The 'on roof' method of installing solar panels requires the removal of tiles only in the locations where the roof brackets will be fitted. The roof brackets are fixed to the rafters and the removed tiles are then re-laid over the brackets, so they are flush and not compromising the wind and water resistance of the roof itself.
Aluminium rails are bolted to the bracket tongues that can be seen in between the tiles. The solar panels are then clamped onto the rails so the panels stand off the roof by around 50mm so the panels look like they sit “on” the roof, hence 'on roof'!
The solar panels are connected to an inverter (converts DC electricity form the solar panels to AC) and from there a single AC cable runs to your fuse box / consumer unit via isolator switches and a generation meter.
The advantages of 'on roof' solar systems
On roof solar is still by far the most popular and economical method of fitting solar panels and has a number of advantages:
1. Quickly fitted to a ready built property (takes about 1 day)
2. The panels are easily accessed and exchanged in case of breakage
3. The weather resistance of the roof will not be compromised.
4. Low cost and fast return on investment
5. The completed system can be electric vehicle ready, if requested
Typical costs for a 2.7kw On Roof solar system including design, materials, installation, scaffolding, commissioning and certification is £3000 inc 5% VAT
