It has been over a week since our solar panels were installed, 48 100 watt panels in all. The installation used all the available north facing roof space with the remaining panels being installed on the western side of the house.
Why did we decide to purchase the solar panels, guess there are lots of reasons, the main is that we are environmentally aware.
A kilowatt of electricity generated on our roof means that a kilowatt of power can be used at our house, where as a kilowatt of power produce at the power station means that a lesser amount of power reaches our house.
Currently in South Australia the Government is buying back electricity from homes that have solar panels installed at a higher rate than what the electricity is sold for. My electricity provider with the Government incentive pays me 50 cents per kilowatt generated which is sent out to the grid. I pay approximately 20 cents per kilowatt that I use from my provider.
Adelaide is an ideal spot for having solar panels, it has a low 87 days a year that it rains. At the time of writing this blog it is mid summer and the panels are generating more electricity due to the longer and clearer days. Currently more than 55% of the electricity generated is going back on to the grid and earning 50 cents per kilowatt. The size of our system means that we may never need to pay another power bill, and hopefully we may be refunded from the electricity service provider.
Solar panels have a guarantee of 20 years, based on that many years of use our outlay and the anticipated daily kilowatt generation means that we have prepaid for our electricity consumption. We paid about 29k for the system, and we anticipate that over 200,000 kilowatts of power will be generated over the next 20 years, based on those 2 figures we are paying 14.5 cents per kilowatt generated. Well below the current market rate of electricity and our rate will not be influenced by any price increases.
