Corrected misplaced decimals for H2 mass and volume conversions.

Jun 9, 2018 at 19:47 comment added Chris H @Joshua but then they'd be selling (shares in) the solar panel, not claiming they can use a standard one. Maximum power point tracking is well-established for the output side and is probably required to get that 200W in practice
Jun 9, 2018 at 14:32 comment added Joshua One more thing to do. What if they found some dumb way to get the solar panel up to carnot efficiency? Hint: it's still too low.
Jun 9, 2018 at 12:08 comment added juhist @Kyle You are right, a 200W solar panel produces 200W of electricity at direct sunlight. The input energy of said direct sunlight is about 1000 W - 1300 W depending on the efficiency of the panel. This is how solar panels are rated, so yes, the solar panel output rating already takes into account the efficiency of the panel.
Jun 9, 2018 at 6:33 comment added Kyle Doesn't the solar panel output rating already account for the efficiency of the panel? Not that it really changes the conclusion; as far as I can tell the average American household uses about 1.2 kW of power (~10500 kWh/year), so powering a house with a single 200 W panel is clearly ridiculous.
Jun 9, 2018 at 4:10 comment added ElderBug Your quora source is full of mistakes. 0.003kg of H2 per hour is correct, but 0.003kg is 3 grams, not 0.3. And 3 grams of hydrogen is 33 Liters (33000cc), not 33cc. So 20% of 200W would generate over 8000cc per hour. Not that it changes anything, the whole claim is insane anyway.
