About us

Welcome! We’re a not-for-profit volunteer association in the Northern Beaches and North Shore helping homes, businesses and schools to get solar, electrify and reach net zero. We’re part of Beyond Zero Emissions‘ national zero carbon community network. We focus on practical projects that accelerate our transition to net zero emissions.


To create a sustainable community for current and future generations.


To develop new programs and champion existing initiatives to help our community and homes, businesses and schools get solar, electrify and rapidly transition to net zero emissions.

Our activities

We create high-quality resources and programs to help homes, businesses and schools rapidly reach net zero. We provide online and in person education sessions, displays and events to promote climate solutions. We advocate for, implement and support practical projects. We draw on the diverse strengths of our community and ensure best outcomes by collaborating with business, not-for-profits and all levels of government. We welcome collaborations!

Sunny and Share

Our activities are funded by volunteer donations and grants. As a thank you, our Solar My House partner and our electricity retailer of choice contribute to support our work and or Community Giving Fund. The Fund is used to install solar systems for local charities and not-for-profits. Lowering their power bills frees up funds for their core programs. We’ve installed solar on one local charity, with our second project soon.
