How to size a solar panel system for my home.

To calculate the size of your solar photovoltaic system take your daily kwh energy requirement and divide by your peak sun hours to get the kw output you 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. Determine how many solar panels you ll need. To cover that energy need.

For a 10 kw system size using low efficiency panels your system will occupy around 612 sq ft. 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. As a guide you ll need 4 x 250w panels or 3 x 330w for every 1kw of your solar system. Then divide the kw output by your panel s efficiency to get the estimated number of solar panels you ll need for your system.

But if you used medium efficiency panels that number lowers to 508 sq ft. Though it is certainly possible to install a solar system and then add more panels later on to. And for highly efficient panels it reaches down to 448 sq ft. In the example above you would need 24 solar panels to account for 80 of your average consumption 29 6 kwh daily usage divided by 1 24 kwh per panel.

For example pairing your electric vehicle with solar panels is a great way to reduce carbon emissions and improve energy efficiency however it should be planned accordingly considering it could potentially double the size of your pv system.
