Solar Generation in Perth

In March, with the June 30, 2011 deadline for maximizing the REBS rebate looming, and with Retravision coming on board to sell solar system’s (no, I was not foolish enough to buy from Unleash Solar or any of the other random solar companies that sprung up), I finally bit the bullet and purchased a 1.5kW solar electricity generation system for AU$3000. I would have loved to get a larger system, but I was quoted $22,000 for a 5kW system, and even a 3kW system would have costs $8,000, which demonstrates the very odd scaling in place at the time due to the government’s 5x REBS scheme.

This page graphs the results of my systems generation. Note that my system is 1.5kW, and is almost perfectly situated on a north facing, nicely angled, unobstructed roof, so it is probably close to optimum for a stationary system. The graph shows units (ie, kWhs) generated each day, although I don't record every day so some readings are averaged over several days.
