            離網型光伏發電系統也被叫做獨立光伏發電系統,它能夠不依賴電網而獨立運行,將光能轉化為電能,可以有效解決因缺電、停電等帶來的難題。由于離網型光伏發電系統不受地域的限制,所以它的使用很廣泛,只要有陽光照射的地方就可以安裝使用,能夠實現“有光就有電”。離網型光伏發電系統非常適合偏遠無電網的地區使用,同時也可以作為經常停電地區的應急發電設備。

             發電原理 
            晶體硅n/p型太陽電池的工作原理:當p型半導體與n型半導體緊密結合連成一塊時,在兩者的交界面處就形成p-n結。當光電池被太陽光照射時,在p-n結兩側形成了正、負電荷的積累,產生了光生電壓,形成了內建電場,這就是"光生伏特效應"。從理論上講,此時,若在內建電場的兩側面引出電極并接上適當負載,就會形成電流,負載上就會得到功率。離網型光伏發電系統的電池組件就是利用半導體材料的電子學特性實現P-V轉換的固體裝置。

            Off-grid photovoltaic power generation system is also called independent photovoltaic power generation system, which can operate independently without relying on the power grid and convert light energy into electricity, which can effectively solve the problems caused by power shortage and power failure. Because off-grid photovoltaic power generation system is not restricted by the region, it is widely used. As long as there is sunlight, it can be installed and used, and it can realize "there is light, there is electricity". Off-grid photovoltaic power generation system is very suitable for remote areas without power grid use, but also can be used as an emergency power generation equipment in areas with frequent power outages.

            Principle of power generation

            The working principle of crystalline silicon n/p solar cells: when the P-type semiconductor and the N-type semiconductor are closely combined into a piece, at the interface of the two forms a P-N junction. When the photocell is irradiated by the sunlight, the accumulation of positive and negative charges is formed on both sides of the p-n junction, generating the photogenerated voltage and forming the built in electric field, which is the "photogenerated volt effect". Theoretically, at this point, if the leading electrodes on the two sides of the built in field are connected to an appropriate load, a current will be formed, and power will be generated on the load. The battery module of off-grid photovoltaic power generation system is a solid device that realizes P-V conversion by utilizing the electronic properties of semiconductor materials.

            Composition of system

            The off-grid photovoltaic system is generally composed of photovoltaic array composed of solar cell modules, solar charge and discharge controller, battery pack, off-grid inverter, DC load and AC load.

            (1) Solar cell assembly

            Solar cell module is the main part of the solar power supply system, is also the most valuable component of the solar power supply system, its role is to convert the solar radiation energy into direct current energy;

            (2) Solar charge and discharge controller (also known as "photovoltaic controller")

            Solar charging and discharging controller is also known as "photovoltaic controller", its role is to regulate and control the electric energy generated by the solar cell module, charge the battery to the maximum extent, and play the role of over-charge protection and over-discharge protection of the battery. Where the temperature difference is large, the photovoltaic controller should have the function of temperature compensation.

            (3) Storage battery sets

            Store the energy generated by solar panels during the day for use when there is no light.

            (4) Off-grid inverter

            Off-grid inverter is the core component of off-grid power generation system, which is responsible for converting DC to AC for AC load. In order to improve the overall performance of the photovoltaic inverter power generation system and ensure the long-term stable operation of the power station, the performance index of the inverter is very important.
