When record rainfall caused flooding in south-east Queensland last February, Steve McLean’s solar installers stayed off their roofs, blowing a $60,000 hole in his company’s budget and setting back what could to have been another record year for his business.
“If we didn’t do a system for five weeks, you can imagine nobody else did. … We were absolutely gutted in February and March,” said McLean, the owner of Gold Coast Solar Systems. “If you take that number off the market, well, it was disastrous.”
Bad weather and Covid-related supply disruptions for solar panels and installers contributed to a 14% drop last year in new solar photovoltaic (PV) capacity added to Australian rooftops. Total capacity was 2.76 GW nationally, making it the third-highest annual number behind 2021’s 3.21 GW and 2.94 GW in 2020, Green Energy Markets said.
But after that first setback, the industry regained its balance, with December the third busiest month on record with 306 MW installed, Green Energy Markets project manager Emily Perin said.
Electricity price spikes from the middle of last year, and the prospect of more to come, also boosted PV demand. “Things really started to pick up the rest of the year,” Perin said. “But obviously, it didn’t make up for the first half.”
He said the industry “will likely see a modest increase in 2022” provided Covid-related supply issues do not return. However, higher interest rates will squeeze discretionary spending by households and businesses, Perin predicted.
Rising global demand for photovoltaics, particularly as nations scramble to find alternatives to Russian energy after the invasion of Ukraine, could also boost solar panel prices in the short term, he said.
The average size of home PV systems continued to increase, surpassing 7.5 kW, Green Energy Markets said.
On the Gold Coast, McLean typically installs systems of 10 to 13 kW capacity. “I try to oversize at least 30% to future-proof [customers] against the rising cost of energy,” he said. “We know that it will continue to increase regardless of the policies around governments and networks.”
Last month, the federal government imposed year-long caps on gas and black coal prices in an attempt to limit rising energy prices driven mainly by the fallout from Russia’s war on Ukraine. Even so, energy costs are expected to rise 23% this year.
An average customer with a quarterly electric bill of $600 to $800 who installs a large PV system may be well positioned to add a battery later and “be almost completely self-sufficient,” McLean said. Although including an electric vehicle in the household adds “quite a considerable amount to energy consumption,” possibly doubling it.

Managing director of industry analysis group SunWiz, Warwick Johnston, said home battery sales likely topped 43,000 units last year.
“The number of installations that occurred in 2022 was at least the same as in 2021 with the potential to be 10% to 20% higher,” Johnston said.
Household battery consumption continues to rise, allowing the sector to grow even though the number of new systems fell by around a fifth in 2021.
SunWiz data indicates that 15% of new systems include energy storage systems.
The increase in uptake came despite battery prices rising in 2022 in part due to demand for lithium to power expanding fleets of electric vehicles entering global markets.
The average price of a watt-hour was about 65 cents in early 2020 and started 2023 at about 93 cents, SunWiz said. The price increase in some cases was the first in more than a decade for a technology that, like photovoltaics, has tended to get cheaper over time.
Payback periods for PV systems alone are five to six years on average, while adding storage typically doubles that. But for sun-blessed South Australia, the payback period is less than seven years for the combined systems.
Buyers are not always motivated by price alone. Mr Johnston said the strain on electricity supplies, with the main grid nearing a breaking point last June, was causing some households to look for “electricity insurance, called a battery”.
Similarly, the widening gap between what households pay for the energy they receive from the grid versus what they receive for exporting surplus electricity increases the appeal of storage.
Given the expected expansion of lithium supplies, the cost of batteries will likely decline. “When they come down significantly, there will be a lot of interest,” Johnston said.
Meanwhile, solar and battery installer McLean is “under pressure” to handle a growing number of enquiries, including battery enquiries. “And I think that will continue.”
McLean said governments should subsidize batteries, as their increased use also helps avoid costly grid investments.
Targeting 20% of the population, for example, would have “a massive impact on the need for the grid to supply fossil fuels,” he said. “This is the real game.”
A: Solar panels can be a valuable investment for a homeowner, with benefits that extend beyond resale value.
