It's about time we all started to take responsibility for the impact we have on our surroundings and our environment. Below you can find answers to some of the common questions people have regarding Photovoltaic Systems.

Q. What Is Photovoltaics (Solar Panels), or "PV"?

A. Photovoltaics is a method of generating electrical power by converting solar radiation into direct current (DC) electricity. Solar PV panels have been designed to be attached to roof/walls and are usually made from either monocrystalline silicon, polycrystalline silicon or cadmium telluride.

Q. How Can We Produce Electricity From The Sun?

A. Photovoltaics works by converting sunlight radiation to stored electricity, this process is known as the "photoelectric effect". The photoelectric effect refers to the emission, or ejection of electrons from the surface of a metal in response to light.

Q. How Does It Work?

A huge amount of potential energy is produced every year, this energy falls from the sun to the earth and can be used to power electrical items in our homes and offices. The sunlight falls from the sun on to the panels which in turn creates DC electricity this energy is then inverted into AC electricity. 

Q. How Much Will It Cost?

A. Every installation is different, it all depends on the size of the roof space available. Please click the link below to request a free estimate.

Q. How Much Energy Does The Average Home Need?

This all depends on the consumer, to assess your current usage please contact your electricity supplier and ask them for your average yearly usage. This is by far the best way to size up your usage however you can also add up the units used on your last 3 electricity bills. 

Q. What If The Sun Isn't Shining?

A common misconception of PV panels is that without sun no electricity will be produced. This however is not true, even on cloudy days your PV system will still be producing electricity.

Q. Can I Run Out Of Electricity?

A. No!, if your solar system is not creating enough electricity for your needs it will allow energy from the national grid into your home. This will most likely happen on winter days and at night time.

Q. What If I'm Creating More Electricity Than I Need?

A. One of the main benefits of Solar PV systems is that when too much electricity is produced it is exported to the national grid. You will then of course be paid for it. Please click here to read more information on FIT (Feed-in Tariffs).

Q. How Long Will My Solar Panels Last?

A. A well designed system from Ellwood Electrical will last in excess of the 20 year manufacturer's warranty. The predicted life of a solar PV panel is around 30 years.

Q. Do I Need Planning Permission?

A. In most cases planning permission for domestic home owners is not required, however if your home is a listed building or in a conservation area planning permission will be required.
