Solar thermal heating for hot water is clearly by far the most popular form of domestic renewable energy, proving that it works technically and economically.
That is clear from the Low Carbon Buildings Programme (LCBP)'s project successes: since it launched in April 2006 the LCBP has directly funded 2175 installations on homes, including 1467 (over two thirds) solar thermal heating systems, 313 (14%) solar PV projects and 242 (11%) mini-turbines.
In other words solar water heating is six times more popular than micro-wind. Deservedly.
The application process for the grants has been streamlined and it reopened to bids for the remaining £11.9m of grant money two days ago.
There's now no monthly cap, a £2,500 maximum limit on grants per household, a requirement for advance planning permission required and a re-designed form.
No doubt this will run out in a few weeks - then what?
The Low Carbon Kid says: if solar water heating is so popular why has it been left out of the Energy White Paper?
