太阳能电池板发电原理:

太阳能电池板是通过吸收太阳光,将太阳辐射能通过光电效应或者光化学效应直接或间接转换成电能的装置,大部分太阳能电池板的主要材料为“硅”,太阳能电池板是太阳能发电系统及太阳能灯具中的核心部分,太阳能电池板的作用是将太阳能的光能转化为电能后,输出直流电存入蓄电池中,其转换率和使用寿命是决定太阳能电池是否具有使用价值的重要因素。

太阳能电池板在发电系统的应用:


家用并网太阳能光伏发电系统是采用太阳能板吸收太阳能资源产生低压直流电能(DC24V/CDC48V),然后通过并网逆变器把太阳能板产生的低压直流电(DC24V/DC48V)转换成符合市电电网要求的交流电(AC220V/AC380V)之后直接接入国家公共电网。通过上网电表计算家庭用户太阳能系统产生的电量,卖给国家电网,上网电价执行国家相关政策。家庭用户再从国家电网购买电量供家庭使用,从国家电网购买的电量由下网电表计算。即上、下网电量分开结算,电价执行国家相关政策。

家用并网太阳能发电系统主要由太阳能板、防雷保护汇流箱、并网逆变器及安装支架组成。家用太阳能发电系统的太阳能板一般安装自家楼顶上,或者周边空旷地区,占地面积约为10平方米/KW。并网逆变器放在室内干燥通风处。家用并网太阳能发电系统由于安装地点分散也叫分布式光伏发电。

离网太阳能光伏发电是指太阳能光伏发电不与电网连接的发电方式,典型特征为需要蓄电池来储存夜晚用电的能量。离网太阳能光伏发电在民用范围内主要用于边远的乡村、牧区、海岛、高原、沙漠的农民提供照明、收到电视、收听广播等的基本生活用电;在工业范围内主要用通讯、卫星广播电视中继站、太阳能水泵、航标灯、输油输气管道阴极保护、气象台站、公路道班以及边防哨所等提供电源,在具备风力发电和小水电的地区还可以组成混合发电系统,如风力发电、太阳能发电补光系统等。


绿电太阳能电池板的特点:


☆ 电池片

Principle of solar panel power generation:


Solar panels are devices that directly or indirectly convert solar radiation energy into electrical energy through photoelectric effect or photochemical effect by absorbing sunlight. The main material of most solar panels is "silicon". Solar panels are solar power generation systems and solar energy. The core part of the lamp, the function of the solar panel is to convert the light energy of the solar energy into electric energy, and then store the direct current in the storage battery. The conversion rate and service life of the solar cell are important factors that determine whether the solar cell has the value of use.


Application of solar panels in power generation systems:


The home grid-connected solar power system uses solar panels to absorb solar resources to generate low-voltage DC power (DC24V/CDC48V), and then uses grid-connected inverters to convert the low-voltage DC power (DC24V/DC48V) generated by the solar panels to meet the requirements of the mains grid After alternating current (AC220V/AC380V), it is directly connected to the national public grid. The electricity generated by the solar energy system of household users is calculated through the on-grid electricity meter and sold to the State Grid. The on-grid electricity price is in accordance with relevant national policies. Household users then purchase electricity from the State Grid for household use, and the electricity purchased from the State Grid is calculated by the off-grid meter. That is to say, the online and offline electricity will be settled separately, and the electricity price will follow the relevant national policies.


The home grid-connected solar power generation system is mainly composed of solar panels, lightning protection combiner boxes, grid-connected inverters and mounting brackets. The solar panels of the household solar power generation system are generally installed on the roof of their own buildings or in the surrounding open areas, covering an area of about 10 square meters/KW. The grid-connected inverter is placed in a dry and ventilated place indoors. The home grid-connected solar power generation system is also called distributed photovoltaic power generation due to the scattered installation locations.


Off-grid solar photovoltaic power generation refers to a power generation method in which solar photovoltaic power generation is not connected to the power grid. The typical feature is that batteries are needed to store the energy used at night. Off-grid solar photovoltaic power generation is mainly used for civilian purposes in remote villages, pastoral areas, islands, plateaus, and deserts to provide basic household electricity for lighting, receiving television, and listening to radio; in the industrial area, it mainly uses communications and satellites. Radio and television relay stations, solar water pumps, navigation lights, cathodic protection of oil and gas pipelines, meteorological stations, highways and border posts, etc. provide power. In areas with wind power and small hydropower, hybrid power generation systems, such as wind power, Solar power generation supplementary light system, etc.


Features of Green Power Solar Panel:


☆ Cell


Adopt high-efficiency (polycrystalline silicon above 17.5%, monocrystalline silicon above 19%) imported A-level solar chip packaging to ensure sufficient power generation from solar panels.


☆ Glass


Using low-iron tempered suede glass with a thickness of 3.2mm, the light transmittance is over 97% in the wavelength range of the solar cell's spectral response (320-1100nm), and it has a high reflectivity for red-infrared light greater than 1200nm. This glass is able to withstand the sun's ultraviolet radiation, and the light transmittance will not decrease.


☆ EVA


A high-quality EVA film layer with a thickness of 0.78 mm added with anti-ultraviolet agent, antioxidant and curing agent is used as the connecting agent between the sealing agent of the solar cell sheet and the glass and TPT.


☆ TPT


The back cover of the solar cell, a fluorine plastic film, is white, which reflects sunlight, so the efficiency of the module is slightly improved, and because of its higher infrared emissivity, it can also reduce the working temperature of the module. Conducive to improving the efficiency of components. Of course, this fluoroplastic film firstly has the basic requirements of aging resistance, corrosion resistance, and gas impermeability required by solar cell packaging materials.


☆ Border


The aluminum alloy frame used has high strength and strong resistance to mechanical impact. Anti-oxidation, anti-corrosion, good protection of laminated components, play a certain role of sealing and supporting
