FAQs about Solar Panels
Solar panels are devices that convert sunlight into electricity. They are made up of photovoltaic (PV) cells that absorb sunlight and generate direct current (DC) electricity. An inverter is used to convert this DC electricity into alternating current (AC) electricity, which is usable in homes and businesses.
This does depend on how much electricity you use, how much you can generate and how much you pay for your electricity. At the moment, we are seeing payback periods being as low as 4 years. As the panels have a guaranteed lifespan of 20 years, you can then get a lot of free electricity for many years to come.
The amount of space required depends on the size of the solar panel system and the efficiency of the panels. A typical solar panel installation will use 6 to 8 solar panels and this will generally take up most of the space on an average roof area. You then need some space inside the house or commercial building for the electrical equipment. This will consist of an inverter, a new meter and various isolators, other switchgear and so on. At least 1 mtr x 1 mtr of free wall space is normally recommended. If you want a battery.
