Lars Koerner, RENAC
Current position:
Lars Koerner joined Renewables Academy (RENAC) AG in May 2014 as Project Director. He coordinates and conducts training programs at Renewables Academy (RENAC) AG mainly in the field of solar energy systems. Off-grid systems and PV-Diesel-Hybrid mini-grids for rural electrification or industrial applications are his special interest.

Professional experience:
Before joining RENAC Lars gained seven years of experience as project engineer and senior product manager at SolarWorld AG where he also managed several rural electrification projects. His experience in the area of solar energy spans further through his work at the German Aerospace Center (DLR) in Almeria, Spain and Fraunhofer ISE in Freiburg, Germany. He is an expert in sizing and simulation of solar energy systems and the co-author on off-grid systems in Earthscan’s 3rd edition of “Planning and Installing Photovoltaic Systems”.

Lars holds an engineering diploma in Environmental Engineering / Renewable Energies and is also a state-licensed electrician.
Frank Jackson, RENAC
Current position:
Currently Frank runs a range of courses for people who are getting involved in the renewable energy industry and more specialised courses for solar electricity.

Professional experience:
Frank Jackson is an expert solar photovoltaic trainer and has been involved in the solar energy industry since the early 1990s, running courses and seminars, designing and installing systems, and more recently active in publishing. He has worked in the UK, France, Germany, Spain, Kenya, Tanzania and Somalia. Besides training activities, he has also designed and installed numerous photovoltaic systems (both off-grid and grid-tied).

Frank Jackson studied 1992 Photovoltaics and Development at the University of East London, and Electrical Installation Competences at the City & Guilds London Institute, London & Wales.
Gerhard Rauch, RENAC
Current position:
Gerhard Rauch has been a member of the RENAC since October 2018. As a Project Manager in the Solar Department he is responsible for the realisation of capacity building solar photovoltaic projects around the world. He is currently involved in the “Trainings on Rooftop Photovoltaic Systems in India – TROPHI” which targets various stakeholders critical to the realisation of India’s National Solar Mission. He is also responsible for the RENAC Training Centre, where he, and other trainers, incorporate practical demonstrations and exercises into their seminars about renewable energies and energy efficiency.

Mr. Rauch holds a Masters in Aeronautics and Astronautics Engineering, has experience as a project engineer in industrial automation and as a secondary school science teacher in the United Kingdom.


"ne of the best trainings that I have attended. The program, the instructors and the atmosphere were great. It was a great experience for me. Thank you."
Bassem Chalak, Lebanon, Grid-connected and Off-grid Photovoltaics, 2015

"The Grid Connected and Off-Grid Solar PV training has enhanced my technical knowledge of solar and tremendously increased my performance as a renewable energy consultant.
Segun Adaju, Nigeria, Grid-connected and Off-grid Photovoltaics, 2015
