Perth homeowners searching for solar pricing in 2026 will find quotes that vary by thousands of dollars for what looks like the same system. Some of that variation reflects genuine differences in equipment quality, installation standards, and what you get after the job is done. Some of it reflects corners being cut in ways that are invisible on installation day.
This guide covers what a complete solar and battery system costs in Perth in 2026, what government rebates and financing options are available, and what the price difference between installers actually reflects. It is written from the perspective of Positive Energy Solutions, a Perth-based installer that only does solar and battery together — because that is the only approach that makes sense for most Perth households.
1. Positive Energy Solutions Installs Solar and Battery Together — Always
Most solar companies in Perth will sell you solar alone and offer a battery as an optional add-on. Positive Energy Solutions does not work that way. Every installation is a complete solar and battery system — panels, hybrid inverter, and battery storage designed and installed together as an integrated unit.
This matters for pricing because it changes the basis of comparison. A solar-only system exports surplus generation to the grid at Synergy’s Distributed Energy Buyback Scheme (DEBS) rate of 2 cents per kilowatt-hour — a fraction of what it costs to import from the grid at 33 cents. The financial case for including a battery from day one is strong, and it is the only approach Positive Energy Solutions offers.
It also means the pricing in this guide reflects a complete, integrated system. There are no hidden add-ons after the quote.
2. What Every Positive Energy Solutions System Includes
Before looking at prices, it is worth understanding what is in a Positive Energy Solutions system, because not all quotes cover the same things.
- SunPower P-Series panels: 22 panels producing 10.12 kW. Premium N-type TOPCon shingled-cell glass-glass panels, backed by a 30-year product, performance, and service warranty.
- Premium hybrid inverter: SigenStor (SigEnergy) or Sungrow SH series depending on your package and phase requirements — proven hybrid inverters managing solar generation, battery charge/discharge, and grid interaction as a single integrated system.
- Battery storage: 20 to 30 kWh depending on the package selected. Sized for typical Perth household overnight consumption and designed to work with the inverter as a matched unit.
- Omnidian performance monitoring: Every Positive Energy Solutions system is enrolled in Omnidian’s performance assurance programme at no additional cost. Omnidian monitors your system output continuously and contacts you directly if a performance issue is detected — before you notice it yourself.
- 10-year workmanship warranty: Positive Energy Solutions backs every installation with a 10-year workmanship warranty covering the installation itself — wiring, mounting, roof penetrations, and all electrical work.
- Perth-based team: Positive Energy Solutions operates from a Perth showroom with local staff. Your system is designed, quoted, and installed by the same Perth team, and they are available for questions and support after the job is complete.

4. Government Rebates That Reduce Your Upfront Cost
Two government rebate programmes currently apply to solar and battery installations in Perth, and both are already reflected in the Positive Energy Solutions package prices above. Understanding how they work helps you see the full value of what is on offer.
Federal Cheaper Home Batteries Program (CHBP)
The federal government’s Cheaper Home Batteries Program provides a per-kilowatt-hour subsidy on eligible battery storage systems, applied at point of sale. The CHBP operates on a tiered structure that steps down at set intervals — the earlier you install, the higher the rebate you lock in. By mid-2026 the programme has progressed through its initial tiers, but a meaningful subsidy remains. The exact amount depends on battery capacity and the current tier at the time of installation.
The CHBP is applied directly to your invoice. There is no separate claim, no paperwork, and no waiting period. Positive Energy Solutions handles it as part of your quote.
WA Residential Battery Scheme (State Rebate)
The WA state government’s Residential Battery Scheme launched in July 2025 and stacks on top of the federal CHBP. For Synergy customers in the Perth metro area, the rebate is $130 per kilowatt-hour of battery capacity, to a maximum of $1,300. Accessing this rebate requires participation in Synergy’s Virtual Power Plant (VPP) programme, which allows Synergy to draw on your battery during grid stress events — typically for short windows, a handful of times per year.
Like the CHBP, this rebate is deducted at the point of sale by Positive Energy Solutions and is already reflected in the package prices above.
5. Financing: The WA Plenti Interest-Free Loan
If you would prefer to spread the cost over time rather than pay upfront, the WA Residential Battery Scheme includes access to a no-interest loan through Plenti. The loan is available alongside the rebate for eligible WA homeowners and allows you to fund the balance of your system cost without paying interest.
Key loan details
- Loan amount: $2,001 to $10,000, at zero interest.
- Repayment terms: 3 to 10 years. No early repayment fees.
- Income cap: Household gross income must be under $210,000 per year.
- Credit assessment: Standard credit check applies through Plenti. Approval is not guaranteed and is subject to Plenti’s lending criteria.
- VPP participation required: To access either the rebate or the loan, your battery must be enrolled in an approved Virtual Power Plant (VPP) — Synergy’s programme for metro customers, Horizon Power for regional WA. Opting out of the VPP voids eligibility.
- Approved equipment only: The battery and inverter must appear on Synergy’s or Horizon Power’s Supported Solution List. Positive Energy Solutions’ packages include only supported equipment.
- SAA-accredited installer: The installation must be carried out by a Solar Accreditation Australia (SAA) accredited installer. Positive Energy Solutions is SAA accredited.
The loan and rebate work together. The rebate is deducted upfront (already reflected in Positive Energy Solutions’ package prices), and the loan covers a portion of the remaining cost at zero interest. We can walk you through the application process as part of the quoting conversation.
6. Single Phase vs Three Phase: Which Do You Have?
Your electricity connection type affects which packages are available to you. If you are unsure, check your switchboard — single-phase connections have one main circuit breaker; three-phase connections have three.
- Single phase: The majority of Perth suburban homes are single phase. Single-phase packages are slightly simpler to install. The 5 kW grid export limit on single-phase connections is managed through the hybrid inverter’s export control settings.
- Three phase: Three-phase connections are common in larger homes, homes with ducted reverse-cycle air conditioning, and some newer estates. Three-phase inverters distribute load more evenly and support higher continuous draw from pool heat pumps, EV chargers, and large air conditioning systems.
Positive Energy Solutions’ design process confirms your phase type before quoting. If your home’s requirements suggest a different configuration, we will recommend accordingly.
7. Comparing Quotes: How Positive Energy Solutions Approaches It
Positive Energy Solutions does not have a price-match or price-beat policy. The reason is straightforward: a price-match guarantee requires cutting something to honour it. The things that tend to get cut are the ones that matter most over a 25-year system life — equipment quality, installation standards, warranty depth, and the operational capacity to provide genuine after-sales support.
That said, Positive Energy Solutions is genuinely happy to look at quotes you have received from other reputable businesses and give you an honest assessment of whether the comparison is like-for-like. If the equipment, warranty terms, compliance standards, and service model are equivalent, we will tell you. And if another reputable installer is genuinely a better fit for your situation, we will say that too. The goal is always to help you make the right decision — not just to win the sale.
What Positive Energy Solutions focuses on, beyond price:
- Quality installation: Best-practice compliance on every job, with documentation and workmanship backed by a 10-year warranty. Our previous post on what separates a quality solar installation from a low-cost one covers this in detail.
- Dedicated after-sales support: A Perth showroom and local team available after installation. When something needs attention — warranty claim, inverter query, monitoring alert — you are dealing with the same people who installed your system.
- Local staff: Not a national sales operation with a contact centre. A Perth team you can visit, call, and deal with directly over the life of your system.
- Best-practice compliance: Every installation completed to CEC standards with appropriate documentation. This matters for insurance, grid connection, and any future sale of your property.
8. What Actually Drives Price Differences Between Quotes
When solar quotes vary by thousands of dollars, the difference rarely comes down to panels alone. The bigger gaps are almost always in what happens during and after installation — and most of it is not visible on a quote sheet.
Installation quality
A quality solar installation is measured by how the work is done, not just what equipment goes in. Correct roof penetration sealing prevents water ingress over a decade. Proper cable management reduces fire risk and makes future servicing straightforward. Accurate system design means your inverter and battery are appropriately sized and configured for your actual consumption patterns — not a generic template. And thorough commissioning documentation gives you a clear record that matters if you sell your home or make a warranty claim years later.
These details are difficult to verify from a quote. They are shaped by the experience and standards of the installers doing the work, and by whether the company supervising them has the processes to ensure consistency across every job.
After-sales service: who you can call, and for how long
The most important question to ask about any solar installer is not what they charge. It is what they are like to deal with in year five when something needs attention. A 10-year workmanship warranty is only as good as the business standing behind it. A company that wins business by cutting margins has less capacity to staff a service team, maintain vehicles, and respond to warranty claims years into the future.
Ask how long the company has been operating in Perth. Ask whether they have a dedicated service and support team. Ask what the process is if a performance issue is detected. At Positive Energy Solutions, every system is enrolled in Omnidian’s performance assurance programme — which means a dedicated monitoring service contacts you if a problem is detected, rather than waiting for you to notice something is wrong.
Who are you actually dealing with?
Perth has a wide range of solar businesses: locally owned companies with genuine Perth offices and staff, national brands with a Perth address that is a warehouse or a serviced desk, and online-only operations with no local presence at all. The difference matters when something goes wrong and you need to speak to someone who knows your installation.
A showroom is not just a marketing choice. It is evidence that the business is genuinely established in Perth, with the investment and infrastructure that comes with it. When you visit Positive Energy Solutions, you meet the same team that will design your system, install it, and be available afterwards. There is no overseas call centre, no escalation queue, no hand-off to a third party. The people you speak to before the job are the people accountable for it after.
We would genuinely encourage you to visit our Perth showroom before making a decision — whoever you end up going with. Seeing equipment in person and speaking face-to-face with an installer tells you things that a quote on paper cannot.
9. Is Now a Good Time to Install?
The rebate environment in 2026 is the strongest Perth has seen. Two separate government programmes are simultaneously available and already reflected in Positive Energy Solutions’ package pricing. The federal CHBP steps down at set intervals — the current tier is locked in at the time of installation, so installing sooner means a larger rebate. The WA Residential Battery Scheme has a fixed budget allocation and closes when the funding runs out.
The Synergy A1 electricity rate has increased every year. The 33 cents per kilowatt-hour import rate makes self-consumption through battery storage increasingly valuable. The financial case for a complete solar and battery system is strong, and the incentives to act sooner rather than later are genuine.

Frequently Asked Questions
How much does a solar and battery system cost in Perth in 2026?
A complete 10.12 kW solar and battery system from Positive Energy Solutions is priced between $20,150 and $26,190 after applicable government rebates. All packages include SunPower P-Series panels, a premium hybrid inverter, battery storage (20 to 30 kWh depending on the package), Omnidian performance monitoring, and a 10-year workmanship warranty. Prices are inclusive of GST.
Does Positive Energy Solutions offer solar without a battery?
No. Positive Energy Solutions installs solar and battery together on every project. With Synergy’s DEBS feed-in rate at 2 cents per kilowatt-hour versus a 32-cent import rate, exporting surplus solar to the grid is a poor return on your roof’s potential. We design every system to maximise self-consumption through battery storage from day one.
What rebates are available for solar and battery in Perth in 2026?
Two government rebates apply and are already deducted in Positive Energy Solutions’ package pricing. The federal Cheaper Home Batteries Program (CHBP) provides a per-kilowatt-hour subsidy on eligible battery storage. The amount depends on battery size and the current programme tier at the time of installation. The WA Residential Battery Scheme provides up to $1,300 for Synergy metro customers. Both are applied at point of sale — no separate claim is required.
Can I finance a Positive Energy Solutions system?
Yes. The WA Plenti loan is a state government-backed low-interest finance option available to eligible WA homeowners for solar and battery installations. It allows you to spread the cost over time, with repayments structured against the savings the system generates. Positive Energy Solutions can provide guidance on eligibility and the application process as part of the quoting process.
Will Positive Energy Solutions match a lower-cost quote?
Positive Energy Solutions does not have a price-match policy, but is happy to review quotes you have received from other reputable businesses and give you an honest, like-for-like assessment. If the equipment, warranty terms, and service model are genuinely equivalent, we will tell you. If another reputable installer is a better fit for your situation, we will say so. The goal is always to help you make the right decision.
What is the difference between SigEnergy and Sungrow packages?
Both are premium hybrid inverter and battery packages. SigEnergy (SigenStor) packages include a 27 kWh battery — a larger storage capacity suited to homes with higher overnight consumption, pool heating, or EV charging. The SigenStor is a fully integrated AI energy management system. Sungrow SBH packages are available from 20 to 30 kWh using Sungrow’s proven modular battery system. Positive Energy Solutions will recommend the appropriate package based on your home’s energy profile and phase connection.
Does Positive Energy Solutions install in all Perth suburbs?
Yes. Positive Energy Solutions installs across the Perth metropolitan area including the northern corridor, southern suburbs, hills, and coastal areas. Contact us to confirm availability for properties outside the Perth metro area.
How long does the installation take?
Most Positive Energy Solutions installations are completed in one day. Complex roof configurations, three-phase systems, or larger battery installations may require two days. We confirm the installation timeline during the quoting process.
