選擇合格的光伏發(fā)電產(chǎn)品是獲得良好收益的前提，但近幾年隨著光伏發(fā)電市場火爆，很多不良的問題也呈現(xiàn)出來，產(chǎn)品質(zhì)量問題服務問題影響了光伏發(fā)電市場發(fā)展，本文天合光能公司就為大家分享光伏新能源發(fā)電量受到哪些因素的影響。

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、光伏組件的安裝角度

1、 Installation angle of photovoltaic modules

光伏組件是影響發(fā)電量的較核心因素，光伏組件的轉(zhuǎn)換率越高發(fā)電效果越好。光伏組件安裝時要盡量面向太陽輻射量較大的角度和方向，安裝角度一般是當?shù)氐木暥燃?度，安裝的方面角一般是正南稍偏西一點。

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、逆變器的電壓范圍

2、 Voltage range of inverter

逆變器電壓范圍越寬，發(fā)電量越高。室外安裝時，逆變器上面要裝防雨防曬蓬，避免陽光直射和雨水浸泡。逆變器不直接暴露在太陽或其它熱源下。逆變器須放在一個空氣流通的空間，逆變器分為強制風冷和自然散熱兩種，逆變器本身是一個發(fā)熱源，所有的熱量都要及時散發(fā)出來，不能放在一個封閉的空間，否則溫度會越升越高。

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、系統(tǒng)配置標準化

3、 System configuration standardization

1.減少損耗

1. Reduce loss

線路損耗，直流光伏線盡可能短，逆變器和電表之間距離也要短。系統(tǒng)的直流、交流回路的線損要控制在5%以內(nèi)。為此，設(shè)計上要采用導電性能好的導線，導線需要有足夠的直徑。施工不允許偷工減料。系統(tǒng)維護中要特別注意接插件以及接線端子是否牢固。

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.電站的灰塵損失

2. Dust loss of power station

組合損失，凡是串連就會由于組件的電流差異造成電流損失；凡是并連就會由于組件的電壓差異造成電壓損失；組合損失可以達到8%以上，工程建設(shè)標準化協(xié)會標準規(guī)定小于10%。為了減少組合損失，應該在電站安裝前嚴格挑選電流一致的組件串聯(lián)。組件的衰減特性盡可能一致。根據(jù)標準規(guī)定，太陽電池組件的較大輸出功率在規(guī)定條件下試驗后檢測，其衰減不得超過8%，隔離二極管有時候是必要的。

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.
