1.8gw of Midsize German Solar Installations due to Feed-in Tariff
The under 10 KW systems accounted for the least growth. Since most German homes probably need 4 to 8 KW systems just to supply their own needs, because of their insolation and mod cons , it would appear that the financial incentive of the Feed-in Tariff amount to be earned on a much smaller excess is lacking. The potential earnings are not enough to overcome the inertia. Feed-in Tariffs have driven Spain, Germany and Italy to world leadership in solar (Italy’s solar is growing at 3 times the pace of the USA using Feed-in Tariffs) but what this graph graphically illustrates is that the earnings have to be worth it.
