Solar photovoltaic (PV) panels can be used to power your business, they are a method of generating electric power using solar cells to convert energy from the sun, solar radiation, into electricity. The photovoltaic effect refers to photons of light knocking electrons into a higher state of energy to create electricity. In the UK, the number of hours per annum of solar radiation typically range between 1,000 hours in Cornwall to 800 hours in the Scottish Highlands. With these levels of solar radiation and the Government Subsidies, building owners can fund the installation with cash or conventional borrowing or we can fund the installation through investors. In the case of an investor funded scheme, the building owner is paid a percentage of the Feed in Tariff (FiT) payment as rent and has the benefit of the electricity generated from the scheme for no cost, for 20 years.
We conduct desktop feasibility studies in the first instance to provide indicative illustrations of the benefits, subject to site survey if a project looks possible.
Typically, an array is incorporated into the roof or walls of a building and roof tiles with integrated PV cells can now be purchased. Arrays can also be retrofitted into existing buildings; in this case they are usually fitted on top of the existing roof structure. Alternatively, an array can be located separately from the building but connected by cable to supply power for the building. The following video shows a typical installation on the roof of a distribution warehouse, the impact in terms of carbon emissions reduction, financial and reputational benefits are considerable and will increase over time as will electricity prices from conventional suppliers.
