The conversion rate is 24.6%! Enel of Italy launches 680W n-type heterojunction photovoltaic cell
According to reports, Enel Green Power (EGP), a subsidiary of Italian utility company Enel, recently launched its latest photovoltaic modules at the 8th World Photovoltaic Energy Conversion Conference held in Milan, Italy.
The latest product from Enel is a heterojunction bifacial PV module for utility-scale PV projects. The product is based on an n-type photovoltaic cell in G12 format with a power conversion efficiency of up to 24.6%.
The current photovoltaic cell is 150µm thick, but the company's technology roadmap has set a target of 120µm by the end of 2025.
There are 9 versions of this product with power outputs ranging from 640W to 680W and average efficiencies ranging from 22.6% to 22.9%. The open circuit voltage is 43.3V to 44.2V and the short circuit current range is 18.9A to 19.8A.
The solar panels of all versions measure 2,172mm x 1,303mm x 35mm and weigh 36kg. The maximum system voltage is 1,500V, and the bifaciality reaches 95%. It can be used in the working temperature range of -40℃～85℃, and the working temperature coefficient is -0.24%/℃. The photovoltaic cells are enclosed between 2mm photovoltaic glass with anti-reflection treatment, and also feature an IP68-rated junction box and an anodized aluminum frame.
The new products will come with a 30-year linear power output guarantee and a 20-year product quality guarantee. The degradation rate is said to be 1.0% in the first year, and the power output after 30 years is not less than 93% of the nominal output power.
