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.
The Planning Considerations of Solar Photovoltaic
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.
Reasons to Use Solar Photovoltaic
There are several good reasons to use solar PV cells. One important benefit is the money saved on electrical bills. Another important benefit is the reduction in carbon emissions thanks to using clean energy. Solar photovoltaic cells cut around 1.2 tonnes of carbon dioxide emissions every year. Since the user generates the electricity directly from the sun, they are not dependent on the national grid, making them less prone to power cuts. Although solar power is effective in its own right, solar panels are highly appropriate for remote locations where the grid has no coverage (such as remote farms or 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.
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.
