NETCCA commercial roof generates hardest between 9am and 4pm — the exact window your business is open and buying power at its most expensive. eHomes designs, arranges the finance for, and installs 30 kW to 1 MW solar and battery systems for Australian businesses, on your own building or a leased one.

Commercial solar is not a scaled-up home system. The economics are different, and they are better — because a business consumes its own generation while it is being generated.
Every kWh you use on site displaces power bought at your commercial retail rate — worth far more than exporting it for a feed-in tariff.
Rental, chattel mortgage and PPA structures all start at nil capital outlay. The system is paid for out of the bill it replaces.
The Federal Government has announced the small-scale scheme will expand from 100 kW to 1 MW, subject to regulations — bringing an upfront discount to systems that previously missed out.
Four separate line items on a commercial bill, and what solar and storage do to each of them.
The biggest line on the bill. Solar generated on your roof and used on site replaces power you would otherwise buy at your contracted commercial rate, every trading day, for 25 years.
Many commercial tariffs bill on your highest half-hour of the month, not just total usage. A battery sized to shave that peak can cut the demand charge without changing how you operate.
If you trade into the evening — hospitality, gyms, retail, cold storage — stored solar covers the late-afternoon peak window instead of the grid at its most expensive rate.
Self-generation is the only part of your energy cost a retailer cannot reprice. The more of your load you cover, the less a bad renewal can do to you.
The right structure depends on your balance sheet, your tax position and how long you hold the building — not on which one we prefer. We model the options side by side and let the numbers decide.
You buy the system outright and keep every dollar it saves from day one. Highest lifetime return of any structure, and the simplest to explain to a board. Suits a business sitting on cash it wants working harder than a term deposit.
You own the asset from day one and finance the cost over a fixed term. The business takes title immediately, which usually means depreciation and the interest component are treated as business deductions. Terms are commonly 3 to 7 years.
A fixed monthly payment treated as an operating expense rather than a capital purchase, so the equipment is never bought outright. Popular with businesses protecting borrowing capacity for stock, vehicles or expansion. How the arrangement is reported and deducted depends on the accounting standards your entity reports under — your accountant will confirm it.
A third party funds, owns and maintains the system on your roof. You buy only the electricity it produces, at a fixed rate per kWh below what you pay the grid. No capital, no asset, no maintenance obligation. Best suited to large, steady daytime loads.
| Structure | Upfront | Who owns the system | Best suited to |
|---|---|---|---|
| Cash purchase | Full cost | You, from day one | Cash-rich businesses chasing the best lifetime return |
| Chattel mortgage | $0 | You, from day one | Owner-occupiers who want the asset and the deductions |
| Rental / operating lease | $0 | The financier, during the term | Businesses protecting borrowing capacity and cash flow |
| PPA | $0 | A third-party owner | Large, steady daytime loads and tax-loss positions |
Finance is provided by the financier, not by eHomes, and is subject to their credit approval and terms. Accounting and tax treatment depends on your business — confirm it with your accountant before you sign.
eHomes is accredited with commercial energy financiers including Solaris Finance for commercial leasing and Smart Ease for chattel mortgage facilities. Applications are assessed quickly — often the same business day — and we put the repayment schedule next to your modelled savings so you can see the position before you commit.
Most commercial roofs in Australia sit under a lease, and the standard objection is the split incentive: the landlord pays for the system, the tenant gets the cheaper power. It is a solvable problem, and we solve it every week. Here is what each side actually gets.
Whichever you pick, the arrangement gets written into the lease or a side deed. Both sides should take their own legal advice — we give you the technical and financial detail they need to draft it.
The tenant funds the system and keeps 100% of the saving. The landlord grants roof access and consent, and the make-good position is agreed in writing at the start. Works best with five or more years left to run.
The landlord funds the system as a building improvement and recovers it through a rent adjustment or an agreed share of the verified saving. The tenant still comes out ahead, and the landlord holds the asset.
A funder owns and maintains the system. The tenant buys the power at a fixed rate below grid; the landlord receives payment for the roof. Neither party puts up capital or takes on maintenance.
There are two federal certificate schemes and a set of state programs on top. We calculate what applies to your site and apply it in the proposal — you never have to chase a certificate yourself.
Small-scale Technology Certificates are created the day the system is installed and taken off the price as an upfront discount. Today they apply to solar systems of 100 kW or less that also stay within the scheme's annual output limit. The certificate count depends on system size, your zone, and the deeming period, which steps down each January until the scheme ends in 2030.
Changing October 2026: The Federal Government has announced the small-scale scheme will expand to cover systems up to 1 MW from 1 October 2026, subject to regulations — extending the upfront discount to the medium-sized commercial systems that previously fell between the two schemes.
Systems above 100 kW currently sit in the large-scale scheme. Instead of one upfront discount, the system creates Large-scale Generation Certificates each year based on what it actually generates — an ongoing revenue line rather than a one-off deduction from the purchase price.
Which scheme leaves you better off depends on system size, certificate prices and how long you intend to hold the asset. We model both before recommending a size.
The NSW Peak Demand Reduction Scheme pays an incentive on commercial battery installs, on top of the federal certificates. It is the most generous commercial battery position in the country right now. Our NSW page models the rebate, the finance and the tax position in one place — put your system size in and see the number.
Certificate values are set by the market and change. Scheme rules and eligibility are set by the Clean Energy Regulator and the relevant state scheme administrator. Figures quoted anywhere on this page are indicative estimates, not a quote or financial advice.
We size against your interval data, not your roof. A system that generates more than you use in trading hours exports the surplus for a low feed-in rate — which is how businesses end up over-sold and under-saved.
| System size | Indicative daily generation | Approx. roof area | Typical site |
|---|---|---|---|
| 30 kW | ~120 kWh | ~150 m² | Small warehouse, workshop, childcare centre, medical suite |
| 50 kW | ~200 kWh | ~250 m² | Light manufacturing, gym, supermarket, car dealership |
| 100 kW | ~400 kWh | ~500 m² | Distribution warehouse, club or pub, aged care, school |
| 250 kW | ~1,000 kWh | ~1,250 m² | Cold storage, food processing, large retail centre |
| 500 kW – 1 MW | ~2,000+ kWh | ~2,500 m²+ | Heavy manufacturing, irrigation and agribusiness, logistics hubs |
Generation figures are indicative annual averages for Australian conditions and vary by location, roof orientation, pitch and shading. Roof area is a guide only — final layout follows a site inspection and structural assessment. Above 1 MW we partner-deliver with engineering specialists.
Different load shapes need different systems. A warehouse that runs 7am to 4pm and a cold store that never switches off are not the same job.
Large unshaded roofs and a daytime load that lines up almost perfectly with generation. The most straightforward commercial payback there is.
Three-phase machinery driving high consumption and often a punishing demand charge. Solar plus a peak-shaving battery attacks both lines.
Refrigeration runs around the clock, so a high share of generation is consumed on site and stored capacity earns its keep overnight.
Trading hours run into the evening peak, which is exactly where a battery converts stored midday sun into avoided peak-rate power.
Pumping and processing loads, large shed roofs, and sites where grid upgrades are expensive. Often the strongest case on the list.
Predictable daytime occupancy, steady HVAC load, and organisations with a real reason to show the community what they are generating.
Early-morning and evening peaks with lighting and HVAC running all day — a load shape that suits solar plus storage rather than solar alone.
Big lighting and HVAC load, large canopy and roof area, and EV charging demand arriving whether the site is ready for it or not.
Common-area and multi-tenant metering, where the right structure matters as much as the right system. We work through it with the owner and the tenants.
We pull twelve months of bills and your interval data, map when you actually draw power, and identify whether the win is consumption, demand charges, or both.
Roof structural assessment, layout design, switchboard and metering review, and the grid connection application lodged with your network operator.
System size, rebate value, and every finance structure modelled side by side — payback, cash-flow position and the assumptions behind them, in writing.
One project manager from go-ahead to grid sign-off, staged around your operating hours by accredited installers and licensed electrical contractors. Monitoring configured and generation reporting handed over at commissioning.
A NETCC Approved Seller under the New Energy Tech Consumer Code, with accredited solar designers and installers and licensed electrical contractors on every job. The accreditation that carries the warranty obligations.
A single eHomes project manager from bill analysis to sign-off. You get a name and a number, not a ticketing system.
Adelaide HQ with teams in Melbourne, Sydney, Brisbane and the Gold Coast — so a multi-site rollout runs to one standard, not four.
Every proposal shows the assumptions: tariff, self-consumption rate, degradation and certificate price. If you disagree with an assumption, change it and see what happens.
Warranty and service handled by our own team here, not an overseas hotline. The people who installed it are the people who fix it.
Residential and commercial. The commercial jobs get the same install standard as the homes, with the engineering the scale demands on top.
Pulled live from Google. Every review is from a real customer install.
Commercial pricing is quoted per project, because the cost per kW falls as the system gets bigger and varies with roof type, switchboard work and grid connection requirements. The number that matters is not the price — it is the payback. We model system cost, rebate value, annual saving and finance repayments together so you can see the cash-flow position from month one. Depending on your tariff, load shape and system size, commercial projects commonly model out to a payback in the mid-single-figure years on a 25-year asset — your own numbers are confirmed in the proposal, not assumed here.
Yes. Chattel mortgage, rental and PPA structures all start at nil capital outlay on approved applications. Where the system is well sized against your load and the term is set sensibly, the monthly repayment can land below the bill reduction, which puts the business ahead on cash flow from early in the term rather than waiting years to break even. Whether that holds on your site depends on your tariff, usage and the term you choose — we show it in the modelling. Finance is subject to the financier's credit approval.
It is set by your load shape, not your roof size. We size against twelve months of interval data so the system covers what you consume during trading hours without over-generating into a low feed-in tariff. As a rough guide, 30 kW generates about 120 kWh a day and 100 kW about 400 kWh a day in average Australian conditions.
Solar systems of 100 kW or less currently create Small-scale Technology Certificates, taken off the price as an upfront discount, subject to the scheme's annual output limit. Systems above that create Large-scale Generation Certificates annually based on actual generation. The Federal Government has announced the small-scale scheme will expand to cover systems up to 1 MW from 1 October 2026, subject to regulations. NSW businesses can also access the Peak Demand Reduction Scheme incentive on commercial batteries, on top of the federal certificates.
Yes, and it is common. There are three workable structures: the tenant funds and owns the system with the landlord's written consent; the landlord funds it and recovers the cost through a rent adjustment or an agreed share of the saving; or a third party owns the system under a PPA or roof lease and neither party puts up capital. The arrangement gets documented in the lease or a side deed, including the make-good position at the end of the term.
Under a lease or rental you pay a fixed monthly amount for the equipment regardless of how much it generates. Under a PPA you pay only for the electricity produced, at a fixed rate per kWh below the grid rate — if the system underperforms, you pay less. A lease suits businesses that want a predictable fixed cost and an ownership option at the end. A PPA suits large, steady daytime loads and businesses that want no asset and no maintenance obligation at all.
The treatment depends on the structure. Under a chattel mortgage the business owns the asset and typically claims depreciation plus the interest component. Under a rental or operating lease the payments are generally treated as an operating expense. Under a PPA you are simply buying electricity. eHomes is not a tax adviser — get your accountant to confirm the position for your entity before you sign anything.
If your load sits inside daylight hours, solar alone usually does the job. A battery earns its place in two situations: when your tariff bills you on peak demand and shaving the monthly maximum is worth real money, or when you trade into the evening and would otherwise buy peak-rate power after the sun goes down. We model the battery separately so you can see whether it pays for itself on your site rather than in general.
A 100 kW system is typically two to three weeks on site from go-ahead to commissioning. The variable is the grid connection approval from your network operator, which can run longer on larger systems — we lodge it early and keep you updated rather than letting it surprise you at the end.
Almost all of the work happens on the roof while you operate normally. The exception is switchboard tie-in and commissioning, which needs a short planned shutdown. We schedule that around your operating hours — early mornings, weekends or a shutdown period — and confirm the window with you well in advance.
It depends on the structure, which is exactly why we settle it before you sign. A tenant-owned system can often be removed and relocated, or sold to the landlord or incoming tenant at written-down value. Under a PPA or roof lease, the agreement sits with the building and transfers with it. We document the position at the start so there is nothing to argue about at the end.
