PV Roof fitting


Solar PV panels are mainly comprised of Silicon - one of the most abundant materials on our planet!

General FAQ's

Do Solar PV Panels need direct sunlight to work?

The panels work from daylight and not direct sunlight, although more power will be produced on a sunnier day.

Will they work at night?

During the night energy is drawn from the grid as PV panels do not work in the dark.

Does shade effect the PV panels?

Shading is a critical factor to consider as minor shading can result in a significant loss of energy, however this can sometimes be avoided by splitting the array into two sections.

What happens during a power cut?

The PV systems that we supply are entirely grid connected, in the event of a power cut the system is automatically switched off as a safety measure.


Installation FAQ's

Will my roof be strong enough?

Most roofs are strong enough to support a PV installation. Our trained installation team will perform a full survey to ensure no reinforcement is required.

How much space do I need?

The smallest kit we offer is 1.44kW peak power and occupies roughly 10 square metres of roof space.

Do I need planning permission?

Falling under permitted development rights PV systems do not require planning permission. However, if your building is listed or in an area of natural beauty you should consult your local council prior to installation.

Do I need to inform my current electricity supplier?

For any system less than 4kW your installer will inform them once the PV installation is complete, for a larger system permission needs to be gained in advance.

How long will it take to install the system?

For a domestic installation it normally takes around 2-3 days.

What are the optimal conditions for a PV system?

The panels work best when installed on a south facing roof at an angle of 30-40 degrees. They can work at different angles on west or east facing roofs but will not produce as much power. A site survey will determine the best option for you.

Does the system need batteries?

No. The PV systems that we supply are connected to the grid and any excess generated is fed back.

Can I install the system myself?

Our PV systems must be installed by an MCS Accredited installer, if not it won't be covered by our warranty or be eligible for the feed-in tariff. All A&D Alternative Energy installers are MCS accredited.


Cost, benefits and the feed-in tariff FAQ's

How much will it cost me?

It is not possible to provide an exact figure as it depends on several factors. If you'd like more information please contact our helpful team and ask for a free no-obligation quote.

How much energy will my Solar PV system generate?

This depends on a few different factors; the total size of your array, latitude, angle of the panels, shading. Again, as every system is different we can't provide an exact figure, if you'd like more of an idea please contact us.

What is the Feed-in tariff?

It's a financial incentive backed by the government and paid by your energy supplier to encourage you to create your own clean energy. Every kWh you generate earns a tax free income, and anything not used can be sold back to the grid. For more information on the Feed-in tariff scheme please visit http://www.energysavingtrust.org
