HULKet emphasized the importance of power output, noting its Cigs-3000 Series achieves 30% more accumulated power, producing considerably more KWh/KWp, than crystalline silicon (c-Si) modules. This power gain is delivered through the combination of superior spectral responses in terms of both UV and IR light, a lower temperature coefficient, less shading influence, enhanced lower incident, scattered & diffuse light performance, and the positive light soaking effect.
“The ‘power gain factor’ is a vital measurement for all PV modules,” commented Brian Sung, founder and President, HULKet. “Regardless of the operating environment, including hotter climates, our Cigs-3000 Series delivers a sizeable power boost when compared to crystalline silicon modules. The consistent power output combined with the green design provides a superior product and investment.”
The commercial-sized (2.348 m2) Cigs-3000 Series CIGS thin-film PV module is a new green design which replaces cadmium-sulfide (CdS) with a zinc-sulfide (ZnSx) buffer layer. The module, three side-by-side cells measuring 1.901m x 1.235m and weighing 33.3 kg, was inspected and certified in accordance with RoHS by TUV Rheinland AG.
In addition, the temperature coefficient of Pmpp is (- 0.23 % /o C) – the lowest record of global commercial solar modules. The average conversion efficiency is 14% in mass production.
According to HULKet, the average BOS (balance of system) cost for a Cigs-3000 Series module is up to 60% lower than that for three conventional CIGS thin-film PV modules, such as the HULKet CDF-1000 Series. The reduction in BOS costs is due to using a smaller volume of installed components and materials, such as mounting frames, DC connectors and cable, as well as less labor requirements. As a result, the new Cigs-3000 Series is competitive with c-Si solar cells in total installation costs.
HULKet is currently seeking U.S. distributors and large-end users in this market.
