International Certification
The Heliostat has passed the quality inspection of CSP Services, a prestigious third-party institution, and obtained the certification report jointly issued by CSP Services and DLR. According to the report shows that the heliostat is characterized by minor reflector slope deviation and high tracking accuracy. In particular, the tracking performance of the heliostats is considered excellent, which is the best remark by CSP Services when carrying out the third-party test evaluation.

Influence on theavailability of solar field
During the construction period of the plant
By adopting the correction system of Cosin Solar, the calibration time of the solar field can be greatly reduced, thus shortens the delivery time. At the same time, the installation cost can be greatly reduced because the heliostats installation process does not require accurate positioning and measurement of deviation.
After the plant is put into operation
The calibration system of Cosin Solar can carry out high frequency periodic calibration on the operating mirror field, ensuring that during the whole life cycle, the full-field heliostat is always at the best accuracy level.
