Solar PV Analysis of Havelian, Pakistan
Havelian, Khyber Pakhtunkhwa, Pakistan is a fairly good location for year-round solar energy production. This is because the amount of electricity that can be generated from solar power changes with the seasons, but it remains relatively high throughout the year.
In simple terms, for every kilowatt (kW) of solar panels installed at this location, you can expect to generate about 7.30 kilowatt-hours (kWh) of electricity per day in summer, 5.05 kWh/day in autumn, 3.49 kWh/day in winter and 5.81 kWh/day in spring.
The highest output will be during summer days when the sun is at its peak and there are longer daylight hours. Autumn and spring also provide decent amounts of sunshine that can be converted into usable energy by your panels.
Winter will have the least output as there are fewer daylight hours and sunlight intensity is lower due to the tilt of Earth's axis during this season. However, even then you're still able to generate a reasonable amount of energy from your panels.
For fixed panel installations at this location to maximize total year-round production from solar PV systems, they should ideally be tilted towards south at an angle of around 30 degrees.
However certain environmental or local factors could potentially affect solar production here:
1) Dust & Pollution: Havelian being located near industrial areas may have higher levels dust or air pollution which could settle on panels reducing their efficiency.
Preventative Measure: Regular cleaning/maintenance schedule should be established to keep panels clean and working efficiently.
2) Weather Conditions: Hailstorms or heavy snowfall could damage panels or reduce their efficiency.
Preventive Measure: Use durable weather-resistant equipment designed for such conditions; consider protective covers if necessary.
3) Shading Issues: Nearby buildings/trees might shade parts of your system during certain times reducing overall productivity.
Preventative Measure: Careful site selection/panel placement ensuring minimal shading.
Overall, while there are potential challenges, with good planning and maintenance, Havelian can be an effective location for 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 Havelian
Seasonal solar PV output for Latitude: 34.0587, Longitude: 73.1653 (Havelian, 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 Havelian, Pakistan
To maximize your solar PV system's energy output in Havelian, Pakistan (Lat/Long 34.0587, 73.1653) 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 Havelian, 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 Havelian, 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 |
|---|---|---|---|
| 18° 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 Havelian, 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 Havelian, 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 Havelian, Pakistan
Havelian, Pakistan is located in the Khyber Pakhtunkhwa province and is surrounded by a mix of mountainous terrain and plains. The area has significant elevation changes due to its proximity to the Himalayan foothills. The region experiences a temperate climate with warm summers and cool winters.
For large-scale solar PV installations, flat or gently sloping areas are most suitable as they provide ease of installation. In this regard, the plain areas around Havelian would be more suitable for such projects. Also important is accessibility for maintenance, connection to the power grid, and minimal environmental impact.
However, it's crucial to conduct a detailed site-specific assessment before embarking on any large-scale solar project. This should include factors like local weather patterns (including cloud cover), land ownership issues, potential impacts on local biodiversity among others.
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.
