Efficiency of solar panels in different cities of Iran.
Iran is one of the sunniest countries in the world, with an average of more than 300 sunny days per year. This characteristic has made investing in solar panels across different regions of the country highly efficient. However, a common question among many enthusiasts is: how efficient are solar panels in different cities of Iran, and which regions have the best conditions?
Factors affecting the efficiency of solar panels
The efficiency of a solar power plant does not depend solely on the quality of the panels; the following factors also play a role:
- Amount of solar radiation (irradiation)
- Ambient temperature and seasonal variations
- Angle and orientation of panel installation
- Amount of dust and weather conditions
- Quality of maintenance and cleaning of panels
The best cities in Iran for building solar power plants
According to statistics from the Renewable Energy and Energy Efficiency Organization (SATBA), the highest levels of solar radiation have been recorded in the central and southern regions of Iran.
1. Yazd and Kerman
These provinces are known as the solar energy hubs of the country. The average solar radiation in Yazd and Kerman ranges from 5.5 to 6.5 kilowatt-hours per square meter per day, which provides the highest efficiency for solar panels.
2. Isfahan and Fars
In addition to having suitable solar radiation, these provinces also have good infrastructure for connection to the power grid. The efficiency of solar panels in these areas ranges from 5 to 6 kilowatt-hours per square meter per day.
3. South Khorasan and Sistan and Baluchestan
The eastern regions of the country also have ideal conditions for solar power plants. Dust is one of the challenges in these areas, but solar radiation is very high.
4. Tehran and Alboz
Although pollution levels and weather variations affect efficiency, installing small residential solar power plants in Tehran and Alborz is still economically viable. The average solar radiation in these areas is about 4.5 kilowatt-hours per square meter per day.
5. Northern Iran (Gilan and Mazandaran)
Due to high humidity and rainfall, the efficiency of solar power plants in these areas is lower. However, using residential solar systems combined with other energy sources can still be cost-effective.
Tips for Increasing Efficiency in Different Cities
- Adjusting the angle of panels according to the geographical location of each city
- Regular cleaning of panels to prevent dust accumulation
- Using high-efficiency panels in cloudy or humid areas
- Proper ventilation system design to prevent panels from overheating in hot regions
conclusion
The efficiency of solar panels in Iran varies depending on geographical location, but this clean energy can be utilized in almost all provinces. Regions such as Yazd, Kerman, Fars, and South Khorasan offer the highest efficiency, while even cities with moderate conditions, like Tehran, are considered suitable for investment in solar energy.
