Sagri, Azad Jammu and Kashmir(POK), Pakistan, located at 33.5948°N, 72.0903°E, 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, making it an interesting case study for renewable energy production.

Seasonal Solar Output

The solar energy potential in Sagri fluctuates significantly across seasons. Summer stands out as the most productive period, with an impressive 7.15 kWh/day per kW of installed solar capacity. Spring follows closely behind, generating 6.60 kWh/day. Autumn sees a moderate decrease to 5.10 kWh/day, while winter experiences the lowest output at 3.79 kWh/day.

These figures indicate that Sagri is particularly well-suited for solar energy production during the warmer months, from spring through autumn. The extended daylight hours and clearer skies during this period contribute to the higher energy yield. However, even during the less productive winter months, the location still maintains a respectable output, ensuring year-round energy generation.

Optimal Panel Installation

To maximize the total year-round production from solar PV in Sagri, Azad Jammu and Kashmir(POK), fixed panels should be tilted at an angle of 30 degrees facing South. This optimal angle has been calculated considering various factors, including daily solar elevation angles, Earth's elliptical orbit, and NASA's solar irradiance data.

Environmental and Weather Considerations

While Sagri presents favorable conditions for solar energy production, there are some environmental and weather factors that could potentially impact solar panel efficiency:

• Dust storms: The region may experience occasional dust storms, which can deposit a layer of fine particles on solar panels, reducing their efficiency.
• Monsoon season: Heavy rainfall during the monsoon months could temporarily decrease solar output due to cloud cover and reduced sunlight.

To mitigate these challenges, several preventative measures can be implemented during solar installation:

1. Regular cleaning: Establish a maintenance schedule to clean panels, especially after dust storms or prolonged dry periods.
2. Water-resistant equipment: Use high-quality, water-resistant solar panels and inverters to withstand heavy rainfall during monsoon season.
3. Tilt adjustment: Consider installing adjustable mounts to optimize panel angles seasonally, maximizing energy capture during both summer and winter months.

By addressing these factors and implementing appropriate measures, Sagri can harness its substantial solar potential effectively, making it a viable location for year-round solar energy production.

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 Sagri

Seasonal solar PV output for Latitude: 33.5948, Longitude: 72.0903 (Sagri, 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 30° South in Sagri, Pakistan

To maximize your solar PV system's energy output in Sagri, Pakistan (Lat/Long 33.5948, 72.0903) throughout the year, you should tilt your panels at an angle of 30° 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 Sagri, 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 Sagri, Pakistan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 30° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
17° South in Summer	39° South in Autumn	49° South in Winter	26° 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 Sagri, 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 Sagri, 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 Sagri, Pakistan

The topography around Sagri, Pakistan, located at latitude 33.5948 and longitude 72.0903, is characterized by a diverse landscape that includes both flat plains and hilly terrain. This area is situated in the northern part of Punjab province, near the border with Khyber Pakhtunkhwa. The immediate vicinity of Sagri features gently rolling hills and small plateaus, with elevations gradually increasing as one moves towards the north and west. To the south and east, the terrain becomes flatter, transitioning into the fertile plains of Punjab. The region is part of the Potohar Plateau, a geologically significant area known for its varied topography. Several seasonal streams and small rivers flow through the area, carving shallow valleys and creating natural drainage systems. These water bodies contribute to the undulating nature of the landscape, with some areas featuring steeper slopes near the watercourses.

Suitable Areas for Large-scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Sagri, the most suitable areas would be found in the flatter regions to the south and east. These areas offer several advantages for solar energy development: Firstly, the relatively level terrain in these directions provides ample space for the installation of large solar arrays without the need for extensive land modification. Flat surfaces are ideal for maximizing solar panel efficiency and simplifying the construction process. Secondly, these areas typically receive more consistent sunlight throughout the day due to the lack of significant natural obstructions like hills or mountains that could cast shadows on the panels. This unobstructed exposure to sunlight is crucial for optimal energy generation. Additionally, the proximity to existing infrastructure in the more developed plains region could facilitate easier grid connection and transportation of materials during the construction and maintenance phases of a solar project. However, it's important to note that site-specific assessments would be necessary to determine the exact suitability of any location for large-scale solar PV installations. Factors such as local climate conditions, land ownership, environmental considerations, and proximity to power transmission lines would all need to be carefully evaluated before embarking on such a project.
