How Large Of A Solar Panel System Do I Need

Calculate the size of your solar system.

How large of a solar panel system do i need.

To figure out how to size your solar system take your daily kwh energy requirement and divide it by your peak sun hours to get the kw output. A 5kw solar system may produce enough energy to power your home but you may not have enough roof space for a system of that size. How many solar panels do i need to power my house. How many solar panels do you need for a 2000 sq.

That panel is rated at 100 watts at peak efficiency meaning on a 78 degree cloudless day at solar noon on the equator during the equinox. Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs. Solar panels for households typically come in the standard dimensions of 1 70m x 1 00m that s around 1 7m2 for every panel installed however the wattage output w of the panels will likely vary between 250w and 360w for a more efficient module. Solar shingles are smaller than panels and their wattage is lower as a result.

For example if the amount of power needed is 5 000 watts and each shingle is rated at 50w you need 100. But if you used medium efficiency panels that number lowers to 508 sq ft. For a 10 kw system size using low efficiency panels your system will occupy around 612 sq ft. To get these numbers we used high and low panel production ratios to calculate how many solar panels are needed on average.

To cover that energy need. Then divide the kw output by your panel s efficiency to get the estimated number of solar panels you ll need for your system.
