Perth gets long, hot, dry summers and plenty of clear winter days, which makes rooftop solar one of the most common home upgrades in the city. Picking between solar installers in Perth is harder than picking a panel brand, because the installer decides the system design, the quality of the wiring and whether the paperwork with Western Power and Synergy is done properly.
Perth homes sit on the South West Interconnected System, so most households export to the grid under Synergy’s Distributed Energy Buyback Scheme (DEBS). The WA Government says DEBS pays more for electricity exported between 3pm and 9pm than at other times, which is why many installers now pair panels with a battery or face some panels west to catch afternoon sun.

Best Solar Installers In Perth
1. Perth Solar Force — WA-Owned Wangara Installer With 25 Year Workmanship Guarantee
Perth Solar Force is based at 17 Niche Parade in Wangara and describes itself as Perth owned and operated, with more than 100 employees across WA. The company says it started in 2016 and has installed over 40,000 solar systems, completing more than 90 installs a week. It supplies solar panels, batteries and EV chargers for homes and businesses across Perth and regional WA, and it also handles solar repairs and inverter replacements.
Installs are done by in-house electricians, and the site shows New Energy Tech Approved Seller status, Smart Energy Council membership and SwitchDin accreditation. Its published promise includes a 25 year workmanship guarantee, a 10 year savings guarantee and an in-house service team. The company also displays SunWiz badges naming it the top residential solar and battery installer in WA for 2025 and 2026. It suits households that want a large local installer with its own crews rather than subcontractors.
2. Regen Power — Canning Vale Solar And Battery Installer Since 2003
Regen Power’s head office is at 4/90 Catalano Circuit in Canning Vale, and the company also has offices in Adelaide, Sydney, Brisbane and Melbourne. It reports more than 45,000 installations since 2003. The site describes the business as CEC approved and lists Clean Energy Council and Smart Energy Council memberships. Services cover residential solar, home batteries, EV charging, and commercial and off-grid systems.
Regen Power is a Tesla Energy Certified Installer and an iStore Premium Partner, and it works with brands such as Fronius, GoodWe and Sungrow. It explains the WA battery rebate and Synergy-linked finance on its site, which is useful if you are adding storage to make better use of the DEBS evening export window. The company says most quotes are delivered within 24 hours and shows ProductReview awards from 2021 to 2026. It suits southern suburbs homeowners planning a battery alongside panels.
3. Australis Solar — Osborne Park Installer, WA-Owned Since 2008
Australis Solar has its office at Unit 5, 1 Pitino Court, Osborne Park, and says it has been Perth-based and WA-owned since 2008. The footer shows electrical contracting licence EC15197, and the company uses accredited in-house installers and licensed electricians. Services include residential solar and inverters, battery storage with blackout backup, EV chargers, maintenance, repairs and upgrades, plus commercial solar for businesses and strata sites.
The project examples on its site show the range of work it takes on, from replacing an older 10 panel system in Greenwood to a 25kW array with a 40kWh battery in Parkerville and a combined solar, battery and DC EV charger job in Dalkeith. That makes it a good fit for larger homes, hills properties and owners adding to an existing system. Because the licence number is published, it is easy to check before you sign. It suits buyers who want a long-running local firm that can handle upgrades as well as new installs.
4. PSW Energy — Bibra Lake And Neerabup Installer With Itemised Packages
PSW Energy services Perth and Bunbury from bases in Bibra Lake and Neerabup, and its site says it is affiliated with Perth Solar Warehouse, with Western Australian business history dating to 2013. It publishes electrical contractor licence EC010771 and describes itself as a triple ISO certified electrical contracting business and a New Energy Tech Approved Seller. The core offer is turnkey solar, battery and EV charging packages with itemised pricing.
The company lists Tesla Powerwall Certified Premium Installer status, Fronius partner status and Sigenergy Silver Certified Installer status, which covers the main battery options most Perth buyers ask about. After installation, customers get access to a project portal and an aftercare program. The site notes that it is being updated, so confirm package details and warranty terms in writing. It suits buyers north or south of the river who like to compare line-item pricing before committing.
5. Westsun Energy — Wangara Commercial Solar Contractor With SAA Accredited Installers
Westsun Energy is listed at 1 Distinction Road in Wangara and says it is proudly WA owned and operated. Its installers are described as Solar Accreditation Australia (SAA) accredited. While it does supply and install residential systems, its site leans heavily towards commercial and utility work: EPC, consulting, electrical work, power purchase agreements, maintenance and inverter troubleshooting, along with batteries, EV chargers and heat pumps.
The project list is what sets it apart. Westsun lists six systems for Mineral Resources Limited at sites including Kwinana, Bibra Lake, Applecross and Osborne Park, a 1MW solar and battery project at a Western Power depot in Forrestdale, and DC electrical work on a solar farm at Cataby. That experience with large grid-connected systems matters for businesses that need network approvals and careful design. It suits warehouses, offices and industrial sites in the northern and central suburbs.
6. Solaire Connect — Family-Owned Landsdale Installer With 5,000 WA Installs
Solaire Connect operates from U5/10 Dillington Pass in Landsdale and describes itself as family owned and operated, with 17 years of experience in WA. The company says it has completed more than 5,000 installs across the state. Its services cover residential and commercial solar, batteries, hot water and heat pumps, EV chargers and post-installation servicing, and it helps customers with finance applications and rebate paperwork.
The site states that every figure in a quote is confirmed in writing before commitment, which is a sensible practice when rebates and finance are part of the deal. It does not list licence numbers or a workmanship warranty, so ask for both when you request a quote. A northern suburbs base makes it convenient for homes in Wanneroo, Joondalup, Ellenbrook and nearby areas. It suits families who want a smaller, owner-run business that can also handle hot water and heat pump upgrades in the same visit.
7. Perth Solar Power — Balcatta Electrical Contractor With Tiered Solar Packages
Perth Solar Power is based at Unit 4/6 Corbusier Place in Balcatta and describes itself as a fully licensed and insured electrical services company. It states that its systems are designed by accredited solar personnel and installed by in-house accredited installers, and its site carries a New Energy Tech Approved Seller logo. Alongside solar and batteries, it offers EV chargers for homes and workplaces, LED lighting, energy audits, solar maintenance and emergency electrical callouts.
The company sets out three package levels. Its premium package uses German-engineered panels and European inverters with warranties of up to 25 years, while its classic and economy packages pair panels carrying a 25 year performance warranty with inverters carrying a 5 year warranty. That structure makes it easy to see what you trade off at each price point. It does not publish a founding year or licence number, so check those directly. It suits homeowners who want one electrical contractor for solar and general electrical work.
Southside Solar and Electrical describes itself as a locally owned and operated business in Perth that serves all of the city’s southern suburbs. Its site states that its installers are SAA certified, and it lists residential and commercial solar, battery storage, inverter supply and repair, system replacement, EV chargers and ongoing maintenance. Brands mentioned include Jinko and REC panels and Tesla Powerwall batteries.
The business offers a 10 year workmanship warranty on installations, which compares well with the shorter terms some installers give. As a smaller operator, it is likely to suit buyers who prefer dealing with the same people from quote to commissioning. The site does not give a street address or founding year, so confirm its licence details and insurance before booking. It suits households in southern suburbs such as Canning Vale who want a local team south of the river, including those replacing an older or faulty inverter.
How To Choose A Solar Installer In Perth
Which Accreditations Should A Perth Solar Installer Have?
Installer accreditation for small-scale solar and batteries now sits with Solar Accreditation Australia (SAA), which took over the role previously run by the Clean Energy Council. Retailers can also sign up to the New Energy Tech Consumer Code as Approved Sellers. In WA, the installer also needs an electrical contractor licence, so ask for the licence number and check it with Building and Energy. Federal small-scale certificates usually require an accredited installer, so this affects your upfront price as well as your safety.
How Does DEBS Affect System Design?
Under the Distributed Energy Buyback Scheme, Synergy pays a higher rate for electricity exported between 3pm and 9pm and a much lower rate at other times. The WA Government says eligible residential systems must have a generating capacity between 500W and 5kW, and that you or your installer apply to Synergy for the buyback rate. Rates are reviewed each year, so check the current figures on Synergy’s website. A good installer will model your own usage rather than quoting a standard payback figure.
Is A Battery Worth Adding In Perth?
Batteries let you store midday solar for the evening peak, when grid power is dearer and export rates are highest. The WA Government runs a residential battery scheme for eligible Synergy and Horizon Power customers, and the federal Cheaper Home Batteries program also applies. Rebate amounts and conditions have changed several times, so ask the installer to show the current figures in writing and confirm them on the official program pages before you sign.
Who Handles The Western Power Paperwork?
Western Power manages the network across Perth and the South West, and grid-connected systems need its approval before they are switched on. Most reputable installers lodge the application for you, then help you apply to Synergy for DEBS once the system is commissioned. Ask who is responsible for each step, how long approvals usually take in your area and whether any export limits apply to your street. Delays here are a common source of frustration.
What Warranties Should I Compare?
There are three separate warranties to compare: the panel product and performance warranty, the inverter warranty and the installer’s workmanship warranty. Panel warranties of 25 years or more are common, while inverter warranties are often much shorter. Workmanship cover varies widely; among the firms in this list that publish it, terms run from 10 years to 25 years. Perth’s heat is hard on rooftop equipment, so also ask who handles warranty claims if the installer stops trading.
Conclusion
Across our top solar installers in Perth for 2026, the choice for most homes comes down to scale and service. Perth Solar Force and Regen Power offer large in-house teams and battery expertise, Australis Solar and PSW Energy bring long local track records and published licence numbers, and Westsun Energy stands out for commercial projects. Solaire Connect, Perth Solar Power and Southside Solar and Electrical suit buyers who prefer a smaller local operator.
Get at least two or three written quotes, check the electrical licence and accreditation, and ask how the system will be designed around DEBS and your evening usage. If you are a trades business looking to win more solar enquiries yourself, see our list of SEO agencies in Perth.
