Introduction to Solar Energy Solar energy refers to the radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies, such as solar heating, photovoltaics (PV), solar thermal energy, solar architecture, molten salt power plants, and artificial photosynthesis. It is a renewable and virtually inexhaustible resource, making it a cornerstone of sustainable energy systems. As of 2025, solar energy accounts for approximately 5-6% of global electricity generation, with rapid growth driven by declining costs and technological advancements. The fundamental appeal of solar energy lies in its abundance: the Earth receives about 173,000 terawatts (TW) of solar energy continuously, far exceeding human energy needs. However, challenges such as intermittency (dependence on weather and daylight) and the need for energy storage solutions must be addressed for widespread adoption. Historical Context The concept of harnessing solar energy dates back to ancient civiliz
