Mr. Paul Kenny:

To compare like with like, it will be more expensive on a small roof than on a farm. However, if one is clever about the microgeneration subsidy and one only supports the export by a small sum, one will get all of the generation for a small sum and will subsidise only the spill. If one generates 100 units, one only subsidises 20. It is much cheaper than subsidising the 100 units. There is no current plan, even in the climate plan, to subsidise anything.
