Advanced Solar Photonics launches bifacial glass-to-glass photovoltaic modules

By Greentech Lead America: Advanced Solar Photonics,
(ASP), a manufacturer of photovoltaic equipment and provider of turnkey
alternative energy systems, has introduced mono-crystalline bifacial
glass-to-glass PV module series made in America. The bifacial G2G module
will increase overall module efficiency by 10 percent.

The bifacial dual sided glass module (G2G) generates more electricity by
converting direct, radiant and scattered solar energy on both the front and the
back side of the module. To increase the efficiency, ASP uses a special
holographic material sandwiched between the silicon and EVA layers, maximizing
the time per day the modules can generate electricity from the sun.

ASP bifacial G2G modules’ low temperature coefficient
helps produce more electricity than conventional crystalline silicon solar
modules at the same temperature. Together these features can result in energy
output as much as 30 percent higher than conventional technology. 

“The bifacial G2G technology marks a major turning point in photovoltaic
system technology. We’ve replaced costly single-axis and double-axis mechanical
tracking systems with much cheaper optical tracking panels and achieved the
same efficiency increases,” said Thomas Gregory, chief strategy officer at
ASP. 

Assuming an average system cost of $4/Watt for a conventional fixed ground-mount
system, ASP’s bifacial G2G panels will increase energy generation by about
30 percent by adding approximately $0.50/Watt to the overall cost of the
system.


The glass-to-glass lamination method, with no multi-layer back sheet, results
in reduced fire hazard and less probability of mechanical damage over the
lifetime of the module. Thinner glass ensures less heat, thermal stability,
resistance to impact and elimination of micro fractures. A frameless
construction requires less connections, materials and labor resulting in
compact packaging and facilitated transportation.

The bifacial G2G modules have a usable lifetime of 50
years without danger of mechanical damage or temperature/ humidity-related
delamination of the back sheet, resulting in a loss of energy production
performance or outright failure. 

This breakthrough PV product is made up of 60 bifacial mono-crystalline silicon
cells with up to 20.5 percent module efficiency on both sides. The total rated
power output of the panel will range from 271 Watts to 333 Watts.
