2011-2012 PV roll out

here’s one quick caveat on the ranking below: my solar power installation data for the countries was for the end of 2011, whereas my solar power installation data for the states (courtesy of GTM Research, via Scott Burger) was for the end of Q3 2012. So, basically, the states had a 9-month advantage (which can be rather significant when it comes to solar — the fastest growing energy industry).

Rooftop PV in Australia

Australia installed more small-scale rooftop PV (systems less than 10kW) on households in 2011 than Germany, with 795MW vs 759MW.  It now has an estimated 1.7 gigawatts of solar PV installed on rooftops, and is expected to get to 2,000MW by the end of the year. The Australian Energy Markets Operator recently said there could be 12,000MW to 18,000MW of rooftop solar PV in the country by 2030. Sunwiz and Solar Business Services say 18,000MW is conceivable by 2022.

Cost of PV vs gas


World's largest - India

The Gujarat Solar Park switched on additional photo-voltaic capacity bringing India's solar capacity to 900 MW. The park, begun in December 2010,  now accounts for nearly two-thirds of that capacity.

The Gujarat State aims to increase it's capacity to 968.5 MW by December 2012.  India aims to have 3% of its national capacity derived from solar by 2013, and based on the commissioning of recent projects, it set to exceed these targets. India intends to derive 15% of its capacity from renewables by 2020.

If every Australian house had PV

A study, conducted by solar provider Energy Matters using government data, found that if every suitable rooftop in Australia was turned into a solar power station, the amount of energy generated would supply more than 134.8 per cent of the country’s residential electricity needs, and would drive down power prices from an average of 30c per kilowatt-hour to 7c/kWh.

According to Energy Matters, there is just under 400 square kilometres of available roof space on residential roof tops in Australia that could accommodate solar panels – equal to the size of inner Melbourne. By the company’s calculations, each one of the suitable houses could theoretically hold an 8kW, 32-panel solar power system. The cost for each system at the current market rate would be less than $14,000.

These houses would then generate 36kWh per day; and with the average household currently consuming 18kWh per day, the excess electricity would earn the household between $2100 and $3,200 per year. This way, the study estimates each household’s solar system would be paid off in between four and six years.

As for the cost of the installation, the study finds this would represent 8 per cent of Australia’s yearly GDP, or 0.4 per cent per year when amortised over 20 years. This compares to the $15 billion Australia currently spends on electricity each year, which amounts to 1 per cent of GDP.

What would happen to Australia’s current electricity production facilities under this scenario? “There would be almost no need for base load power stations on a sunny day,” said Brass. “Australia could close down most of its coal-driven power stations overnight, except for those in heavy industrial areas. Under-utilised gas fired peaking plants, which are already in existence, would be called upon to generate Australia’s night time and cloudy day electricity needs. Shutting down Australia’s coal power stations alone would mean our emissions targets would be met almost immediately.”
