What is FIT

Basically, with this scheme, you get paid for electricity that you generate with eligible renewable energy systems, like photovoltaic (PV) solar panels.

If there is surplus energy produced by your panels that you don’t use, you can sell it. As well as earning you money, this also encourages energy efficiency in the home or business, as you make more money with the less energy you personally use.

You can get paid and save money under the FIT scheme (similar to the eco boiler scheme) in three ways:

  1. Your energy supplier pays you a set rate per unit of electricity you make, with the ‘generation tariff’,
  2. Your energy supplier will then pay you a little more for every unit you export back to the grid (the ‘export tariff’).
  3. Your electricity bills will decrease or even be eliminated. You only pay for the electricity you use from the grid, i.e. when you haven’t produced enough electricity yourself. If you produce enough to cover your usage as well as a surplus, you’ll make money from your supplier.

Further Benefits of Switching to Solar Energy

As you can see, the government are making the installation of solar panels an even more attractive prospect, to get more people to switch to green energy. Not only are you powering your own home or business with green energy and reducing your carbon footprint, but you could be providing renewable energy for others AND getting paid for it.

There’s never been a better time to contact a green energy solutions company near you, who will be happy to discuss all the benefits of investing in solar panels with you, plus provide you with reliable installation from experts.

Here are some of the other massive benefits of installing solar panels, financial or otherwise:

  • Solar PV panels don’t release any harmful pollutants or carbon dioxide like regular non-renewable energy. The average home solar PV system could save around 1.5 to 2 TONNES of carbon per year – an incredible reduction to your carbon footprint, helping you on your way to becoming carbon neutral.
  • A typical home PV system in London could earn you up to £250 in Feed-In Tariff payments per year, and save you £70 on your electricity bills per year. These figures vary from place to place but show great savings for a family home.
  • It’s worth bearing in mind that larger systems are usually more cost-effective than small systems. The initial cost of solar batteries, panels and installation may be more, but the more energy produced, the more you’ll make and save; therefore the faster it will pay for itself.
  • Of course, alongside all the financial benefits, the main takeaway from switching to green energy is reducing your impact on the environment. It helps towards decreasing our collective dependency on fossil fuels, reduces air and ocean pollution, and makes a small step towards a better world for everyone. If everyone made a conscious effort to move away from fossil fuels, we could dramatically reduce the negative effects on climate change and the environment.

If you are still unsure about all the benefits that a renewable energy system could bring to you, there are solar energy calculators available online (a good one can be found at the Energy Saving Trust website).
