Solar Cell Panel Module

The flexibility of the modular pv system allows designers to create solar power systems that can meet a wide variety of electrical needs.

Photovoltaic modules consist of pv cell circuits sealed in an environmentally protective laminate and are the fundamental building blocks of pv systems. The solar cells absorb sunlight as a source of energy to generate electricity. When solar cells are halved their current is also halved so resistive losses are lowered and the cells can produce a little more power. Half cell modules have solar cells that are cut in half which improves the module s performance and durability.

Each cell produces approximately 1 2 a volt and a solar module can have any number of solar cells. For example a 12 v panel module will have 36 cells connected in series and a 24 v panel module will have 72 pv cells connected in series. Traditional 60 and 72 cell panels will have 120 and 144 half cut cells respectively. A solar cell is the basic building block of a solar module.

An array of modules are used to supply power to buildings. With solar cell and module capacity in malaysia thailand and vietnam trina solar said it would expand solar cell capacity by a further 2 5gw at facilities outside china.

Photovoltaic panels include one or more pv modules assembled as a pre wired field installable unit.
