2. INTRODUCTION
 Solar light and solar pump are based on the
principle of photovoltaic system.
 Solar photovoltaic system or PV system is an eco-
friendly technology developed to transform the
solar energy into electricity through solar panels.
 A PV system comes in various sizes and is useful
in solar water heating, ventilation, pumping,
lighting, etc.

3. SOLAR LIGHT
 A solar light , also known as solar lantern , is a lighting
system composed of an LED lamp , solar panels , battery
, charge controller & may be an inverter.
 Solar Panel collects the solar energy & converts it to DC
power. The size of solar panel depends on various
factors.
 A lithium rechargeable battery is required to store the
energy which will power the LED in dusk.
 Charge controller will manage the power going to & from
the battery to prevent over charging or discharging.

4. UNDERSTANDING THE PROCESS

5. APPLICATION
Street lights
Garden solar lamps
Solar boat lighting
In rural India and remote regions of the
world , solar lamps are being used to
replace kerosene lamps.

6. SOLAR PUMPING
 Solar powered pumps run on electricity generated
by PV panels or the radiated thermal energy
available from collected sunlight as opposed to grid
electricity or diesel run water pumps.
 Generally, these consist of a solar panel array ,
charge controller, DC/AC water pump, fuse
box/breakers, electrical wiring & a water storage
tank.
 With the cost of diesel and electricity rising
constantly, solar water pumps are the best
alternative for rural regions.

7. MERITS
