Requirements
  • Students don’t need prior solar PV knowledge to take this course: all the basics concepts will be explained and, we will also use examples to make sure students understand.
Description

The goal of this course is to provide a solid understanding of the fundamental concepts necessary to design a stand-alone solar power system. Students will learn to perform application-based load analysis, how to size PV array and configure battery banks to meet energy requirements; students will also learn controllers and inverters design criteria.

The class will consist of a collection of three to five minute lecture videos and exercises. The instructor encourage and challenge students to learn from each other, and interact by helping each other and sharing ideas and best practices, in the course forum.

The course is structured in four section:

  • Stand-alone solar PV basics
  • Load assesment
  • Stand alone PV systems design
  • Conclusion
This course is ideal for those seeking to enter the off grid solar PV industry and, for those already in the industry but seeking to strengthen their design skills.
Who is the target audience?
  • This course teaches the theory necessary in order to design an off grid photovoltaic (PV) system. It is the ideal course for those seeking to enter the off grid solar PV industry and, for those already in the industry but seeking to strengthen their design skills. Even if the course is particularly indicated for off grid solar PV installers, this course is not a PV systems installation course.

Off Grid Energy Solutions Professional

Mathy is the founder of Energy One Africa, a company founded with the goal of giving energy access to underserved low income consumers via pay-as-you-go. Energy One Africa's subscribers own a solar lamp after its full payment through small increments equivalent to their current kerosene lighting expense. Energy One Africa plans to reach 33000 subscribers in the rural Democratic Republic of Congo (DRC) between 2017 and 2019. He is also an IEEE  Smart Village Ambassador, D-Prize winner and Tony Elumelu Entrepreneur

For ten years Mathy worked tirelessly to improve energy access for communities in Burundi, South Sudan, Rwanda and DR Congo. As both a challenge and an opportunity, Mathy demonstrated skills beyond his technical field in terms of project management, and the situation afforded him a chance to train and to efficiently build capacities in those he served. He takes a kin interest in understanding the real need of the communities he serves, especially their vital need for affordable energy. He believes that Energy Solution is the path to a better future for Off-grid communities.

His unique set of skills makes him a valuable asset for all his employers. In 2010, while employed by UNITECH in Burundi, he designed and conducted the solar electrification of Gasorwe and Bwagiriza refugee camps. The project consisted in designing and building 60 public lighting points, electrifying 12 classrooms, offices, and ONPRA residences (Burundian authority in charge of refugee affairs).
