Solar & Battery Installation Brisbane

Many older Brisbane homes have switchboards that are not compatible with modern solar inverters or battery systems. Before installation begins, we assess your existing switchboard to determine if an upgrade is required. A switchboard upgrade is a separate cost but is often necessary for safety and to meet network requirements. We carry out switchboard upgrades as part of the overall solar job where needed.

System sizing depends on your daily electricity consumption, roof orientation, available roof space, and whether you plan to add a battery or EV charger. A typical Brisbane family home will often look at a 6.6 kW to 10 kW system, but this varies significantly by property and usage. Crusader can assess your electrical setup and advise on what makes sense for your property before you commit.

Solar systems generate power that flows back through your switchboard, which can affect how safety switches and circuit breakers behave. A properly installed solar system, connected by a licensed electrician, is configured to meet AS/NZS 4777 grid connection requirements. This includes correct isolation switching and ensuring safety switches are compatible with the inverter output.

In most cases yes, but compatibility depends on your existing inverter make and model. Some inverters are battery-ready and only require a compatible battery and a software update. Others require a separate battery inverter or a hybrid inverter to replace the existing unit. We assess your current system before recommending a battery solution.

A typical residential solar installation takes one day, with battery storage adding a few hours. More complex jobs, such as those requiring a switchboard upgrade at the same time, may take a day and a half to two days. The grid connection process with Energex takes additional time after installation, typically 5 to 20 business days. Your system will be live for self-consumption during this period, but you will not receive feed-in credits until the bi-directional meter is configured.

Quality solar panels carry a product warranty of 10 to 15 years and a performance warranty of 25 to 30 years, guaranteeing output above a specified level (typically 80 to 85% of original output). Real-world degradation of well-maintained panels is typically less than 0.5% per year. Inverters have shorter warranties (typically 5 to 10 years) and are more likely to need replacement over the life of a solar system.

In most cases, no. Rooftop solar panels on residential properties in Brisbane are exempt from development approval under Queensland planning rules, provided the panels do not extend beyond the roof area and the installation complies with standards. Heritage-listed properties may have additional requirements. We advise on any specific requirements during the site assessment.

Standard grid-tied solar systems shut down automatically during a grid outage for safety reasons, which protects Energex workers. If you want solar power during a blackout, you need a system configured with backup capability, which requires a compatible hybrid inverter and a sub-board to separate backup loads.

The federal government's Small-scale Renewable Energy Scheme provides a point-of-sale discount on eligible solar installations through STCs. The value of the discount depends on your location, the system size, and the current STC price. We apply the STC discount directly to your installation quote, you do not need to claim it separately. The scheme is scheduled to phase out by 2030, so larger discounts are available sooner.
