      More like 4m². And yes, they are dirt cheap so they break even after 1.5-2 years and then slash 100 to 150€ off your annual electricity bill. Absolutely worth it.

      Yes. You can get a few hundred watts. It wont be enough to supply 100% of electrical needs, but its enough to make a meaningful difference
