Power after 30 years
  • Efficiency of 22.4% matches the HJT 650-700W median
  • Power density of 223.7 W/m² matches the HJT 650-700W median
  • At -0.24%/°C, hot weather performance is typical for HJT 650-700W panels
  • 37.3 kg weight - 1.2 kg lighter than HJT 650-700W median (38.5 kg), reducing installation effort
  • Bifacial design (85% factor) captures reflected light - adds 4-13% yield on ground-mount or white roof

Show series description

The Haitai Solar JT SLk(B) 690-720W series is designed for large-scale installations where maximizing energy output from a given area and stable performance in varying conditions are crucial. The use of N-type HJT technology results in very high efficiency and excellent resistance to typical operational issues, such as accelerated power degradation over time. The modules have a bifacial design, allowing them to also utilize reflected light from the ground – a significant advantage on bright roofs, gravel, and ground-mounted farms.

In practice, the JT SLk(B) series addresses a common dilemma for investors: how to minimize BOS (Balance of System) and installation costs without compromising energy production. The high power output of a single module and the 1500 V system facilitate the design of longer strings and reduce the number of components in the installation. Another advantage is the IP68 rating for the junction box, which enhances reliability in harsh conditions. This makes it a good choice for PV farms, C&I (Commercial & Industrial) installations, and projects focused on a quick return on investment.
