2 GW of Solar PV Pointed in the Wrong Direction in Australia?: Filed under: Energy News

2 GW of Solar PV Pointed in the Wrong Direction in Australia?: Filed under: Energy News

McHugh says rooftop PV could play a major role in reducing network costs, because the price of these systems had fallen so much that they were economically attractive for households to install. However, under the current tariff arrangements, most systems – and it is estimated more than 2,100MW of rooftop solar will be in place in Australia by the end of the year – face north because that is where they produce most electricity, and deliver the best returns for households. But McHugh says that if these systems were facing west, they would correlate with peak demand on the grid, and make a major contribution to lowering network costs. West-facing panels could reduce system capacity by 75 per cent of their rated output, and one 1.5kW system could offset a 1kW air conditioner at peak times. This could be significant, given that some forecasts put the extent of solar PV at 12,00...
