You can buy thin-film solar panels in the UK, but as they’re not as common as standard solar panels, you should expect the process of finding an installer to take longer. Here are a few companies that provide thin-film solar panels. Midsummer Energy sells a range of thin-film solar panels, from 70 watts up to 500 watts.
This means that you shouldn’t be getting thin-film solar panels to make a difference to your energy bills, as their output will never match up to what a traditional crystalline silicon solar panel system can produce. Instead, thin-film solar panels are only really suitable for people on the move.
Thin-film photovoltaic (TFPV) cells arean upgraded version of the 1st Gen solar cells, incorporating multiple thin PV layers in the mix instead of the single one in its predecessor. These layers are around 300 times more delicate compared to a standard silicon panel and are also known as a thin-film solar cell.
This is the dominant technology currently used in most solar PV systems. Most thin-film solar cells are classified as second generation, made using thin layers of well-studied materials like amorphous silicon (a-Si), cadmium telluride (CdTe), copper indium gallium selenide (CIGS), or gallium arsenide (GaAs).
In contrast, the manufacture of thin-film solar panels involves coating a base material (known as a substrate) with a thin layer of photovoltaic material, such as amorphous silicon (a-Si), cadmium telluride (CdTe), or copper indium gallium selenide (CIGS). The substrate is usually made from glass, metal or plastic.
How much do thin-film solar panels cost? A 3.5 kilowatt peak (kWp) thin-film solar panel system costs about £3,500, which is around a third of the cost of a traditional solar panel system of the same size.
