How many solar panels do I Need?

You can use this number to figure out how many panels you would need. First, convert kW into Watts by multiplying by 1,000. So 5.2 kW would be 5,200 W. Next divide the total system size in Watts by the power rating of the panels you’d prefer. If we use 400W, that would mean you need 13 solar panels.

How do I calculate how many solar panels I Need?
