High-performance slewing drives, L-type swivel bearings, and cross-roller components engineered to sustain the extreme loads of CSP heliostats and thermal receiver systems.
As the global energy transition shifts away from fossil fuels, the inherent intermittency of solar photovoltaic (PV) and wind power has emerged as a significant challenge for grid stability. Concentrated Solar Power (CSP) integrated with Thermal Energy Storage (TES) offers a commercially viable, utility-scale solution capable of providing reliable, dispatchable, and continuous baseload power, even during periods of zero solar irradiance or overnight. Unlike battery energy storage systems (BESS), which face technical limitations related to degradation and limited storage duration, molten-salt-based thermal energy storage systems can store thermal energy for up to 15 hours or more with minimal degradation over a 25-to-30-year operational lifespan.
The mechanical core of any utility-scale CSP facility (whether Utilizing Parabolic Troughs, Solar Towers, or Linear Fresnel Reflectors) resides within its solar tracking system. Heliostats and parabolic collector loops must follow the sun's trajectory with sub-milliradian precision to maximize heat concentration onto receivers. A failure in tracking precision directly reduces the operating temperature of the heat transfer fluid (HTF), undermining the entire efficiency of the thermal storage loop.
As an industry-leading transmission solutions provider, Jiangsu Manchen Transmission Technology Co., Ltd. manufactures high-reliability slewing drives, horizontal rotary drives, and customized large-diameter slewing bearings designed specifically to meet the high wind load and high overturning moment requirements of global CSP solar tracking arrays.
The CSP and Thermal Storage sector is experiencing rapid technological evolution. The industry is moving from first-generation synthetic oil-based parabolic trough systems towards higher-temperature molten-salt solar tower configurations. High temperatures (often exceeding 565°C) directly translate into higher thermodynamic efficiency for steam turbines or advanced supercritical carbon dioxide (s-CO2) power cycles.
Modern solar tower projects utilize tens of thousands of individual dual-axis tracking mirrors (heliostats). Each heliostat requires a dedicated elevation and azimuth slewing drive designed to withstand high winds while maintaining absolute precision to focus sunlight onto the central tower receiver.
Wind buffeting on heliostats induces severe gear fatigue and positioning drift. Our research and development efforts prioritize zero-backlash slewing designs and highly integrated internal gear tracking mechanisms to protect sensitive mechanical gear teeth from premature wear.
Next-generation CSP projects incorporate smart sensors within slewing drives to monitor temperature, vibration, and backlash profiles. This data enables predictive maintenance protocols, reducing operational costs and preventing catastrophic failures during peak solar hours.
