Zepren - INCUS Portable Solar Spectrophotometer

The INCUS Portable Solar Spectrophotometer, created through the collaboration of ZEPREN Solutions and Aragon Photonics, is designed for precise measurement of optical properties in parabolic trough CSP plants. It enables assessment of outer tube transmittance and inner tube absorbance within solar fields, per ISO9050 and ASTM-G173 standards. The robust design features an ergonomic handle, allowing versatile positioning, and safeguards against damage through advanced mechanical and electronic configuration. With capability for 400+ measurements per battery charge and GPS data logging, it supports Operation and Maintenance activities like soiling ratio control, aiding in optimal cleaning scheduling. Measuring across 14 wavelengths (365-1950 nm), it maintains high accuracy with minimal ambient interference. The spectrophotometer includes features like tagged measurements storage, self-calibration via an accessory pattern mirror, and proprietary software for data visualization and preservation. It supports tubes of different sizes, ensuring adaptability to various solar field conditions.

Zepren - ATMOS Atmospheric Attenuation Monitoring

The ATMOS Atmospheric Attenuation Monitoring System, developed by Aragon Photonics and exclusively licensed to ZEPREN Solutions, is specifically designed for Concentrated Solar Power (CSP) tower plants. It autonomously measures atmospheric transmittance in real time, utilizing optical spectrum analysis. This technique helps distinguish the origin of attenuation by analyzing the spectrum of sunlight reflected by a target screen, which is further assessed by two telescopic optical devices. These devices measure the spectrum and compute the differential path attenuation across a wavelength range of 400-1630 nm. A key application of ATMOS is to monitor efficiency losses linked to atmospheric attenuation, facilitating site assessment for CSP plants. The system adheres to the ISO 9050 standard, ensures self-calibration, and includes a unique algorithm for classifying invalid measurements during abrupt atmospheric changes. Its hardware features automatic alignment to maintain consistency in measurements without external calibration.
