• Solar power is the conversion of sunlight into
electricity, through directly using photovoltaic (PV).
Photovoltaic convert light into electric current
using the photoelectric effect.
What is Solar Power System
• To Reduce Gaseous emission and thus save the
ozone layer.
• To Reduce Grid dependency
• To Empower remote areas.
Why We Prefer Solar Energy
• Reduction in Air Pollution
• Health and Safety Concerns
• Low Maintenance Cost
• Reliable Source
Benefits of Solar Power
1.Charge Controller
2.Solar Panel (PV Panel)
3.Inverter
4.Battery
HOW THE SOLAR SYSTEM FIT TOGETHER
• Where to use the solar system, how about the solar irradiation condition in
the area.
• Total loading power(KW), and daily consumption (KWH).
• What will be the system output voltage required?
• Working time on each day for the solar system.
• System Backup days in continuous raining and cloudy condition.
Factors For Designing a Solar Power
System
• An off grid or stand along solar PV system is when solar PV system
is not connected to the utility grid and we are producing own
electricity via solar is called off-grid solar system

of radiant energy through a
medium).
• The average irradiation of my area is
1069 W/m²
IRRADIANCE
ROOFTOP ANALYSIS
• To get the most from solar
panels, you need to point them
in the direction that captures
the most sun.
• The following table shows the
angle calculation of my area.
ANGLE CALCULATION
• Now we will look into cost analysis of installing solar power system in my
house.
• The average daily usage of my household is about 3000 W to 3300 W.
• In the following slide I have the detailed cost analysis of 4 kW solar system
obtained from Zi Solar pvt Ltd .

• Solar irradiance (SI) is the power per unit area received
from the Sun in the form of electromagnetic radiation in
the wavelength range of the measuring instrument.
The solar irradiance integrated over time is called solar
irradiation, insolation, or solar exposure.
Irradiance
• Average solar irradiance is 5.4 kWh/m2/day
The following figures show the solar radiation intensity
on a horizontal surface (blue), on a vertical surface (red),
and on a surface perpendicular to the sunlight (black).
Latitudes and Longitudes of Sialkot are 70.8750 and 31
respectively. Optimum tilt angle calculated with respect to these
values comes about 27.88o from app

• In our area the average Annual irradiance is 1816 kWh/m2

LONGITUDE LATITUDE TILT AT
• In case of solar panel installation
angles are also very important for
optimal output. 72° 40' 31° 10' 58° 50'
• The table shows the angle for
solar panel installation for
optimal output.
• If I installed the solar panels on the roof of first floor, there will be main issue
of hindrance of sunrays reaching the solar panel due to our own second floor
and also neighboring houses.
• It will be good if it is installed on the rooftop of second floor. So there will be
no hindrance for sunrays.

• The purpose of this method is to join all the houses and sharing energy between them.
• This method is very effective if some house wants to spend more energy then it can normally
bear as it allows other houses to share their surplus energy.
• This method relies on other houses not using that much energy and is not very much
effective when all the houses are spending more energy.
