Outstanding Power Performance
The SR50 solar photovoltaic modules efficiently generate power by converting the energy contained in sunlight directly into electricity. They have no moving parts, operate silently, use no fuel, and produce no waste. Built for long-term dependability, the SR50 has a twenty-five year limited warranty on power output.

The SR50 datasheet is also available in the Adobe Acrobat (.PDF) format.

If the designer chooses to use the 6-volt version in a high voltage array configuration, the designer must install custom large bypass diodes and heat sinks around every 6-volt parallel string.

1

Determined under standard test conditions (STC): Irradiance = 1000w/m² cell temperature = 25 °C; solar spectral irradiance per ASTM E892 (Air Mass = 1.5).

2

Determined under nominal operating conditions (NOC): Irradiance = 800 w/m² ambient temperature = 20 °C; wind speed = 1m/s.

3

Qualification Tests performed as per CEC 503 Test Specification, to ensure durability and performance in outdoor conditions.
