Solarpanels in pakistan

2. Each cell=0.5 volts.

3. Pakistan is building solar power plants in
Azad Kashmir, Punjab, Sindh and Balochistan.
The program is under development by the
International Renewable Energy AgencyChina,
and
Pakistani
private
sector
energy
companies.
On May 29, 2012 Pakistan has stepped ahead by
inaugurating the first ever solar power on-grid power
plant in Islamabad. The Project titled "Introduction of
Clean Energy by Solar Electricity Generation System"
is a special grant aid project of Japan International
Cooperation Agency (JICA). This project includes the
installation of 178.08 kW Photovoltaic(PV) Solar
Systems each at the premises of Planning
Commission and Pakistan Engineering Council,
Islamabad.

5. A photovoltaic system typically includes a panel
or an array of solar modules, an inverter, and
sometimes a battery and/or solar tracker and
interconnection wiring.

6. Solar panels are available in the 100 watt and
higher range. Solar panels come in many sizes, up
350+ watts.
------------------------------------------------------------------Smaller panels are easier to handle and usually
cheaper to shift, while larger panels might be
cheaper to wire up and install.
------------------------------------------------------------------Panels in the 100 watt to 140 watt range are the
most
popular
for
PV
solar
systems.
------------------------------------------------------------------Few solar panels over 140 watts are available in
12 volt versions. Most are intended for grid-tie
applications, with panel voltages between 22 and
75 volts. Not suitable for battery charging.

8. 100 W panel = 10,000 Ruppees/ Panel
100 Ah Baterry = 15,000 Ruppees
--------------------------------------------------------TOTAL
= 25,000 Rs
With a total of only five 100 Watt solar panels
this Solar Home runs a refrigerator, computer, 27
inch color tv, microwave, various lights, misc
devices, and even an Air Conditioner in the
summer which will cost One lac.
Though the initial cost is too high but no running
cost.

12. The efficiency of the solar panels used in
a photovoltaic system, (in combination with
latitude and climate), determines the annual
energy output of the system.
For example,
A solar panel with 20% efficiency and an area
of 1m² will produce 200 watts of power, but it
can produce more when the sun is high in the
sky and will produce less in cloudy conditions
and when the sun is low in the sky.
Mirror increase the efficiency
of solar panels by 75%

13. In Pakistan, we have an average 1200 to 2200 hours
of sunshine per year with solar radiation approx. 2000
kWh/m2. pr. Year to 2400 kWh/m2. per year.
