Solar PV panels have been around for many years. Advancement in technology efficient panels and lower production costs.
Solar PV panels work by emitting light into the solar panels cells. Naturally, the more light that hits a panel, the more power it will generate. Due to the angle required for solar panels to work effectively, they are prone to natural external elements such as bird droppings, general dust and dirt and in Wales the unavoidable pollution in the air in cities and in the countryside. This dirt dust and pollution reduce the amount of light hitting the panel and reduces its efficiency and output.
Projected energy figures claimed by solar panel manufacturers and installers are based on the optimum performance of clean solar panels, the build-up of dirt can adversely affect the panel’s ability to meet those projections. Therefore it is important to clean solar panels in order to ensure maximum efficiency, it will also protect and maintain your investment.
Clean efficient solar panels will also assist in maximising your return on the government feed-in tariff.
