Did a back-of-the-envelope calculation.. these panels look too be about 40x40cm. With solar having a typical peak power of about 200W per m² you'd need about 300 of them for a 10KW peak home solar array (then you'd also need to hook up all the 300 batteries to have power through the night and not live in the US, where houses typically use way more power). Hypothetically of course..
