Solar energy is the energy received from the sun, utilized in various forms such as passive and active solar energy, photovoltaic power, solar thermal energy, and concentrated solar power. It offers numerous advantages including being renewable, eco-friendly, and reducing electricity bills, while facing challenges like high storage costs and dependency on weather conditions. Various methods and technologies are employed to harness solar energy effectively.

1. SOLAR ENERGY

2. What is solar energy ?
• Solar energy is the energy received by
the earth from the sun.
• Solar energy is in the form of solar
radiation, which makes the production
of solar electricity.

3. Types of Solar Energy
• Passive Solar Energy
• Active Solar Energy
• Photovoltaic Solar Power
• Solar Thermal Energy
• Concentrated Solar Power

4. Passive Solar Energy
• Passive Solar Energy is a method in
which solar energy is harnessed in its
direct form without using any
mechanical devices.
• Drying Clothes in daylight is an example
of using solar energy passively.

5. Active Solar Energy
• Active Solar Energy employs mechanical
or electrical equipment for functioning
and increase system efficiency.
• For example water pumps are used to
circulate water through the active solar
energy water heating system.

6. Solar thermal Energy
• Solar Thermal Energy is the heat
energy derived from incident solar
energy (sunlight). This energy is used
by the Solar Heating Panels.
• Electricity generated using solar
energy commonly known as Solar
Thermal Electricity.

7. Photovoltaic Energy
• Photovoltaic cells/ solar cells convert
solar energy into electric energy. The
energy generated is termed as
Photovoltaic energy.

8. Concentrated Solar Energy
• Concentrated Solar Power is a branch of
Solar Thermal Energy which is used to
generate solar power electricity.
• Electricity is produced on a large scale
by using this technology.
