Non-Conventional Energy Sources: A Sustainable Future by G.D. Rai

• Photovoltaic (PV) Cells: Directly convert sunlight into electricity. Used in everything from rooftop panels to massive solar farms.
• Solar Thermal Systems: Use mirrors or lenses to concentrate sunlight, generating heat that drives steam turbines for electricity (Concentrated Solar Power, CSP) or provides hot water for residential use.

Conclusion
