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:
In this lecture, you will discover basics electricity concept. The concept learned are useful for the design of PV systems. We will deifine electricity, energy, power, voltage and current. We will also learn electric circuits configuration and the concept of resistance.
How is sunlight converted in electricity? In this lecture, we will get an answer to this. We will discover the three generation of PV cells and describe their performance. We will also learn the basics terms used in the PV language.
In this lecture we will list the components of off grid PV systems and learn how they work together.
Off grid PV systems rely on battery storage to supply energy when the sun is not available. In this lecture we will discover lead acid batteries, the most used batteries for solar PV applications.
Overcharging and deep discharging are the main causes of bateries premature failure. In this lecture, we will discover the two types of controller used to prevent batteries overcharging and deep discharging.
Off grid solar power system are sized based on the load to be connected. In this lecture, student will learn how assess the load.
In this lecture, we give a few tips on how to reduce the demand and therefore impact on the size of the PV system.
The PV array is responsible of generating enough energy to cover the needs of the consumers. In this we will learn how to make an accurate estimate the amount of energy a PV array should deliver.
Energy delivered by PV modules depend on several factors. In this lecture we will learn to estimate the required PV power necessary to deliver enough energy to cover consumers needs.
This lecture is about how PV modules are arranged in a system to build up the voltage or the current.
This lecture present the selection parameters of PWM and MPPT controllers.
In this lecture we will learn how batteries are arranged in a PV system to build up the voltage or the amps hour.
This lecture present inverters selection parameters.
This lecture present the three most important career path in the off grid solar industry. We will also discover what is expected from you when embracing one of those careers, and how off grid solar power systems design 101 will help you.
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).
