We install a 1.2kw solar panel array on the roof of the garage. They will produce around 8 kwhs of electricity per day on average. The aim is to increase the energy efficiency of the house so that we use less electricity that the solar panels produce. The power from the panels is put through an inverter and put back into the grid. We we connect it it makes the electricity meter turn in reverse as we actually generate more power than we are using in the house.
Solar Panel Array Installation
Photo voltaic cells are an important focus of our retro-fit.
The photo voltaic or PV Cells are destined for the garage roof. There is enough space there to accommodate the 1.2 kW array. Current government rebates apply to the installation of the array but rebates are subject to change so you will need to check if you qualify.
The panels are mounted on aluminium frames. This is vital to ensure that they are set to the correct angle. In this location it’s around 7 degrees. When it is finished we are hoping to generate about 7kwh per day which goes back into the grid. It may even give us some return.
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.
