Solar System Sizing Calculator
Enter all appliances you want to run on solar — we calculate the right panels, batteries, and inverter.
Quick-start — load a typical profile
Solar panel
Higher wattage = fewer panels needed = less roof space. Prices are market estimates — Nigerian solar prices shift frequently. Always confirm with your supplier before purchasing.
Battery type
Tubular: uses 50% of capacity (DoD 50%). Cheaper upfront, needs replacement every 3–5 years.
System voltage
12V: small systems · 24V: typical home · 48V: large home or AC-heavy systems
Installation details
Used to calculate cable sizes and lengths in your report.
