Solar Electricity Frequently Asked Questions

What are the benefits?

You will be generating your own green electricity – not only will you reduce your electricity bills but you will also help reduce carbon emissions from you home.

PV systems produce no greenhouse gases and each kWp can save approximately 455kg of carbon dioxide emissions per year, adding up to about 11 tonnes over a system’s lifetime. * Source – Energy Saving Trust

If your home produces excess power and your Solar Electricity system is connected to the mains, then electricity can be sold back to the national grid – if your supplier has a scheme which allows this.

Is my home suitable?

Solar works best on buildings with roofs that face south, south east or south west.

Your home may not be suitable if large trees or buildings overshadow the roof (if the roof is in shadow for part of the day, the effectiveness of the system decreases)

Solar panels are not light and your roof must be strong enough to take their weight, especially if the panels are placed on top of existing tiles – our surveyor will assess this for you.

Do I need planning permission?

In some instances, planning permission may be required if you live in a conservation area or listed building. We would always recommend checking with your local planning authority first.

How much maintenance is required?

Solar panels require very little maintenance. All they need is to be cleaned periodically.
