Semiconductor materials are used to make PV cells. A semiconductor is a substance that has both insulator as well as conductor characteristics. At very low temperatures, semiconductors behave as insulators, and their conductivity increases as the temperature rises. At normal temperatures, a semiconductor's electrical.

In essence, a PV module is an individual power generation unit made up of photovoltaic cells, while a PV array refers to many PV modules combined together to provide greater power. In other words, a PV module is a small electricity generator, whereas a PV array is a small power station. Basically, the choice between PV modules and arrays depends on the power needs. Small
Customer ServiceA photovoltaic array – solar array, is a collection of photovoltaic (PV) modules or solar panels that are interconnected to generate electricity from sunlight. These modules consist of multiple solar cells that convert sunlight
Customer ServiceThe PV array is composed of solar modules. Each module contains a matrix of solar cells connected in series and parallel to satisfy the terminal properties of the whole generator. Accordingly, the solar cell is the basic element in the PV generator. This element is the basic solar radiation converter into electricity.
Customer ServiceWhen light shines on a photovoltaic (PV) cell – also called a solar cell – that light may be reflected, absorbed, or pass right through the cell. The PV cell is composed of semiconductor material; the "semi" means that it can conduct electricity better than an insulator but not as well as a good conductor like a metal. There are several
