Low voltage thanks to parallel connection

The HIT-H250E01 is said to have nominal power of 250 watts peak and module efficiency of 18 percent, while the HIT-H245E01 is quoted at a nominal power of 245 watts peak and module efficiency of 17.7 percent. The cells of HIT modules form a hexagonal honeycomb design that’s said to reduce waste in production and optimally exploit module surface area.

The cells are furthermore connected partly in parallel, so a lower voltage is reached than in previous models, permitting the configuration of a single string of 20 modules with an output of five kWp. Front glass with an anti-reflective coating is said to increase the light absorption of the modules, yielding higher efficiency.
