Solar Photovoltaic Systems
Solar photovoltaic (PV) systems convert sunlight into electricity through the photovoltaic effect, utilizing solar cells as key components. Various types of solar cells exist, including monocrystalline and thin-film, each with distinct characteristics and efficiencies. The construction of solar modules and arrays allows for scalable power generation, while photovoltaic thermal (PVT) systems enhance performance by producing both electricity and heat. Innovations in solar technologies contribute significantly to sustainable energy strategies.
