Question

To ask the Secretary of State for Energy and Climate Change, if her Department will take steps to incentivise house builders to build homes facing south to make solar panels as efficient as possible.

Installation of domestic solar PV is supported through the Feed-In-Tariff scheme which provides greater incentive to more efficiently deployed panels as the amount of income received depends on the amount of electricity generated. Advice on generation based on orientation, pitch, etc. is given in the Microgeneration Certification Scheme Guide to the Installation of Photovoltaic Systems:
