6 2 kwh x 1000 convert to watts 6200 watts solar panel required. Follow along to calculate the amount of solar panels your specific home will need. Yet you can also find panels of 150 160 or 175 watts. Is 5kw 5000 watts so you can use that as a benchmark if you re unclear on what your power needs will be.

The average size of solar panels used in a rooftop solar installation is approximately 65 inches by 39 inches or 5 4 feet by 3 25 feet. The average system size in the u s. With a large usable roof area perhaps you can sacrifice some efficiency and buy more larger panels at a lower cost per panel to get to your target energy output. 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.

But if your usable roof area is limited or if it s partially shaded. If the most standard size solar panels are 17 5 square feet and you have about 385 square feet of roof to install solar panels that will maximize the sunlight consumption you can fit about 22 panels on your roof.

In addition to physical size people often ask us how much solar panels weigh. 33 kwh 6 1 sun hours x 1 15 efficiency factor 6 2 kw dc solar system size required using the example above with a 6 2 kw dc system you can multiply this number by 1 000 to confirm that you need 6 200 watts of solar panels. 50 watt 100 watt and 160 watt.
