Can I make money from fitting solar panels?

Yes. With the Feed In Tariff, you are paid a fixed amount of 43.3p per kW of solar electricity generated and then used within your home. If for example you are out at work during the day and you export the solar electricity to the grid you get an additional 43.3p per kW. The total amount paid over a year depends on the size of the system and the orientation of the roof. A number of examples can be seen on our case studies page here.

What size system do I need?

Domestic solar power (PV) systems are completely modular and a typical domestic systems range from 1 - 4kWp. The size of your solar panel installation is governed by 3 things; the size of your roof, your budget and G83 limits. For domestic installations the size is limited by G83 regulations meaning a system is not allowed to kick out more than 16A or 3.6KW back to the grid.

If you have the space and budget for a larger system the financial and energy returns get even better. However there a few more rules and regulations to consider. Please contact us to discuss systems over 4kW.

If you would like more information on what size system you require please get in touch and we would be happy to help.

How much roof space do I need?

Each domestic solar power (PV) system is different. One of the team will conduct a detailed site survey to determine the available roof space and the budget you are working with. All shapes and sizes of roof space can be used so don't worry of yours is a bit unusual.

How much is the government grant?

Grants for solar panel installations have all but dried up in recent months as the initial 'pot' has been used up. There are still grants available in some areas, depending on funding available to local councils.

Will I have to change electrical supplier?

Nearly all electrical suppliers will buy back domestic generated solar power (PV) electricity. However some buy at a better rate than others. The Greener Group will advise on the best domestic solar power supplier at the time of purchase.

Do solar systems only work when the sun is out?

The solar panels absorb light to generate energy. So while they work best on long summer days when there is the most light, they still generate energy in winter and only actually require daylight to produce solar electricity.

What is the best place to locate solar panels?

South facing locations are best, then south west and south east. A west facing roof is better than east, whilst north facing is unsuitable as are shaded locations. The optimum angle for the collector is 30 degrees.

Do I need planning permission?

Not normally if you live in England. We always advise that you check with your local planning authority if you live in Wales, Scotland or Northern Ireland or if you live in a listed building or a conservation area. We have also encountered locations where councils have removed permitted planning rights (meaning planning permission is required for solar panel installation) and the customers had no idea! In the event planning permission is required, do not worry, we have successfully gained planning applications for a number of installations, even where the building is in the vicintity of a listed building!

Can solar panels be fitted on to shallow pitch or flat roofs?

Yes, but they will be inclined to achieve the correct pitch. You cannot fit them on asbestos or thatched roofs.

How long does it take to install the systems?

Approximately 2 days subject to the size of the installation.
