About CIS
CIS stands for the elements Copper (C), Indium (I) and Selenium (S) that are used in thin film solar modules. CIS modules have numerous advantages over conventional crystalline silicon modules.
CIS is 100 times thinner and non-toxic.
CIS modules are better for the environment. At 2—3 micrometers thick versus 200—300 micrometers of typical crystalline modules, CIS uses less natural resources. As a cadmium-free, non-toxic product, CIS fully complies with European RoHS (Restriction of Hazardous Substances)
CIS is the Energy Payback Time (EPT) leader.
EPT is the amount of time required in operation to recover the energy spent in producing the modules themselves. Simply put, CIS modules require less energy to produce—60% less than the current industry standard crystalline
silicon.
CIS alone benefits from "light soaking.'
Independent tests consistently confirm up to 10% increased output over the factory rating once CIS modules are installed. This is due to unique chemical properties in our CIS modules that are superior to other technologies.
Continuous operation with shadows.
The circuitry of a CIS module allows it to continue producing electricity even when part of of the module is covered by shadow. Crystalline silicon modules entirely stop generating power under the same conditions.
Esthetics
Most agree that the more uniformly dark color of CIS modules looks best.

Advantages of CIS modules
- beautiful deep colored appearance that fits most types of house roofs
- better Energy Payback Time compared to silicon type modules
- free from world's solar grade silicon supply shortages that affects the stable supply of silicon solar modules
- free from toxic materials including cadmium, lead
