Well that explains it a bit, I thought you were talking about 2m² as well.

well, efficiency is only going to get better. so it's only a matter of time until we are at tghat point, or at least very close to it.

and if you think about it, 35m² is not much. I mean, which homeowner doesn't have 35m² of roof to spare ?

the electricity that we put into the grid is supported by the german government, that amounted to over 2.000,00 € in pay-off, way more than what we had to pay for electricity the same year. So it's a good deal, at least under the current circumstances.

OK, thanks, now it makes sense.

This is a pretty darn good idea... kickstarts the deployment of grid-tie systems. As you said, the conversion tech is improving, and there will come a time when solar grid-tie systems reach the level of efficiency needed for self-sufficiency or even net contribution.

the sun already produces sufficient light to provide the whole world with solar energy.



Theoretical Space needed for solar power plants to generate sufficient electric power in order to meet the electricity demand of the World, Europe (EU-25) and Germany respectively. (Data by the German Center of Aerospace (DLR), 2005)

Solar energy is the way forward and the only way to allow all of mankind access to cheap energy. I mean, it is basically unlimited, and conversion efficiency isn't really a factor because of that.
