Decline of financial incentives for solar panels causing surge in household batteries

From the day solar panels are on your roof and sending precious electrons through to an episode of Squid Game in your living room, you are effectively kissing goodbye to the dreaded electricity bill.

Rather than paying the likes of energy retailers such as ActewAGL, solar panels are effectively paying you to supply them with your power.

However, this could be about to change as financial incentives for installing solar panels continue to plummet.

Slowly but surely, energy retailers are paying homeowners less for their excess electricity, causing many to turn to ‘energy storage options’, or batteries.

This money – called a ‘feed-in tariff’ (FIT) – takes the form of credit on your electricity bill. It is basically money you earn by not using all of the electricity you make, instead feeding it back into the electricity grid.

During the years, the FIT rate has decreased to the point it now sits at an average of eight cents per kilowatt. And it hasn’t finished dropping.

The exact amount differs between Australian states, and depends on the plan you’re on and how much energy you’re feeding back.

In the ACT, this amount is decided by the electricity retailer. There is no legislation in place requiring it.

Mondiaux Solar project manager Howard Lian says there is a proposal currently being discussed that would see this situation reversed. The household owner would then pay the retailer to export their energy into the grid.

“Solar panels are now so popular that all the excess electricity is pooling at the grid and it can’t cope with the excess,” he says.

Therefore, your power is now worth less to the retailer so they pay you less for it. The theory is that this eventually would get to the point where the retailers would need to spend extra on infrastructure to cart your extra energy away, and this expense would be passed on to you.

Much of the motivation for homeowners to swallow the substantial upfront cost and install solar panels is built on the promise of receiving FITs, but Howard says people don’t seem put off by the drop.

Mondiaux Solar typically completes 15 to 20 jobs a week in the ACT, but Howard says there has been a substantial increase in 2021. Chances are people who were working from home during COVID-19 lockdown received an enormous electricity bill, quietly swore, and then decided enough was enough.

The ACT Government is attempting to remedy the oversupply situation and make up for the unreliability of renewable energy by constructing a large energy storage facility.

In other words, a very big battery.

It would play a similar role to that of a dam, keeping back the bulk of the electricity and only allowing some over the top when there is too much.

The ACT Government is also helping out people who want to drop their reliance on energy retailers altogether with a rebate called ‘Next Generation Energy Storage’. Launched in 2016, this is one of the biggest battery rollouts in the world and engages local companies such as Mondiaux Solar to install batteries across homes and businesses in the ACT.

On average, a five kilowatt system will deliver a rebate of $4125 off your total battery installation cost.

Howard says when his company transitioned from providing security services to solar in 2017 it recommended its customers hold back on going down the battery route.

Not only were they still wildly expensive at the time, they were also still in their infancy and carried the risk of malfunction, leakage or fire.

Because it was new technology, Mondiaux Solar advised a wait-and-see approach.

“We did quite a few calculations to see whether it was worth it, but the price was just too high,” says Howard.

But he says the time has come when batteries make sense given the technology is now relatively mature and there is government support.

The situation with the energy grid may also correct itself when demand for electricity surges with the influx of electric vehicles. Charging thousands of these vehicles every day could easily see ACT houses and businesses consume twice the amount of electricity they do today.

The electricity grid and your solar panels would then have plenty of work to do.

That $4125 tax-payer funded rebate is a dead loss too.

Lower feed-in tariffs need to be pit in some perspective. The cost of panels is also substantially cheaper.
The warranty on the batteries is less than the payback period. Better to install more panels than buy a battery, IMO.

We have just sorted out the problem from asbestos insulation, have only just begun to sort out the issue with flammable cladding, and are now rushing to install flammable batteries in our garages. Will they all need to be removed by another government program in 10-20 years?

I made enquiries about batteries 5 years ago and the supplier said they had to be installed in a garage and needed bollards around them which effectively took away one car space.

I wasn’t sure that they were “fireproof” either which is alluded to in this article.

If I did buy them then I would be looking at replacing them soon because they degrade. Anyone considering them should factor in this.
