There are lots of good reasons to use solar panels. You will be:
• reducing your dependence on expensive grid energy
• helping to reduce the production of carbon dioxide and other greenhouse gases
• saving and even earning money
Photovoltaics (often abbreviated as PV) is a simple and elegant method of harnessing the sun's energy.
Solar panel electricity systems, also known as solar photovoltaics (PV), capture the sun's energy using photovoltaic cells. These cells don't need direct sunlight to work – they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting.
A kWp is the kilowatt ‘peak’ of a system. This is a standardised test for panels across all manufacturers to ensure that the values listed are capable of comparison.
When the solar PV panels are working they will over an hour convert the suns irradiance into energy, which is measured in kilowatt hours (kWh). A 3kWp PV system which is working at its maximum capacity (kWp) for one hour will produce 3kWh.
Solar PV needs little maintenance – you'll just need to keep the panels relatively clean and make sure trees don't begin to overshadow them.
Solar inverters, also called grid-tied inverters, convert the direct current (DC) electricity produced by your solar PV panels to alternating current (AC) electricity that can be used in your home and exported back to the grid. Solar invertors also:
• ensure compliance with regulations about feeding electricity into the grid, for example by immediately disconnecting if there
is a power cut
• maximise electricity production by constantly varying its resistance (load)
Panels have a performance guarantee of 25 years and could even last longer. Inverters have complex electronics and we provide for replacement of inverters every 10 years or so as technology improves these get better and cheaper. Batteries can last anywhere between 5 and 10 years depending on how the system is configured. As a rule of thumb, the more electricity used during the daytime the longer the batteries will last.
