About HEA
Why HEA
We're not the biggest solar company in Bendigo. We're the most precise.

Jesse & Alexis Heffernan
Heffernan Electrical Automation is Jesse and Alexis Heffernan — a licensed electrical contracting team based in Bendigo, Victoria. We specialise exclusively in solar, battery storage, and EV charging for residential homeowners in central Victoria.
We started HEA because we kept seeing the same problem: homeowners being sold systems that were sized to maximise the installer's margin, not the customer's payback. Oversized systems. Generic quotes. No one checking the actual bill data.
So we built a different kind of process. One that starts with your real consumption data and ends with a system designed around how your household actually uses energy.
Why “Right-Sized, Not Biggest” Matters
The solar industry pushes bigger systems because bigger means higher margin. We push the system that pays itself off fastest for your specific household.
The Oversizing Problem
- ✗ System sized to roof capacity, not usage
- ✗ Most generation exported at low feed-in rates
- ✗ Payback period blows out to 12–15 years
- ✗ Customer feels good initially, disappointed later
The HEA Approach
- ✓ System sized to your real consumption profile
- ✓ Maximum self-consumption, minimum wasted export
- ✓ Payback target under 10 years, every time
- ✓ Honest if a bigger system genuinely makes sense
How We Operate
Honesty over sales
If a battery won't improve your payback, we'll tell you. If a smaller system is better for your usage profile, that's what we'll recommend. We're not trying to maximise the sale. We're trying to earn a referral.
Precision over guesswork
We use your actual NEM12 interval data from Powercor — 12 months of half-hourly readings. Every proposal is modelled against real data, not industry averages. Your payback estimate reflects your home, not someone else's.
Direct over delegated
Jesse does the consultation, the design, and the installation. You deal with one person. That person is accountable for the result.
Right-sized, not biggest
The solar industry has an oversizing problem. Bigger systems aren't always better — they cost more, have longer payback, and may not even be worth the roof space. We target payback under 10 years on every job.
