Types of Solar Energy Systems

Photovoltaic (PV) Systems

Photovoltaic systems are the most common type of solar energy systems. They convert sunlight directly into electricity using photovoltaic cells. These cells are made of semiconductor materials, such as silicon, that generate an electric current when exposed to sunlight. There are three main types of PV systems: monocrystalline, polycrystalline, and thin-film.

Thin-film PV panels are made by depositing a thin layer of photovoltaic material onto a substrate. They are lightweight and flexible, allowing for more design versatility. However, they have lower efficiency compared to crystalline silicon panels.

Concentrated Solar Power (CSP) Systems

Concentrated Solar Power systems use mirrors or lenses to concentrate sunlight onto a receiver, which in turn converts it into heat or electricity. There are three main types of CSP systems: parabolic trough, solar power tower, and dish/engine system.
