选择合格的光伏发电产品是获得良好收益的前提，但近几年随着光伏发电市场火爆，很多不良的问题也呈现出来，产品质量问题服务问题影响了光伏发电市场发展，本文天合光能公司就为大家分享光伏新能源发电量受到哪些因素的影响。

The selection of qualified photovoltaic power generation products is a prerequisite for obtaining good income. However, with the popularity of the photovoltaic power generation market in recent years, many adverse problems have emerged. Product quality problems and service problems have affected the development of the photovoltaic power generation market. In this paper, Trina Solar will share the impact of which factors on the new photovoltaic energy generation capacity.

一、光伏组件的安装角度

1、 Installation angle of photovoltaic modules

光伏组件是影响发电量的较核心因素，光伏组件的转换率越高发电效果越好。光伏组件安装时要尽量面向太阳辐射量较大的角度和方向，安装角度一般是当地的纬度加5度，安装的方面角一般是正南稍偏西一点。

PV modules are the core factor affecting power generation. The higher the conversion rate of PV modules, the better the power generation effect. When installing photovoltaic modules, try to face the angle and direction with large solar radiation. The installation angle is generally the local latitude plus 5 degrees, and the installation angle is generally a little south by west.

二、逆变器的电压范围

2、 Voltage range of inverter

逆变器电压范围越宽，发电量越高。室外安装时，逆变器上面要装防雨防晒蓬，避免阳光直射和雨水浸泡。逆变器不直接暴露在太阳或其它热源下。逆变器须放在一个空气流通的空间，逆变器分为强制风冷和自然散热两种，逆变器本身是一个发热源，所有的热量都要及时散发出来，不能放在一个封闭的空间，否则温度会越升越高。

The wider the inverter voltage range, the higher the power generation. During outdoor installation, the inverter shall be equipped with a rain proof sunscreen to avoid direct sunlight and rain soaking. The inverter shall not be directly exposed to the sun or other heat sources. The inverter must be placed in an air circulation space. The inverter is divided into forced air cooling and natural heat dissipation. The inverter itself is a heat source, and all heat must be emitted in time. It cannot be placed in a closed space, otherwise the temperature will rise higher and higher.

三、系统配置标准化

3、 System configuration standardization

1.减少损耗

1. Reduce loss

线路损耗，直流光伏线尽可能短，逆变器和电表之间距离也要短。系统的直流、交流回路的线损要控制在5%以内。为此，设计上要采用导电性能好的导线，导线需要有足够的直径。施工不允许偷工减料。系统维护中要特别注意接插件以及接线端子是否牢固。

Line loss, the DC photovoltaic line should be as short as possible, and the distance between the inverter and the meter should also be short. The line loss of DC and AC circuits of the system shall be controlled within 5%. For this reason, the conductor with good conductivity shall be used in the design, and the conductor shall have sufficient diameter. No jerry building is allowed. During system maintenance, special attention shall be paid to whether the connectors and terminal blocks are firm.

2.电站的灰尘损失

2. Dust loss of power station

组合损失，凡是串连就会由于组件的电流差异造成电流损失；凡是并连就会由于组件的电压差异造成电压损失；组合损失可以达到8%以上，工程建设标准化协会标准规定小于10%。为了减少组合损失，应该在电站安装前严格挑选电流一致的组件串联。组件的衰减特性尽可能一致。根据标准规定，太阳电池组件的较大输出功率在规定条件下试验后检测，其衰减不得超过8%，隔离二极管有时候是必要的。

Combination loss, the current loss will be caused by the current difference of components in series; In case of parallel connection, voltage loss will be caused due to voltage difference of components; The combined loss can reach more than 8%, and the standard of China Engineering Construction Standardization Association is less than 10%. In order to reduce the combination loss, components with the same current should be strictly selected for series connection before the installation of the power station. The attenuation characteristics of components shall be as consistent as possible. According to the standard, the attenuation of the larger output power of the solar cell module shall not exceed 8% after the test under the specified conditions, and the isolation diode is sometimes necessary.
