Ranked picks
Verlek Electrical Solutions
Why it ranks first
A 5.0 rating from 150 reviews, with recent activity and no negative feedback in the review set. Owner Lee is praised for explaining work with photos and finding cheaper fixes, including one pole repair quoted at $10,000 elsewhere that came in under $1,000.
Pros
- Responds within 30 minutes, next-day booking
- Owner oversees jobs personally
- Certifies and tests systems, then trains the customer
- Transparent pricing with no surprises
Watch out: Reviews cover electrical and bore work as well as solar, so it is less of a pure hot water specialist.
Services: Solar Hot Water Systems, Residential Solar Panel Systems, Solar Energy Company, Solar Energy System Service
Ember Plumbing & Gas
Why it ranks second
A 4.9 from 410 reviews, well above the 4.48 category average. Many reviews name technicians for on-time, neat installs, and quotes match final bills. Based in Morley, it serves the whole metro area.
Pros
- Published pricing, Vulcan from $1649 installed
- Free removal of the old system with install
- Fast response, next-day booking common
- Master Plumber accreditation and WA registration

Tap Doctor Plumbing Perth
Why it ranks fifth

Pros
- Large team of well-regarded installers
- STC and rebate applications handled in-house
- Multi-brand support including Fronius and iStore
- Honest sizing advice
Watch out: Some customers report slow or disputed warranty claims and unanswered support requests.

PV Spark
Why it ranks seventh
A 4.8 from 74 reviews. Hamza is singled out for in-person, no-pressure advice, and installs are quick, with fair pricing against the market. Remote and off-grid jobs feature in the reviews.
Pros
- No-pressure personal sales approach
- Fast installation turnaround
- Fair pricing
- Five-year-old systems still performing well

Services: Solar Hot Water Systems, Solar Panel Maintenance Service, Solar Energy Company, Solar Energy System Service

URECO Solar
Why it ranks #11
A 4.5 from 109 reviews. Reviewers praise fast responses, fair pricing and installs sometimes done the next morning, with Envirosun, iStore and Reclaim heat pumps mentioned. One customer got phone guidance within minutes when a four-year-old system failed.
Pros
- Fast emergency response
- Next-day availability
- Honest comparisons with competitors
- Pairs with solar PV to cut power bills

Services: Solar Hot Water Systems, Residential Solar Panel Systems, Solar Energy System Service, Solar Energy Company
Solahart Cannington
Why it ranks #12
A 4.5 from 22 reviews, so treat the score with some caution. Reviewers describe same-day or next-day temporary units and replacements within days, with Max, Wendy and Kevin named for patience.
Pros

iStore
Why it ranks #13
A 4.7 from 27 reviews, medium confidence. Reviewers report real bill cuts and clean installs, and the slim battery fits tight spaces. It is a product brand with local support.
