Abacus Energy
Tommy and the Abacus team solve the jobs other installers wouldn’t touch.
The theme that matters is not just clean solar installs but a team that works out difficult or custom jobs. Customers mention Tommy working through engineer requirements on insulated roofs, designing a solar array for wildlife research, and supporting an off-grid system for nine years after installation. That points to someone who stays on the job after the panels are up. The office and team get repeated praise for showing up when promised and keeping customers informed. If you have a straight forward solar quote, you will probably be fine driving it yourself. If you want panel placement, cable runs, or battery setup to be thought through carefully, ask for Tommy so you know who is making the call on site.

About Abacus Energy
Tommy runs the show, and reviewers keep describing him as a problem-solver willing to take on jobs with extra engineering requirements. One job needed custom fixings on insulated roof panels, and Tommy went beyond what the engineer asked. That can-do attitude shows up again in a custom solar array he designed for an animal tracking system. Mostly residential solar and battery work, with a steady side of off-grid and general electrical jobs. The office side gets nearly as much praise as the tradies, with several customers saying communication from quote to handover kept them in the loop. Steven and Angela appear connected to the business too, and one long-term family customer said they supported his off-grid system for nine years, including helping after lightning strikes. Expect clear explanations on how the system works and what to do next. A good fit for homeowners who want someone to tailor the system to the site instead of just banging panels on. Also worth knowing for people doing new builds or moving into a place with both solar and electrical needs.
Best for: homeowners with tricky roof or engineering requirements, off-grid and battery system projects, and locals who want solar and general electrical work from one crew.

Does Abacus Energy do more than basic solar installs?+
Yes. Alongside standard rooftop solar, several reviews mention battery setups and off-grid systems. One customer said they installed an off-grid solar system and completed all the internal electrical work too. That suggests they can handle homes with broader electrical needs, not just panel installation.
Who should I ask for if I want a complex or custom job?+
Tommy is the name that comes up repeatedly for tricky work. One review described him going beyond engineer requirements on a hard roof fixing. Another mentioned he designed a custom array for wildlife research equipment. If your place has quirks, asking for Tommy is a practical starting point.
Do they communicate well during the job?+
Customers consistently say yes. Several reviews mention being kept informed from quote to completion. One even said the technician returned after 4.30pm to walk them through the system once they were home from work.
Are they worth considering for battery or off-grid systems?+
The reviews suggest real experience here. A customer described an off-grid system still going strong after nine years, and the team helped them after lightning strike issues. That long-term relationship is useful evidence if you are planning a battery or standalone setup.
