Tandem Energy
Helped a client find and apply for grant funding — and talked them out of work they didn't need.
Both reviewers name specific team members — Rachel and Tom — which tends to signal a small, consistent crew rather than a revolving door of subcontractors. If you're considering solar in the Gawler area and want a consultative approach rather than a hard sell, it's worth getting a quote and asking them directly what government incentives you might qualify for.

About Tandem Energy
Rachel and Tom are the two names customers mention by name at Tandem Energy — Rachel appears to handle client-facing coordination while Tom brings the technical know-how, and reviewers describe the pair as approachable people who genuinely understand solar and energy systems. One standout detail from a recent project: the team identified a path to grant funding the homeowner hadn't pursued, then helped them successfully apply — a level of advisory work that goes beyond a standard install quote. With roughly 11 years operating out of Gawler, Tandem sits in a region where energy costs and rural grid reliability make solar a practical investment rather than a lifestyle choice, and that context appears to shape how they approach jobs. Rather than pushing unnecessary procedures, they've been noted for trimming scope where possible to save clients money — a useful trait when solar quotes can vary wildly depending on who's assessing your roof. The business appears well-suited to homeowners who want a consultative process, not just a panel-and-inverter transaction.
Best for: homeowners wanting grant and rebate guidance alongside their install, clients who prefer a consultative low-pressure process, and Gawler-area properties looking for an experienced local solar operator.

What areas does Tandem Energy service?+
Tandem Energy is based in Gawler, SA, which positions them well to service the Barossa Valley region, northern Adelaide suburbs, and surrounding rural areas. Reviews don't specify exact service boundaries, so if you're outside the immediate Gawler area, it's worth calling to confirm they cover your postcode. Businesses operating from Gawler commonly service a broad radius given the regional setting.
Does Tandem Energy help with solar rebates and government grants?+
Yes — one reviewer specifically credits the Tandem team with helping them identify and successfully apply for grant money on their project, which resulted in meaningful cost savings. This advisory role appears to be part of how they approach jobs, rather than something you'd need to ask for separately. If you're unsure what state or federal incentives you qualify for, it's a good question to raise when you first contact them.
Who are the key people at Tandem Energy?+
Reviewers mention Rachel and Tom by name — Rachel appears to handle client communication and coordination, while Tom is described as someone who knows their stuff technically. Both are described as easy-going and approachable, which suggests a small team where you're likely dealing with the same people from quote through to install. With only 2 reviews available, we can't say much more beyond what customers have directly shared.
Is Tandem Energy likely to recommend work I don't actually need?+
Based on the available reviews, the opposite seems to be the case — one customer specifically notes the team saved them money by avoiding unnecessary procedures. That said, with only 2 reviews to draw from, this is a small sample and we'd encourage you to get a detailed written quote and ask them to walk you through each line item. A reputable solar installer should always be able to explain exactly why each component is recommended.
How long has Tandem Energy been operating?+
Tandem Energy has been active for approximately 11 years, which is a reasonable tenure in the solar industry — particularly given how many installers entered and exited the market during the early solar boom. Longevity in this category matters because it suggests the business has weathered changes in rebate structures, panel technology, and installer certification requirements. It also means they're more likely to still be around if you need warranty support down the track.
