Many cells are combined to form a solar panel.
Advantages:
Produces clean and renewable electricity.
Works even in remote areas without a power grid.
Silent and low maintenance.
Uses:
Supplying electricity to homes, schools, and industries.
Uses:
Powering calculators, street lights, satellites, and small home systems.
Disadvantages:
Expensive to manufacture.
Efficiency depends on sunlight (less effective on cloudy days or at night).
Method:
A group of solar cells arranged together on a panel collects sunlight.
The energy is converted into direct current (DC) electricity, then changed into
alternating current (AC) using an inverter for home or industrial use.
Solar panels are often installed on rooftops or large solar farms.
