Must know, must do, must teach

The principle behind the book: know the technology and its requirements, apply that knowledge with discipline, and share the experience so the next generation can do better.

Foreword

Tan Sri Dr Lim Wee Chai

I am pleased to see the publication of the C&I Rooftop Solar Engineering Handbook 2026. By bringing together technical knowledge, practical experience, engineering considerations and good practices, this handbook can serve as a useful reference for professionals and practitioners involved in the development of commercial and industrial rooftop solar projects.

The transition towards renewable energy is no longer an aspiration. It is becoming an important part of how businesses operate, manage costs and build a more sustainable future.
