2. Introduction to Solar P.V
● Solar P.V is used to harness power from sun by
collecting photon by silicon panel
● Initial cost for installation is high but long term return &
subsidy will lessen cost
● Easy to install, repair and maintain system
● Remote location and tribal region can get access to light
and mobile charging
● Community approach will significantly reduce cost of
installation and repair cost
● Eco Friendly and clean energy system of power
generation

3. Components of Solar P.V
●
Solar Panel: It collects photon from rays striking from
sun via silicon panel with doping of phosphorous.
●
Charge Controller: It is central connection of system
with all supply coming to it from panel, battery, load.
●
Battery: Helps in storage of charge and provides power
to load.
●
Load: Electric bulb or any electric appliances
●
Inverter: It helps to convert a.c to d.c and vice versa.
Especially used in hybrid system or to operate a.c
appliances.

4. Installation of Solar P.V
● Solar Panel is installed on roof tops or areas where
there is plenty of sunshine facing north to south direction
at angle of 30 degree.
● Charge Controller(CC) is central system in which
connection from panel, battery and load comes which
help to maintain safety of system it is also provided with
fuse.
● Battery is most important system which is connected
to CC. The battery should not be completely drained and
excessive use should be avoided.

5. ● Load is connected to CC from where supply is taken to
electric appliances like bulb, t.v, freeze and other
accessories.
● Inverter is used to convert a.c to d.c and vice versa in
hybrid system or to run a.c appliances form d.c power
output. It is connected after load of CC.

6. Repair and Maintenance
● Solar panel has long life so does not require much care
except cleaning of panel and preventing it from dust &
dirt.
● Battery should be given special care it should be kept in
proper ventilated area. There should not be direct
connection from battery to load. In case of acid battery
we should check amount of acid and fill with distill water
in later stage. The user must be provided with
knowledge about depth of discharge and limit up to
which we can use battery.
● Charge Controller is provided with fuse for safety we
need to make sure that all connection is to be made
from panel, battery and load.

7. Solar Business in Rural Areas
● Types of Solar Business in Nepal
- Solar as Trading Business
- Solar as Commodity Business
- Solar as Energy Service Provider

8. Solar as Trading Business
- This is simply done by buying in bulk of solar
materials and selling them in market directly
to clients or local solar firms.
- Unreliable form of solar business rising in
Nepal
- Requires high budget and investment for
starting business
- Purely money oriented system of solar
business

9. Solar as Commodity Business
- 95% of Nepalese business is such form of
business in solar
- Divided into
* Home System which is entirely D.C
* Residential System which can be A.C
hybrid system
* Commercial Back up system for bank,
offices, school, colleges done with energy
audit

10. Solar as Energy Service
Provider
Here solar company owns every components
and provides solar as only service to people.
● Micro Grids
- ABC (Anchor Business Consumer)
There has to be Anchor who needs 24 hrs supply like
telecom tower and chilling Vats. Some Business
potential like photocopy operator, hand tools user,
freeze user as business model. Finally consumers
clustered around installation. The tariffs will be different
for different level of users.

11. ● Nano Grids
This is purely d.c system which best provides
service within range of 100m. It is suitable if
there are 20-30 house in cluster. The energy
service provider will look after installation and
consumer will pay regular tariffs of use.
● Productive End Use
The service provider will install system and
provide business oriented system like freeze,
saw mills, grinding mills for which client will
pay downpayment and monthly tariffs.
