⚠️ Important Testing Disclaimer
Please note:
-
All product specifications listed (voltage, current, power) are based on SunPower®’s internal Me3 bin test data under STC conditions.
-
However, our cutting process, measurement tools, and test protocols follow our own internal standards, not SunPower’s original lab calibration.
-
Due to the nature of manual cutting and edge loss, actual performance may vary slightly from theoretical values.
⚠️ We do not guarantee that your DIY project or custom test results will match our provided data. Variations may occur due to soldering methods, ambient conditions, contact quality, or module design.
We will do our best to share technical advice and data sheets upon request, but:
-
We cannot be held responsible for final output, performance deviation, or unexpected behaviors during integration.
-
This product is intended for research, prototyping, and educational use.
For professional module integration, we strongly recommend independent testing under your own system conditions
