The paper focuses on the technical problems and the possible solutions that has been achieved or under investigation to overcome the challenges in the solar technologies by the author and his research team in the solar thermal advanced research centre in Universiti Teknologi PETRONAS. Those achievements are part of the commitments of this solar research team for going heavily towards solar energization in the globe. © 2019 Bangladesh University of Engineering and Technology.
