Solar Panels

Sanyo has been researching photovoltaic
technology since 1976, and Solec solar electric modules have been in
both urban and remote use since 1967. They joined forces in 1994. Solec
has pioneered major improvements in crystalline silicon PV technology
for high-power PV applications, and both Solec and Sanyo hold numerous
patents and proprietary advances. ISO 9001 & ISO 14001. UL 1703,
cUL, and CEC listed. 20-year power output warranty.
In 1997, Sanyo introduced a product called HIT Power 21™,
a hybrid that combines single crystalline cell technology with amorphous
silicon cell technology for a 20% lab efficiency rating. The cell is
composed of thin monocrystalline silicon wafer surrounded by ultra-thin
amorphous silicon layers. HIT solar cells improve boundary characteristics
and reduce power generation losses by forming impurity-free i-type amorphous
silicon layers between the crystalline base and p- and n-type amorphous
silicon layers. Minimizing power generation losses in the non-regular
grid area on the solar cell surface guarantees a higher output.

Industrial Technology Development Organization (NEDO) in Japan.
