Harunabad, Punjab, Pakistan, situated in the Northern Sub Tropics, presents a promising location for solar PV energy generation. This city experiences varying levels of solar potential throughout the year, with notable fluctuations across seasons.

Seasonal Solar Performance

Solar energy production in Harunabad peaks during the spring and summer months. In spring, the region sees an impressive output of 6.73 kWh per day for each kilowatt of installed solar capacity. Summer follows closely with 6.59 kWh/day. These seasons offer ideal conditions for maximizing solar energy generation.

Autumn experiences a moderate decline in solar potential, producing 4.89 kWh/day. Winter shows the lowest output at 3.81 kWh/day, which is still a respectable figure for solar energy production.

Optimal Panel Installation

For fixed panel installations in Harunabad, Punjab, the ideal tilt angle to maximize year-round solar production is 26 degrees facing South. This angle has been carefully calculated to account for the Earth's elliptical orbit and the location's specific latitude, ensuring optimal exposure to sunlight throughout the year.

Environmental Considerations

While Harunabad'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 the use of heat-resistant, high-quality solar panels are recommended. Additionally, installing panels with a slight tilt can help with natural dust removal during occasional rainfalls.

Overall, Harunabad's location proves to be highly suitable for solar PV energy generation, with strong potential throughout most of the year and manageable environmental challenges.

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 Harunabad

Seasonal solar PV output for Latitude: 29.7448, Longitude: 73.248 (Harunabad, 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 26° South in Harunabad, Pakistan

To maximize your solar PV system's energy output in Harunabad, Pakistan (Lat/Long 29.7448, 73.248) throughout the year, you should tilt your panels at an angle of 26° 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 Harunabad, 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 Harunabad, Pakistan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 26° 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	35° South in Autumn	44° 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 Harunabad, 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 Harunabad, 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 Harunabad, Pakistan

The topography around Harunabad, Pakistan, is characterized by flat, arid plains typical of the southern Punjab region. This area is part of the vast Indus River basin, with the landscape dominated by expansive agricultural fields and scattered settlements. The terrain is predominantly level, with minimal elevation changes across the region. The climate in this area is hot and dry, with scorching summers and mild winters. The flat terrain and lack of significant geographical features contribute to the region's susceptibility to extreme temperatures and occasional dust storms. Vegetation is sparse outside of cultivated areas, consisting mainly of drought-resistant shrubs and grasses.

Solar PV Potential

The topographical and climatic conditions around Harunabad make it an excellent candidate for large-scale solar photovoltaic (PV) installations. The flat terrain offers ample space for expansive solar farms without the need for extensive land preparation. The lack of natural obstacles, such as mountains or dense forests, ensures minimal shading and maximum exposure to sunlight throughout the day. Areas to the south and southwest of Harunabad would be particularly well-suited for large-scale solar PV projects. These regions experience even less rainfall and have fewer agricultural activities, reducing potential land-use conflicts. The vast, open spaces in this direction provide ideal conditions for solar panel arrays, with unobstructed access to sunlight and the possibility of easy grid connection to nearby population centers. Another promising location for solar PV development would be the areas to the east and southeast of Harunabad. These regions share similar flat topography and arid conditions, making them suitable for large-scale solar installations. The proximity to existing infrastructure and transportation networks in this direction could facilitate the construction and maintenance of solar farms. It's worth noting that while the entire region around Harunabad has potential for solar energy development, careful consideration must be given to factors such as land ownership, proximity to power transmission lines, and environmental impact assessments. Additionally, measures to protect solar panels from dust accumulation and occasional sandstorms would be necessary to ensure optimal performance and longevity of the installations.

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.
