Kot Addu, Punjab, Pakistan, situated in the Northern Sub Tropics, presents a favorable location for solar PV energy generation throughout the year. The site's geographical coordinates (30.4726° N, 70.9616° E) contribute to its potential for harnessing solar energy effectively.

Seasonal Solar Performance

Solar energy production in Kot Addu varies across seasons, with summer and spring offering the highest yields. During summer, the location can generate an impressive 6.65 kWh per day for each kW of installed solar capacity. Spring follows closely with 6.53 kWh/day. Autumn sees a moderate decrease to 5.03 kWh/day, while winter experiences the lowest output at 4.03 kWh/day per kW installed.

Optimal Times for Solar Generation

The most ideal periods for solar energy production in Kot Addu are during summer and spring. These seasons benefit from longer daylight hours and more direct sunlight, maximizing the potential of solar PV systems. However, it's worth noting that even during the less productive winter months, the region still maintains a respectable output, indicating year-round viability for solar energy generation.

Panel Tilt Angle for Maximum Efficiency

To optimize year-round solar production from a fixed panel installation in Kot Addu, Punjab, the ideal tilt angle is 27 degrees facing South. This angle has been calculated to balance the varying solar elevations throughout the year, ensuring the best possible energy capture across all seasons.

Environmental and Weather Considerations

While Kot Addu generally offers favorable conditions for solar energy production, there are some environmental factors to consider:

• Dust storms: The region can experience dust storms, which may temporarily reduce panel efficiency.
• High temperatures: Summer heat can slightly decrease solar panel efficiency.

To mitigate these issues, regular panel cleaning and maintenance should be implemented. Additionally, choosing high-quality, heat-resistant panels and ensuring proper ventilation during installation can help maintain efficiency in high temperatures. Despite these minor challenges, Kot Addu remains an excellent location for solar PV energy generation, with its year-round solar potential outweighing the occasional environmental obstacles.

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 Kot Addu

Seasonal solar PV output for Latitude: 30.4726, Longitude: 70.9616 (Kot Addu, 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 27° South in Kot Addu, Pakistan

To maximize your solar PV system's energy output in Kot Addu, Pakistan (Lat/Long 30.4726, 70.9616) throughout the year, you should tilt your panels at an angle of 27° 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 Kot Addu, 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 Kot Addu, Pakistan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 27° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
14° South in Summer	36° South in Autumn	45° South in Winter	23° 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 Kot Addu, 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 Kot Addu, Pakistan.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Kot Addu, Pakistan

The topography around Kot Addu, Pakistan, is characterized by a predominantly flat landscape typical of the Indus River plain. This region, located in the southern part of Punjab province, features expansive alluvial plains formed by the Indus River and its tributaries over millennia. The terrain is generally low-lying and uniform, with minimal elevation changes across vast stretches of land. The area surrounding Kot Addu is primarily agricultural, with numerous irrigation canals crisscrossing the landscape. These canals, fed by the nearby Taunsa Barrage on the Indus River, support extensive cultivation of crops such as cotton, wheat, and sugarcane. The flat terrain and the presence of these water sources have made the region a fertile agricultural hub.

Suitability for Large-Scale Solar PV

The topographical features of the Kot Addu area make it highly suitable for large-scale solar photovoltaic (PV) installations. The flat, open terrain provides ideal conditions for the deployment of solar panels over extensive areas without the need for significant land preparation or leveling. Several factors contribute to the region's suitability for solar PV projects: Firstly, the vast expanses of level ground allow for efficient layout and arrangement of solar panels, maximizing exposure to sunlight throughout the day. This flat landscape also simplifies construction and maintenance processes, reducing overall project costs. Secondly, the area experiences high levels of solar irradiation due to its geographical location and climate. The region receives ample sunlight throughout the year, with long, sunny days during the summer months, making it an excellent candidate for solar energy production. Thirdly, the presence of existing infrastructure, such as roads and power transmission lines, facilitates the development and integration of large-scale solar projects into the national grid. Areas to the south and southwest of Kot Addu, where agricultural activity is less intense, could be particularly well-suited for solar PV installations. These locations offer large, contiguous plots of land that could be repurposed for solar farms without significantly impacting food production. Additionally, the semi-arid climate of the region means there is less competition for land use compared to more densely populated or heavily forested areas. This factor further enhances the attractiveness of the Kot Addu vicinity for large-scale solar energy development. In conclusion, the flat topography, abundant sunshine, and available land make the areas around Kot Addu highly promising for the implementation of large-scale solar PV projects, potentially contributing significantly to Pakistan's renewable energy goals.
