Concentrating solar power (CSP) systems use mirrors (heliostats) to focus sunlight on receivers converting thermal energy to electricity generation. Heat transfer piping systems carry molten salt or other heat transfer fluids at high temperatures (600°C or higher) through the system. Piping integrity is essential to maintain energy transport efficiency and prevent catastrophic fluid loss in populated areas surrounding solar facilities.
Thermal stress from high-temperature fluid cycling creates fatigue crack initiation and propagation risks. Advanced alloys selected for high-temperature strength must be assessed periodically confirming continued integrity. NDT consulting services develop inspection strategies accounting for extreme temperature service conditions. Ultrasonic testing detects wall thinning and crack-like defects in heat exchanger and piping systems.
Power tower systems directing concentrated sunlight onto elevated receivers employ materials and equipment operating at extreme temperatures and pressures. Heliostat tracking systems must maintain accuracy to direct sunlight onto receivers. NDTConnect platform manages inspection documentation for large CSP facilities.
Photovoltaic solar installations employ electronics and structural supports requiring minimal NDT, but thermal imaging can identify underperforming panels. Large-scale solar deployment will increasingly benefit from comprehensive asset management and condition monitoring approaches.
