How do I calculate what size solar system I need?

You can calculate how many solar panels you need by multiplying your household’s hourly energy requirement by the peak sunlight hours for your area and dividing that by a panel’s wattage. Use a low-wattage (150 W) and high-wattage (370 W) example to establish a range (ex: 17-42 panels to generate 11 000 kWh/year).

How is solar design calculated?

the total Watt-peak rating needed for the PV panels needed to operate the appliances.

1. Determine power consumption demands.

Total appliance use = (18 W x 4 hours) + (60 W x 2 hours) + (75 W x 24 x 0.5 hours)
= 1 092 Wh/day
Total PV panels energy needed = 1 092 x 1.3
= 1 419.6 Wh/day.
