In the four months August-November 2012, the PV installation generated 13,644KWh of electricity. These four months on average contribute 29.6% of annual output. Extrapolated to a full year, this suggests an output of 46,106KWh. However, our budget was based on a predicted output of 40,117 KWh. a year. So, the system is performing nearly 15% better than predicted.
