What are the Basic Parameters of Custom Solar Panels?

Custom Solar Panels have several basic parameters, rated power (Pmax), efficiency (η), open circuit voltage (Voc), short circuit current (Isc), peak voltage (Vmpp), and peak current (Impp).

Custom Solar Panel
                                          
Their definitions are as follows:
Rated power (Pmax): indicates the power generated by the maximum power point voltage when the custom solar panel is at the standard ambient temperature (STC, ie, the atmospheric mass is 1.5, ambient temperature is 25 ° C, the light radiation intensity is 1000 W/m 2 );

Efficiency (η): represents the photoelectric conversion efficiency of the silicon wafer inside the custom solar panel, such as an efficiency of 16.5%, which means that the silicon wafer can generate 165 W of electricity per square meter;

Open circuit voltage (Voc): indicates the voltage across the positive and negative terminals (custom solar panel's no-load voltage) when the solar panel is open at standard ambient temperature;

Short-circuit current (Isc): indicates the short-circuit current generated by short-circuit between the positive and negative terminals of the solar panel when the panel is at the standard ambient temperature;

Peak voltage (Vmpp): indicates the operating voltage of the customized solar panel at the maximum power point (the highest voltage in strong light) when the panel is at the standard ambient temperature;

Peak current (Impp): Indicates the operating current corresponding to the operating voltage of the solar panel at the maximum power point when the panel is at the standard ambient temperature.

Evolution of Silicon Wafer Size

图片
Silicon wafers are divided into semiconductor wafers and photovoltaic wafers according to their uses. Photovoltaic silicon wafers can be single crystal silicon or polycrystalline silicon, and semiconductor silicon wafers can only be single crystal silicon. The biggest difference between the two is that the content and purity of silicon are different. The conversion efficiency of monocrystalline silicon is generally about 18.5%~25%, and the conversion efficiency of polycrystalline silicon wafer is about 17.3%. Correspondingly, monocrystalline silicon solar cells have higher photoelectric conversion efficiency than polycrystalline silicon solar cells.                                                                                        Over the years, the silicon  wafer size  has experienced a process from small to large. The increase in silicon wafer size and the continuous progress of photovoltaic technology have promoted the cost reduction and efficiency improvement of the entire pho

Trends of over 30 Solar Photovoltaic Companies (1)

Although the "global epidemic resistance" is still the main theme in April, it is equally difficult to stop the pace of solar photovoltaic capacity expansion. Enterprises have successively issued announcements to lay out from various directions on the industrial chain such as silicon materials, silicon wafers, solar cells, and solar modules.   However, in the face of the epidemic sweeping the globe, new problems are facing solar photovoltaic people. Companies have to consider how to balance the contradiction between huge capacity and reduced demand? How to survive in a crisis environment?   Domestically, thanks to the joint efforts of the people across the country, the epidemic situation in China has been basically controlled. With the start of solar photovoltaic projects in various provinces in the country, new domestic solar photovoltaic installations are still worth looking forward to this year.                                                                         Custom
