HomeSolar 2025

solar system upgrade project 2025

A grant-funded project to: reduce our electricity costs, to allow our pottery kilns to run overnight, so as to time-shift noxious fumes away from when people are participating in other Mission Arts activities, while also enabling all our operations, including kiln runs, to continue uninterrupted, even in the face of extended mains outages. The project was prioritized by the members at the 2024 AGM.

Project scope: to upgrade (replace) our existing 3kW solar panels with new high-efficiency 26.5kW of panels, a new Sungrow 25kW 3phase 'battery-capable' inverter and a large 'kiln-scale' 70kWh battery, and to connect The Cottage's power to the new system as well.

typical kiln run

Depending on the actual kiln cycle, our battery will typically also power much of the remainder of our background overnight power requirements:

extended cloud cover

At the end of December 2025, the Mission Beach area received over 1000m of rain continuously over a 4day period.
Our solar panels and battery successfully delivered all our requirements, without drawing any grid power.
At its lowest point, the battery still had 20% of its capacity remaining, and recovered quickly to 100% over the following day:
