Swiss startup Sun-ways is planning to build a 18 kW pilot PV system between the racks of a 100-m linear section of a railway line in the Swiss canton of Neuchâtel.
The problem is that we don’t have enough demand shaping to shift night time loads to day time, and we don’t have enough storage to shift production to overnight. The result is that daytime generation is regularly going into negative rates (you have to pay to put power on the grid, which melts the returns on your investment into solar.
As far as problems go, it’s a good one to have, as it will eventually result in lower prices for daytime generation.
Isn’t A/C a huge power consumer though? And because most lights are led now, except for northern countries the day time would be higher energy use right?
Because it is not cost effective. Simple as that.
