How to size a solar panel system for my home.

Determine how many solar panels you ll need. Though it is certainly possible to install a solar system and then add more panels later on to. 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. 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.

And for highly efficient panels it reaches down to 448 sq ft. Then divide the kw output by your panel s efficiency to get the total number of solar panels for your system. But if you used medium efficiency panels that number lowers to 508 sq ft. However the wattage output w of the panels will likely vary between 250w and 360w for a more efficient module.

One solar panel produces about 1 24 kwh per day. For a 10 kw system size using low efficiency panels your system will occupy around 612 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. 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.

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.
