How much energy yield does Huawei optimizer's module-level optimization technology increase by reducing the mismatch...

The exact extract asks how much Huawei optimizer module-level optimization technology increases energy yield by reducing mismatch impact. The correct answer is C. 5~30%. The technical reason is that PV modules in the same string normally operate under a shared current constraint. If one module is shaded, soiled, aging differently, or affected by a different orientation, the output current of that weaker module can drag down the whole string. Huawei’s Smart Module Controller/optimizer reduces this mismatch impact by enabling module-level maximum power point tracking behavior, allowing each module to operate more independently and reducing the loss caused by the weakest module. Huawei’s Smart Module Controller safety white paper specifically states that higher yields can increase energy yield by 5–30% by reducing mismatch. Huawei’s product page also positions the Smart Module Controller as providing module-level optimization, rapid shutdown, flexible layout, and higher yield. Therefore, option C is the exact value range required by the extract. References: Huawei Smart Module Controller Safety White Paper; Huawei Smart Module Controller product page.
