ADD MORE SOLAR PANELS SA
Your home has changed. Your solar can too
Many systems in South Australia were sized years ago, for a home that used less power. Since then, plenty of households have added air conditioning, an electric car, a heat pump or a pool, or moved off gas. A small system that once covered the daytime load now falls well short.
Adding panels, or upgrading the system, lets your solar keep up with how you use power now.
When it makes sense
- Your system is 5 kW or smaller and more than a few years old
- You’ve bought, or plan to buy, an electric car
- You’re moving to heat pump hot water or an induction cooktop
- You’re adding a battery and want it full each day
YOUR OPTIONS
Add panels, add an inverter or start again
- Add panels to the existing inverter. Possible when the inverter has spare capacity.
- Add a second system. New panels with their own inverter, alongside the old system.
- Replace and upgrade. A new, larger system, sometimes with a hybrid inverter ready for a battery. Often the best choice when the old inverter is near the end of its life.
We check your inverter, roof space and switchboard, and tell you which option gives the best result for the money.
REBATES AND APPROVALS
Solar rebates drop on 1 January 2027
New solar panels earn small-scale technology certificates, which come off the price. The number of certificates drops each January until 2030, and on 1 January 2027 it falls by about a fifth. A system installed before then gets the larger discount.
SA Power Networks sets limits on how much a home can export, which affects how big a system can go. We handle the approval and the Relevant Agent setup, and a switchboard upgrade if one is needed.

COMMON QUESTIONS
Questions about adding panels
Often, yes. It depends on your inverter’s spare capacity, your roof space and SA Power Networks’ export limits. We check all three before quoting.
Usually not on the same string, because panels need to match. New panels normally go on their own string or their own inverter.
Yes. Any change to a grid-connected system needs approval, and we apply for you.
Yes. Solar panels earn small-scale technology certificates that come off the price. The discount drops on 1 January 2027.
It depends on whether you run short of solar during the day or waste it. We look at your bills and monitoring and tell you which pays back first.
