Solar PV Analysis of Rabwah, Pakistan
Rabwah, Punjab, Pakistan is a decent location for generating solar energy year-round, though some seasons are better than others. During the summer and spring months, you can expect to generate around 6.5 kilowatt-hours (kWh) of electricity per day for each kilowatt (kW) of solar panels installed. This means that if you have a 1 kW solar panel system, it could produce about 6.5 kWh of electricity daily during these times.
In autumn and winter, the output drops slightly with an average production of approximately 4.75 kWh/day in Autumn and even lower at around 3.40 kWh/day in Winter per kW of installed solar panels.
To maximize your total yearly production from your solar panels at this location, they should ideally be tilted at an angle facing 28 degrees South.
However, there may be local factors which could affect the efficiency of your solar system such as frequent dust storms or heavy rainfall which might cover the panels with dust or water droplets reducing their ability to absorb sunlight effectively.
To counter these issues:
1. Regular cleaning: Keep the surface clean by regularly washing off any accumulated dust or debris.
2. Weather-resistant materials: Use weather-resistant materials when installing your system to protect it from harsh weather conditions.
3. Optimal placement: Place your installation where it will receive maximum sunlight exposure throughout the year while avoiding shadows from nearby structures or trees.
Overall though Rabwah's location in Northern Sub Tropics makes it relatively ideal for harnessing solar power due to its ample sunlight availability especially during Spring and Summer months but necessary precautions should still be taken into account considering potential environmental challenges that might hinder optimal performance occasionally.
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 Rabwah
Seasonal solar PV output for Latitude: 31.7702, Longitude: 73.7446 (Rabwah, 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 Rabwah, Pakistan
To maximize your solar PV system's energy output in Rabwah, Pakistan (Lat/Long 31.7702, 73.7446) 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 Rabwah, 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 Rabwah, 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 |
|---|---|---|---|
| 16° South in Summer | 37° South in Autumn | 47° South in Winter | 25° 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 Rabwah, 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 Rabwah, 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 Rabwah, Pakistan
Rabwah, also known as Chenab Nagar, is located in the Punjab province of Pakistan. The topography around Rabwah is relatively flat with some small hills. It lies on the bank of the Chenab River and has a semi-arid climate.
The areas most suited for large-scale solar PV installations would likely be open, flat lands that receive ample sunlight throughout the year. The regions to the south and east of Rabwah are relatively flat and could potentially be suitable for such installations.
However, it's important to note that suitability for solar PV doesn't solely depend on topography. Factors like local weather patterns (cloud cover etc.), land use restrictions, proximity to power transmission lines or grid infrastructure are also significant considerations. Therefore a comprehensive feasibility study including all these factors would need to be conducted before determining the best locations for large-scale solar PV in this area.
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.
