Do I need planning permission?
PV roof systems fall under permitted development rights and so do not require planning permission. However if your building is listed or is in an area of outstanding natural beauty, please consult your local council planning department for advice before proceeding with installation.
Will my roof be strong enough?
How long will the installation take?
Do panels need cleaning?
Usually dust and dirt washes off when it rains if the panels are installed at an angle of at least 15 degrees. In extreme cases, dirt may cause a power reduction of about 10%.
How long do PV panels last?
Our PV panels have a product warranty of 10 years, expected lifetime of up to 40 years, performance of 90% for 10 years and 80% for 20 years.

Do the PV panels need direct sunlight to work?
What happens if there is a power cut?
Can I buy a system and install it myself?
