Solar PV Analysis of Qeshm, Iran
The location at Qeshm, Hormozgan, Iran is quite suitable for generating energy through solar PV throughout the year. The amount of electricity that can be generated varies with each season, but it remains relatively high. In summer and spring, the output is highest with 7.70kWh/day and 7.47kWh/day respectively per kW of installed solar. This means that these are the best times to generate solar power in this location.
In autumn and winter, the output decreases slightly to 5.85kWh/day and 4.82 kWh per day respectively per kW of installed solar, but it's still a decent amount of energy production considering these are less sunny periods of the year.
To get the most out of your solar panels in Qeshm all year round, you should tilt them at an angle of 24 degrees towards South which will maximize their exposure to sunlight throughout different seasons.
However, there might be some local factors that could potentially hinder optimal solar production in this area such as dust storms or other extreme weather conditions common in desert areas which can cover panels blocking sunlight or even damage them physically over time if not maintained properly.
Also, since Qeshm is an island surrounded by water bodies on all sides; salt spray from sea winds may also cause corrosion over time affecting panel efficiency if not cleaned regularly.
To mitigate against these potential issues:
1) Regular cleaning & maintenance schedule should be implemented to remove dust/salt deposits from panel surfaces ensuring maximum light absorption.
2) Panels could be installed with a protective cover or coating that would help protect against physical damage from sandstorms or corrosion due to salt exposure.
3) If possible consider installing tracking systems for your panels so they can move following sun's path across sky maximizing their sunlight exposure during day hence increasing overall energy production.
4) Lastly using high quality durable panels designed specifically for harsh environmental conditions would also help ensure longevity & optimal performance over time.
In summary, Qeshm is a great place for solar energy production but like any location it comes with its own unique set of challenges that need to be taken into consideration for optimal results.
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 29 locations across Iran. 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 Qeshm
Seasonal solar PV output for Latitude: 26.9493, Longitude: 56.2848 (Qeshm, Iran), 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 24° South in Qeshm, Iran
To maximize your solar PV system's energy output in Qeshm, Iran (Lat/Long 26.9493, 56.2848) throughout the year, you should tilt your panels at an angle of 24° 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 Qeshm, Iran
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 Qeshm, Iran. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 24° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 11° South in Summer | 32° South in Autumn | 42° South in Winter | 20° 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 Qeshm, Iran
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 Qeshm, Iran.
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 Qeshm, Iran
Qeshm is an island located in the Strait of Hormuz off the southern coast of Iran. The topography of Qeshm is generally flat with some hilly areas. The island has a desert climate, characterized by long, hot summers and short, mild winters.
The region's geographical features make it potentially suitable for large-scale solar photovoltaic (PV) installations. Flat areas are ideal for ground-mounted solar panels, while the high annual sunshine hours can provide abundant solar energy.
Areas that would be most suited to large-scale solar PV include:
1. Desert Areas: Large expanses of flat desert land on and around Qeshm Island could be ideal for setting up large-scale solar farms due to their high sun exposure and lack of shading obstacles.
2. Coastal Areas: While coastal areas can sometimes have issues with corrosion due to saltwater, they also often have less cloud cover and therefore more sunlight. With proper equipment protection measures in place, these could be potential sites for PV installations.
3. Unused Land Spaces: Any unused or barren lands in and around Qeshm could also serve as potential locations for setting up solar farms without disrupting any existing ecosystems or residential areas.
However, before any definitive conclusions can be drawn regarding suitable locations for installing a large-scale PV system in this area, detailed studies on local climatic conditions (like average annual sunlight hours), land availability & usage rights along with environmental impact assessments would need to be conducted.
Iran solar PV Stats as a country
Iran ranks 52nd in the world for cumulative solar PV capacity, with 456 total MW's of solar PV installed. This means that 0.40% of Iran's total energy as a country comes from solar PV (that's 40th in the world). Each year Iran is generating 5 Watts from solar PV per capita (Iran ranks 80th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Iran?
Yes, there are incentives for businesses wanting to install solar energy in Iran. The Iranian government has implemented a number of policies and programs to encourage the development of renewable energy sources, including solar energy. These include tax exemptions, subsidies, and other financial incentives such as low-interest loans. Additionally, the government has set up a Renewable Energy Organization (SUNA) which provides technical assistance and support for businesses interested in installing solar systems.
