Australia, one of the world leaders in the absorption of roof solar panels for households, has again broken its own record in the number of installed solar panels per year. In 2020, the installations increased by almost 30 percent compared to the previous year, according to an analysis by the Australian national scientific agency CSIRO.
Data collected by energy efficiency experts and reported in the CSIRO statement, come from the Australian Clean Energy Regulatory Authority, a national body whose mission is to reduce the country ‘s carbon emissions and accelerate its use of clean energy.
It shows that while their federal government leaders lag behind in climate, everyday Australians are doubling renewable energy, installing more rooftop solar panels than ever before and increasing the size of their rooftop fields.
“Persistent low technology costs, higher work from home appliances and a shift in household spending on home improvements during the year COVID-19 played a key role in increasing rooftop solar PV systems within SRES, ” he said Mark Williamson, CEO of Clean Energy Regulator, refers to a national system in Australia that allows homeowners and small businesses to recoup some of the cost of placing panels on their roofs.
The record year is, in fact, just another year for books for the sun-drenched country, which has seen a year-on-year increase in installations as renewables costs have fallen. In 2018 roof solar installation jumped by almost 60 percent since 2017.
“Australia is one of the sunniest places on the planet,” he said Michael Ambrose, a senior experimental scientist at CSIRO, who led the CSIRO analysis, which reflects a separate annual assessment of the Australian rooftop solar market from the consulting company SunWiz.
“We lead the world in photovoltaic capacity per capita to 591 watts per person, which is almost eight times the global average,” he said. he said.
Photovoltaics, or photovoltaics, is what scientists often call solar panels, which are made of solar cells stacked together to capture solar energy and convert it into electricity. Capacity is the amount of electricity that a solar system can produce at its peak.
“The [latest] data on solar PV installations show how quickly PV systems have been used in Australia and how the size of PV fields is increasing, ”Ambrose he said.
The data used in the CSIRO analysis from the Australian Federal Clean Energy Regulatory Authority showed that a record 362,000 solar panels were installed and certified under the Small Renewable Energy Scheme in 2020.
At the end of the year, Australia had a total of more than 2.68 million rooftop solar systems in homes – meaning that one in four households now absorbs sunlight and converts it into electricity.
It is expected that the solar capacity on the roof of the earth will increase only with the fact that the installations will trend higher already in 2021, based on early data.
But in the midst of fanfare, there are even bigger issues to be addressed: can Australia’s aging electricity grid handle the huge influx of solar energy – it’s old and it really needs to be upgraded – and solar panels combined with household batteries could in fact maintain a stable grid and increase electricity supply in the event of extreme weather, such as lightning bets.
“How these systems behave when you sit on our roofs can have material impacts on the wider electrical grid,” said UNSW Renewable Energy Researcher Naomi Stringer he said Restore the economy.
“The effects of rooftop solar energy can be particularly acute during fault events when the grid is already taut, which poses new risks to the security of the energy system,” he says. he said.
“However, there are also important opportunities to use solar capabilities on the roof to help restore the security of the energy system.”
Many small Australian communities have seen this potential, facing power outages while fighting fire fronts throughout the country. devastating forest fires of the “Black Summer” and who take matters into their own hands – exit from the grid and installation of own separate solar systems.
But when we take a step back, some scientists say that Australia is catching up with other renewable energy leaders, such as Germany.
Australia may be building new renewable energy infrastructure, including large solar fields and wind farms, per capita ten times faster than the global average, In last years. However, the total amount of energy it produces from renewable sources still lags behind other countries.
“Denmark produces about two-thirds of its electricity from renewable sources – non-hydro – and has a fifth of Australia’s population, so its annual per capita generation is many times higher than in Australia and Scotland,” said renewable energy expert Mark Diesendorf of UNSW Sydney he said Australian Associated Press early 2021.
Solar cell scientists have always tested new configurations with materials other than silicon that can capture more parts of the light spectrum and could be used to make more efficient solar cells – and are breaking record after record, also.
Nothing like a little healthy competition.
