How GJS works
Plan the cable routes. Coordinate the trades. Test before handover.
Every project runs differently. Whether it is a new home, school upgrade or commercial solar installation, the sequence changes, but the standard stays the same: careful planning, thorough testing, clear labelling and a compliant handover.
Solar and backup
Buy the system outright, or apply for a solar subscription.
GJS plans the solar, inverter, battery and DB work around the property first. From there, clients can choose the purchase route or explore a subscription application through the GJS-branded Glint portal.
The right route depends on your budget, electricity use, roof space, backup needs and the final agreement. GJS stays responsible for the electrical assessment and installation requirements.

Approved installerGeyserGecko solar water heating
Put daytime solar to work on the geyser you already own.
Water heating is one of the biggest electrical loads in many homes. GeyserGecko works with your existing geyser element, so the geyser does not need to be replaced. It uses solar power when available and switches back to grid when needed.
Three operating modes
Choose hybrid solar and grid support, PV-only solar operation, or standard AC operation when needed.
App control and timers
Set heating times and monitor geyser performance from the mobile app around the household's hot-water routine.
Installed as a complete package
GJS checks the geyser, roof, structure and cable route before installing the panels, controls and electrical connections.
