Siemens SR100 / SR90: product photograph restored from the original low-resolution picture.
The SR100 and SR90 are the largest SR modules: 100 W and 90 W from 36 cells on a 1498 × 594 mm frame, 10.9 kg, in 12 V and 6 V versions. Like the SR50 they list the 10-year, 90 % and 25-year, 80 % warranty tiers.

With 36 cells in series the Vmp is 17.7 V at 25 °C. With 60 °C cells it falls to about 14.8 to 15.5 V (the datasheet gives no Vmp coefficient: the lower figure assumes a typical −0.47 %/K, the upper scales the Voc coefficient), a margin of +0.4 to +1.1 V against 14.4 V. The margin stays positive under both assumptions. In 5 peak-sun-hours the 12 V version adds roughly 21.0 Ah a day to a 12 V battery (Imp × 5 h × 0.75).

Notes from the datasheet. (1) Electrical values at standard test conditions: irradiance 1000 W/m², cell temperature 25 °C, spectrum per ASTM E892 (air mass 1.5). (2) Nominal operating conditions: 800 W/m², ambient 20 °C, wind 1 m/s. (3) Qualification tests per CEC 503. (4) Diagonal lifting of a module corner with three corners fixed. (5) Warranty applies to the original consumer purchaser; see the full limited warranty for conditions. The tier percentages refer to the minimum power rating (Pmin), not the rated power.
