1. What are Photovoltaic Modules?

Photovoltaic (PV) modules, commonly referred to as solar panels, are a combination of solar cells that convert sunlight into electricity. These solar cells are made from semiconductor materials such as silicon, and the PV modules are integral components of a solar power system designed to harness solar energy and produce clean, renewable electricity.

2. Types of Photovoltaic Modules

There are several types and designs of PV modules available on the market:

• Crystalline Silicon Modules: These include monocrystalline and polycrystalline silicon panels, which are known for their efficiency and durability.

• Thin-Film Modules: Comprised of amorphous silicon, CIGS, or CdTe, these panels are lightweight, flexible, and typically have lower efficiency.

• Bifacial Modules: Designed to generate power from both sides of the panel, these modules increase power output.

• Building-Integrated Photovoltaics (BIPV): These PV modules are integrated into building materials, offering architectural and aesthetic benefits.

3. Applications of Photovoltaic Modules

PV modules are utilized across various solar power applications:

• Residential solar power systems

• Commercial and industrial solar installations

• Utility-scale solar power plants

• Rooftop and ground-mounted solar systems
