How to charge for solar panels connected to the grid
For financial benefit. Connecting your solar PV system to the grid allows you to take advantage of the FIT, which gives you a fixed amount of money for each kWh of electricity you generate. On top of these payments for energy generation, you also receive a sum of money for feeding any surplus energy into the grid. By. Your installer should do most of the hard work for you. Once your system is set up, your installation company will supply all of the necessary information. For smaller systems, the installer will generally only need to inform the DNO of your connection within 28 days, providing that your system complies with engineering recommendation G83/1-1 Stage 1. Essentially, this. If you bought your property after 1st October 2008, you should already have one, as the builder or previous owner was legally obliged to provide.
