Solar Panel Electricity Systems

Produce cheap and clean electricity from sunlight and GET PAID

Electricity prices have increased by roughly 7% every year for more than a decade. The demand for electricity has also grown substantially over the past few years. The residential sector is largely responsible for this increase. Solar panel systems can be designed so that a household’s electricity demand is wholly or partly met. Once your Solar panel system is installed and paid for. The electricity it generates is produced at a constant cost.

Solar panel electricity systems generate electricity by capturing the sun’s energy with photovoltaic cells; the cells convert the sunlight in to electricity. These cells don’t need direct sunlight to produce electricity; so they can still work on cloudy days and produce some electricity.

One of the significant benefits of the solar photovoltaic system (PV) is that, it doesn’t emit any green house gases. A typical home solar system could save over a tonne of carbon dioxide per year that’s more than 30 tonnes over its lifetime.

Also PV, in addition to it being a clean source of energy, could provide some financial benefits for households or businesses that have PV system in their roofs. First it helps to cut your electricity bills, as generating electricity from sunlight is free. So once you’ve paid for the initial installation your electricity, the cost will be reduced.

Secondly, you will get paid for the electricity you generate by the government’s Feed in Tariff scheme (FIT). You will get money for the electricity you produce even if you use it from your energy supplier. Additionally you can sell electricity back to the grid, if your system is generating more electricity than you require or when you can’t consume it, so you can sell the surplus back to the grid.  However, you might still need to buy a small amount of electricity from your supplier if the sun doesn’t shine however, this will be much less electricity than you currently buy.


Costs and Savings

The average size of domestic solar PV system is 4KWP and it costs average between £ 6,000 and £7.400 (including VAT at 5%). Also, PV panels are all around the same price per KWP, but PV tiles cost much more than a typical system made up of panels.

However, the larger systems are usually more cost-effective than smaller systems (up to 4kWp).

If your PV system (4kwp) is eligible for feed in tariffs, it could generate annual savings and income of around £750. It also will save nearly two tonnes of carbon dioxide per year. Therefore, by installing the PV system on your roof, you could combat climate change and also, reduce your energy bills substantially.


Maintenance of solar PV is easy, as it needs a little maintenance. You’ll only need to keep panels relatively clean and make sure trees don’t begin to overshadow them. In the UK panels that are tilted at 15° or more have the additional benefit of being cleaned by rainfall to ensure optimal performance.
