Is A Solar Battery Worth It?
If you’ve been wondering whether investing in a solar battery is worth it, the answer is becoming clearer every day, especially for families here in the Blue Mountains and Western Sydney. At Avery Solar & Electrical, we’ve seen firsthand how solar + battery systems are helping homeowners slash energy bills, reduce reliance on the grid, and enjoy impressive returns on their investment.
The Power of Solar Battery ROI
One of the most common questions we hear is, “How long will it take to pay off my system?” The good news is, for most families, the return on investment (ROI) is surprisingly fast – often between 4 and 6 years.
We’ve recently worked with several local Blaxland households, all with different energy needs, home styles, and budgets. Despite these differences, they all saw over 95% reductions in their annual electricity bills after installing quality solar systems paired with high-performing inverters and, in some cases, battery storage like the Tesla Powerwall 2.
Here’s a quick snapshot of what we’ve seen:
- Energy bills before solar ranged from $1,600 to $3,600 per year
- Systems ranged from 8.6kW to over 10kW, often using Enphase microinverters and premium panels like Trina Solar or REA Solar
- Where batteries were included, systems provided both energy savings and backup power
- ROI ranged from just 4.2 years to 5.5 years, depending on energy usage and system size
These aren’t one-off results. They reflect what’s possible with the right solar design, installation quality, and a bit of forward planning.
How Much Can You Actually Save?
For most households in our region, installing a well-sized solar system can wipe out the majority of your electricity bill. When you add a battery, you gain the ability to store excess solar power for evening use, reducing your need to draw from the grid, especially during peak pricing times.
Here’s what solar + battery systems typically deliver:
✅ Over 95% reduction in annual energy costs
✅ Payback period of 4 to 6 years
✅ Energy independence and blackout protection
✅ Long-term savings of tens of thousands of dollars over the system’s life
The savings are even greater for households with higher energy usage or growing families, where power bills can quickly climb without a solar solution in place.
And with the new Solar Battery Rebate Scheme starting 1st July 2025, those savings could grow even faster. Eligible homeowners in the Blue Mountains and surrounding regions could receive up to $4,000 back on their battery installation—making this the perfect time to explore your options.
Real Local Families, Real Results
From single-storey homes to larger double-storey homes in Blaxland, our local customers are already enjoying real results:
- The Dale family went from paying $3,600+ per year in electricity to just a few dollars a month
- The McNeill family saw their bills drop from $2,600 to almost nothing, with their system paying for itself in just 5 years
- Several homeowners added a Tesla Powerwall 2, giving them peace of mind during grid outages and boosting long-term savings
These outcomes are more than possible, they’re happening right now in your neighbourhood.
