Goliath Solar & Electrical
Customers regularly return years later — for batteries, warranty claims, and advice — because Tom Morgan stays reachable long after install.
Tom Morgan is the central figure in most positive experiences and is reachable directly rather than through a call centre. Ben and Daniel handle much of the initial quoting and are both noted for honesty that costs them the sale — multiple reviews describe Goliath declining jobs they couldn't do well rather than pushing ahead. Goliath is not the cheapest option in the Adelaide market by their own customers' admission, so if price is your primary filter, ask them to explain what you get for the premium before deciding.

About Goliath Solar & Electrical
Goliath Solar & Electrical has been operating for roughly 14 years and is led by Tom Morgan, who handles consultations, system design, and post-installation support — reviewers repeatedly single him out for explaining complex solar and battery options in plain language without any sales pressure. Ben and Daniel round out the sales and advice team: Ben is praised for patience with indecisive customers and willingness to re-quote different configurations, while Daniel is noted for honest upfront advice, including telling prospective customers when Goliath isn't the right fit for their roof type rather than overpromising. On the tools, the installation crews — including named members Sam, Jordan, Josh, and Louis — draw consistent praise for punctuality, clean worksites, and professional cable management. The business focuses exclusively on residential solar and battery storage, with particular depth in high-end battery systems: Tesla Powerwall 2 and 3, Sigenergy, and SolarEdge batteries all appear across multiple reviews, and they've handled everything from standard 6.6kW rooftop systems to large 76-panel arrays and new-build pre-cable work. What sets Goliath apart operationally is their pre-sale roof analysis — several customers note that Goliath identified shading issues or roof compatibility problems that competing installers had missed or ignored — and their ongoing post-installation engagement, which includes firmware update guidance, feed-in tariff recommendations, and proactive performance monitoring years after install.
Best for: residential homeowners wanting a thorough pre-sale system assessment rather than a fast quote, customers adding battery storage (Powerwall, Sigenergy, or SolarEdge) to an existing solar setup, and new build projects requiring solar pre-cabling coordinated around construction stages.

Who will I actually deal with at Goliath Solar & Electrical?+
Most customers deal with Tom Morgan for consultations, system design, and post-installation support — he's the name that appears most frequently across reviews and is noted for being reachable directly rather than through a call centre. Ben handles a significant portion of the quoting process and is praised for patience with customers who need multiple re-quotes across different configurations. Daniel also manages quotes and initial consultations, and is noted specifically for honesty about what Goliath can and can't install. On installation day, crews including Sam, Jordan, Josh, and Louis handle the physical work.
Does Goliath Solar install battery storage, and which brands do they work with?+
Battery storage is a core part of what Goliath does, not an add-on. Across the reviews we analysed, customers mention installations of Tesla Powerwall 2, Tesla Powerwall 3, Sigenergy batteries, and SolarEdge batteries — often as standalone upgrades to existing solar systems rather than only as part of new installs. Several reviewers returned to Goliath specifically for a battery after having solar installed years earlier. Tom Morgan is noted for handling warranty negotiations with manufacturers, including in one case arranging an upgrade from a Powerwall 2 to a Powerwall 3 under warranty.
What do customers say about Goliath's pricing compared to other Adelaide solar installers?+
Goliath is consistently described as competitive but not the cheapest option — multiple reviewers explicitly note they were not the lowest quote but chose Goliath for the quality of their pre-sale analysis and the confidence that the system would perform as promised. Some customers with large systems (60+ panels, 13kW+ setups) still describe the pricing as excellent for what they received. If budget is your primary constraint, it's worth asking them to explain what's included in their quote compared to lower-cost alternatives before making a final decision.
Will Goliath take on my job if I have a tricky roof or an unusual install?+
Goliath is transparent about the work they won't do — multiple reviews describe them declining jobs on terracotta tile roofs due to cracking risk, and declining installs more than a few hours from Adelaide. In both cases, the customers reviewing the experience were positive about how Goliath handled the refusal, noting they were given genuine advice about what to look for when approaching other installers. For new builds, reviews confirm they handle pre-cabling at the right construction stages. For complex or multi-phase systems, reviews mention 3-phase installations and coordination with SAPN for grid connection upgrades.
How does Goliath handle issues after installation?+
Post-install support is one of the most frequently mentioned positives across the 50 reviews we analysed — customers describe receiving follow-up calls within hours of installation, ongoing support for firmware updates, help navigating SAPN grid issues, and proactive performance monitoring years after the initial install. One reviewer noted that an email about a system fault was answered within the same day. The one area where post-install support drew a mixed review involved a third-party inverter manufacturer's response time during a warranty replacement — Goliath managed the process but was constrained by the manufacturer's timeline, which extended the outage period.
