Frequently asked questions

Solar energy takes advantage of the sun’s rays to generate heat or electricity. It is an infinitely renewable resource and unique for its ability to generate energy in a quiet, clean, and consistent manner.

In layperson terms, photovoltaic cells are comprised of a semiconductor material such as silicon. Added to the silicon are the elements phosphorous and boron which create conductivity within the cell and activate the movement of electrons. The electrons move across the cell when activated by the sunlight’s energy into the electrical circuit hooked up to the solar panel.

Of course this is a relative question. It depends, in part, on how much electricity you use and how efficient the appliances are that you operate. That said expect to generate excess electricity in the summer (when days are long) which can potentially offset the energy you use from the grid in the winter. A combination of energy efficient appliances and light bulbs can help reduce your homes energy bill by over two-thirds.

Solar photovoltaic panels require little or no maintenance – no need to wash or dust. It is, however, important to place panels where they will remain clear of shade and debris. Solar hot water collection arrays don’t need much attention either. It does help to periodically use a window wash brush, biodegradable soap, and water to clean the tubes.

In many cases installing solar panels on domestic land is likely to be considered ‘permitted development’ with no need to apply to the council for planning permission.
