分布式光伏發電系統又稱分散式發電或分布式供能，是指在用戶現場或靠近用電現場，配置較小的光伏發電供電系統，以滿足特定用戶需求，支持現在配電網的經濟運行，或者同時滿足這兩個方面要求。那么分布式光伏發電量怎么計算？

Distributed photovoltaic power generation system, also known as distributed power generation or distributed energy supply, refers to the configuration of a small photovoltaic power generation power supply system at or near the user site to meet the needs of specific users, support the economic operation of the current distribution network, or meet both requirements. How to calculate the distributed photovoltaic power generation?

一、分布式光伏發電量計算

1、 Distributed photovoltaic power generation calculation

1.全年峰值光照時數

1. Annual peak light hours

全年峰值光照時數=每日平均峰值光照時數×365天=4.42×365=1613.3小時

Annual peak light hours=daily average peak light hours × 365 days=4.42 × 365=1613.3 hours

2.總峰值日照時時數

2. Total peak sunshine hours

如果一塊電池板的生命周期為25年，那么它的整個使用年限的總峰值日照時時數為：

If the life cycle of a battery panel is 25 years, the total peak sunshine hours of its entire service life are:

總峰值光照時數=年峰值光照時數×使用年限16133小時×25年=40332.5小時

Total peak light hours=annual peak light hours × Service life 16133 hours × 25 years=40332.5 hours

3、每瓦發電總量

3. Total power generation per watt

假如我們將光伏電站建在地勢開闊，周圍幾乎沒什么遮擋物的庭院內。安裝光伏組件的方式采用固定式支架進行安裝，安裝光伏組件的環境也可以滿足朝向南面、佳仰角35°的條件。則影響光伏組件發電效率的安裝方式系數為1，周圍的環境系數為1.15，電池組件生命周期綜合發電效率系數0.81。則可估算出光伏組件在整個生命周期內每瓦電池板的總發電量。

Suppose we build the photovoltaic power station in a courtyard with open terrain and little shelter around. The fixed support is used for the installation of PV modules, and the environment for installing PV modules can also meet the conditions of facing south with a good elevation of 35 °. The installation mode coefficient that affects the power generation efficiency of the PV module is 1, the surrounding environment coefficient is 1.15, and the comprehensive power generation efficiency coefficient of the battery module life cycle is 0.81. Then the total power generation of each watt of solar panel in the entire life cycle of photovoltaic modules can be estimated.

每瓦發電總量=總峰值光照時數×安裝方式系數×環境系數×綜合發電效率系數÷1000

Total power generation per watt=total peak light hours × Installation mode coefficient × Environmental coefficient × Comprehensive generation efficiency coefficient ÷ 1000

每瓦發電總量=40332.5小時×1×1.15×0.81÷1000=37.57度（千瓦時）

Total power generation per watt=40332.5 hours × one × one point one five × 0.81 ÷ 1000=37.57 degrees (kWh)

4、總發電量

4. Total power generation

假如我們的裝機容量為20千瓦，則可以通過上面的方式計算出總的發電量：

If our installed capacity is 20 kilowatts, we can calculate the total power generation in the above way:

總發電量=每瓦總發電量*裝機容量

Total power generation=total power generation per watt * installed capacity

總發電量=37.57×20×1000=751400度（千瓦時）。

Total power generation=37.57 × twenty × 1000=751400 degrees (kWh).

此外您要知道，光伏組件實際安裝時，需要的面積要比計算面積要大些，至于具體大多少，要根據光伏組件實際布局方案來確定。更多相關內容就來我們網站http://www.51dwgw.cn進行咨詢了解吧！

In addition, you should know that the area required for the actual installation of photovoltaic modules should be larger than the calculated area. The specific size should be determined according to the actual layout scheme of photovoltaic modules. More relevant content will come to our website http://www.51dwgw.cn Consult and understand!
