Solar industry consulting firm SunWiz reported Australia installed 3 gigawatts of solar photovoltaic energy projects, with rooftop arrays accounting for the majority of the renewable energy generation.
This growth could be attributed to tariffs as well as household demand for solar energy in the face of increasing costs for grid-powered electricity, Australian-based news source Renew Economy said. In addition to residential rooftop solar installations, commercial rooftops are also increasing in numbers.
"Around Australia, solar power is making its impact felt through reduced electricity bills for solar owners and lower wholesale electricity prices for everyone," wrote SunWiz Founder Warwick Johnston.
Johnston said 14 percent of residences in the country have solar power systems and one in four homes in South Australia have rooftop solar. Queensland had the highest level of solar installations with almost 1 GW installed. The average rooftop system in Australia produces 4.3 kilowatts. Five percent of these systems are larger than 8 kW. Measuring current demand for solar power, installations are between 60 and 70 megawatts per month, down from a high of 180 MW per month in 2012.
