Duh
Of course this was going to happen.
An audit of solar-power generation from November 2009 to January 2010 found that some panel operators were paid for doing the "impossible" -- producing electricity from sunlight during the night, El Mundo reported today, citing a letter from Secretary of State for Energy Pedro Marin....
Preliminary evidence shows some solar stations may have run diesel-burning generators and sold the output as solar power, which earns several times more than electricity from fossil fuels, El Mundo said, citing unidentified people from the energy industry. The power grid received 4,500 megawatt-hours of power from midnight to 7 a.m. in the months audited, El Mundo said.
Electric current is electric current. However, in a country like Germany, the price that utilities are required to pay for electric current varies based on its source. While electricity from, say, a diesel generator gets 4-5 Euro cents per KwH, ground-based solar gets about 48 Euro cents per KwH. This is a 10x greater price paid solely for absolutely identical power manufactured in a different way. So of course there is going to be fraud as to the current's source.
