A new, more efficient solar panel from Sanyo has been made available for the United States market. SANYO North America Corporation has announced the availability of its HIT Power 225A solar module, a product that claims to be the most efficient HIT Power solar module launched to date in the US.

A version of this panel is now in use on a parking structure at Long Beach City College. According to the SANYO press announcement, the 225A panel offers integrators and installers independently certified cell conversion efficiencies of 20.2 percent and module efficiencies of 17.8 percent.

Power generation output for the new panel is higher than traditional panels because of solar cell technology that combines high-efficiency monocrystalline silicon with ultra-thin layers of amorphous silicon.

“SANYO’s HIT Power module performance gives integrators and installers 100 percent of the nameplate rated power – or more,” said Charles Hanasaki, President of the SANYO North America’s Solar & Smart Energy division, “With a co-efficient of -0/+10 percent, HIT Power’s warranted tolerance is the most generous the industry has to offer.”


HIT stands for Heterojunction with Intrinsic Thin-layer. The acronym may be the most difficult part of the learning process, but the benefits in efficiency are apparent. HIT solar cells are composed of single crystalline silicon wafers that are surrounded by ultra-thin amorphous silicon layers.

This simple structure minimizes defects within the p/n junction of the cell, producing highly efficient cells capable of achieving up to 17.4 percent module efficiency while producing more power even at higher temperatures. Those wishing to witness the panels in action can visit Long Beach City College.

The school has opened a new campus parking structure where it is installed over 400-kilowatts of SANYO’s HIT Power solar panels. The new system was installed to fully-power security lights, elevators, four emergency phones on each level as well as fire protection systems. Adjacent buildings on campus will use any excess power that is generated.

“With the installed solar system, we have been able to turn an ordinary parking garage into an extraordinary solar power plant, accomplishing both a reduction of our carbon footprint and our electricity bill at one time,” said Tim Wootton, Director of Facilities at Long Beach City College.
