Silvered glass mirrors are also less likely to tarnish over time, meaning they will look shiny and new for longer. The silvering on the back of the mirror helps to reflect more light, making it the best type of mirror to use in a PTSC because it reflects the most light. There’re 3 main types of mirrors used in parabolic trough solar collectors: Silvered glass mirror Mirrors consist of reflective layers and protective layers that protect the reflective layers from abrasion and corrosion. The solar reflector dish should be mounted to the dual-axis solar tracker so that it’s always oriented to the sun's direction.Īs mentioned above, the primary role of mirrors in a parabolic trough solar collector is to reflect the sun's radiation and focus it onto the receiver.
Reduce collisions and protect the mirrors. It’s important also that the parabolic dishes are arranged as close as possible to: Primarily, the dishes can be arranged continuously or as distinct elements (mirrors) to assume the shape of a parabolic. When it comes to the reflector dish, the arrangement is crucial. The parabolic dish reflector is the primary design component of a parabolic trough dish collector. Lastly, the receiver should also be connected to the tracking system to monitor the sun along with the dish. To reduce the mass needed to track the sun, the mass of the receiver should also be optimized. The size of the receiver should be optimized to minimize the shadowing effect. The receiver is the component-oriented at the center of the solar reflector dish to reflect and concentrate sun radiations. This steam can then be used to generate electricity or heat buildings. The fluid is heated by the sun and then used to heat water or another fluid to produce steam. Parabolic trough solar collectors consist of a curved mirror that reflects sunlight onto a tube filled with fluid. Overall, parabolic trough solar collectors offer a plethora of benefits, making them the most common type of solar thermal collectors.įrom their efficient design to their ability to generate electricity on a massive scale, it's no wonder that parabolic trough solar collectors are at the forefront of the renewable energy revolution. This not only boosts the collector's efficiency but also protects the absorber from weather elements, ensuring longevity and optimal performance. In addition to their shape, the glass reflector surrounding the trough plays a crucial role in directing more sunlight onto the absorber. Moreover, the parabolic shape focuses the radiation onto a smaller area, enhancing heat transfer and improving the efficiency of solar energy usage. The trough shape of the mirrors allows for a larger surface area to capture solar radiation compared to flat panels. 
What makes parabolic trough solar collectors so effective is their unique design. As the fluid heats up, it generates steam that powers a turbine to produce electricity, making it a popular choice for large-scale solar power plants.
These collectors consist of curved mirrors that concentrate sunlight onto a pipe filled with fluid. Parabolic trough solar collectors are an ingenious solution for capturing the sun's energy on a massive scale. What is a Parabolic Trough Solar Collector? We'll explore the advantages and disadvantages of this cutting-edge technology, how it works, and the various ways it can be applied. In this ultimate guide, we'll take you on a journey to discover the ins and outs of parabolic trough solar collectors. Parabolic trough solar collectors offer a solution to this challenge as they are the most mature and promising concentrated solar power (CSP) technology available today.
