Act now and receive the current tariff of 21p and get a great return on your investment. On July 1st 2012 the Feed-in Tariff rate could be reduced to as little as 13.6p.
The Department of Energy and Climate Change (DECC) released a gradual reduction schedule of the Feed-in Tarrif stating that depending on the amount of Solar PV installed in March and April the current tarrif would fall to 13.6p
You may think July is a long way off but a typical Solar PV Install can take up to 3 weeks to prepare and install.
