Solar Modules

Prism Solar’s Generation II Dual Aperture HPC solar modules generate the same energy as conventional solar panels but with 50-75% less silicon, for highly efficient, economically attractive solar collection.

Prism's DA-HPC modules are based on crystalline, bi-facial PV cells. Between the cells HPC Film strips diffract and guide direct, diffuse and reflected energy to the cells.

Dual Aperture
The HPC Film and cells collect light from the front and back surfaces, so the PV cells receive 2.4 – 3.4 times the irradiance at peak hours and over the entire day.

Passive Tracking
HPC Film collects light over a wide range of incident angles, concentrating energy on the cells to keep them near peak efficiency through the day and season. This ability enables HPC modules to operate efficiently in a range of applications including flat and sloped roof installations, vertical walls and window mountings, and large scale arrays.

More Energy in Reflection
When mounted on a white roof Prism's dual aperture modules generate up to an additional 30% more energy, without requiring additional cooling or tracking.

Better Temperature Performance
HPC Film allows wavelengths that cannot be converted by the PV cells to pass through the module rather than being absorbed as in conventional modules. The cells operate close to their ideal temperature curve without mechanical cooling—even at 3X concentration.

Improved PV Cell Efficiency
In Prism's DA-HPC modules standard PV cells are diced into narrow strings that are laid out between strips of HPC Film. The dicing and finishing operations actually improve electrical flow, adding another 3/4% to the efficiency of full-size cells.

More Efficient Cell Packing
Novel methods for overlapping and interconnecting cells results in better current handling and more reliable long-term electrical performance.

Rugged, Reliable
HPC modules are designed to face the rigors of real-world installation, with many innovative features for improved reliability. HPC modules have undergone extensive testing at the U.S. Department of Energy national lab, the National Renewable Energy Laboratory, and the Arizona State University Photovoltaic Test Lab (PTL), as well as in numerous test and installation sites around the US and Japan. HPC modules are designed to withstand the rigors of IEEE-1262 PV test standards.
