太陽能發電系統可概略分為市電併聯型與獨立型兩種。本文主要是討論獨立型太陽能系統應用時所面臨的問題。太陽能電池易受模組匹配、遮陰等因素造成系統發電不如預期；而儲能系統多以電池代表，適當的電池管理系統可增加電池使用壽命，進而增進太陽能系統應用之可靠度。本研究採用新穎的分散式太陽能發電架構，各片太陽能板將各接一組直流電壓轉換器，使各片獨立運作不受其他模組影響；儲能元件以成本考量下使用的是鉛酸電池。考慮鉛酸電池組各顆電池本身充放電特性差異時造成電量儲存不均，長期下來電池損壞的機率會升高，故整合電池均衡充電技術以均勻每個電池電量，從而提高了電池的壽命。
　　實驗驗證分為二階段，先以定電流的方式測試均衡充電系統，再將分散式太陽能發電與均衡充電技術整合測試。依實驗結果，吾人提出一簡單的充電與均充邏輯，整合於獨立式太陽能發電系統。相關成果，未來除了可供偏遠地區獨立型太陽能電力使用，也可協助太陽能輔助電力載具之發展。

The photovoltaic energy system is divided into grid-connection type and stand-alone type. This study is to discuss the application problems of stand-alone type photovoltaic system. The factors of module matching and shading in the photovoltaic energy system cause power weakly. However, the saving system is represented by battery in which the management system will expand the life of battery. It is setting up a DC converter on each solar panel in output terminal. Moreover, each solar panel operates independently. The energy-storage element used lead-acid batteries in cost considerations. However, the consideration about the characteristics of the lead-acid battery is differences in electricity power uneven. The possibility of damage will rise in long periods. Therefore, we decided that integrating charge equalization system into Stand-alone type distribute photovoltaic system. It enhances the uniformity of the battery cells and hence improves the life of the battery.
Experimental verification is divided into two stages, the first way to test the charge equalization system in constant current mode, and then distributed photovoltaic system and equalization charging technology integration testing. According to experimental results, we propose a simple charge and equalize logic integrated in the stand-alone photovoltaic energy system. Therefore, the results not only can use in the remote area where has stand-alone photovoltaic energy system for the future, but also can assist to the development of the autonomous solar ship.
