SANYO HIT (Heterojunction with Intrinsic Thin layer) bifacial solar cells are hybrids of single crystalline silicon surrounded by ultra-thin amorphous silicon layers.
Power from Both Sides
Increased power generation compared to conventional single-sided HIT panels at any angle and direction. The back side of the panel generates electricity (kWh) from ambient light that has passed through the panel or is reflected off surrounding surfaces.

Temperature Attributes
As temperatures rise, SANYO HIT Double solar panels produce more electricity than conventional crystalline silicon solar panels at the same temperature, because of their low temperature coefficient.
High Efficiency
The SANYO HIT Double solar panels maximize power within a fixed amount of space. Depending on your installation design and location’s albedo, HIT Double panels can capture additional back-side ambient light, increasing system performance. These powerful panels are ideal for grid-connected solar systems, areas with performance based incentives, and renewable energy credits.
Unique Structure
SANYO HIT Double solar panels have a double glass structure that enhances aesthetics and allows brilliant light and shadows to shine thru the panels. The panels have a silver anodized aluminum, double wall frame for extra strength. The panels come pre-equipped with touch-safe junction boxes, lead wires, MCTM plug-n-play connectors, and unique mounting rails—all of which help to minimize support BOS materials, labor, installation time and costs.
Valuable Features
SANYO HIT Double solar panels have no moving parts and weigh 50.7 pounds. The panels have a 20-Year Limited Power Output Warranty and 2-Year Limited Product Workmanship Warranty. The panels are UL 1703 safety rated for wind, hail, and fire—Class A. Unique eco-packaging minimizes cardboard waste at the job site.
Quality & Ratings
SANYO’s silicon wafers are manufactured in the USA, and the panels are assembled in Mexico at an ISO 9001 and 14001 certified factory. All panels undergo inspections to ensure strict compliance with electrical, mechanical, environmental, and visual criteria. SANYO’s conservative power ratings for models, grant more kWh per rated kW, and assist with more accurate predictions of performance and economics.
IMPORTANT: HIT Double bifacial panel’s Rated Power (Pmax) is measured at Standard Test Conditions (STC). STC does not include power produced from the backside bifacial effect of the panels. Bifacial panels may produce up to 130% of their STC rating, dependant upon installation design and location albedo—the site's reflectance rate. Use caution when selecting, calculating and sizing system components, to account for the increase in power.
To Maximize Power:
- Elevate panels above a surface as much as possible to allow reflected and ambient light beneath the panels
- Place panels over light-colored surfaces
- Do not allow support rails to cover (shade) the panel’s back face
