Victorian Solar Slowdown – SunWiz’s view, and how we can help

The Victorian government seems to have inadvertently resurrected Australia’s solar coaster with its Solar Homes program, bringing back memories of feed-in tariff & STC multiplier application deadlines of yore.

Since coming into effect in July of last year, the Solar Homes rebate has helped to propel Victoria to an unprecedented position at the top of of the charts; historically, the state has had one of the slowest rates of solar uptake.

But as with many incentives, it’s all fun and games until a deadline approaches or the funds/allotment run out. (Although we can also point out that – at least since the Abbott years – the steadily reducing but long-standing STC discount available through the national RET has been a great example of how an incentive can even-handedly support a market rather than engendering unnecessary volatility.)

For the Victorian Solar Homes scheme, the solar coaster reared its head for the first time in April 2019, when the rebates were exhausted for the financial year. This left a months long window with ‘no oxygen‘ for installers in the state as many homes held out on purchasing a system until the program reopened in July – with interest-free loans and new incentives for home batteries & solar hot water systems.

Charts below show just how dramatically the Solar Homes Package has impacted the Victorian solar market.

Chart 1 below shows the quote volume (in kilowatts) put through SunWiz’s PVSell software for residential systems in select states relative to the same volume 12 months prior, making it a fairly accurate bellwether for consumer interest in solar.

Editor: note we have identified a large part in the growth shown is due to rapid PVsell uptake. The chart below is smoothed and normalised, showing the average weekly residential capacity of our larger users. The growth is not quite as astronomical, but certainly shows the sales imperative created by the re-opening of the Rebate.

For many weeks from when the Solar Homes Package v1.0 came into effect in August, quote volumes were up by 150%. The clear exceptions are a) the Christmas holiday period and b) the weeks following the temporary closure of the scheme in April. Business started to pick back up again in late June as consumers readied themselves for its reopening – with a massive spike at the end of the month (300% over the previous year’s volume for that week).

Chart 2 below shows the anticlimax of that moment, with the month’s allotment of solar PV rebates running out in just three days. Under the new version of the Solar Homes Package (which was rejigged following April’s chaos), the next round will be released at the beginning of each month. This means that customers and installers alike will once again have to hold their breath until 1 August.
