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

Types of solar energy
4. 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.
Passive Solar Energy has a few applications
which all of us can use (where ever there is
sunlight).
Daylighting
Passive Solar Heating
Passive Solar Cooling
Passive solar energy
5. The Active Solar Energy employs mechanical or electrical
equipment for functioning and increase system efficiency. As
an example water pumps are used to circulate water through
the active solar energy water heating system.
Some Applications of Active Solar Energy which can be very
helpful to all of us.
Active Solar Water Heating
Active Solar Pool Heating
Active Solar Space Heating
Active solar energy
6. Solar Thermal Energy is the heat energy derived from the incident
solar energy (sunlight). This is used by Solar Heating Panels.
Yes, you guessed it right. Solar Thermal Energy does have advantag
like other forms of solar energy.
Solar Water Heating
Solar Pool Heating
Solar Space Heating
These are the common uses of Solar Thermal Energy. By taking
advantage of these you can get plenty of benefits. Electricity can be
generated using solar energy commonly this is known as
Solar Thermal Electricity
Solar thermal energy
7. The Energy generated by incident solar energy (light) into
electricity is termed as Photovoltaic Solar Power. This is done
using Photovoltaic Solar Cells.
Every one of us can get the benefits of the applications of
photovoltaic solar power.
Solar Electricity
Photovoltaic Solar Lighting
Photovoltaic Cooling
Photovoltaic energy
8. Concentrated Solar Power is a branch of Solar Thermal Energy whic
is used to generate solar power electricity.
Electricity is produced on a large scale by using this technology. Th
technology is not in either of our scope. But we can surely get its
benefits from a renewable energy supplier or green power from the
electricity supply company.
Knowing about the different solar energy types can be very helpful.
You can use this knowledge in order to decide in what way the sola
energy can be used for your advantage. Come what may you will
always get the benefit of any types of solar energy and help you
contribute to make this world a better place!
Concentrated solar energy
9. A solar power plant of the size 10–100 kW
depending on the load demand, is preferable
Particularly with a liberal subsidy to raise the
quality of life of the people subjected to
poverty in these areas.
Centralized power generation and distribution,
individual DLS (domestic lighting systems) are
also common in many rural unelectrified
houses.

entirely in the USA from raw silicon to
completed solar panels. This process involves
four main steps: crystal growing, wafering,
solar cell production and solar panel assembly.
