1. What are Photovoltaic (PV) Modules?

Photovoltaic (PV) modules, also known as solar panels, are composed of interconnected solar cells that convert sunlight into direct current (DC) electricity. Made from a variety of semiconductor materials, PV modules are essential components in a solar power system, harnessing solar energy to generate clean, renewable electricity.

2. Types of Photovoltaic (PV) Modules

PV modules are available in various types and designs:

• Crystalline Silicon Modules: Including monocrystalline and polycrystalline silicon panels, known for their efficiency and durability.

• Thin-Film Modules: Made from alternative materials like amorphous silicon, CIGS, or CdTe, these panels are lightweight and flexible.

• Bifacial Modules: Designed to generate electricity from both sides, these modules can produce more power than traditional panels.

• Building-Integrated Photovoltaics (BIPV): Integrated into building materials, these PV modules enhance the aesthetics of the structure.

3. Applications of Photovoltaic (PV) Modules

PV modules find use in a wide range of solar power applications:

• Residential solar power systems
