When a short course is not enough and you want the full picture, the Diploma in Solar Energy is the free option that goes deep. It runs about 6 to 10 hours at the advanced level, costs nothing to take, and ends with a diploma rather than a certificate.
The course examines solar energy as a primary renewable source and asks the big question: can it meet the world's power demands? You learn to compute solar energy quantities and compare them against real consumption, define the electromagnetic spectrum and how energy is distributed across it, and understand solar concentrators, including the difference between imaging and non-imaging types, plus solar tracking and harvesting methods.
Fair warning: this is an advanced, concept-heavy course, and it rewards a reader who already has the basics. If you are just starting, the beginner solar course on our Free Shelf is the better first step. But if you want to truly understand how we capture the sun, and you want a diploma to show for the effort, this delivers both.
What you will learn
- Whether solar can meet global energy demand, with the math to judge
- The electromagnetic spectrum and how solar energy is distributed
- Imaging and non-imaging solar concentrators
- Solar tracking and harvesting methods
What the diploma covers
- Weigh the resource: compute solar quantities and compare them to consumption.
- Understand the light: the electromagnetic spectrum and its wavelength distribution.
- Concentrate it: imaging versus non-imaging concentrators and why it matters.
- Harvest it: solar tracking and the methods that capture the most power.
The lessons are free to finish. When you complete the course, a diploma is available that you can add to your resume or LinkedIn, and a diploma in a renewable field can help you land work or support a raise where you already are. You are never required to buy it to finish the course.
Depth is its own kind of security. If you want to understand solar the way a professional does, this diploma is where that understanding comes together.
