Solar PV Analysis of Nankana Sahib, Pakistan
Nankana Sahib, Punjab, Pakistan is a fairly good location for generating solar energy year-round. The amount of electricity that can be produced from solar panels varies throughout the year based on the seasons. In summer and spring, you can expect to generate around 6.36 and 6.52 kilowatt-hours (kWh) per day respectively for each kilowatt (kW) of installed solar power. This is quite high and makes these seasons ideal times to generate solar power at this location.
During autumn, the output drops slightly to about 4.75 kWh/day per kW of installed solar power but it's still a decent production level compared to many other places in the world during this season.
In winter, however, the production decreases more significantly to about 3.40 kWh/day per kW of installed solar power due to shorter daylight hours and lower sun position in sky which means less sunlight reaching your panels.
For best results with fixed panel installations at Nankana Sahib, Punjab, you should tilt your panels at an angle of 28 degrees facing southwards as it would maximise total year-round electricity generation from your photovoltaic (PV) system by ensuring they get maximum sunlight exposure throughout different times of day and different seasons.
As far as environmental or local factors are concerned that could hinder solar energy production at Nankana Sahib; dust storms or heavy air pollution could potentially reduce sunlight reaching your panels thus affecting their efficiency negatively if they occur frequently enough in this area which might need regular cleaning or maintenance activities like washing off dust/dirt buildup on panel surfaces for maintaining their performance levels.
Also while installing PV systems here; one should consider using durable materials resistant towards harsh weather conditions prevalent locally like high temperatures during summers along with proper cooling mechanisms incorporated within system designs so as not let them overheat adversely affecting their performance levels too much either due extreme heat exposures common here especially in summers etcetera besides other standard installation practices followed generally everywhere else.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 144 locations across Pakistan. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Nankana Sahib
Seasonal solar PV output for Latitude: 31.4495, Longitude: 73.6958 (Nankana Sahib, Pakistan), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
Ideally tilt fixed solar panels 28° South in Nankana Sahib, Pakistan
To maximize your solar PV system's energy output in Nankana Sahib, Pakistan (Lat/Long 31.4495, 73.6958) throughout the year, you should tilt your panels at an angle of 28° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Nankana Sahib, Pakistan
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Nankana Sahib, Pakistan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 28° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 15° South in Summer | 37° South in Autumn | 46° South in Winter | 24° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Nankana Sahib, Pakistan
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Nankana Sahib, Pakistan.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Nankana Sahib, Pakistan
Nankana Sahib is located in the Punjab province of Pakistan. The topography around Nankana Sahib is generally flat with some undulating areas. It is part of the fertile plains region known as the Indus River Valley, which has rich alluvial soil suitable for agriculture.
This type of terrain could potentially be well-suited for large-scale solar PV installations, particularly on land that isn't being used for crops or habitation. However, a detailed site assessment would need to be conducted to determine suitability, taking into account factors such as sunlight hours and intensity, land ownership and use restrictions, proximity to power grid connections and potential environmental impacts.
Areas nearby with similar topography include Sheikhupura to the east and Faisalabad to the west. These locations may also be suitable for large-scale solar PV projects given their relatively flat terrain and abundant sunlight.
However, it's important to note that while physical geography plays a role in determining where solar farms can be built, other factors like local climate conditions (especially cloud cover), infrastructure availability (for connecting the farm to the grid), local laws regarding land use and renewable energy projects also play significant roles in determining whether an area is suited for largescale solar PV or not.
Pakistan solar PV Stats as a country
Pakistan ranks 42nd in the world for cumulative solar PV capacity, with 1,083 total MW's of solar PV installed. Each year Pakistan is generating 6 Watts from solar PV per capita (Pakistan ranks 78th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Pakistan?
Yes, there are incentives for businesses wanting to install solar energy in Pakistan. The government of Pakistan has implemented a number of policies and initiatives to promote the use of renewable energy sources such as solar power. These include tax exemptions, subsidies, and other financial incentives for businesses that install solar systems. Additionally, the government has also set up a Renewable Energy Development Fund (REDF) which provides grants and loans to support renewable energy projects.
