Need to know as to how to calculate the number of 330 w or 150 w solar panels.

In order to calculate the below data we averaged annual kwh production in the top 12 solar states and assumed standard 250 watt panels in order to calculate how many panels you would need. In other words you will calculate the solar energy system s inputs. The first way to achieve your energy goal is to conserve electric power by reducing appliance use and using efficient appliances. Divide the watts you need to produce per hour by the rating of the panels you want to purchase and round up.

Other factors such as shade location available panel space and seasonal use need to be taken into account. How many solar panels do i need for 1 000 kwh per month.
