One minute to help you understand photovoltaic terminology

Can you understand some specialties in photovoltaic power generation, photovoltaic power station, photovoltaic solar energy and other industries? Now Huangshan Yincha New Energy Technology Co., Ltd. will give you the following introduction

Radiation:

The total solar radiation energy per unit area and per unit time is generally accumulated in one second (1J=1W. s) at one million joules per year, square meter (MJ/Y. ㎡) or one million joules per month, square meter (MJ/M. ㎡).

Sunshine intensity:

The solar radiation power per unit area is generally expressed in W/㎡ or mW/c ㎡. The sunshine intensity of AM 0 exceeds 1300W/㎡, and the standard test condition for solar cells is 1000W/㎡ (equivalent to 100mW/c ㎡).

Solar Cell:

Modules with photovoltaic effect that convert light (Photo) into electricity (Voltaic) are also called PV cells. The electricity generated by solar cells is DC.

Photovoltaic:

PV (photo=light light, voltaics=electricity) is called "clean power generation technology" because it does not produce nitrogen oxides, harmful gases and radioactive waste. PV System refers to a complete system that converts solar energy into electrical energy, which is called solar photovoltaic system or photovoltaic system. It can be classified as independent type, parallel type and hybrid type.

PV Module:

Multiple solar cells are connected in series to boost the voltage, and are packaged with solid materials to facilitate application, which is also called a module (PV Pannel or PV Module).

PV Group Column (PV String):

The samples are connected in series to form a row. The purpose of the array is to increase the voltage. The 10 samples are connected in series with a voltage of 20 volts and 5 amperes. The array voltage is 200 volts and the current is 5 amperes.

PV Array:

Arrays are formed by paralleling multiple groups. The purpose of the array is to increase the current. The array is composed of five series of 200 volt and 5 amperes in parallel. The array voltage is 200 volt and the current is 25 amperes. An array consisting of one group of columns is equivalent to a group of columns.

Stand Along System:

Multiple solar cells are connected in series to boost the voltage, and are packaged with solid materials to facilitate application, which is also called a module (PV Pannel or PV Module).

Grid System:

The PV array output is converted into AC through the converter, which is connected in parallel with the mains or self provided generator. The system does not need to be equipped with a power storage device.

Hybrid System:

The hybrid of independent type and parallel type is also called disaster prevention type because the parallel type system will stop operating when the power supply of the city is stopped due to natural disasters. The hybrid type can be switched to the independent type to continue power supply.
