Solar power is the perfect power source for the Rangitoto lighthouse.

Offering numerous advantages, making it an ideal and efficient energy source for lighthouses.

1. Remote location suitability: Like many lighthouses, the Rangitoto Lighthouse is situated in a remote and relatively inaccessible area where the grid connection is challenging or costly. Solar panels provide an independent power source, eliminating the need for extensive power lines or infrastructure.
2. Reliability: Solar power is reliable and consistent, especially in areas with ample sunlight.  This reliability is crucial for lighthouses as they need continuous and uninterrupted power to operate 24/7, ensuring the safety of maritime navigation.
3. Low Maintenance: Regular cleaning of solar panels and occasional checks on the system’s components are usually sufficient, reducing operational costs and the need for constant supervision.
4. Environmentally Friendly: Solar energy is a clean and renewable source, producing no greenhouse gas emissions or pollution during operation. Utilising solar power for lighthouses aligns with sustainability goals and reduces the environmental impact compared to traditional fuel-based alternatives.
5. Cost-effectiveness: The size of solar panels needed to power a lighthouse such as Rangitoto is small; therefore, the panels cost minimally. A 100W Solar Panel costs just $139.99. The long-term operational cost is significantly lower than conventional energy sources.  Solar energy is essentially free once the infrastructure is in place.
