Remarks:
1. The modules electrical ratings are measured under Standard Test Conditions (STC) and have been delivered on the specific table of electrical characteristics as shown above.
2. A photovoltaic module may produce more current and/or voltage than reported at STC. Sunny, cool weather and reflection from snow or water can increase current and power output. Therefore, the values of Isc and Voc marked on the modules should be multiplied by a factor of 1.25 when determining component voltage ratings, conductor ampacities, fuse sizes, and size of controls connected to PV output.
3. [STC]: 1000 W/m2 , AM 1.5, 25 degree C.
4. The exactly measured electrical characteristics are shown on the label of the modules .
5. All electrical data is average production data and is subject to a measuring equipment tolerance of Module nominal power is subject to a tolerance of +/- 2%.
