These advanced systems are particularly beneficial for homes with solar batteries, offering insights into charge levels, battery health, and discharge patterns to optimise battery longevity.

Retrofit Systems

For existing solar panel installation Perth systems without built-in monitoring, retrofit systems provide a viable solution. These can be added to your current setup to provide data on power output, voltage, current, and temperature, effectively upgrading older installations with modern monitoring capabilities.

Practical Application: A Perth Homeowner's Journey with Solar Monitoring

Imagine the Smith family in Cottesloe, Perth, who installed a 6.6 kW solar system on their home in late 2025. They opted for a system with integrated inverter monitoring, alongside an additional consumption meter.

Initially, the monitoring app confirmed their system was generating an average of 28-32 kWh per day, significantly reducing their daytime electricity reliance. However, after a few months, they noticed a slight but consistent dip in production, showing 25-28 kWh daily. Their solar monitoring system immediately flagged this as a potential underperformance. Upon inspection, they discovered a section of panels was partially shaded by newly grown foliage on a neighbour's tree, a factor they hadn't initially accounted for.

Thanks to the early alert from their solar monitoring system, they were able to trim the offending branches, restoring their system to optimal output. Furthermore, by observing their consumption patterns through the app, they realised their old pool pump was a major energy hog in the late afternoon. They adjusted their timer to run the pump mid-morning, coinciding with peak solar production, effectively using their own generated electricity rather than drawing from the grid at higher rates. This simple adjustment, empowered by their monitoring data, further maximised their savings and underscored the value of their solar panel installation Perth.

Current Solar Rebates and Tariffs in Perth (January 2026)

Investing in a solar panel installation Perth remains attractive due to ongoing government incentives and the long-term savings on electricity bills.
