Different solar panels turn the same amount of sunlight into different amounts of electricity. These are the most efficient solar panels for rooftop solar.

    kind of interesting comparison. I have a 9.8kWp system, and it consists of 405 or 410W panels. I paid approx 1000 euros per kWp, installed.

    I have an electric car and a 24U server rack, and didn’t see an electricity bill whole summer even though we had the 20 year old AC running pretty high all the time.

      Yeah where conditions allow, residential solar is a great deal, and getting better all the time as power costs keep rising. When we installed our system the math came out that it would pay for itself in just over 5 years. All gravy from there.

    It’s awesome that they’re up to 22%. My whole childhood I had the 2-5% number in my head based on earlier panels. This is a real improvement.

    I wonder if that 22% of energy being transformed into electricity has a secondary benefit of NOT being transformed into heat? If so, solar wins coming and going.
