How Many Solar Panels to Power a House in Ghana?

Most houses in Ghana need 8-15 solar panels to meet their electricity needs. A typical 3-bedroom home in Ghana requires 10-12 panels (450W each), while larger homes may need 15-20 panels. The exact number depends on your energy consumption, appliances used, and Ghana's excellent solar conditions with 4-6 kWh/m²/day of solar irradiance.

Factors Affecting Solar Panel Needs in Ghana

Energy Consumption Patterns

The number of solar panels needed for your Ghana house depends on your monthly electricity consumption (check your ECG bill), appliance types (especially air conditioning), occupancy patterns, and energy efficiency measures. Ghana's hot climate means AC usage significantly increases panel requirements.

Ghana's Solar Advantages

Ghana's excellent solar conditions mean fewer panels are needed compared to less sunny countries.
