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. 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 330W for a more efficient module.
As a guide, you’ll need 4 x 250W panels, or 3 x 330W for every 1kW of your solar system. If you’re considering a 5kW system, that’s between 15 and 20 solar panels that will require anywhere between 25.5 – 34m2 of roof space.
