How Do i Calculate the system size required?
Calculate the daily energy consumption of your key appliances
Calculation: Device wattage x No of hours used daily(watt hours)
E.g 125 watt T v used for three hours a day consumes 375 watt-hours
Convert the watt hours to kilowatts
Calculation: Divide the watt hours by 1,000
e.g T v Consuming 120 watt hours uses 0.120kWh per day(120 watt hours/1000)
Work out the system size required
-Calculation: Divide the total number of daily kwh used by all your appliances by the no of peak daily sunshine hours at that location.
E.g Lagos -4.5 hours daily peak sunshine hours.So a home consuming 18kwh per day would require a 4 Kw system(18kwh/4)
With these three basic steps, you will be able to decide which system size is suitable for you.
