分布式光伏发电系统又称分散式发电或分布式供能，是指在用户现场或靠近用电现场，配置较小的光伏发电供电系统，以满足特定用户需求，支持现在配电网的经济运行，或者同时满足这两个方面要求。那么分布式光伏发电量怎么计算？

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、分布式光伏发电量计算

1、 Distributed photovoltaic power generation calculation

1.全年峰值光照时数

1. Annual peak light hours

全年峰值光照时数=每日平均峰值光照时数×365天=4.42×365=1613.3小时

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

2.总峰值日照时时数

2. Total peak sunshine hours

如果一块电池板的生命周期为25年，那么它的整个使用年限的总峰值日照时时数为：

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

总峰值光照时数=年峰值光照时数×使用年限16133小时×25年=40332.5小时

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

3、每瓦发电总量

3. Total power generation per watt

假如我们将光伏电站建在地势开阔，周围几乎没什么遮挡物的庭院内。安装光伏组件的方式采用固定式支架进行安装，安装光伏组件的环境也可以满足朝向南面、佳仰角35°的条件。则影响光伏组件发电效率的安装方式系数为1，周围的环境系数为1.15，电池组件生命周期综合发电效率系数0.81。则可估算出光伏组件在整个生命周期内每瓦电池板的总发电量。

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.

每瓦发电总量=总峰值光照时数×安装方式系数×环境系数×综合发电效率系数÷1000

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

每瓦发电总量=40332.5小时×1×1.15×0.81÷1000=37.57度（千瓦时）

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

4、总发电量

4. Total power generation

假如我们的装机容量为20千瓦，则可以通过上面的方式计算出总的发电量：

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

总发电量=每瓦总发电量*装机容量

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

总发电量=37.57×20×1000=751400度（千瓦时）。

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

此外您要知道，光伏组件实际安装时，需要的面积要比计算面积要大些，至于具体大多少，要根据光伏组件实际布局方案来确定。更多相关内容就来我们网站http://www.zdnygf.com进行咨询了解吧！

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.zdnygf.com Consult and understand!
