Our Wessun tracking concentrator for fixed tilt solar collector helps solar plants developers and operators who needs to produce thermal energy at the cheapest possible price, in order to be competitive, by reducing specific investment costs and operational risks related to freezing and overheating, as well as increasing the system energy yield and performance, specially at higher temperatures, unlike flat plat or evacuated tube collectors, without Wessun, whose performance above 80ºC is very low and are not able to avoid stagnation situation, or the Fresnel or parabolic through collectors whose investment and operational costs does not make them competitive at such low temperature levels. It also helps Energy Services Companies, District Heating Operators and large end users such as industries, to access to 100% renewable and free of particulate matter emissions cheapest energy, with stable prices along decades.
