What is the Best Size Solar System for a House in Ghana?

Factors Determining Best Solar Size in Ghana
Energy Consumption Pattern
Analyze your ECG bills for the past 12 months to determine average monthly kWh usage. Ghana households typically use 400-1000 kWh monthly. The best system size should cover 80-100% of your consumption to maximize savings while accounting for Ghana's net metering policies.
Roof Space and Budget Considerations
Available roof space determines maximum system size - each kW requires about 60-80 sq ft in Ghana. Budget considerations include upfront costs, financing options, and payback period. A 5kW system typically pays for itself in 4-6 years through electricity savings in Ghana. Naiko Solar provides personalized system sizing for Ghana houses based on your specific needs and budget.
