There are several key steps involved in the installation of a home solar energy system. The first is a survey by a professional to ensure that the roof and rafters are in good condition and that the solar PV installation can go ahead safely. This is a standard part of the process and can add to the initial estimate from your installer.
If the survey is good, then scaffolding is erected on the roof to give the installers safe access. The installers will remove some roof tiles, then install mounting brackets on the rafters. These mounts are attached to rails that extend from the rafters to provide support for the panels.
The solar panels themselves are connected to the rails with electrical wires. These wires are then connected to the inverter. The inverter turns the direct current produced by your solar panels into the alternating current that is used by household appliances. Some systems also include a battery bank to store the generated electricity. For Solar Panel Installers Yate, consider https://redbridgeandsons.co.uk/solar-pv-panels/solar-panel-installers-yate
The inverter can also connect to the grid, if you choose to feed power back into your local utility. Once the system has passed all of its inspections, your installer will get in touch with the relevant authorities to arrange the connection to the grid. Your local utility company will install an electric meter that tracks the energy your house uses from the grid and the energy you produce and send back to the grid.
