What is the future of solar energy technology? This diploma course looks beyond photovoltaic technology to the potential of solar thermal energy, bringing a fresh perspective on this renewable resource. The heat component of solar radiation can be used to generate electricity cost-effectively but that is just the beginning. We can use this vast amount of free-flowing energy for our heating requirements at home and in industries and also store this heat in various forms for later use. We can even combine solar thermal and photovoltaic technologies to provide cheap, reliable and affordable energy to the far-flung corners of the world. Surprisingly ingenious yet straightforward technology is making all this possible. The science of solar energy is still evolving but in which direction? How does it work? What is the next step? Take this course to find out the answers to these captivating questions. 

To understand how solar thermal energy can be captured, you must first understand the underlying science. The course begins by explaining the basic principles of heat transfer employed by solar collectors. You will then learn about the different types of solar thermal collectors, their construction, mode of operation, efficiency levels and challenges. Next, you will explore solar air heaters and their applications, including power generation. Moving on, the limitations of solar power mean that it may only be generated during the daytime and with clear skies so the next part of the course delves into different methods of heat storage, including the solar pond. You will also look into emerging solar technologies, including new and trendy solar cells, solar fuels and solar photovoltaic thermal technology, alongside the various new solar energy applications such as refrigeration, cooling, solar pumping and cooking. 

Solar energy is undeniably the most promising resource to ensure a sustainable future for the planet. It is not enough that we get plenty of it for free. Nor is it enough that we have invented photovoltaic systems to convert sunlight to electricity. We cannot afford to let the Sun’s heat go to waste while we continue to burn coal for our energy needs, polluting our environment. The world needs more scientists and engineers to make the most of this renewable source and you could be among those at the forefront of the sustainable energy revolution. If you have a basic knowledge of thermodynamics and high-school level mathematics, dive into this course to get a feel of the amazing technologies that are evolving around solar thermal energy and prepare yourself for a rewarding career. It's a rare opportunity, seize it now!
