What is Solar Panel? Solar panels are also known as photo-voltaic solar module, solar plate, solar PV module and solar power panel etc. Solar panels are made up with a bunch of 60-72 solar cells that convert sunlight into electricity. These solar cells are made from an element called, “silicon“. To manufacture solar cells, fragments of silicon are melted together and to reduce the manufacturing and maintenance cost, its edges are cutted off. If we install two or more solar panel together and connect them with solar inverter, solar battery than it become a solar power system that can be used in houses, companies, schools, industries etc. Solar panel is the main part of solar system and all types of solar system (on grid solar system, off grid solar system and hybrid solar system) contains same type of solar panel.

1. About Solar Panel
Solar panel also known as photovoltaic solar module, solar plate and solar power panel. Solar
panels are made up with a bunch of 60-72 solar cells that convert sunlight into electricity. Solar
cells are made up with silicon wafers, a semiconductor.
One or more solar panel makes a solar power system that can be used in houses, companies,
schools, industries etc. Solar panel is the main part of solar system and all type of solar system
(on-grid, off-grid, and hybrid) contains same type of solar panel.
Solar Panel Price
Solar panel price are measured in per watt, if you buy in bulk the price of solar panel cost will
be reduced. Solar panel cost starts from Rs. 25 to Rs. 48 per watt, depending on the quality,
quantity, size, efficiency and brand of solar panel.

2. Types of solar panel
Solar panels available in the market are mainly classified into two types: poly-crystalline solar
panel and mono-crystalline solar panel.
H3 - Difference between Poly-crystalline solar panels and Mono-crystalline solar panels
Poly-crystalline solar panel Mono-crystalline solar panel
• Cost Effective.
• Panel efficiency up to 16%.
• Looks bluish in color.
• It takes more rooftop space.
• Low efficiency in cloudy weather.
• Expensive solar panel.
• Panel efficiency up to 16%.
• Looks black in color.
• It takes less rooftop space.
• Better efficiency even in low light.
Which is best solar panel?
Solar panel efficiency refers to the amount of sunlight converted to electricity in specific area.
Under three types of solar panel technology, mono crystallize are the best in efficiency. Mono
crystalline panels have the highest efficiency of 19%, require less space and are more expensive
than polycrystalline. A 100-watt poly and mono crystalline panel will generate the same
amount of power but the mono crystalline panel will take up less space than a polycrystalline
panel.
• Mono crystalline solar panels efficiency – 19%
• Poly crystalline solar panels efficiency– 15%
Solar panel application
Solar lights- Battery-based solar lights are a stand-alone system that will store power from the
solar panel i.e. solar garden light, solar lantern, solar home lights etc. Generally, solar panel for
solar lights starts from 3w to 75w.
On-grid- Generally, 300 watt and above ranted solar panels are used in On grid Solar System.
As the on grid solar systems starts from 1kW (3 Panels).
Off-grid- Off-grid solar system starts from 100w to 100kW. So, 100 watt to 330 watt solar panel
is used in these types of systems.
Hybrid -Generally, 300 watt and above ranted solar panels are used in Hybrid Solar System. As
the Hybrid grid solar systems starts from 3kW (9 Panels).

3. Solar water pump - Solar water pumping range start from 1HP (3 Panels) to 10 HP. So, higher
rating panel are used in these pumps.
Solar AC- The solar AC will be run on solar power and at the same time the solar panel will
charge the battery bank.

light, customers can choose 3 kW solar systems from Kenbrook Solar.
Q. How much does installation cost of solar panel in India?
A. Solar panel installation cost start from Rs. 2 per watt to cost Rs. 10 per watt. Depend upon
capacity of solar system, location and type of solar system.
Q. How much rooftop space required installing solar panel?

6. A. 6 square meter per kilowatt. A 335 watt solar panel size is approximate 1 meter x 2 meter
and 3 panels are used in 1kW Solar System.
Q. Is my roof suitable for solar panel?
A. The first thing that roof should be free of shadow. Solar panels are not laid down directly on
your rooftop, solar panel are takes place on mounting structures which can be customized
according to your rooftop. If there is proper sunlight then yes, solar panels are suitable for any
kind of rooftop.
Q. Can I run a fan directly from solar panel?
A. Yes, DC fan can be run directly on solar panel through charge controller. In case of AC fan,
Inverter is must in solar system because solar system generates DC form of electricity.
Q. Can I go off grid with solar panel?

Q. How much does solar panel maintenance cost?
A. Solar panels are a low-maintenance product however, it is mandatory to regularly clean solar
panels to remove dust particles that accumulate on solar panels.
Q. What is the average lifespan of a solar panel?
A. Solar panels come with 25 years warranty in India. However, the lifespan of a solar panel can
go up to 30 years depending upon brand and quality of solar panel.
Q. Does solar panel work during monsoon?
A. Yes, solar panel will produce relatively less energy during monsoon. Shades, clouds, and
monsoon do affect the performance of solar panels. The rays of the sun falling on the solar
panel are related to the amount of electricity.
Q. How do solar panels work?
A. The sun falling on the solar panels is converted into electricity. This electricity from the solar
panel is in direct current form and since we use alternating current to drive devices in our
home, an inverter is installed to convert this direct current to alternating current.

7. Q. Which is the best solar panel company in India?
A. Tata, Luminous, Havells, Vikram, Waaree, Adani etc are the best solar panel companies in
India.
