How Much Solar Energy is Needed to Power a House in Ghana?
A typical Ghana house needs 3-8kW solar system generating 15-40 kWh daily to meet average electricity consumption. Small homes (2-3 bedrooms) require 3-5kW systems, while larger homes with AC need 6-8kW systems. Ghana houses consume 300-800 kWh monthly, requiring solar systems costing GHS 25,000-80,000 for complete energy independence.
Solar Energy Requirements by House Size in Ghana
Small House (2-3 bedrooms): 3-5kW System
15-25 kWh daily | 450-750 kWh monthly | GHS 25,000-40,000
Medium House (3-4 bedrooms): 5-6kW System
25-30 kWh daily | 750-900 kWh monthly | GHS 40,000-55,000
Large House (4+ bedrooms + AC): 6-8kW System
30-40 kWh daily | 900-1200 kWh monthly | GHS 55,000-80,000
Calculating Your House Solar Needs in Ghana
Energy Consumption Analysis
Review your ECG bills for 12 months to determine average monthly consumption in kWh. Ghana houses typically use 300-1200 kWh monthly. Divide monthly usage by 30 to get daily needs, then divide by 5 (Ghana's average solar hours) to determine required system size in kW.
Ghana Solar System Efficiency
In Ghana's excellent solar conditions (4-6 peak sun hours daily), a 1kW system generates 4-6 kWh daily. Account for system losses (10-15%) and future energy growth when sizing. Include appliances like AC, water heaters, and cooking equipment in calculations for accurate sizing.
