उत्तर
Solar energy devices use two primary forms of energy from the sun:
-
Light Energy: Utilized in solar photovoltaic (PV) cells to convert sunlight directly into electricity.
-
Heat Energy: Harnessed in solar thermal devices, such as solar water heaters, solar cookers, and concentrated solar power (CSP) systems, to generate heat or electricity.
