My experience at RETTI has been a very enlightening experience. I would've never believed I could become an expert in Solar photovoltaic installation and design in such a short amount of time. Our training has been very practical and efficient, the environment was very conducive, our instructor was so apparent that he could turn a ten year old into a solar engineer in less than a month if he wanted to, and the huge support for the female students here was really beautiful to see. RETTI is by all standards (in and out of Nigeria) one of the best educational institutions you could affiliate yourself with. I am very grateful for this opportunity and will be recommending it to anyone who is interested in making a change in their lives and the world at large via the potential of Solar Energy.
