QUESTIONS AND RESPONSES

WHAT ARE THE PRIMARY TYPES OF SOLAR ENERGY TECHNOLOGIES?

Solar energy technologies generally encompass two distinct types: photovoltaic (PV) systems and concentrating solar power (CSP) systems. Photovoltaic systems use solar panels to convert sunlight directly into electricity through the photovoltaic effect. This process relies on semiconductor materials, typically silicon, that liberate electrons upon exposure to sunlight, generating electricity. PV systems are ideal for decentralized energy solutions, as they can be installed on rooftops or in remote areas, providing flexibility in energy sourcing.

Concentrating solar power systems, on the other hand, use mirrors or lenses to focus sunlight onto a small area, typically a heat exchanger. This concentrated heat produces steam that drives a turbine connected to a generator, thus creating electricity. CSP systems are often employed on a larger scale, typically suitable for utility-scale solar farms. They require significant land but offer the advantage of thermal storage capabilities, allowing energy generation even when sunlight is not available. Understanding these distinct technologies is vital for appreciating solar energy’s vast potential in addressing global energy concerns.
