Sunshine Coast property considerations
- Coastal properties benefit from corrosion-resistant mounting and componentry
- Larger rural-residential blocks further inland often support bigger arrays
- Strong year-round solar irradiance across the region supports good self-consumption
- Holiday and rental properties often benefit from battery storage to manage variable occupancy
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 I need council approval to install solar on the Sunshine Coast?
Most residential solar installations don't require council approval. Grid connection does need approval from Energex, which we manage on your behalf as part of the installation.
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.
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.
Do you service acreage and rural-residential properties?
Yes, including larger blocks further inland from the coast where bigger arrays and three-phase supply are common.
How long does a typical installation take?
Most residential solar and battery installations are completed within a day, with grid connection approval following separately through Energex.
