Eco Spark Electrical & Solar
Sam diagnosed and fixed a botched solar battery install that an interstate contractor left behind — no replacement, just a proper repair.
The team's ability to remediate botched solar battery work originally done by another contractor is worth noting for homeowners dealing with an inherited or malfunctioning system, since Sam is specifically named as the technician who diagnosed and fixed the problem rather than recommending a full replacement. For homeowners weighing up whether 33 total reviews is enough to go on: the sample we analysed covers nearly nine years of continuous trading with not a single sub-five-star review in the 26 we reviewed, which gives a clearer signal than a large but mixed review pool. Ask Scott directly about lead times for battery installs and whether the team covers your specific suburb, as the business works across both the northern Adelaide metro and Gawler region.

About Eco Spark Electrical & Solar
Scott, who runs Eco Spark day-to-day, is the consistent touchpoint customers mention for quoting, communication, and follow-up after jobs are done — reviews suggest he contacts customers post-installation to confirm they're happy, which is uncommon in the trades. On the tools, named technicians Troy, Riley, Charlie, Blake, and Sam each draw specific praise: Sam in particular is called out for diagnosing and rectifying poor-quality work done by a previous interstate contractor, suggesting the team is comfortable stepping into remediation jobs where solar battery wiring has gone wrong. The business spans a wider range than the solar category implies — commercial shed electrical fit-outs, off-grid solar systems, new home and shed builds, pergola lighting, appliance installs, and inverter replacements all appear in reviews, pointing to a genuinely full-service electrical and solar operation rather than a solar-only installer. Reviews covering nearly nine years show the team working across metropolitan Adelaide as well as the Gawler region, with the Willaston base making them a practical option for both northern suburbs and Barossa-adjacent properties. Customers who received multiple competing quotes specifically note Eco Spark came out ahead on price and overall quality of engagement, not just one or the other. Tradespeople cleaning up after themselves is flagged by more than one reviewer as something that distinguishes the crew from others they've hired.
Best for: residential and commercial solar battery installations, fixing or upgrading poorly installed solar systems, full electrical fit-outs for new home and shed builds, and homeowners in the northern Adelaide metro and Gawler region wanting a single contractor for both electrical and solar work.

What areas does Eco Spark Electrical & Solar service?+
The business is based in Willaston and reviews confirm they travel into metropolitan Adelaide as well as the broader Gawler region. One review specifically mentions a job completed in Adelaide with the team based out of Willaston. If you're outside the northern suburbs or Barossa fringe, it's worth confirming your suburb with Scott directly before booking a quote.
Can Eco Spark fix a solar system that was badly installed by another company?+
Yes — this is something the team has done in practice, not just in principle. One reviewer had an interstate company arrange an installation that was completed to a poor standard, leaving a significant battery wiring problem. Sam from the Eco Spark team came out, worked through what had gone wrong, explained the issues clearly, and fixed them. If you've inherited a problematic system, this is worth raising with Scott when you call.
What do customers say about Eco Spark's pricing?+
Several reviewers mention obtaining multiple quotes before choosing Eco Spark and noting the pricing was competitive. One customer who went through a thorough quote process described Eco Spark as 'above the competition in every way,' while others specifically mention 'fantastic price' and 'very pleasing price.' Reviews don't publish specific dollar figures, so get a quote for your specific system size and confirm what's included.
Does Scott's team handle commercial electrical work as well as residential solar?+
Yes — one review covers three large commercial shed electrical fit-outs plus a full off-grid solar system, confirming the business operates beyond domestic solar installs. New home builds, shed wiring, and pergola lighting also appear in the review record. If your job is commercial or involves an off-grid setup, mention that upfront when contacting Scott so he can allocate the right crew.
Who will actually be doing the work on my property?+
Scott leads the business and handles quoting, communication, and follow-up. Named technicians who appear across multiple reviews include Troy, Riley, Charlie, Blake, and Sam — each praised for professionalism and attention to detail on-site. Sam is specifically called out for solar battery diagnostic and remediation work. Reviews consistently describe the crew as respectful of the home, punctual, and willing to clean up after themselves.
