How much do you know about the specifications of solar photovoltaic panels

1. What are the specifications of solar photovoltaic panels?

There are many sizes of solar photovoltaic panels, mainly depending on the application. If it is used in a power station, a 300W panel is generally used, and the size of the 300W is 1960*990*35 in MM. The small one is 200*90 (mm). Solar photovoltaic power generation system is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. There are two modes of independent operation and grid-connected operation. Independently operating photovoltaic power generation systems require batteries as energy storage devices. They are mainly used in remote areas without grids and areas with scattered populations. The cost of the entire system is high; Save the storage battery, not only can greatly reduce the cost, but also has higher power generation efficiency and better environmental protection performance.

2. Solar panel parameters

Short-circuit current: when the positive and negative poles of the solar cell are short-circuited, the current at this time is the short-circuit current of the battery sheet, and the unit of the short-circuit current is ampere; open-circuit voltage: when the positive and negative poles of the solar cell are not connected to the load, the solar cell The voltage between the positive and negative electrodes is the open circuit voltage, and the unit of the open circuit voltage is volts, generally 0.5~0.7v;

Peak current: peak current is also called the maximum working current unit is ampere; peak voltage: peak voltage is also called the maximum working voltage or the best working voltage. Generally 0.45~0.5v, typical value is 0.48v

3. Solar photovoltaic panels produced by fgnexsolar

The solar photovoltaic panel produced by fgnexsolar adopts half-cut cell technology; new circuit design; has the advantages of lower internal current and lower Rs loss, solar panels have half-cut cell technology; new circuit design; lower internal current, lower Rs Loss; special circuit design, hot spot temperature is greatly reduced; fire safety (Class C, TÜV Rheinland certification, TÜV Rheinland testing standards); anti-power attenuation passed the TÜV Rheinland system withstand voltage test; salt spray corrosion resistance (IEC61701, TÜV Rheinland) Test standard certification); 100% double EL test, which significantly reduces the cracking rate of the module.
