panels have an average 10% efficiency and are used in applications
with low energy demand. For higher energy requirements mono-crystalline
panels are mostly used because of their higher efficiency (almost
14%) resulting in the decrease of the required installation area.
The panels utilize industry standard construction techniques to ensure
long life even in the most severe environments. Every module is covered
by a comprehensive 10-year warranty, and meets all applicable industry
and consumer standards for safety and reliability. PV modules are
made of high efficiency silicon PV cells, capable of producing energy
with only 4-5% of solar radiation. All models from 38 Watts have junction
boxes wired - in by-pass diode to reduce possible loss of power from
partial arrays shading. The summary of the electrical and physical
characteristics of our modules is shown below: |

Amorphous
Si (a-Si) Panels
Material consumption is lower during the manufacture of these solar
cells and the production processes are cheaper resulting in lower
cost than the other PV panels. One disadvantage is that their efficiency
is set lower than 10%. One interesting application is their incorporation
in the building's architecture.
