Solar PV Analysis of Akure, Nigeria
Akure, Ondo State, Nigeria, situated at latitude 7.2584 and longitude 5.1897, presents a promising location for solar energy generation. Located in the tropics, this area benefits from consistent sunlight throughout the year, with seasons primarily characterized by wet and dry periods rather than traditional temperature-based seasons.
Solar Energy Potential
The solar energy potential in Akure is impressive, with relatively high and stable electricity output across all meteorological seasons. Spring sees the highest production at 5.56 kWh per day for each kilowatt of installed solar capacity, closely followed by winter at 5.52 kWh/day. Autumn yields 5.32 kWh/day, while summer, though slightly lower, still produces a respectable 4.56 kWh/day.
These figures indicate that Akure is an ideal location for year-round solar energy generation, with only minor fluctuations between seasons. The consistency in output makes it an excellent choice for reliable solar power production throughout the year.
Optimal Panel Installation
For fixed panel installations in Akure, Ondo State, the ideal tilt angle to maximize year-round solar production is 8 degrees facing South. This relatively shallow angle is due to the location's proximity to the equator, where the sun's path is more directly overhead throughout the year.
Environmental Considerations
While Akure's tropical climate is generally favorable for solar energy production, there are some environmental factors to consider:
- Dust and pollution: The dry season may bring increased dust, which can accumulate on solar panels and reduce efficiency.
- Heavy rainfall: During the wet season, frequent and intense rainfall could temporarily reduce solar output.
To mitigate these issues, regular cleaning and maintenance of solar panels is crucial. Installing panels at the recommended angle will also help with natural cleaning during rainfall. Additionally, using high-quality, weather-resistant solar equipment designed for tropical climates can ensure optimal performance and longevity.
In conclusion, Akure's location offers excellent potential for solar energy generation, with consistent and high output throughout the year. With proper installation and maintenance, solar PV systems in this area can provide a reliable and sustainable source of electricity.
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 Akure
Seasonal solar PV output for Latitude: 7.2584, Longitude: 5.1897 (Akure, 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 8° South in Akure, Nigeria
To maximize your solar PV system's energy output in Akure, Nigeria (Lat/Long 7.2584, 5.1897) throughout the year, you should tilt your panels at an angle of 8° 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 Akure, 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 Akure, Nigeria. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 8° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 9° North in Summer | 14° South in Autumn | 23° South in Winter | 1° 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 Akure, 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 Akure, 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 Akure, Nigeria
The topography around Akure, Nigeria is characterized by a mix of gently rolling hills and relatively flat plains. Akure itself is situated in a lowland area, with elevations generally ranging from about 250 to 400 meters above sea level. The surrounding landscape is part of the tropical rainforest belt, which means it's typically lush and green, with dense vegetation in many areas.
To the north and northeast of Akure, the terrain gradually becomes more hilly as it transitions into the Nigerian plateau region. These areas have slightly higher elevations, sometimes reaching up to 500 meters or more. To the south and southwest, the land tends to be flatter, eventually giving way to coastal plains as you approach the Atlantic Ocean, though this is quite far from Akure itself.
The region experiences a tropical climate with distinct wet and dry seasons. During the rainy season, which typically runs from April to October, the area receives significant rainfall, which can impact the landscape and create numerous small streams and rivers.
When considering areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, several factors come into play. Ideally, you'd want relatively flat or gently sloping land with good exposure to sunlight throughout the day. Areas to the north and northeast of Akure, where the terrain becomes more elevated, might offer good potential sites. These higher grounds could provide better sun exposure and potentially less interference from vegetation.
However, it's important to note that the dense vegetation in the region could pose challenges for solar installations. Areas where the forest has been cleared for agriculture or other purposes might be more suitable, as they would require less land preparation. The outskirts of Akure, where there's a transition from urban to rural landscapes, could also offer potential sites that balance good sun exposure with proximity to existing infrastructure.
Ultimately, while the topography around Akure is generally favorable for solar PV, the choice of specific sites would require detailed local surveys. Factors such as land ownership, proximity to power grids, and local climate variations would all need to be considered alongside the topographical features to determine the most suitable locations for large-scale solar projects.
