1. Do I need planning permission?

Solar roof systems fall under permitted development rights so you do not need planning permission, although if you live in an area of 'outstanding natural beauty' or in a listed building you should contact your local council.

2. Does the system need batteries?

No, the systems we sell are connected to the national grid. In the night, when the system is not generating energy, electricity is bought from the utility company in the normal way. Any excess electricity generated during the day, for example when you are at work, is sold back to the utility company.

3. What is the proposed design for the system, in particular roof fixing, layout etc?

We have a range of standard designs and will pick the most appropriate layout for your roof. The fixings will not affect the structural integrity of your roof.

4. What structural checks are undertaken prior to installation?

Once our advisor has made an initial assessment and if you appoint Solar Technology PV Energy as your installer we will send our surveyor to conduct a detail structural survey before any works are conducted.

5. Can I just buy the solar panels and equipment off you and install myself?

Yes, but It is worth pointing out that if you installed a system yourself it would not be covered by our warranty and also, to claim the feed-in tariff the system needs to be installed by an MCS installer.

6. We have a south facing roof, but it can only accommodate 8 panels. Does this mean it’s not really worth having them installed?

Far from it! 8 panels (a 1.560kW system) would save/make you quite a lot of money over 20 years.

7. Can I split the panels over multiple roofs?

Yes, our installer / sales team will be able to give advice on that

8. We get some shadows from trees about 20-30m away. Would this affect the efficiency too much?

It will not matter too much, but it will have an effect. It is hard to state how much without seeing your site.

9. Is electricity produced by the inverter compatible with computers etc?

Yes. It is converted to 240V AC in the same phase as your normal grid power. There will be no discernible difference.

10. What is the best angle to install PV at?

30 to 40 degrees from horizontal is the best for the UK.
