    太陽能系統性能事實與迷思
    1 白皮書 太陽能系統性能 事實與迷思 白 皮 書 除了性能，別無其他 影響太陽能系統性能的外部因素眾多，包括陽光照度、模組及環境溫度、陽光入射角、模組老化速度、 遮蔭以及製造公差。只不過，受影響的程度取決於變流器。 這是因為這類外部因素會導致串列中各模組的最大功率點（MPP）有所變化，在模組層級造成失配的 情形。使用傳統的串列變流器系統時，此種模組層級失配的情形會導致低性能模組拖累同串列內的 其他模組，進而降低太陽能發電量。 反觀SolarEdge直流優化系統，無論同串列內的其他模組性能高低，本公司的系統可讓各模組以其最 大功率點發電。此能源管理方法能消除因模組失配引發的功率損失，亦即整套系統能提升太陽能發 電量。 SolarEdge直流優化系統解決方案傳統串列變流器 各串列的MPPT－無論模組個別的MPP高低，所 有模組皆以相同的電流運作 模組層級MPPT－可在模組層級調整電流及電壓…
