Energy yields

Heat-tolerance and long-term stability

Soltecture’s modules achieve high yields. At hot locations, users benefit from the excellent temperature coefficients of the Soltecture modules, which perform better under hot conditions than modules made from crystalline silicon. In addition, Soltecture grades its modules in terms of increasing yields and thus ensures that every package contains more capacity than is listed on the label. The modules thus supply an above-average number of kilowatt-hours per installed watt peak (kWh/kWp). And that is not only in the first year: in contrast to thin-film modules made from amorphous silicon, the yields do not drop in the second operating year but continue to work at a consistently high level.

Annual energy yields

Results of monitoring solar power systems

The graphics compare the energy yields of Soltecture modules with those of other module types. These display the test results for flat roof systems situated in a relatively cool region (Berlin) and in a hot region (Greece). The CIS modules have remained just as stable throughout the entire monitoring period as the comparison modules made from polycrystalline silicon. The thin-film solar modules from amorphous silicon, on the other hand, have lost more than 10% of their performance capability after the first operating year. In Greece it was noted that the annual energy yields in kWh/kWp for the CIS modules were around 5% greater than the comparison modules from crystalline silicon.
