SHELL Solar Modules

ST Series

CIS Thin-Film Solar Module for battery charging and small applications
The ST modules are composed of monolithic structure of series-connected Copper Indium Diselenide (CIS) based solar cells. These multiple-layer cells, a product of Shell Solar is a proprietary material, structure and process technologies, called PowerMax® thin film technology, are characterized by exceptional spectral response and long-term performance integrity. They give the ST Series solar modules performance efficiency similar to crystalline photovoltaic modules.

Engineered for durability and ease of use, the ST modules are manufactured under strict quality controls in ISO 9001 certified facilities. A black-anodized aluminum frame secures the glass-front laminate which encapsulates, protects and electrically isolates the solar cells. This rugged construction enables the ST modules to endure even severe environmental events and continue to generate power reliably and efficiently.

Designed for use in 12 volt and 24 volt (with 2 modules in series) systems, the ST modules perform efficiently in all operational conditions. Their distinctive ability to deliver battery-charge power levels in low-light situations make them particularly effective for specialized telemetry and SCADA applications and in adverse or changeable environments. Five year limited warranty on power output. All ST modules have the CE mark of certification.
