For many years the HIT solar modules made by Sanyo have been well known not only for their very high conversion efficiency but also for their excellent product quality. By applying the highest standards to the selection of materials as well as to the complete cell- and module production process, extremely low failure rates could be achieved.
As of the end of March 2011 more than two million solar modules have been produced in the Sanyo factory in Hungary for the European market and out of these, less than 50 modules have been returned by customers on guarantee claims. This excellent product quality has made Sanyo confident to extend its product guarantee to 10 years for all of its HIT solar modules.
This 10-year guarantee is applicable to solar modules of the standard series NxxxSE10/SE11 from May 1, 2011 modules of the HD-series HxxxE01/02; for the HIT-Double modules DNKHE1 and DNKHE1-2 and for the modules of the HDE4 / HDE4-2 and NKHE5 / NKHE5-2 series.
New standards have been set by Sanyo in conversion efficiency with its N-series, with a cell conversion efficiency of 21.6 percent and module conversion efficiency of 19 percent.
Belief that high product quality and a long product life-time are essential product features vital for the economic success of any PV system.
The increased guarantee period of 10 years underlines a big commitment.
Sanyo is convinced that such long guarantee periods will become industry-standard and may even become mandatory in some countries.
