Installation of a typical solar panel system

Our Surveyor will do the following:

Measure your roof’s orientation, inclination and shade coverage
Give you an estimate of the PV system output based on the above geographical factors

Give an estimate of the money you are likely to earn/save
assess your roof’s ability to bear the weight of a PV installation
Check your property’s electrical specifications (fuse box, metering etc)
Ascertain your current energy consumption/needs (based in part on your property’s EPC rating if you have one)

The PV installation itself will involve the following steps:

Put up scaffolding for roof access – this may not be necessary if your property has only one storey
Attach roof hooks to rafters – roof tiles/slates will need to be removed in order to screw the hooks for the frame into your roof rafters. The tiles/slates will be replaced once this is complete,
Fix frame to hooks – the rails that comprise the mounting frame are attached to the roof hooks and screwed together
Mount PV panels onto frame – the panels containing photovoltaic cells are mounted onto the roof frame with the use of clamps
Connect panels to inverter – the solar panels DC output is wired to the inverter which then converts the electricity into AC for use by your property’s electrical appliances or for export to the grid. The DC cabling can either be placed underneath roof tiles and wired to an inverter within your property or mounted externally.
Electrical wiring – the DC output from the roof array is wired to the inverter, and the AC output from the inverter is connected to your property’s electricity supply and the electricity grid. Other electrical components such as AC & DC isolators are installed for safety, and an Ofgem-approved generation meter will be placed after the inverter.  You may have also ordered other items such as batteries for power storage and a smart energy system such as an eddi eco-smart energy diverter

Final checks – Our installer will perform final electrical safety and performance checks before commissioning the system, and provide you with the necessary documentation (manuals, warranties, maintenance information)
