Sanyo HIT Double PV Solar Modules: Provides 30% More Power with Less Solar Panels

Glad to see notice of Sanyo’s bi-facial cell technology. We at Prism Solar are big fans of Sanyo’s high efficiency HIT cells, including the bi-facial version, but it is more accurate to note that the HIT Double has been available for some time. Only the installation on Durock’s roof was new. While we appreciate you mentioning Prism, the similarity to HIT Double is that both modules can make electricity using light on both sides of the module – that’s why a reflective roof of whatever kind is helpful. We hope someday that Sanyo will also use Prism’s holographic film with their excellent HIT cells – this would allow half or fewer cells per module to be used (or if you prefer, make two modules from same # of cells) to make lower-cost high net power (kWh/Wp) modules. Our film works with all kinds of PV cells, but Sanyo’s bi-facial cells are especially good for taking advantage of the film’s light enhancement power.
