Use our calculator to estimate the solar system size you need based on your appliances and usage.
No appliances added yet. Add your appliances above to calculate your solar needs.
For appliances used at night or day & night, you can specify individual battery usage hours. This allows for smart battery sizing based on actual usage patterns.
Average hours of full sunlight per day. Nigeria typically has 4-6 peak sun hours depending on location and season.
Overall system efficiency accounting for losses in wiring, inverter, and other components. Typical range is 75-85%.
Wattage per solar panel. Common sizes are 400W, 450W, or 550W. Higher wattage panels require fewer panels but may cost more.
Extra panel capacity for cloudy days, dust accumulation, and panel degradation over time. Typically 20-40%.
How much of the battery capacity can be used. Lithium batteries typically allow 80-90% DoD, while lead-acid batteries are limited to 50%.
Efficiency of the inverter in converting DC to AC power. Quality inverters typically have 90-95% efficiency.
Extra capacity added to inverter sizing for safety margin and surge loads. Typically 20-30%.
