Frequently Asked Questions
Is solar cheaper than generator in Nigeria long term?
Yes, for most Nigerian homes. A generator running 8 hours/day on petrol at ₦700/litre costs ₦25,000–₦40,000/month in fuel alone. A solar system costing ₦2–5 million pays itself back in 3–5 years and then runs virtually free for 10+ more years.
What costs does the solar system calculator include?
The calculation includes panels, batteries, inverter, installation, and a maintenance allowance of 1% per year. It does not include battery replacement (typically needed once in 10 years for lithium), which you should factor into long-term comparisons.
Can I use solar and generator together?
Yes — a hybrid system uses solar as the primary source and the generator as backup for extended cloudy periods or heavy loads. This reduces generator hours significantly and is the most practical approach for most Nigerian businesses and homes.
When does the break-even point typically occur?
For a typical Nigerian home running a 3.5KVA generator 8 hours a day on petrol at ₦700/litre, the break-even against a ₦3 million solar system usually falls at 3–4 years. After that, every month represents pure savings.
