Frequently Asked Questions
How long do solar panels last?
Most solar panels last 25-30 years. They come with 25-year performance warranties, meaning they'll still produce at least 80% of their original output after 25 years.
Do solar panels work on cloudy days?
Yes! Solar panels still generate electricity on cloudy days, though at reduced efficiency (typically 25-40% of normal output). The batteries store enough energy to power your home even during extended cloudy periods.
How many solar panels do I need for my house?
It depends on your power consumption. A typical 3-bedroom house needs 4-6 panels (400W each) for a 3-5kVA system. Use our free consultation to get a custom recommendation.
What size inverter do I need?
Add up the wattage of all appliances you want to run simultaneously, then add 20-30% buffer. For example, if your appliances total 2,000W, a 2.5kVA inverter is ideal.
How much does solar installation cost?
Installation costs ₦50,000 – ₦200,000 depending on system size and complexity. SteadVolt offers free installation consultation and can connect you with certified installers.
