Engr. Solomon Uche
Technical Administrator, RETTI Solar Panel Factory
Solomon Uche's Profile
I'm an expert solar panel designer and builder. My interest in electrical engineering and handson coupling of products started at a very young age with the love to design hand tools which prompted me to take my passion higher to study Electrical and Electronic Engineering.
My work experience has prepared me for a career as a solar technical project designer and educator. My rich experience as a site installer, solar energy facilitator at Abia State University Uturu Center for Entrepreneurship gave me a deep understanding of student management and market opportunities for solar power as a business. Having worked with ETPM Nigeria as a Battery Regeneration Technician, High Tech Center for Nigerian Women & Youths (NGO), SunKing solar and as a sales expert with Fenix International, My understanding of the solar components and opportunities for business has improved, giving me a first hand knowledge of teaching about this.
I was part of the pioneering team who set up the Physics and Solar Energy Department of the Gateway Polytechnic, Ogun State and was the expert who trained their trainers.
I currently works as a technical administrator for the Renewable Energy Technology Training Institute’s solar panel assembly factory. I also teach same at the institute.
