Solar Photovoltaic Panels
Photovoltaic (PV) panels produce electricity from sunlight. The electricity produced can be used for domestic or commercial electricity needs or exported to the national grid. This process is managed automatically by an electronic box called an inverter. Although they are still less efficient and more expensive than solar hot water panels, they are a much better way of powering your electrical equipment than buying from the national grid and they will be more cost effective in the long term.
From 1st April 2010, the Government will be introducing an incentive called a Feed In Tariff. This will give producers of renewable electricity such as Solar Photovoltaic a payment for every unit (kWh) of electricity they produce. This means that installation of PV panels will have strong financial benefits as well as reducing both CO2 emissions and our reliance on grid electricty. The table below gives the typical cost, size, savings and earnings that you could expect from a PV installation.
