Solar Parabolic Collectors

“In many places, solar heating is as economical today as power from nonrenewable sources. Nobody can embargo sunlight. No cartel controls the sun. Its energy will not run out. It will not pollute our air or poison our waters. It is free from stench and smog. The sun’s power needs only to be collected, stored, and used.” President Jimmy Carter, May 3, 1978 – Sun Day “Steam is the alternative electricity” – Bill Petitjean, P.E.

The 60120 is a parabolic trough linear solar concentrator for industrial and commercial applications for providing heat up to 400°F. Each module of four troughs track the movement of the sun through the day, capturing the direct solar radiation. The solar energy landing on the surface of the parabola is reflected and concentrated to the focal axis where the receiver tube is mounted.

Why is ours better?

VMC’s trough is specifically designed for flat-packing to minimize transport volume. It uses lightweight materials to facilitate low shipping costs, mounting on existing structures, and assembly at the installation site. It is easy to learn how to assemble our troughs which provide job opportunities for local labor as well as further cost savings. At the end of the designed service life, the aluminum frame and hardware are highly recyclable and the flat trough bodies and mirrors may serve for roofing of shelters.
