The panels are interconnected and the electricity fed through to an inverter.
The PV Cells have a life expectancy of more than 25 years and they are virtually maintenance free so you can be assured of getting a good return on your investment. Installing a 1.2 kW array of photovoltaic cells and connecting into the grid is a relatively simple exercise. The finished array looks very neat and in these conditions will be paying its way in no time.
Ok, there it is, the photovoltaic’s are installed on the roof. They are wired into here, this is the inverter. Now that allows us to pump it back into the grid so let’s go see what the electricity meter is doing.
So, this is the old meter. Soon the power company will replace that with a new one so they can read what is going back into the grid but interestingly while we have got the old one here when we are generating enough power you can actually see it going backwards.
