About solar in Abeokuta
Abeokuta, Nigeria sits near the equator, where day length is stable year-round and the sun passes close to overhead. Its annual peak sun hours average 4.63 kWh/m²/day, a good solar resource by global standards.
The strongest month in Abeokuta is April (spring) at 5.14 kWh/m²/day, and the weakest is August (summer) at 3.58 kWh/m²/day. When sizing a year-round off-grid system, it's standard practice to design against the August value rather than the annual average — otherwise the battery bank runs low during the darkest weeks.
Abeokuta's solar conditions are well within the range where off-grid PV is a straightforward engineering exercise with standard-sized arrays and lithium batteries.
FAQ
- What are the peak sun hours in Abeokuta?
- Abeokuta averages 4.63 peak sun hours per day annually, ranging from 3.58 in August to 5.14 in April.
- How many solar panels do I need in Abeokuta?
- Panel count depends on your daily load. At Abeokuta's annual average of 4.63 kWh/m²/day, a 5 kWh/day load needs roughly 4 × 400 W panels. Use the calculator above for your actual load.
- What size battery do I need in Abeokuta?
- Sizing against Abeokuta's worst month (August, 3.58 kWh/m²/day) with 2 days of autonomy at 80% depth of discharge, a 5 kWh/day load needs about a 12.5 kWh battery bank.
- How does Abeokuta's solar resource compare globally?
- Abeokuta sits in solar zone 3 out of 5 (where 5 is strongest) at 4.63 kWh/m²/day — good by global standards. For reference, top-tier desert sites average ~6.5 and high-latitude cities around 2.5 kWh/m²/day.
- Why doesn't solar output vary much by month in Abeokuta?
- Near the equator, day length is nearly constant year-round and the sun stays close to overhead. In Abeokuta, monthly PSH ranges just from 3.58 to 5.14 kWh/m²/day — variance is driven by wet-season cloud cover, not day length.
- What tilt angle works best for panels in Abeokuta?
- At latitude 7°, panels in Abeokuta work best at a low tilt (roughly 7°) or horizontal. Tracking mounts add little benefit this close to the equator.
- How does the wet season affect solar output in Abeokuta?
- Equatorial wet seasons reduce output through cloud cover, not day length. Abeokuta's worst month (August) still delivers 3.58 kWh/m²/day — design against this value for reliable year-round off-grid use.
