Gallery: SkyFuel’s SkyTrough is World’s Most Efficient Solar Concentrat...


When it comes to producing solar power, efficiency is the key – efficiency of the panels, efficiency of the system’s collectors and, according to SkyFuel, efficiency of the solar concentrator technology. Solar concentrators are increasingly being used in the industry, due to their efficiency in providing cheap solar energy. By harnessing the sun’s energy, a solar concentrator can provide the necessary heat for dozens of homes and thus save electricity. As such, the systems are more efficient than regular solar generators as captured power is not just converted into electricity. But according to SkyFuel, a U.S.-based company, their SkyTrough solar concentrator technology has a thermal efficiency of 73% at 350˚C (662˚F). More than just a shallow claim, their statement has been confirmed by the National Renewable Energy Laboratory (NREL), which has certified the SkyTrough solar concentrator technology to have the highest efficiency in its class!

    We need to import curved mirrors & recivers for parabolic trouph solar cocentrator

    If you read the original press release on our website (, you will see that, indeed, the thermal efficiency of the collector is 73% at 350 Celsius. A white paper describing the test is available for download at

    \”a thermal efficiency of 350˚C (662 ˚F), which exceeds the standard by 73%\”
    This line does not make sense. Thermal Efficiency is unitless. Later you say \”thermal-to-electricity loss is only 27%\”
    This suggests you mean thermal efficiency is 73%. This sounds rather high. I think the most efficient generators are only 60% efficient, since Solar Collectors must incorporate such generators they cannot be more efficient than this. I could be wrong. Please clarify.
