Two panels. Same wattage. Not even close to the same savings. ⚡
Most people shop for solar by watts alone — but that number only tells you the lab performance, not what you'll actually get on your roof. Efficiency is the number that actually predicts your bill.
SunPower panels sit at the top of that scale, up to 24.7% efficiency with our back-contact tech — which is a big part of why the math works out better long-term, not just on day one.
Comparing quotes? Ask about efficiency, not just watts. 🔋
