Solar for Your Trade Business: Financing Solar Panels and Claiming the Tax Benefits in Australia

and does not constitute financial, tax or legal advice. Always consult a

Solar panels are one of the most common capital investments Australian

business owners are considering right now -- and trade businesses are no

exception. If you have a workshop, storage facility, office premises, or

even a residential property used partly for business, solar can

meaningfully reduce your electricity costs. The question is how to

finance it intelligently and maximise the tax benefits.

This guide covers the financing options for solar installation, how the

tax deductions work for business use, and what to consider before

committing.

Why Tradies Are Looking at Solar

The maths on commercial solar has improved significantly in recent

years. Electricity prices have risen sharply across Australia, while the

cost of solar systems has fallen. A solar system that might have taken

8-10 years to pay back five years ago might now deliver payback in 3-5

years in many states, particularly with electricity rates above 30-35

cents per kilowatt-hour.

For a tradie with a workshop, compressor, welding gear, refrigerated

storage, or EV charging for electric vehicles, the electricity savings

from a well-sized solar system can be $2,000-$8,000 or more per year

depending on usage and system size.

Financing Options for Business Solar

Equipment Finance / Chattel Mortgage

A solar system installed on a business-use premises is a capital asset

that can be financed through commercial equipment finance. Chattel

mortgage or hire purchase can be applied to solar installations just as

they would for any other piece of business equipment. The system is the

security (or the property it's installed on strengthens the lender's

position).

Repayments are fixed and predictable. If the annual electricity saving

exceeds the loan repayment (which it often does in a well-structured

system), the system is cash-flow positive from day one -- you're paying

less per month than you were paying in electricity bills.

Solar-Specific Financing Products

Several Australian lenders and solar providers offer specific solar

finance products, sometimes with subsidised or interest-free periods as

part of a promotion. These can be attractive but require careful reading

-- the interest-free period may disguise a higher rate that applies

afterwards, or there may be fees for early repayment.

Greenbank, Brighte, and Plenti are among the non-bank lenders operating

in the Australian solar finance space. Compare their total cost against

a standard commercial equipment loan before committing.

Business Loan

An unsecured or secured business loan can fund a solar installation.

Interest rates will be higher than secured equipment finance but the

process may be faster and simpler. For smaller systems (under $15,000),

this can be the path of least resistance.

Paying Cash / Using Business Savings

If your business has accumulated savings and the solar investment makes

financial sense (payback under 5 years), paying cash is worth

considering. You avoid all interest costs and can potentially claim an

immediate deduction under the instant asset write-off provisions. The

return on a solar investment paid in cash is essentially the electricity

savings as a percentage of the capital outlay -- which can be excellent.

Tax Treatment of Business Solar

A solar system installed on business premises is a depreciable business

asset. The tax treatment depends on whether the instant asset write-off

applies in the relevant tax year.

If the instant asset write-off is available for your business size and

the system cost in a given year, you can deduct the full system cost in

the year of installation -- a potentially large deduction that

significantly reduces your tax bill. If the write-off threshold has been

reduced or doesn't apply, you claim depreciation over the system's

effective life (typically 20 years under the ATO's schedule, though many

systems are assigned shorter effective lives in practice).

The interest on finance for a solar system is also deductible as a

business expense, just as it would be for any other business asset loan.

Your accountant should guide you on the specific deductions applicable

in your situation and tax year.

Small-Scale Technology Certificates (STCs)

Solar installations in Australia are eligible for federal government

incentives through the Small-scale Renewable Energy Scheme. This creates

Small-scale Technology Certificates (STCs) based on the system size and

location. These certificates have a market value -- typically

$3,000-$7,000 for a standard residential-sized system, and more for

larger commercial systems.

Most solar installers apply the STC value as an upfront discount on the

system price rather than having you claim them separately. Make sure any

quote you receive reflects this discount, and verify with the installer

that they are an accredited Clean Energy Council installer who can

create and transfer STCs.

What Size System Do You Need?

For a trade business with a workshop or commercial premises, system

sizing should be based on your actual electricity consumption data. Ask

your energy provider for 12 months of interval meter data (your hourly

consumption) -- most providers can supply this. A good solar installer

will use this data to size a system that maximises self-consumption

(electricity you generate and use yourself, at full retail value) rather

than just maximising system size.

Electricity exported to the grid earns a feed-in tariff -- typically 5-12

cents per kWh depending on state and retailer -- which is significantly

less than the retail rate you pay for consumed electricity (30-45 cents

per kWh). This means the most valuable solar output is what you consume

yourself, not what you export.

Before You Commit

Get at least three quotes from accredited installers. Check that the

proposed system has a Clean Energy Council accreditation and that the

installer is CEC-accredited. Ask about panel and inverter warranties

(25-year panel warranties and 10-year inverter warranties are standard

for quality systems). Review the payback calculation with your

accountant, particularly the tax treatment in your specific situation.

Solar is genuinely one of the better business investments available to

trade business owners right now -- but only when the numbers are right

for your specific situation and usage profile. Take the time to

understand those numbers before signing anything.
