Sun’s Light Powers Solar PV Panels

Solar 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.

The Planning Considerations of Solar Photovoltaic

Solar Photovoltaic panels can be installed into or on top of the roof or along an external wall of the property. Before buying a solar PV system, it is important to ensure that the user checks against the statutes of local area. In England, roof mounted solar PV cells as well as standalone cells can be installed into most homes, but there are certain criteria they must meet. Latest legislations allows for solar panels of up to 100mm in depth to be laid upon a tilted roof without the need for a planning permission. In Northern Ireland, Scotland and Wales, the local authorities are still working on the legislation regarding solar panels, so the local planning authorities must be consulted before any cells can be installed.

Should You 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).

Solar Photovoltaic Installation:

The best way to install solar photovoltaic panels is to hire a professional installation crew. Professional solar PV cell installers should be certified by the Low Carbon Buildings Programme. It is important to note that there are good reasons one should not attempt to do the installation as a DIY project. Solar PV cells tend to be very heavy and, for roof installations, involve a support system that must be constructed and attached before any solar photovoltaic cell can be mounted. The installer will know the local electrical codes and safety regulations and will make sure that the solar photovoltaic grid or standalone units are code compliant.

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.
