The Panasonic (formerly Sanyo) HIT Double features unique characteristics, including backside power generation capability. The backside cells can increase output by an additional 30%. This power output can be maximized by installing panels over a reflective roof membrane.
Most solar panels have a power output that decreases with an increase in ambient temperature. The HIT product line has a temperature coefficient that results in greater efficiency at higher temperatures. For panel installations in ASHRAE Climate Zones 1, 2, and 3, this product line can provide significantly greater real-world output than other panel technologies.
We view this product within the same overall efficiency class as the SunPower E20 line.
