Solar photovoltaics otherwise known as solar pv, absorbs radiation from the sun using photovoltaic cells. Contrary to popular belief pv cells do not need direct sunlight to work – they can still generate electricity on a cloudy overcast day. The pv cells convert the sunlight into electricity, which can be used to run your appliances and lighting.
Everyday light will hit the solar panels on your roof with photons (particles of sunlight). The solar panel converts those photons into electrons of direct current (DC) electricity. The electrons flow out of the solar panel and into your inverter and other safety devices. The inverter converts that DC power into alternating current (AC) power. AC power is the kind of electricity that your television, computer, and toasters use when plugged into the wall.
A generation meter keeps track of the all the electricity your Solar PV system produces. Any electricity that you do not use will go back into the national grid through the meter. At night or on cloudy overcast days, when your system is not producing more than your home needs, you will consume electricity from the grid as normal. Your utility company will pay you for every KW your system produces and they will pay you extra on top for the electricity that goes back to the grid.
Most homes can have solar pv installed on them but some homes are better suited than others. The first condition is that you must own the property that you would like to have the panels installed on. If you have a decent amount of roof space that is preferably south facing then your home may be suitable for solar panels.You can still have a solar pv system installed if your property does not face south however the system will not work to it’s maximum potential. Another thing to check for is shading. It is important that the suns light is not obstructed by other buildings or overhanging branches. Many causes of shade can be remedied by cutting back tree lines and relocating aerials and dishes etc.
The Feed In Tariff (FiT) offers guaranteed payments to homeowners who produce their own energy at home using renewable technologies such as solar photovoltaic (PV) panels.
The FiT was launched in April 2010 to reward households and community groups who install their own electricity-generating ‘microgeneration’ technology with regular and guaranteed index linked payments from the government.
There are three saving elements to the feed in tariff.
There has never been a better time to invest in Solar PV to save substantial money on your bills.
You could then also re-invest in further solutions to save you even more money such as led lighting, solar thermal or an air source heat pump.
