        right, so that’s most likely optimal placement, with peak efficiency being reached for a little while each day as long as the weather is good. if they lie flat, you can lose as much as 90% of that energy, and that’s still with proper maintenance. flat panels also don’t self-clean, so maintenance would be even higher.

        basically, you can probably skip the multiplication altogether.

          It’s not the most optimal. It’s for a 20% panel slightly south of England:

          However, in Michigan, which receives only 1400 kWh/m2/year,[3] annual energy yield drops to 280 kWh for the same panel. At more northerly European latitudes, yields are significantly lower: 175 kWh annual energy yield in southern England under the same conditions

              I have calculated conservatively. The result is the lower bound. With optimal conditions twice the energy could be generated.

                it’s not though, because we’ve already shown that it was overstated by a factor of 10.

                  No, you thought that I had inflated numbers and thus reduced the factor but that reduction is not necessary. There is even another underestimation because the land for the tracks is wider than three meters.

                    i gotta ask, is this a devils advocate thing? because your responses are all so incredibly off that i can’t realistically believe that you believe what you are saying.
