分布式光伏发电系统主要有太阳能电池板、并网型逆变器、光伏支架、电缆线等基础设备组成。大型一点的电站则还需要汇流箱、交直流配电柜及监控系统等设备。

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.

太阳能电池板：太阳能电池板是将太阳辐射转换为电能的核心组件。它们通常由多个太阳能电池组成，可以单独使用或组合在一起以实现所需的发电量和效率。

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.

并网型逆变器：并网型逆变器是将太阳能电池板产生的直流电转换为交流电的设备，其输出的交流电可以和市电的频率及相位同步，因此输出的交流电可以回到市电。

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.

太阳能控制器：控制太阳能电池板对蓄电池充电以及蓄电池给太阳能逆变器负载供电的自动控制设备。它对蓄电池的充、放电条件加以规定和控制，并按照负载的电源需求控制太阳电池组件和蓄电池对负载的电能输出。

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.

电池组：电池是太阳能发电系统的储能设备，可以在太阳能电池板无法产生足够的电力时提供备用电源。常用的太阳能发电系统电池包括铅酸电池和锂离子电池。

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.

电缆线：电缆线用于连接太阳能电池板、逆变器、电池和太阳能控制器等组件，以便它们之间传输电能和信号。电缆线的选择和安装质量对太阳能发电系统的效率和安全性都有很大的影响。电缆线应该具有足够的导电性、耐高温、耐腐蚀和耐磨损等特性，以确保系统的正常运行和长期稳定性。

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：用于支撑固定太阳能电池板，通常分为屋顶支架和地面支架。屋顶支架分为平面支架和斜面支架两种，其中平面支架适用于平顶或轻型屋顶，而斜面支架适用于倾斜屋顶；地面支架分为固定式和可调式两种，其中固定式支架适用于平坦地面，而可调式支架可根据地形和太阳的位置进行调整，使太阳能电池板的角度和方向能够大化地接受太阳辐射能，提高发电效率。

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.
