About solar in Masina

Masina, Democratic Republic of the Congo sits near the equator, where day length is stable year-round and the sun passes close to overhead. Its annual peak sun hours average 4.5 kWh/m²/day, a good solar resource by global standards.

The strongest month in Masina is March (autumn) at 5.11 kWh/m²/day, and the weakest is June (winter) at 3.98 kWh/m²/day. When sizing a year-round off-grid system, it's standard practice to design against the June value rather than the annual average — otherwise the battery bank runs low during the darkest weeks.

Masina'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 Masina?
Masina averages 4.5 peak sun hours per day annually, ranging from 3.98 in June to 5.11 in March.
How many solar panels do I need in Masina?
Panel count depends on your daily load. At Masina's annual average of 4.5 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 Masina?
Sizing against Masina's worst month (June, 3.98 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 Masina's solar resource compare globally?
Masina sits in solar zone 3 out of 5 (where 5 is strongest) at 4.5 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 Masina?
Near the equator, day length is nearly constant year-round and the sun stays close to overhead. In Masina, monthly PSH ranges just from 3.98 to 5.11 kWh/m²/day — variance is driven by wet-season cloud cover, not day length.
What tilt angle works best for panels in Masina?
At latitude 4°, panels in Masina work best at a low tilt (roughly 4°) or horizontal. Tracking mounts add little benefit this close to the equator.
How does the wet season affect solar output in Masina?
Equatorial wet seasons reduce output through cloud cover, not day length. Masina's worst month (June) still delivers 3.98 kWh/m²/day — design against this value for reliable year-round off-grid use.
