Description
The HT-SAAE HT66-166M-405 is a compact, installer-friendly module built to deliver strong energy density on tight rooftops and small C&I arrays. It uses half-cut monocrystalline PERC cells with a multi-busbar layout to reduce resistive losses and improve shade behavior, while the transparent rear captures reflected light to boost real-world kWh—especially over bright roof membranes, concrete, gravel, or snow.
A black anodized frame and dark front provide clean curb appeal without sacrificing performance. With a modern 1500 VDC system rating, IP68 junction box, and MC4-type leads, the module drops into today’s string designs and common racking.
Robust mechanical load ratings, positive power tolerance, and tight factory binning help keep BOS simple, minimize mismatch across longer strings, and support low LCOE over decades.
Product Details
-
High energy density in small spaces: 132 half-cut mono PERC cells (M10/≈182 mm) with multi-busbar wiring improve thermal behavior and reduce series resistance.
-
Installer-friendly hardware: 1500 VDC strings, MC4-type connectors, and standard module width simplify clamp selection and BOS integration.
-
Durable construction: 3.2 mm AR/self-clean glass, IP68 junction box with three bypass diodes, and proven snow/wind ratings for harsh climates.
-
Consistent arrays: Positive power tolerance (0 to +5 W) and tight binning help limit mismatch and speed commissioning.
-
Clean aesthetic: All-black front with black frame keeps arrays looking uniform on visible rooftops and carports.
