在21世紀，太陽能是最受歡迎的再生能源。太陽能相關開發在實驗室已有多年。本文嘗試將太陽能系統運用在2kW太陽能動力船上。
本文設計了一個完整的太陽能動力船系統。此系統主要有太陽能系統、電池管理系統及監控系統。太陽能系統最大功率追縱(MPPT)技術是運用實驗室開發的二次式極值法(QM method)。因船在水上會有搖擺的現象，因此會影響到最大功率追縱結果。為了能更快速的進行MPPT演算所以選用了二次式極值法。所有的太陽能板都會銜接到一片DC/DC 轉換器，以將太陽能電力轉換到電池組中。因船型的關係吾人選用了不一樣型號的多晶矽太陽能板。為此吾人可測試DC/DC轉換器的穩定性。電池管理系統(BMS)用於管理電池組的電量。其最主要功能為切換電池組的充/放電。在此系統中擁有三個模式，分別為手動模式、定時模式及電池組電壓比較模式。監控系統是用以監控全船資訊並且控制其他系統的操作。吾人將所有系統安裝到一艘八米木船上，並且完成實測與評估。

In 21st century, the solar energy is the favorite renewable energy. The photovoltaic of our laboratory already research for few years. Now we try to apply our photovoltaic system in a 2kW solar powered boat.
In this thesis, we design a fully complete solar powered boat monitoring system. The main system in solar powered boat is photovoltaic (PV) system and battery management system (BMS). In the photovoltaic system we use the quadratic maximization (QM) method to do the maximum power point tracking (MPPT). The ship on the water always swing, it will affect the MPPT tracking. So a faster MPPT method is necessary so we choosing the QM method. Every PV panel will connect to a DC/DC converter which can convert the solar power to the battery bank. Depends on the ship shape we use different model polysilicon PV panels. We also test the stability of the DC/DC converter. The battery management system (BMS) is use for manage the battery bank capacity. The main feature of BMS system is switching the battery bank to charge /discharge. In the BMS system has three different switching modes which is manual mode, time setting mode and battery bank voltage compare mode. We install our system to an 8 meter wooden ship and evaluation the system.
