System sizing and grid approval, handled for you.
Design & sizing
System size is calculated from your electricity bill and consumption pattern, including single and three-phase properties.
Battery integration
Battery storage is sized against your evening and overnight usage, whether it’s a new system or added to existing solar.
Grid connection
We manage the Energex network application and approval process as part of every installation, so the system is compliant from day one.
What clients say
“I highly recommend TSG Electrical. We live in Brisbane and TSG have installed an EV charger for us — Jeremy, Leigh & Kieran were all delightful to deal with, good communicators, explaining the equipment well and ensuring it worked.”
“I used TSG Electrical to inspect, quote and rectify my faulty solar system — a damaged panel on my roof. Allan rectified the problem and had me back on the grid within 1.5 hrs. Fantastic customer service — he took the time to show and explain what was going on.”
“TSG were super friendly, authentically desiring to help resolve the issue — helpful, punctual and organised, clearly quoted, completely transparent. Informed me of the best repair method and why, for safety and compliance. Highly recommended without hesitation.”
Frequently asked questions
Do you install solar for commercial and industrial properties in Brisbane?
Yes — we design and install commercial solar and battery systems for businesses across Brisbane's northern corridor, sized against demand charges and actual site usage.
What's involved in a three-phase solar installation?
Three-phase properties need an inverter and system design matched to balanced loading across all three phases. We assess your switchboard and supply as part of the design process.
Can I add a battery to my existing solar system?
Yes — battery retrofits to existing solar are common. We assess your existing inverter and system to confirm compatibility and the right battery size for your usage.
What size solar system do I need?
It depends on your electricity usage, not a fixed rule of thumb. We size systems from your actual bill and consumption pattern — you can also get an instant estimate with our solar calculator before speaking with us.
How much can solar and battery reduce a business's demand charges?
It depends on your load profile and peak demand periods. We review your actual usage data as part of a commercial assessment before recommending a system size.
