Can you explain the difference between photovoltaic and solar thermal energy ?
Solar energy harnesses the power of the sun to generate electricity or heat. Two major categories are photovoltaic (PV) and solar thermal systems, which differ in their conversion processes, applications, storage capabilities, efficiencies, and costs. PV systems convert sunlight directly into electricity using semiconductor materials like silicon, while solar thermal systems capture the sun's heat to warm a fluid, usually water or air, which then provides heat or generates electricity. PV is mainly used for generating electricity, and solar thermal is used for both heating and electricity generation. Solar thermal systems can more readily incorporate thermal storage solutions, while PV systems typically require battery storage for off-grid applications. The cost and affordability depend on the specific application and location, with PV becoming increasingly competitive in recent years.
