Brief on Solar Panels Technologies
We deal in most popular and widely used crystalline solar panels. However brief on all technologies are given for your reference and study.
Crystalline silicon is still the mainstay of most PV panels. Although in some technical parameters it is not the ideal material for solar cells, it has the benefit of being widely available, well understood and uses the same technology developed for the electronics industry. Efficiencies of more than 20% have been obtained with silicon cells already in mass production
Mono Crystalline Solar Cell / Module
The material with a single crystalline formation and crystalline framework is homogenous, which can be recognized by an even external coloring. In single crystal silicon, the crystal lattice of the entire sample is continuous and unbroken
Poly (Multi) Crystalline Solar Cell / Module
Semiconductor (photovoltaic) material composed of variously oriented, small, individual silicon crystals. Polycrystalline cells can be recognized by a visible grain, a “metal flake effect”.
Thin Film Solar Module
Thin film modules are constructed by depositing extremely thin layers of photosensitive materials on to a low cost backing such as glass, stainless steel or plastic. These results in lower production costs compared to the more material intensive crystalline technology, a price advantage which is counterbalanced at the moment by substantially lower efficiency rates.
Three types of thin film modules are commercially available at the moment. These are manufactured from:
- Amorphous Silicon (a-Si),
- Copper Indium Diselenide (CIS, CIGS),
- Cadmium Telluride
