What is a solar battery?

As a semiconductor, it conducts electric current, exhibiting high electrical and thermal conductivity to convert solar energy into electricity and dissipate the generated heat in the energy conversion process. Therefore, the type of battery is determined by the principle of silicon application.

How does a solar battery work?

Solar elements of p-type and n-type silicon, the so-called heart of the battery, generate electric current due to the flow of electrons caused by sunlight hitting the surface of solar PV cells. The distribution box with a connection block collects the current from solar elements and directs it to the inverter, which converts DC to AC.

Why do solar panels use batteries?

The batteries have the function of supplying electrical energy to the system at the moment when the photovoltaic panels do not generate the necessary electricity. When the solar panels can generate more electricity than the electrical system demands, all the energy demanded is supplied by the panels, and the excess is used to charge the batteries.

What is the operating principle of a solar cell?

Conceptually, the operating principle of a solar cell can be summarized as follows. Sunlight is absorbed in a material in which electrons can have two energy levels, one low and one high. When light is absorbed, electrons transit from the low-energy level to the high-energy level.

What makes a solar PV battery a good choice?

The aluminum frame, as the external part of the battery, protects internal components from environmental influences. Tempered glass, as the top layer of solar PV cells, protects against changing weather conditions and maximizes the penetration of sunlight.

How does a solar cell work?

The distribution box with a connection block collects the current from solar elements and directs it to the inverter, which converts DC to AC. The solar cell working principle is based on the internal photoelectric effect – the formation of an excited electron-hole pair at the p-n junction.
