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
