Solar photovoltaic (PV) system prices at the beginning of April 2013 are on average lower than they were for the previous month. However, further examination of figures from each of the 7 cities and 5 system sizes included in the index reveals a few discernible trends. One is a clear downward movement in average prices for all system sizes in Sydney, Perth, and Canberra in an apparent (possibly temporary) easing of the last several months’ increases there. Another trend is the continuing tendency for systems in Melbourne and Brisbane (particularly those under 3kW, kilowatts) to become more expensive on a per-watt basis. Larger systems continue to offer the best value for money.
