Fritts Solar vs Willex Electrical: which one for solar inverters and components?
Both businesses score well, but they come at solar inverter and component work from different angles. Fritts Solar is a dedicated solar installer with a deep track record on inverter and battery combinations, while Willex Electrical is an electrical contractor whose reviews mention solar inverter swaps alongside EV chargers and aircon work. Here's how they stack up, based on our methodology.
The differences that matter

Fritts Solar's reviews repeatedly detail specific inverter and battery combinations (Fronius, Sigenergy, BYD, Tesla Powerwall) across custom installs, while Willex Electrical's solar mentions are limited to inverter swaps as one of several electrical services.
- Volume of solar-specific feedback. Fritts Solar has 317 reviews with a sub-score of 1.0 on volume, giving far more data points on solar outcomes than Willex Electrical's 81 reviews (0.83 volume score).
- Post-install fault resolution. Fritts Solar is described spending weeks fixing faults at no extra cost on complex systems, a level of aftercare detail not mentioned in Willex Electrical's summary.
- Business focus. Fritts Solar is built around solar as its core trade with named staff covering quote-to-app-training stages, whereas Willex Electrical is an electrician whose named technician Cormac handles solar as one of several services alongside EV chargers and general electrical work.
- Sentiment score. Willex Electrical actually edges out Fritts Solar on sentiment (0.81 vs 0.75), reflecting its spotless complaint record, though this spans all its services, not solar specifically.

What reviewers say
Fritts Solar
Fritts Solar delivers consistent professionalism from initial consultation to system handover. Reviewers praise the team's willingness to listen, explain options without pressure, and complete installations efficiently and tidily. Their after-sales support-app training, troubleshooting, ongoing responsiveness-sets them apart from competitors reviewers have encountered.
The business has named staff (Alvin, Paul, Jenny, the team) customers feel confident asking questions of, and they honour flexibility around scheduling. One reviewer flagged frequent contact during the sales phase, but this did not dampen overall satisfaction. Long-term owners report systems working smoothly over a year in service.
Willex Electrical
All 19 recent reviews are five-star, praising Willex's execution, pricing transparency, and speed. Cormac and his team appear consistently across jobs, arriving punctually, finishing within estimate, and leaving worksites tidy. The strongest pattern is EV charger installations, where reviewers cite quick turnarounds, clear app setup guidance, and rapid responses to follow-up questions via messaging.
The business handles non-standard installs without fuss and explains options before work starts. No pricing disputes, hidden charges, or rework complaints surface in the sample. Several reviewers mention learning about Willex through personal referrals or Facebook ads, suggesting word-of-mouth reputation is strong in the Perth metro area.
Which should you pick?
Pick Fritts Solar if
- You want a large-scale solar installer with hundreds of reviews specifically on system design, panels, inverters and batteries
- You're planning a custom or complex setup (whole-house backup, semi-rural shed) needing named staff across the whole journey
- You want documented aftercare where faults get fixed at no extra cost, even weeks later
Pick Willex Electrical if
- You need a straightforward inverter swap and would rather use a responsive, all-round electrician who also handles EV chargers and general electrical jobs
- You value a spotless complaint-free record and want one technician (Cormac) personally handling the job start to finish
- You're bundling solar component work with other electrical tasks in the same visit
Verdict
Fritts Solar is the stronger fit if solar inverters and components are the main job, its review volume and detail on specific inverter and battery brands reflect a business built around solar as its core trade. Willex Electrical suits someone who wants a trusted, responsive electrician for a simpler inverter swap or who's combining it with other electrical work, but its solar experience is documented far more thinly than Fritts Solar's.
