1500 watts solar panels

How many solar panels does it take to run a 1500 watt heater?

 

In short, you need 6 solar panels to run your heater.

Explanation:

You didn’t mention the usage hours, how many hours you run the heater.

let’s suppose you are using it for 3 hours/day.

first of all, convert the watts into energy by simply multiplying 1500*3= 4500 watt-hours

secondly, divide the total energy by total sunshine hours (sunshine hours are the hours in which the sun give us energy)

let’s suppose in sunshine hours in your area is 8.

4500/8=562.5.

Now, here comes the deal, if you want to put 100watt panel or it’s up to you, you can use a 200wp panel or maybe a high power panel.

let’s suppose you are using 100 wp panels.

562.5/100= almost 6 panels you need to run a 1500 watt heater. In your case, you can change the values as per your current location and usage.
