Tesco has announced that it is extending its ‘Summer Solar Sale’ following the Department of Energy and Climate Change’s decision to maintain the current feed-in tariff (FiT) of 21p until August 1.

The retail giant is urging customers to act quickly before the FiT rate is cut to 16p and the duration of payments drops from 25 to 20 years. Tesco’s Summer Solar campaign forms part of the company’s wider Home Efficiency drive.

Tesco states that the decision to extend the promotion was taken to provide the public greater access to solar and to help “those who may not have benefitted last year.”

Announcing the extension, Adrian Wight of the Tesco Home Efficiency Campaign said:  “We are delighted to be able to extend the 20 percent summer solar promotion as the return on the investment is extremely good but will not be around for long so the message is clear – if you want to reduce your electricity bills, make your home more energy efficient and benefit from feed-in tariff payments over the next 25 years you need to act now.”

Under the offer a 3.93kWp system, which Tesco was selling for £14,499 last November, will now sell at £6,799.
