We Offer more and more solar energy is becoming part of everyday life and as you would expect, Dyson Energy Services has been proud to be at the forefront of developing possibly the finest photovoltaic panels to store, convert and deliver the sun’s power as clean and super-efficient electrical energy.
The Photovoltaic (PV) panels convert the sun’s natural light into electrical power using a thin layer of semi-conducting material, usually silicone, encased between a sheet of glass and a polymer resin. When exposed to the daylight (not necessarily full sunshine) the electrons in the semi-conducting material become energised and create a Direct electrical current (DC). This current in turn is sent through an inverter to convert the Direct Current into an Alternating Current (AC) – the type needed to power our lights, televisions, computers – and toasters
Solar PV is a technology that uses the power of the sun to create electricity.
Solar Thermal is a technology that uses the power of the sun to heat water. OK…so what’s the
difference? Well, the only difference is the apparatus used to collect the energy.
We now know how a PV unit works, but a Thermal unit works differently whereby a solar thermal collector (flat plate panels or evacuated tube panels) is installed on the roof of your house.
Inside the collector a non-toxic freeze proof solar fluid is heated by the sun then pumped through a pipe coiling inside the hot water tank, which heats up the water in the tank. Hot water is then available for you to use in the house and the solar fluid is then pumped back up to the collector, where it is once again heated by the sun. Simples!
It is photons in natural daylight that are converted by solar panel cells to produce the energy. Heat has no effect on the production of electricity. True, it works more efficiently if the light is unobstructed, but it doesn’t need full-on sunshine to produce the energy your home needs – and the savings your budget will appreciate.
Over the course of a year, a solar photovoltaic system will save you money by reducing electricity bills, and could earn at least 14.9p for every unit of electricity generated (14.9p rate applies to systems of less than 4kWpk. Over a 20-year period this can amount to a massive return on investment. For example, a typical residential house with a 3.54kWp solar PV system over a 20-year period could generate around £20,257.74 of income (tax-free and RPI-linked).
