 Gwagwalada, Nigeria
Gwagwalada is located in the Federal Capital Territory of Nigeria. The area is characterized by a mix of flat plains and hilly terrain, with some areas covered by savannah vegetation. The region experiences a tropical wet and dry climate, which means it gets plenty of sunshine throughout the year.
Given this topography and climate, flat plains would be ideal for large-scale solar PV installations as they offer unobstructed exposure to sunlight. Additionally, these areas are typically easier to develop since they require less site preparation compared to hilly terrains.
Areas around Gwagwalada such as Dobi, Kutunku and Giri could potentially be suitable for such installations considering their relatively flat terrain. However, a detailed feasibility study that considers factors like land availability and ownership, proximity to transmission lines or load centers (for electricity export), environmental impacts among others should be undertaken before deciding on specific sites for large-scale solar PV projects.
It's also worth noting that Nigeria has significant solar potential due to its location near the equator. This makes it an attractive destination for investments in renewable energy infrastructure like solar farms.
