In Sydney, which side of the network boundary you're on changes the project
Two distributors split the metro area and they don't share rules. New South Wales is also the one state that pays for demand reduction, which can make storage the better half of the decision.

Incentives
What New South Wales actually offers
There is no New South Wales rebate for commercial solar panels. The federal STC discount is the only up-front reduction, and it comes off the installer's invoice rather than arriving as a payment.
What New South Wales does have, and no other state matches, is the Peak Demand Reduction Scheme. It pays for capacity that can reduce demand during peak periods, which makes it a storage and demand-management mechanism rather than a solar one.
For a Sydney business with a sharp afternoon or evening peak, that changes the order of the decision: the solar case and the storage case are worth running separately, and the storage case may be the stronger of the two.

Connection
Connecting in Sydney: two networks, two sets of rules
Sydney is split between two distributors. Ausgrid covers the CBD, the inner suburbs, the north and the east; Endeavour Energy covers the south-west and the outer west. Essential Energy takes over beyond the metro. They do not share connection thresholds or export rules, so which side of the boundary a site sits on genuinely changes the process.
Ausgrid and Endeavour Energy set their own thresholds for where a connection moves from a simple notification to a full application with an export assessment. Confirm which network a site sits on before assuming a timeline — the boundary runs through the middle of the metro area.
Export limiting is common on constrained inner-city feeders and in parts of the outer west. A system can still be worth building with exports capped, but the payback arithmetic changes and the proposal should show it that way rather than assuming full export.

Storage
Solar, storage, or both
Most Australian commercial sites should size solar against their daytime load and treat storage as a separate question. Sydney is the place where that second question is most often worth asking, because the Peak Demand Reduction Scheme puts a value on capacity that can cut demand at the right moment.
That does not make a battery right for every site. It makes the arithmetic worth running properly, against your actual demand charge and your actual peak, rather than against a rule of thumb. The battery page sets out how that works.
The full method is on the cost and payback page, and the installation page covers what happens once a proposal is accepted.

Questions
Sydney questions
Is there a NSW rebate for commercial solar?
Not for solar panels. The federal STC discount is the only up-front reduction on the system itself. What New South Wales has that other states don't is the Peak Demand Reduction Scheme, which pays for capacity that reduces demand at peak times — a storage and demand-management mechanism rather than a solar one.

Which network operates in Sydney, Ausgrid or Endeavour Energy?
Both, and which one you're on changes the process. Ausgrid covers the CBD, inner suburbs, the north and the east. Endeavour Energy covers the south-west and the outer west. Essential Energy takes over beyond the metro. They set their own connection thresholds and export rules, so a quote built on the wrong one can have the wrong timeline in it.
How much does commercial solar generate in Sydney?
Around 1,380 kWh per kW of installed capacity a year on a well-oriented roof. That's below Brisbane and Perth and slightly above Melbourne. A 50kW system produces roughly 69,000 kWh annually, though shading in dense inner-city areas can move that more than the headline figure suggests.
Should a Sydney business look at a battery as well?
More often than elsewhere, because of the Peak Demand Reduction Scheme. If your site has a sharp, predictable peak the storage case is worth running separately from the solar case, and it may be the stronger of the two. We'd rather tell you that than sell you a larger array.
