Cairns Toy Library Manoora’s 6.64kW Trina Solar Panels with Sungrow Inverter

Cairns Toy Library in Manoora stands as a testament to community-driven sustainable initiatives. A non-profit, volunteer-operated organization, the library not only offers an array of toys suitable for children aged 0–8 but also champions the reduction of waste and environmental footprint. By joining, members not only save money and declutter their homes but also engage with the local community, meeting other families and accessing exclusive party hire packs. Yet, the very essence of this community-centered organisation is its dependency on local support to sustain its operations, manage electricity costs, and ensure its doors remain open, inviting more families into its fold.

The Challenge!
Access the Cairns Regional Council Grant to Install Solar Panels and Reduce Costs

Cairns Toy Library, a not-for-profit institution, faces the pressing challenge of sustaining its operations amidst limited funding and resources. Central to its financial burden is its monthly energy bill, which has historically been $50. However, come July 2023, this figure is slated to surge by a steep 35%. Given the library's intrinsic reliance on community backing and donations to serve the children and families of Cairns, this escalation in energy costs poses a significant hurdle.

Our high-efficiency PV cells are suitable for a broad range of module applications including private rooftop installations, commercial and industrial rooftop installations, remote power generators and large-scale power plants on the ground and on the water.

In an ambitious bid to not only neutralize this looming cost but also turn it into a revenue stream, Cairns Toy Library is setting its sights on solar energy. The vision is clear: deploy a solar power system that not only offsets their monthly bill but also yields surplus energy. This surplus, when sold back, can provide a credit from the energy retailer. The financial gains from this credit can then be channeled directly back into enriching the library's offerings and services.

To make this transition smooth and trustworthy, Cairns Toy Library is seeking to leverage local incentives. They are eyeing the Cairns Region Council's business sustainability grant, a local solar incentive that can cushion the financial implications of this green transition.

Behind this initiative is the trusted guidance and expertise of Brenton Hielscher, the owner of Hielscher Electrical, a frontrunner in the solar provider domain. With his reputation, Cairns Toy Library aims to harness solar energy efficiently and economically, turning a challenge into an opportunity.
