Here is the control box installed in our garage.
The reading on this day was better with the sun shining. Here is a close-up of the panels on the day of installation.
My husband Max is now going to add some technical details so he can direct people to my blog if they want information.
The system is a 1kw Grid Interactive Solar Power Generator. This means that it does not store energy in batteries but sends any power we are unable to use at the time into the Power Grid. As you can see from the photo there is an array of six solar panels on the roof. They are connected in series and can generate up to 225 volts at 5 amps DC. The voltage from the panels is fed into a Fronius Grid Interactive Inverter which converts the DC voltage into 240 volts AC and inserts it into the electrical switchboard where it is used by our appliances or lights and sends any extra power into the Western Power Electricity Grid. We get paid for the power we generate and send to the Grid as it is considered "Green Power" and we also have been issued with 21 RECs (Renewable Energy Certificates). The system we purchased is upgradable to a 2kw system by the simple addition of 6 more solar panels. The Grid Interactive Inverter is a Fronius I20 made in Austria and the solar panels are made by Nesl Solartech of China type DJM-170D. The system was supplied by Renewable Logic of Bayswater after we saw the special deal that was being offered when we attended the 2008 Perth Sun Fair at the University of Western Australia.
