The Future is Here!

OVERVIEW

Photovoltaic (PV) cells are made from semiconductors of which two types, crystalline silicon and thin film, are currently the most popular. Crystalline silicon is the most common type in use due to their history of development and the large number of companies manufacturing various types of silicon based panels. They dominated the world solar panel market.

Realizing that there are new technologies available and that silicon panel development is close to reaching its maximum efficiency level, plus the fact that silicon based panels have several long-term and short-term performance shortcomings has led to great interest in non silicon technologies.

 In the thin film non-silicon area the main types of PV cells presently in the market are CIS (copper, indium, selenium) and CIGS (copper, indium, gallium, selenium). The third and currently the type that has the largest share of the thin film market is CdTe. This type of panel contains the compounds of Cadmium and Tellurium. Cadmium is classified as a dangerous carcinogen and the panels require recycling after use to protect against possible serious health damage related to exposure to cadmium. CdTe type panels are also less efficient than either CIS or CIGS type panels.

 At the present time, thin film panel manufacturers concentrate in supplying their products for large commercial projects. Our manufacturer is one of the first companies to make their CIGS panels available to the entire solar market.

 In the thin film group, CIGS technology has demonstrated the highest efficiency rating, high stability in (kwh) output, little or no degradation and excellent performance in low light conditions.

 We answer the question “Why CIGS?” and we outline details about our products.

 CIGS Product Applications:

1)      Standard modules- all rooftop PV type installations and power plant applications.

2)     Roof Tiles- excellent for slant roof residential home PV applications.

3)     “See-through” (BIPV) module- can be put to use as a building component providing functional use beyond energy generation. (eg: roof skylights, windows, facades, shade areas and canopies.)

4)     The (BIPV) can also be used for agricultural greenhouse structures.
