分布式光伏發(fā)電系統(tǒng)主要有太陽(yáng)能電池板、并網(wǎng)型逆變器、光伏支架、電纜線(xiàn)等基礎(chǔ)設(shè)備組成。大型一點(diǎn)的電站則還需要匯流箱、交直流配電柜及監(jiān)控系統(tǒng)等設(shè)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(yáng)能電池板：太陽(yáng)能電池板是將太陽(yáng)輻射轉(zhuǎn)換為電能的核心組件。它們通常由多個(gè)太陽(yáng)能電池組成，可以單獨(dú)使用或組合在一起以實(shí)現(xiàn)所需的發(fā)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(wǎng)型逆變器：并網(wǎng)型逆變器是將太陽(yáng)能電池板產(chǎn)生的直流電轉(zhuǎn)換為交流電的設(shè)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(yáng)能控制器：控制太陽(yáng)能電池板對(duì)蓄電池充電以及蓄電池給太陽(yáng)能逆變器負(fù)載供電的自動(dòng)控制設(shè)備。它對(duì)蓄電池的充、放電條件加以規(guī)定和控制，并按照負(fù)載的電源需求控制太陽(yáng)電池組件和蓄電池對(duì)負(fù)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(yáng)能發(fā)電系統(tǒng)的儲(chǔ)能設(shè)備，可以在太陽(yáng)能電池板無(wú)法產(chǎn)生足夠的電力時(shí)提供備用電源。常用的太陽(yáng)能發(fā)電系統(tǒng)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(xiàn)：電纜線(xiàn)用于連接太陽(yáng)能電池板、逆變器、電池和太陽(yáng)能控制器等組件，以便它們之間傳輸電能和信號(hào)。電纜線(xiàn)的選擇和安裝質(zhì)量對(duì)太陽(yáng)能發(fā)電系統(tǒng)的效率和安全性都有很大的影響。電纜線(xiàn)應(yīng)該具有足夠的導(dǎo)電性、耐高溫、耐腐蝕和耐磨損等特性，以確保系統(tǒng)的正常運(yùn)行和長(zhǎng)期穩(wěn)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(yáng)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(diào)式兩種，其中固定式支架適用于平坦地面，而可調(diào)式支架可根據(jù)地形和太陽(yáng)的位置進(jìn)行調(diào)整，使太陽(yáng)能電池板的角度和方向能夠大化地接受太陽(yáng)輻射能，提高發(fā)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.
