Check length, width and support together
The listed 1662 × 790 mm envelope needs its own roof-layout review. Record the available support, obstructions and service access rather than selecting solely by the higher wattage. The module’s thin profile does not define how it may be curved or supported.
Review the higher-voltage module option
The listed maximum-power voltage is 43.81 V. Ask for the complete electrical data and compare it with the chosen charge controller and battery architecture. A controller’s acceptable input window cannot be confirmed from the module’s maximum-power voltage alone.
Evaluate the intended roof configuration
Shading pattern, cable routing and the manufacturer’s mounting requirements belong in the same sample brief. Confirm the exact connector and drawing before agreeing on the evaluation hardware. Record the actual mounting and charging configuration so a successful observation is not extended to a different roof arrangement without review.
