Solar PV Analysis of Tando Allahyar, Pakistan
Tando Allahyar, Sindh, Pakistan is a fairly good location for generating solar energy year-round. The amount of electricity you can expect to produce from each kilowatt (kW) of installed solar panels varies by season. In the summer, you can expect about 6.61 kilowatt-hours (kWh) per day, in autumn it's around 5.46 kWh/day, in winter it drops slightly to 4.86 kWh/day and then rises significantly in spring to approximately 7.21 kWh/day.
In simpler terms, this means that your solar panels will be most productive during the spring months and least productive during the winter months due to changes in sunlight exposure throughout the year.
To get the most out of your solar panels at this location all year round, they should ideally be installed at an angle facing 23 degrees South - this allows them to capture as much sunlight as possible over different seasons.
However, there could be some local factors that may affect solar production at this site - these include environmental or weather conditions such as dust storms or heavy cloud cover which could block sunlight reaching your panels; additionally local buildings or vegetation might cast shadows on your installation further reducing its efficiency.
As preventative measures against these potential issues:
1) Regular cleaning and maintenance of the panels would help ensure they are free from dust and debris.
2) If possible choose a site for installation where there is minimal shadowing from nearby structures or trees especially during peak sun hours.
3) Consider using tracking systems that adjust panel orientation throughout the day following sun's path across sky maximizing exposure time; though these systems are more costly than fixed installations initially but could increase overall energy yield making them worth considering depending on specific circumstances.
Overall Tando Allahyar seems like a viable location for installing solar PV with few manageable challenges given proper planning and maintenance practices are followed.
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 Tando Allahyar
Seasonal solar PV output for Latitude: 25.4707, Longitude: 68.7166 (Tando Allahyar, 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 23° South in Tando Allahyar, Pakistan
To maximize your solar PV system's energy output in Tando Allahyar, Pakistan (Lat/Long 25.4707, 68.7166) throughout the year, you should tilt your panels at an angle of 23° 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 Tando Allahyar, 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 Tando Allahyar, Pakistan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 23° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 9° South in Summer | 31° South in Autumn | 40° South in Winter | 19° 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 Tando Allahyar, 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 Tando Allahyar, 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 Tando Allahyar, Pakistan
Tando Allahyar is located in the Sindh province of Pakistan, which is known for its flat plains. The region is primarily agricultural with fertile lands and irrigation channels. It has a hot desert climate with extremely hot summers and mild winters.
Regarding large-scale solar PV installations, they require vast expanses of relatively flat land that receive ample sunlight throughout the year. Given Tando Allahyar's geographical location, it receives abundant sunshine most of the year making it suitable for solar energy production.
However, considering the high agricultural productivity of this region, it would be important to ensure that large scale solar projects do not disrupt local farming activities or lead to loss of arable land. An ideal solution might involve setting up solar panels on non-arable lands or developing agro-photovoltaic systems where agriculture and electricity generation from solar power can coexist.
Nearby areas such as Mirpurkhas or Hyderabad could also be potential locations for large-scale PV installations due to similar climatic conditions.
It should also be noted that feasibility studies including technical aspects (like grid connectivity), socio-economic impacts (like job creation vs displacement) and environmental considerations (like water use) need to be conducted before deciding on specific sites for such projects.
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.
