Solar and batteries for strata and apartment buildings
Cut the common-area power bill that every owner pays through their levies. We design solar and shared batteries around your building's real usage, and give the owners corporation the numbers it needs to vote.
- Built on your common-area bills and interval data
- Eligible incentives may apply, including BESS3 for shared batteries

Every apartment building has a power bill nobody sees directly: lifts, corridor and car park lighting, ventilation fans, pumps, gates and pool equipment. It's paid from the levies. Those loads run every day, many around the clock, which makes them a good match for solar. A shared battery can carry the savings into the evening, when power costs the most.
Why strata solar projects stall
- A shared roof means a shared decisionThe roof is common property, so the owners corporation has to vote. Without clear numbers, the motion gets pushed to next year.
- Quotes you can't compareDifferent system sizes, brands and assumptions make it hard for a committee to choose.
- Who gets the benefitCommon-area solar lowers levies for everyone. Sharing power with individual apartments is possible, but it needs the right metering and a fair way to split it.
- Roof space and accessPlant rooms, lift overruns and setbacks limit the usable roof, and access needs planning.
What fits a strata building
Solar for common areas
Sized to the building's daytime common-area load, so most of the power is used on site rather than exported for a small credit.
Learn more →A shared battery
Charges from solar or off-peak power and runs the common areas into the evening. Batteries from 20 to 200 kWh may be eligible for the NSW BESS3 incentive.
Learn more →A common-area bill review
Many buildings sit on whatever rate the last contract rolled onto. It's the quickest win, and there's no fee if we can't find a saving.
Learn more →EV charging, ready for later
If residents are asking about chargers, we size the switchboard work so EV charging can be added without starting again.

Already have solar? We check whether it's producing what it should and fix what's wrong, whoever installed it.
Learn more →Getting it through the owners corporation
In NSW, solar, batteries and EV chargers count as sustainability infrastructure. The owners corporation, not just the strata committee, needs to pass a sustainability infrastructure resolution at a general meeting, and it passes with 50 per cent or more of the votes at that meeting. Your strata manager can put it on the agenda at the AGM or call an extraordinary general meeting. Other states have their own rules, and they change, so we check what applies to your building before anything goes to a vote. Batteries up to 200 kWh usually also need a Complying Development Certificate from a private certifier, so we include it in the quotes the owners vote on.
Simple, and the numbers come first
- Send the common-area billsPower and gas bills for the common property. We can request the interval data with a signed letter of authority.
- Site check and designRoof, switchboard and meter checks, then a design sized to the building.
- Numbers for the ownersA plain-English summary for the committee: cost, estimated savings, payback, incentives and funding options.
- Vote and approvalsWe can help brief owners before the meeting. Once the resolution passes, any approvals are lodged.
- Install and monitorInstalled by our licensed partner, then monitored so the building can see what it's saving.
Common questions
Who pays for solar on a strata building?
Usually the owners corporation, from the capital works fund, a special levy or finance. Because it lowers the common-area bill, the saving flows back to every owner through the levies.
Can solar power individual apartments?
Common-area solar is the simplest. Sharing solar with individual apartments is possible with the right metering, but it costs more and needs a fair way to split the power. We'll tell you whether it makes sense for your building.
Is a battery worth it for our building?
It suits buildings with steady common-area loads into the evening, like lifts, car park ventilation and lighting, especially alongside solar. For a small block with little common-area use it's harder to justify, and we'll say so.
What is BESS3?
A NSW incentive under the Peak Demand Reduction Scheme that takes part of the cost off a shared battery of 20 to 200 kWh, in a building with at least 4 units. Eligible incentives may apply. Read our BESS3 guide.
What do you need from us?
12 months of common-area power bills, the number of apartments, and roof access or plans if you have them. We can request the interval data for you.
Do you work outside NSW?
Yes. We're Sydney-based with licensed partners in every state. Strata rules and incentives differ by state, so we check what applies to your building.
