Solar, batteries and EV chargers can be paid for upfront, with a loan, or through a payment plan offered by a retailer or installer. Each option changes the total cost and the risk you carry.
A loan or payment plan is financing, not a saving. It spreads the cost over time, usually with interest or fees, so the total you pay is higher than the cash price.
The main options are cash or savings, adding to a home loan, a personal or green loan from a lender, an installer or retailer payment plan, and government-supported loan schemes where they exist.
Government programs set their own eligibility, terms and conditions, and change over time. PlaceNest does not repeat their rates or amounts: check the official page before you apply or sign anything.
Compare the total amount you will repay, not just the regular repayment. Look at the interest rate, the comparison rate, establishment and monthly fees, the term, and any early repayment or exit fees.
Ask whether the cash price changes if you use the plan. Some plans that advertise no interest recover their cost through a higher price or fees.
The value of an energy upgrade depends on your usage, prices and the equipment's performance, which can change. Repayments are fixed commitments.
Any estimate you are given — by an installer, a retailer or an online tool — should list its assumptions so you can compare it with a finance offer. Estimates are not promises.
Simple payback is the net upfront cost divided by the expected yearly benefit. It is easy to understand, but it treats a dollar in ten years as worth the same as a dollar today, and it ignores what happens after the payback point, equipment wear, price changes and replacement parts such as an inverter.
Net present value (NPV) adds up every expected future benefit and cost, discounting later years at a rate you choose to reflect the value of money over time. A positive NPV means the expected benefits outweigh the costs at that rate; a negative NPV means they do not. Because both depend on assumptions, look at a range, not a single figure.
Estimates change with your usage, tariff, the system's performance and the discount rate. Ask for the assumptions behind any estimate and how the result changes when the main ones move.
A loan or payment plan changes when you pay, not whether you pay. Interest and fees add to the total cost, so the upgrade has to provide more value to come out ahead.
A finance option shown on PlaceNest that has not been verified by a PlaceNest reviewer is labelled as not verified, and its availability is not confirmed. Always confirm the current terms with the provider.
PlaceNest does not provide credit or financial advice. Where PlaceNest lists finance information, it is general and shows its official source and the date PlaceNest last checked it.
PlaceNest hasn't verified any current government incentives yet, so none are listed here and none are taken off any PlaceNest estimate. Programs change often: check the official government source, and ask your installer what is already included in the quote.
Not always. Check for fees and whether the price is higher than the cash price.
They might or might not. It depends on your usage, prices and the system. Treat any estimate as a guide, and make sure you can afford the repayments regardless.
For a large purchase, it can help. Moneysmart has free guidance on comparing loans.

General information only. PlaceNest's energy guides, and any estimates or incentive lists, are general information and estimates — not personalised financial advice, and not a quote. Programs, prices and rules change: check the official sources, and get written quotes from accredited installers before you decide.
PlaceNest guides are general information, not financial advice. Whether solar, a battery or an EV charger pays off depends on your home, usage and prices.
Any incentive or finance details PlaceNest shows come from a reviewed list, each with its official source and the date it was checked; eligibility is decided by each program. See how incentives work and paying for an upgrade.
