Our Founders


Klaus Coia, Managing Director

Klaus is a licenced electrical contractor with over 30 years’ experience designing and installing solar power systems for residential, commercial and government clients. He was one of the early pioneers of the solar power industry, with a passion for renewable energy and the environment.


Karen Marks, Financial Controller & Business Development

Karen has been involved with solar power for over 25 years. Her initial passion for the industry came from her experiences living off-grid while raising a young family. She has a strong commitment to self-sufficiency and to doing something positive for the earth.

Our Showroom

Yes – our wind turbine IS generating power!

Our showroom and warehouse in Snook St, Clontarf, is energy efficient and incorporates passive lighting, passing cooling, high-efficiency lighting and automatic light sensing.

It is also fitted with PV Solar and a large Wind Turbine to generate power for our facility and to reduce our CO2 emissions.

We encourage clients to visit our showroom to see and test our different operating inverters, battery storage and solar panel systems.

“I would just like to add that we were very pleased with the wonderful service your Company gave us, and we will be recommending you to everyone we know.”

Lyn and Bill Flanagan
