Parabolic Solar Troughs

The Parabolic Solar Trough, Heats up Water (fluid) to 400 degree C.

Resulting in safe water to drink and or to make steam for electricity.

Parabolic solar trough collects solar energy up to 10 hours per day compared to a 6 hour day with regular flat plate collectors

Made with mirrored surfaces curved in a linearly extended parabolic shape. A receiver tube running in the center and the length of the trough is the focus point on which the sun generates solar energy. Water is pumped through the receiver tube and is heated as it passes through the receiver tube. The heat is used to create steam, which powers engines, produces energy or simply to heat a home. 

The trough has a mechanical slewing drive with a electronic tracker that uses a mathematical algorithm to track the sun. The tracker is oriented north to south and tracks the sun east to west. These collectors can collect solar energy up to 10 hours per day compared to a 6 hour day with regular flat plate collectors. Shown in the picture above is a one 61.87 sq. ft. section of our parabolic solar trough. Several sections are ganged together to make a large parabolic solar water heater / steam heating system or solar powered heater. Eight sections make up a 495 sq. ft. solar parabolic trough.

The Parabolic Solar Trough operates at about 75% efficiency and at 495 square foot, collect approximately 270 kWh / 10 hours on a clear day.

In a more elaborate set up our parabolic solar trough can be used to make higher pressure steam. As a result can drive a heat engine (steam engine or turbine) to make electricity or directly into a mechanical drive.

How to form a perfect strong durable solar trough using just your hands. This was designed to ship flat, 100 of these equals only 4 inches. This parabolic trough is sold as a kit for approx $250 not including packing and shipping. Different reflective materials can be used. Such as Mylar, vinyl, reflective aluminum with a PVD protective coating. Our email is envsolar@comcast.net

 

 

Efficiency

The parabolic solar trough operates at about 75% efficiency, and at 495 square foot can collect approximately 270 kWh / 10 hours on a clear day.

This solar energy is used to do work such as heat water to higher temperatures of 212°F (100° C), killing all bacteria in the water making it safe to drink. In many 3rd world countries safe clean drink water is a problem. Note: this system will not remove any chemicals in the water. If the water has heavy sediments a sediment filter should be used in conjunction with our Parabolic trough water heater / steam generator.

The solar parabolic trough also creates steam to be used for cooking in a large pressure cooker. Cooking with steam takes 1/3 of the time as regular cooking. The steam can be also used in a canning process for a community.

During harvest time much of the abundance of produce in the fields spoils. The parabolic trough thermal water heater will  sterilize the jars, blanch the fruits or vegetables, then use the 240°F – 15 PSI steam for the canning process.

Features

Solar trough creates solar energy, solar hot water, steam cooker and pressure a steam engine.

This solar trough tracks the sun using a mathematical algorithm and will not chase shadows from clouds.

Solar trough tracker

Heavy duty, light-weight and durable. Patented parabolic solar trough reflectors, has the latest technology. CNC precision is used in the process of making our parabolic troughs. A precision made parabolic trough focuses more solar on a receiver tube collector resulting in creating more solar energy.
