Perth gets the kind of sun that makes solar worth talking about. Long bright days, heavy daytime usage, and electricity bills that keep creeping up — it all adds up. For a lot of homes and businesses, solar panel installation Perth is one of the few upgrades that actually pays for itself instead of just looking good on paper.
At Willex Electrical, we install solar PV systems for houses, strata properties, offices, warehouses and commercial sites across Perth. We handle the lot: site inspection, system design, installation, testing, commissioning and aftercare. No handballing, no vague promises, no disappearing once the panels are on the roof.
Willex Electrical was established on 14 July 2021. We operate under Electrical Licence No. EC14820, ACN 651 987 325, ABN 60 651 987 325 and DUNS 651 987 325. Those details matter. They tell you the business is real, licensed and accountable — not just a name on a quote.
From a simple grid-connected rooftop system to battery storage, hybrid setups or larger commercial arrays, we build solar around the property, the load profile and the roof space available. That’s how you get a system that works properly instead of one that just looks impressive in a brochure.
As trusted solar panel installers in Perth, we provide customised solar energy systems for homes, businesses and industrial facilities throughout the Perth metropolitan area.
Our comprehensive solar services include:
No two properties behave the same way. A family home in the suburbs, a warehouse with heavy daytime loads and a retail site with air conditioning running flat out all day will need very different setups. We look at electricity use, roof geometry, shading, budget and future demand before recommending anything.
We use Tier 1 solar modules, quality inverters and proven mounting hardware because solar should last. If the gear is weak, the whole system suffers. Simple as that.
Solar panels are not just about being greener. They’re about keeping more of your money where it belongs.
A well-planned solar PV system can help you:
Perth averages around 5.3 peak sun hours per day, which is a strong number by any standard. That’s why rooftop solar performs so well here. The sun does a lot of the heavy lifting. Your system just needs to be designed properly so you can actually benefit from it.
Putting solar on a home is one of the cleanest ways to cut power bills without changing how you live. Our residential solar panel installation Perth services help homeowners generate their own electricity and rely less on the grid. We install solar systems for family homes, townhouses, new builds, investment properties and lifestyle properties, with each system designed to suit the way the property actually uses power. Residential solar can deliver lower quarterly electricity bills, better energy security, reduced environmental impact, higher property appeal and long-term savings. A 6.6kW system suits plenty of Perth homes, while bigger households, home offices and properties with higher daytime use often need more capacity. We also install solar and battery packages where it makes sense, matching the system to the household rather than simply chasing a number. From panel placement and inverter selection through to final commissioning, we complete every installation to Australian Standards and current electrical requirements. That part matters more than most people realise. A neat install is good, but a compliant, well-balanced install is better.
Businesses across Perth are turning to solar for one reason: it makes financial sense. Our commercial solar panel installation Perth services are built around business load profiles, roof space and future expansion plans, because we do not treat a commercial site like a bigger version of a house. We install commercial solar systems for offices, retail centres, warehouses, manufacturing facilities, schools, medical centres, hospitality venues and industrial properties. Commercial solar can cut daytime electricity use hard, especially where air conditioning, refrigeration or machinery is running during peak sun hours, and that is where the savings show up. We work with business owners to plan scalable solar solutions that suit operational needs, building layout and export limits where applicable. If the site is likely to grow, we factor that in from the start so you are not ripping things apart later.
Perth is one of the strongest solar markets in Australia. That’s not marketing fluff. It’s just the reality of the climate. With high sunshine levels, favourable solar conditions and rising electricity costs, solar panels can deliver solid long-term value. Many Perth property owners choose solar because it offers:
Add battery storage and the system becomes even more useful. Instead of sending every spare kilowatt back to the grid, you can hold onto some of it for the evening when the house is actually using power. That’s where solar starts feeling less like a nice idea and more like a practical upgrade.
The right solar system size depends on electricity use, roof space and the way the property draws power through the day.
A common residential choice for Perth homes. It suits households that want to cut bills without overbuilding the system.
Custom solar arrays for businesses that need larger-scale renewable energy generation.
A strong fit for larger homes, home offices, electric vehicle charging and properties with higher daytime demand.
Best suited to large homes and businesses that want higher solar output and stronger bill reduction.
We recommend the system size after reviewing consumption patterns, roof orientation, shading and future load growth. That’s the part that separates a decent solar job from a frustrating one.
One of the first questions people ask is simple: what does solar actually cost?
The cost of solar panel installation Perth projects depends on several factors, including system size, equipment selection and installation complexity.
Roof pitch, height, orientation and access can affect labour time and installation requirements.
Premium solar modules and quality inverter brands often deliver better output, monitoring and long-term reliability.
Adding battery storage increases system capability and energy independence, but it also changes the overall project cost.
Some properties need switchboard work, protection upgrades or export-related changes before the solar system can be connected.
We give clear, obligation-free quotes with no hidden extras. You’ll know what’s included before anything starts. That should be standard, but it isn’t always.
We inspect the roof, switchboard, electricity usage and property layout to identify the right solar solution.
Our licensed electricians install the solar panels, inverter and electrical components safely and efficiently.
Our team prepares a solar system proposal based on your energy goals, budget and property requirements.
We test the system, confirm it is operating correctly and walk you through how it works before handover.
When choosing solar panel installers in Perth, licensing, workmanship and product selection matter. A lot.

How much can I save with solar panels in Perth?
Savings depend on system size, electricity usage and tariff structures. Many households can significantly reduce their power bills with a properly sized solar system.
Are solar panels worth it in Perth?
Yes. Perth’s high sunshine levels make solar one of the most effective ways to reduce electricity costs and improve energy efficiency.
Can I add a battery to my solar system later?
Absolutely. Many systems can be upgraded with battery storage as your energy requirements evolve.
How long do solar panels last?
Most premium solar panels are designed to perform effectively for 25 years or more.
Do solar panels work on cloudy days?
Yes. Solar panels continue producing electricity in cloudy conditions, although generation levels may be reduced.
Can I sell excess electricity back to the grid?
Yes. Eligible systems may be able to export excess energy and receive feed-in tariff credits through their electricity retailer.
