The savings you make once your Solar PV system is installed are likely to increase in time, as the cost of energy increases.

Reduction in cost of solar PV

Huge reductions mean Solar PV install costs are now lower than ever. When the Government introduced the FIT rate at 43.3p, the cost of an average 4kW Solar Photovoltaic System was around £17,000.00. The Feed In Tariff was a massive success and took off in the UK with a bang. In no time at all the UK Government realised they had nearly reached the 2020 carbon reduction target, and therefore lowered the Feed In Tariff rate. As the FIT rate was lowered, the panel manufacturers had to recalculate their costs as to make the Return On Investment worthwhile.

Average cost for a 4kW system now stands between £5.5k – £6.5k with our approved installer. With a lower Feed In Tariff and a lower install cost; the ROI is still very appealing to anyone interested in saving money, making money and generating their own electricity. So as it stands today, the Feed In Tariff is lower, but so are the installation costs. Prices for solar PV have never been lower, and panel manufactures still offer the highest quality products with a high efficiency.

Now is the time to commit to a cleaner and greener future. **

Earning and savings with the FIT Payments (Feed In Tariff)

The Government has an objective to reduce UK carbon emissions by 80% by 2050 which has led to the introduction of Feed in Tariffs (FITs); a scheme that rewards homeowners who generate and use sustainable electricity. Installing Solar PV panels with will mean you’re eligible for a quarterly payment.

Tariffs are paid for 20 years and indexed linked to RPI (Retail Price Index) so the rate will increase with inflation.

You are paid for the electricity you generate, even if you use it yourself, for any extra electricity you export to the grid and of course you’ll also save money on your electricity bill, because you’ll be using your own electricity.

Your energy supplier will make the FIT payments to you at a set rate for each unit of electricity you generate, you will then receive a further payment at current rate from your energy supplier for each unit you don’t use and export back to the grid, as well as making savings on your electricity bills. The large energy suppliers are required by law to provide FIT payments; smaller suppliers are not, but many have opted to offer them anyway.
