Slovenian solar panel manufacturer Bisol offers new solar panels with powers of 320 W and 410 W. The efficiency of the front part varies from 16.4% to 17.3% and the temperature coefficient is -0.34% per degree Celsius.
“We decided to offer smaller 320 W (BDO) and larger 410 W (BBO) versions with special matrices that offer aesthetically pleasing and cost-effective solutions for various residential and commercial projects,” a company spokesperson said. pv magazine. “The high-quality transparent backing plates provide up to 40% additional bifacial reinforcement on the back of the module, depending on the surface behind the module.”
The smaller product measures 1,722 mm x 1,134 mm x 30 mm and weighs 22 kg. It consists of 84 halved monocrystalline PERC bifacial cells, each measuring 182 mm x 91 mm. The panel’s forward current conversion efficiency is 16.4%, breakdown voltage 31.0 V and short-circuit current 13.7 A.
The dimensions of the larger module are 2,094 mm x 1,134 mm x 35 mm and the weight is 26 kg. It has 108 half-cut cells and has a forward efficiency of 17.3%. The breakdown voltage is 39.6 V and the short-circuit current is 13.3 A.
The operating temperature range of the two products is -40 C to 85 C and the operating temperature coefficient is -0.34% per degree Celsius. They have 3.2 mm high transparency, tempered glass surfaces and an IP 68 rated connection box. The maximum voltage of the system is 1500 V.
The new products have a 25-year linear power warranty and a 15-year product warranty. Their degradation is 3% in the first year, and the final power after 25 years is guaranteed to be at least 85% of the nominal output power.
