光伏在我们的日常生活中已经不再陌生,小到玩具、中有太阳能路灯、照明、太阳能手机充电器等而现在较火的是光伏赚钱。各地都有光伏发电、光伏养老在我们身边出现。光伏发电系统已经很成熟并全面推广安装。使用寿命25年以上。

现如今家庭家用电器越来越多消耗电量也越来越大,诸多企业用电消耗更大每月电费较高,有光伏发电以后每月再也不用担心高昂的工业用电电价了。这里用电不但不花钱而且还能赚钱。让居民家庭有更好更稳定收益项目,让企业屋顶不再浪费让企业有更好的投资回报项目,实实在在的收益。

分布式光伏发电特点
1、输出功率相对较小。一般而言,一个分布式光伏发电项目的容量在数千瓦以内。与集中式电站不同,光伏电站的大小对发电效率的影响很小,因此对其经济型的影响也很小,小型光伏系统的投资收益率并不会比大型的低。
2、无污染,环保效益突出。分布式光伏发电项目在发电过程中,没有噪声,也不会对空气和水产生污染。
3、能够在一定程度上环节局地的用电紧张状况。但是,分布式光伏发电的能量密度相对较低,每平方米分布式光伏发电系统的功率仅约100瓦,再加上适合安装光伏组件的建筑屋顶面积有限,不能从根本上解决用电紧张问题。
4、可以发电用电并存。大型地面电站发电是升压接入输电网,仅作为发电电站而运行;而分布式光伏发电是接入配电网,发电用电并存,且要求尽可能地就地消纳。
分布式 光伏发电项目应用
1.工业应用
特别是在用电量比较大、网购电比较高的工厂,通常厂房屋顶面积很大,屋顶开阔平整,适合安装光伏阵列;同时由于用电负荷较大,分布式光伏发电可以做到就地消纳,抵消一部分网购电量,从而节省用户的电费。
2.商业应用
与工业区的作用效果雷士,不同之处在于商业建筑多为水泥屋顶,更有利于安装光伏阵列,但是往往对建筑美观性有要求,按照商厦、写字楼、酒店、会议中心等服务业的特点进行安装。用户负荷性一般表现为白天较高、夜间较低,能够较好的匹配光伏发电的特性。
3.居民应用
居民区有大量的可用屋顶,包括自有住宅屋顶、蔬菜大棚、鱼塘等,居民区往往处在公共电网的末梢,电能质量较差,在居民区建设分布式光伏系统可提高用电保障率和电能质量。

光伏发电收益分为以下几种模式
1.自发自用余电上网
分布式光伏发电赚钱收益=光伏发电补贴+光伏发电自用电价+余电上网电价。
2.全额上网
分布式光伏发电赚钱收益=光伏发电补贴+上网电量。
3.自发全用
分布式光伏发电赚钱收益=光伏发电补贴+自用电价。

Photovoltaic is no longer strange in our daily life, ranging from toys to solar street lamps, lighting, solar cell phone chargers, etc. now the hot thing is photovoltaic to make money. Photovoltaic power generation and photovoltaic pension appear around us everywhere. Photovoltaic power generation system has been very mature and fully promoted and installed. The service life is more than 25 years.

Nowadays, more and more household appliances consume more and more electricity. Many enterprises consume more electricity, and the monthly electricity charge is higher. After photovoltaic power generation, there is no need to worry about the high industrial electricity price every month. Electricity here not only costs nothing, but also makes money. Let the resident families have better and more stable income projects, let the enterprise roof no longer waste, and let the enterprise have better investment return projects and real income.

Characteristics of distributed photovoltaic power generation

1. The output power is relatively small. Generally speaking, the capacity of a distributed photovoltaic power generation project is less than several kilowatts. Different from centralized power stations, the size of photovoltaic power stations has little impact on power generation efficiency, so it has little impact on its economy. The return on investment of small photovoltaic systems will not be lower than that of large ones.

2. No pollution, outstanding environmental benefits. The distributed photovoltaic power generation project has no noise and will not pollute air and water during power generation.

3. To a certain extent, it can reduce the local power shortage. However, the energy density of distributed photovoltaic power generation is relatively low. The power of distributed photovoltaic power generation system per square meter is only about 100 watts. In addition, the roof area of buildings suitable for Installing Photovoltaic modules is limited, which can not fundamentally solve the problem of power shortage.

4. Power generation and electricity consumption can coexist. The power generation of large-scale ground power station is connected to the transmission network by step-up, and only operates as a power station; Distributed photovoltaic power generation is connected to the distribution network, power generation and consumption coexist, and it is required to be consumed locally as much as possible.

Application of distributed photovoltaic power generation project

1. Industrial application

Especially in factories with large power consumption and high online power purchase, the roof area of the plant is usually large, and the roof is open and flat, which is suitable for the installation of photovoltaic arrays; At the same time, due to the large power load, distributed photovoltaic power generation can be consumed locally to offset part of the online purchase power, so as to save users' electricity charges.

2. Commercial applications

The difference between Rex and industrial zone is that commercial buildings are mostly cement roofs, which is more conducive to the installation of photovoltaic arrays, but they often have requirements for architectural aesthetics, which are installed according to the characteristics of commercial buildings, office buildings, hotels, conference centers and other service industries. The user load is generally higher during the day and lower at night, which can better match the characteristics of photovoltaic power generation.

3. Residential applications

There are a large number of available roofs in residential areas, including self owned residential roofs, vegetable greenhouses, fish ponds, etc. residential areas are often at the end of the public power grid, and the power quality is poor. The construction of distributed photovoltaic system in residential areas can improve the power guarantee rate and power quality.

Picture

The revenue of photovoltaic power generation is divided into the following modes:

1. Self generated surplus power on the Internet

Profit from distributed photovoltaic power generation = photovoltaic power generation subsidy + photovoltaic power generation self use price + residual power on grid price.

2. Full Internet access

Profit from distributed photovoltaic power generation = photovoltaic power generation subsidy + on grid power.

3. Spontaneous full use

Profit from distributed photovoltaic power generation = photovoltaic power generation subsidy + self use electricity price.
