Appliance Units Formula
Monthly units = watts x quantity x hours per day x days per month divided by 1000. For example, four 75W fans used for 12 hours daily for 30 days consume about 108 units per month.
Use This for Solar Planning
Appliance-based usage is useful when your electricity bill is not available. For a complete solar estimate, use the total monthly units with roof condition, daytime usage, system type, and current net-metering assumptions.
