How many solar panels do I need?

Probably more than 10 and fewer than 40. We know that’s quite a range, but with solar, there’s really no one-size-fits-all solution: the number of panels you should install depends on how much sun hits your property, your energy needs, and the amount of space you have available for the installation. Most people install a system large enough to generate as much of their electricity needs as possible (that’s how you’ll save the most money!)
