David Wilson is the founder of Green Frog Systems and a long time innovator in off-grid solar lighting and energy storage. With a background in engineering solar lighting systems for some of Australia’s harshest environments, David has spent over a decade developing practical, field tested solutions for remote and resource constrained infrastructure. His work led naturally into off-grid energy storage, helping industry and government deploy standalone systems where traditional power access is limited, expensive or unreliable. David is known for translating technical innovation into durable, deployable systems—bridging the gap between sustainability targets and real world operational needs across mining, transport, and local government.
