This course, part of the Software Development MicroMasters Program, introduces how teams design, build, and test multi-version software systems.

You will learn software engineering principles that are applicable to the breadth of large-scale software systems. The course explores topics such as agile development, REST and Async programming, software specification, design, refactoring, information security, and more.

By the end of this course, learners will work in teams, applying an agile software development process to specify, design, and test multiple versions of complex software systems.

Learners who enroll in the Verified track will receive staff grading and increased interaction with the instructor and staff.

This course we will explore the foundations of software security. We will consider important software vulnerabilities and attacks that exploit them -- such as buffer overflows, SQL injection, and session hijacking -- and we will consider defenses that prevent or mitigate these attacks, including advanced testing and program analysis techniques. Importantly, we take a "build security in" mentality, considering techniques at each phase of the development cycle that can be used to strengthen the security of software systems.

This course on software engineering covers design and implementation of medium-scale software systems, using web applications as a platform.

Topics also include functional programming, relational databases, and security.

When writing software, destruction can be just as valuable as creation. Learn how to catch bugs and break software as you discover different testing methods that will help you build better software.

Want to gain software testing skills to start a career or are you a software developer looking to improve your unit testing skills? This course, part of the Software Testing and Verification MicroMasters program, will provide the essential skills you need for success. 

Software needs to be tested for bugs and to insure the product meets the requirements and produces the desired results. Software testing is essential to providing a quality product. 

Learn the techniques Software Testers and Quality Assurance Engineers use every day, which can be applied to any programming language and testing software.

No previous programming knowledge needed. This course will use Java and JUnit, however, for examples and assignments.

There is much more to software testing than just finding defects. Successful software and quality assurance engineers need to also manage the testing of software. 

In this course, part of the Software Testing and Verification MicroMasters program, you will learn about the management aspects of software testing. You will learn how to successfully plan, schedule, estimate and document a software testing plan.

You will learn how to analyze metrics to improve software quality and software tests.

We will also discuss software quality initiatives developed by industry experts.

No previous programming knowledge needed.

This class presents a detailed study of soil properties with emphasis on interpretation of field and laboratory test data and their use in soft-ground construction engineering. Topics to be covered include: consolidation and secondary compression; basic strength principles; stress-strain strength behavior of clays, emphasizing effects of sample disturbance, anisotropy, and strain rate; strength and compression of granular soils; and engineering properties of compacted soils. Some knowledge of field and laboratory testing is assumed for all students.

In the third edition of Solar Energy, you will learn to design a complete photovoltaic system. This course introduces the technology that converts solar energy into electricity, heat and solar fuels with a main focus on electricity generation. Photovoltaic (PV) devices are presented as advanced semiconductor devices that deliver electricity directly from sunlight. The emphasis is on understanding the working principle of a solar cell, fabrication of solar cells, PV module construction and the design of a PV system. You will gain a greater understanding of the principles of the photovoltaic conversion— the conversion of light into electricity. This course explores the advantages, limitations and challenges of different solar cell technologies, such as crystalline silicon solar cell technology, thin film solar cell technologies and the latest novel solar cell concepts as studied on lab-scale. We will discuss the specifications of solar modules and demonstrate how to design a complete solar system for any particular application.

Education Method

The class will consist of a collection of eight to twelve minute lecture videos, exercises, assignments and exams. Specified assignments and the three exams will determine the final grade. The new textbook on “Solar Energy, basics, technology and systems” from the Delft University of Technology will be available for the students on-line and free of charge. Your course staff will encourage and challenge you to learn from, and interact with, your fellow students by helping each other and sharing ideas and best practices, in the course forum. We were happy to see the incredible number of interesting student videos on solar energy systems from all over the world in the previous edition of this course. 

Professor Smets was the first ever recipient of the edX Prize for Exceptional Contributions to Online Teaching and Learning. His previous online courses attracted over 150,000 students worldwide, who were inspired to take their first steps in the transition to renewable energy.

Use the knowledge of Photovoltaic technology, systems and microgrids to design your own engineering project.

This project-based course finalizes the Solar Energy Engineering MicroMasters program and focuses on applying the knowledge you gained to a solar energy project. You will work on either your own project or on a project provided by the course team. These projects can be focused on design, analysis, monitoring or integration of any photovoltaic application.

First, you will write a short project plan describing the project and the orientation of your work. After approval, you will execute your project.

Your final product is a written paper on the results of your project. This paper will be peer reviewed and assessed by a professor. You will also defend your project in an oral presentation. You will be assessed on your ability to justify design choices, to critically analyze the performance of systems, to find creative solutions and to show the potential of your solution.

Finding a sponsor for your project within a company, institute or university is encouraged.

This is the last course of the Solar Energy Engineering MicroMasters Program designed to cover all physics and engineering aspects of photovoltaics: photovoltaic energy conversion, technologies and systems.

You can start the capstone project after completing PV1x, PV2x and PV3x. However, you will need the knowledge and skills gained in PV4x to complete the final module of this course, the oral presentation.

Note: The capstone project is only accessible for ID verified MicroMasters learners.

Photovoltaic systems are often placed into a microgrid, a local electricity distribution system that is operated in a controlled way and includes both electricity users and renewable electricity generation. This course deals with DC and AC microgrids and covers a wide range of topics, from basic definitions, through modelling and control of AC and DC microgrids to the application of adaptive protection in microgrids. You will master various concepts related to microgrid technology and implementation, such as smart grid and virtual power plant, types of distribution network, markets, control strategies and components. Among the components special attention is given to operation and control of power electronics interfaces.

You will familiarize yourself with the advantages and challenges of DC microgrids (which are still in an early stage). You will have the opportunity to master the topic of microgrids through an exercise in which you will evaluate selected pilot sites where microgrids were deployed. The evaluation will take the form of a simulation assignment and include a peer review of the results.
