How Many Solar Panels Do I Need? The 2026 Sizing Formula

Ask three installers what size system you need and you'll get three different answers — usually before anyone has looked at your electricity bill. That's backwards. Your bill already contains everything needed to work out the right system size, and the math takes about two minutes. Get it wrong in one direction and you're still importing expensive units from the grid. Get it wrong in the other and you've paid for panels that will never earn back. Here's how to size it properly, with a worked example. Read your bill, find your daily units, and translate them into the right number of panels and inverter size — the 2026 way to avoid over- or under-buying.
