Solar Photovoltaic Cells Generate Electricity from Sun Light
Solar Photovoltaic cells (Solar PV) are effectively panels that absorb the sun’s light (which is actually made of many tiny units of energy) and convert it via a sophisticated system of silicon wafers into an electrical current that can then be used to power up your home, office or electrical appliances directly. Although not yet highly visible in the UK domestic market, solar PV panels are already very common in calculators and watches (albeit in a much smaller size). The larger solar panels are getting increasingly more efficient and are now used to generate power for private homes, large office buildings and other commercial installations.
Solar Photovoltaic Planning and Regulatory Issues
Solar photovoltaic panels can be installed on the roof, along a wall of the property or as standalone systems. Before buying and installing the panels, however, it is essential to make sure the user understands the installation regulations in the local area. Most domestic installations in England have been cleared for solar PV panel systems and English homeowners can also install the panels as standalone systems, so long as they meet certain criteria (namely avoiding conservation areas or listed buildings). In Scotland, Wales or Northern Ireland, the local governments are still working out the relevant laws. In most cases it is wise to check with your local authority before commissioning the installation of the solar cells.
Why Use Solar Photovoltaics?
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 to Install Solar Photovoltaic
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.
As time marches on, the world becomes more determined to find alternatives for electricity that are not reliant upon fossil fuel. Of the various alternative energy options (solar, wind, wave, hydrogen, nuclear), solar power is considered to be one of the most viable. Every day, domestic panels become more affordable and more popular, helping with the general battle with climate change and global warming.
