分布式光伏發電系統主要有太陽能電池板、并網型逆變器、光伏支架、電纜線等基礎設備組成。大型一點的電站則還需要匯流箱、交直流配電柜及監控系統等設備。

The distributed photovoltaic power generation system mainly consists of basic equipment such as solar panels, grid connected inverters, photovoltaic brackets, and cable lines. Larger power stations also require equipment such as combiner boxes, AC/DC distribution cabinets, and monitoring systems.

太陽能電池板：太陽能電池板是將太陽輻射轉換為電能的核心組件。它們通常由多個太陽能電池組成，可以單獨使用或組合在一起以實現所需的發電量和效率。

Solar panels: Solar panels are the core components that convert solar radiation into electrical energy. They are usually composed of multiple solar cells, which can be used alone or combined to achieve the required power generation and efficiency.

并網型逆變器：并網型逆變器是將太陽能電池板產生的直流電轉換為交流電的設備，其輸出的交流電可以和市電的頻率及相位同步，因此輸出的交流電可以回到市電。

Grid connected inverter: Grid connected inverter is a device that converts direct current generated by solar panels into alternating current. Its output alternating current can synchronize with the frequency and phase of the mains power, so the output alternating current can return to the mains power.

太陽能控制器：控制太陽能電池板對蓄電池充電以及蓄電池給太陽能逆變器負載供電的自動控制設備。它對蓄電池的充、放電條件加以規定和控制，并按照負載的電源需求控制太陽電池組件和蓄電池對負載的電能輸出。

Solar controller: an automatic control device that controls the charging of solar panels to batteries and the power supply of batteries to the load of solar inverters. It regulates and controls the charging and discharging conditions of the battery, and controls the electrical energy output of the solar cell components and the battery to the load according to the power supply requirements of the load.

電池組：電池是太陽能發電系統的儲能設備，可以在太陽能電池板無法產生足夠的電力時提供備用電源。常用的太陽能發電系統電池包括鉛酸電池和鋰離子電池。

Battery pack: The battery is the energy storage device of a solar power generation system, which can provide backup power when the solar panels cannot generate enough electricity. The commonly used solar power system batteries include lead-acid batteries and lithium-ion batteries.

電纜線：電纜線用于連接太陽能電池板、逆變器、電池和太陽能控制器等組件，以便它們之間傳輸電能和信號。電纜線的選擇和安裝質量對太陽能發電系統的效率和安全性都有很大的影響。電纜線應該具有足夠的導電性、耐高溫、耐腐蝕和耐磨損等特性，以確保系統的正常運行和長期穩定性。

Cable: Cable is used to connect components such as solar panels, inverters, batteries, and solar controllers for the transmission of electrical energy and signals between them. The selection and installation quality of cable lines have a significant impact on the efficiency and safety of solar power generation systems. The cable should have sufficient conductivity, high temperature resistance, corrosion resistance, and wear resistance to ensure the normal operation and long-term stability of the system.

光伏支架：用于支撐固定太陽能電池板，通常分為屋頂支架和地面支架。屋頂支架分為平面支架和斜面支架兩種，其中平面支架適用于平頂或輕型屋頂，而斜面支架適用于傾斜屋頂；地面支架分為固定式和可調式兩種，其中固定式支架適用于平坦地面，而可調式支架可根據地形和太陽的位置進行調整，使太陽能電池板的角度和方向能夠大化地接受太陽輻射能，提高發電效率。

Photovoltaic bracket: used to support and fix solar panels, usually divided into roof bracket and ground bracket. Roof supports are divided into two types: flat supports and sloping supports. Flat supports are suitable for flat or light roofs, while sloping supports are suitable for sloping roofs; Ground supports are divided into two types: fixed and adjustable. The fixed support is suitable for flat ground, while the adjustable support can be adjusted according to the terrain and the position of the sun, allowing the angle and direction of the solar panel to receive solar radiation to the greatest extent possible and improving power generation efficiency.
