Renewable Energy Systems (Solar & Wind)

Renewable Energy Systems use natural resources like sunlight and wind to generate electricity. These sources are clean, sustainable, and eco-friendly.

Solar Energy System:- Solar Energy converts sunlight into electricity using solar panels.

• Main Components
  • Solar Panels (PV modules) – Convert sunlight into DC electricity
  • Charge Controller – Regulates battery charging
  • Battery – Stores energy (optional)
  • Inverter – Converts DC to AC power
  • Load/Grid – Uses or exports electricity
• Working (Simple)

Sunlight → Solar Panel → DC Power → Inverter → AC Power → Home/Industry

• Advantages
  • Pollution-free
  • Low maintenance
  • Ideal for rooftops & remote areas
  • Reduces electricity bills
• Limitations
  • Works only in sunlight
  • High initial cost
  • Needs large area for high power

Wind Energy System:- Wind Energy uses wind turbines to convert wind’s kinetic energy into electricity.

• Main Components
  • Rotor Blades – Capture wind energy
  • Nacelle – Contains gearbox & generator
  • Tower – Supports turbine at height
  • Generator – Produces electricity
  • Transformer – Steps up voltage
• Working (Simple)

Wind → Rotating Blades → Generator → Electrical Power → Grid

• Advantages
  • Clean & renewable
  • Low operating cost
  • Suitable for large-scale power
• Limitations
  • Depends on wind speed
  • Noise & visual impact
  • Needs open land/locations
