Solar PV Analysis of Darya Khan, Pakistan
Darya Khan, Punjab, Pakistan, situated at latitude 31.789 and longitude 71.0971, offers a promising location for solar PV energy generation throughout the year. This Northern Sub-Tropical region experiences varying levels of solar potential across different seasons, with notable peaks and troughs in energy production.
Seasonal Solar Performance
The solar energy output in Darya Khan fluctuates significantly across seasons. Summer stands out as the most productive period, with an impressive 6.63 kWh per day for each kilowatt of installed solar capacity. Spring closely follows with 6.58 kWh/day, making these two seasons ideal for maximum solar energy generation.
Autumn sees a moderate decrease in production, yielding 4.95 kWh/day. Winter experiences the lowest output at 3.86 kWh/day, which is still a considerable amount of energy, albeit less than other seasons.
Optimal Panel Installation
For fixed panel installations in Darya Khan, Punjab, the ideal tilt angle to maximize year-round solar production is 28 degrees facing South. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's specific latitude.
Environmental Considerations
While Darya Khan's climate is generally favorable for solar energy production, there are some environmental factors to consider:
- Dust storms: The region may experience occasional dust storms, which can temporarily reduce panel efficiency.
- High temperatures: Summer heat can slightly decrease panel efficiency.
To mitigate these issues, regular panel cleaning and maintenance should be scheduled. Additionally, installing panels with a slight elevation from the ground can help reduce dust accumulation. Choosing high-quality, heat-resistant panels can also help maintain efficiency during hot summer months.
Overall, Darya Khan presents an excellent opportunity for solar PV energy generation, with particularly high potential during spring and summer months. With proper installation and maintenance, solar panels in this location can provide a significant and reliable source of renewable energy throughout the year.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

Solar output per kW of installed solar PV by season in Darya Khan
Seasonal solar PV output for Latitude: 31.789, Longitude: 71.0971 (Darya Khan, 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 Darya Khan, Pakistan
To maximize your solar PV system's energy output in Darya Khan, Pakistan (Lat/Long 31.789, 71.0971) 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 Darya Khan, 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 Darya Khan, 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 Darya Khan, 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 Darya Khan, 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 Darya Khan, Pakistan
The area around Darya Khan, Pakistan, is characterized by relatively flat terrain typical of the Punjab region. This part of Pakistan is situated in the Indus River plain, which is known for its expansive, low-lying landscape. The topography is generally uniform, with minimal elevation changes across the immediate vicinity.
The land surrounding Darya Khan is predominantly agricultural, featuring vast stretches of cultivated fields. These fields are interspersed with small settlements and villages. The terrain is mostly level, with occasional gentle undulations. There are no significant hills or mountains in the immediate area, making it an open and unobstructed landscape.
The Indus River flows to the west of Darya Khan, and its presence has shaped the local topography over millennia. The river's floodplain has created fertile alluvial soils, which contribute to the region's agricultural productivity. Some minor natural drainage channels and small streams may be present in the area, but they don't significantly alter the overall flat character of the landscape.
Regarding areas suitable for large-scale solar PV (photovoltaic) installations, the flat terrain around Darya Khan offers several advantages. The lack of significant geographical features that could cast shadows or obstruct sunlight makes much of the surrounding area potentially suitable for solar energy development. However, some key factors should be considered:
- Agricultural land: While the flat farmland could be ideal for solar panels, it's important to balance energy production with food security and local livelihoods.
- Areas near the Indus River: These might be less suitable due to potential flooding risks and the need to preserve riparian ecosystems.
- Uncultivated or marginal lands: These would be the most appropriate for large-scale solar PV installations, as they would have minimal impact on agriculture and local communities.
- Areas with good road access: This would facilitate construction and maintenance of solar facilities.
The regions to the east and southeast of Darya Khan, where there might be more uncultivated land away from the Indus River, could potentially be well-suited for solar PV development. However, a detailed on-site survey would be necessary to identify the most appropriate locations, taking into account local environmental, social, and infrastructure considerations.
