Stability & Certification

Full-Size Stability Testing (TÜV & IEC Standards) Our Alphaglass PV panels are tested using full-size panels, ensuring accurate real-world performance. Unlike some testing methods that rely on small samples (e.g., 5×5 cm), our approach reflects actual installation conditions. All tests comply with relevant IEC 63163 standards and are verified by TÜV SÜD.

Product FAQs

What makes CPTI‘s PV different from other solar modules?

CPTI's PV is designed to harvest energy from a wide range of light sources, including standard sunlight, ambient light, and indoor light. This makes it suitable for any energy harvesting applications.

How do I connect Alphaglass to my device?

The module provides simple wire outputs:

Red wire: Positive (+)
Black wire: Negative (–)

You can connect it directly to a battery charging circuit or power management module.

A blocking diode is recommended to prevent reverse current when light levels are low.

Is CPTI's PV RoHS and REACH compliant?

Yes. all CPTI's PV modules are RoHS and REACH compliant, ensuring that the materials used meet international environmental and safety standards.

Do I need a battery with Alphaglass module?

For most applications, yes.

Because light conditions can vary, it is recommended to connect Alphaglass to a rechargeable battery or supercapacitor so the harvested energy can be stored and used when needed.
