Solar PV Panels are Getting the Right Exposure
Posted by: Tal Potishman / Category: Home Based BusinessSolar Photovoltaic cells, also known as Solar PV, are silicon wafer based panels that absorb energy from the sun and then transfer that energy to your home. When photons of light hit the silicon wafer, they tip them of their chemical balance, creating a movement of protons and electrons in opposite directions, thus generating an electrical current. Solar PV cells are already used in some common appliances such as watches and calculators. Naturally, the domestic or commercial panels come in larger sizes to provide sufficient output. Over the years, some solar photovoltaic cells have been used successfully to generate electricity for very large buildings and other installations including the National Grid.
Solar Photovoltaic and Planning Issues
One can install solar photovoltaic panels on the roof of their home as well as along one of the outer walls or as standalone units. Before setting off on the installation process, it is essential to check with the local authority regarding planning restrictions. Most local authorities in England allow solar PV panels to be installed on residential roofs and as standalone cells as long as certain criteria are met (mainly that the panels are not attached onto listed buildings or within conservation zones). Wales, Scotland and Northern Ireland, however, are still working out their local legislation. For residents of these areas it is therefore advisable to consult the local planning authorities before installing the solar systems.
Should You Use Solar Photovoltaic?
There are several important benefits to having solar PV cells in your home. The most obvious benefit is the ongoing savings on the electrical utility bills. In addition to saving money, the user will be lowering their carbon footprint as solar PV emit virtually no carbon dioxide and cut around 1.2 million tonnes of carbon dioxide emissions every year. An indirect benefit is the fact that the user will no longer be tied to the National Grid which means that they do not have to worry about power cuts or increases in the cost of electricity. Solar power makes a strong economic case for properties in remote areas where there is no coverage by the National Grid (e.g. remote farms, research facilities).
How is Solar Photovoltaic Cell Installed?
Solar photovoltaic cells need to be installed by a professional installation crew. Professional installers must be certified by the Low Carbon Buildings Programme. It is not recommended to try and install the solar panel cells unless you are fully trained and qualified. The cells are typically very heavy and they have to be attached to a separate support system that must be constructed and attached carefully to the roof. A professional installer will understand the local electrical and safety codes and can ensure that the solar PV units are meeting the requirements of the code.
With the increasing public awareness to global warming and climate change, there is substantially more focus placed on finding energy generation options that are not reliant upon fossil fuels. Of the alternative energy options currently available (wave, wind, hydrogen, solar, nuclear), solar power is considered to be the most cost effective and with solar panels dropping in price due to competition, this technology is likely to become ever more popular.
