Solar Electricity Panels

Solar Electricity (or PhotoVoltaic) panels generate electricity for domestic and commercial use. Panels come in a variety of different shapes and sizes but one question that people have to decide is whether to have the panels mounted on the roof or in the roof.

On Roof Solar Panels

The easier way of retrofitting solar panels is to mount them on top of the existing roof covering. this means that the existing tiles remain in place and the panels sits directly on top. The panels are fixed to the roof joists via special brackets.

Roof integrated Panels (In Roof)

As an alternative to on roof panels the existing tiles can be removed and the panel can be fitted into the roof structure. This leaves the panels almost flush with the existing tiles.

When making a decision as to which is best there are a number of factors to consider. On roof solar panels are easier and quicker to fit. Hence the installation costs are less. However, on roof panels will add additional loading to the roof structure.

Roof integrated panels require the existing roof covering to be removed, this may raise questions with the condition of the felt and battens beneath the tiles, if it is poor it will need rectifying. In roof panels also require expensive flashing sets to make the roof water tight. However, in roof panels aesthetically look better than on roof systems.

Of course if you have a house that has not yet had the roof fitted (new build or new extension) then roof integrated panels are almost certainly the way to go. You will also save some money as less tiles will need to purchased.
