Solar Radiation Levels In Afghanistan: A Critical Analysis

Afghanistan has a high solar radiation norm of 700W/m^2, which makes it an ideal location for solar energy generation. The country enjoys long sunny days with high irradiation, ranging from 4.5 to 7 kWh/m^2/day. In June, when the sun shines at a latitude of 23.5° above the earth, the amount of radiant energy in the southernmost areas of Afghanistan is equal to 43.70 MJ/m^2.

The country has a landform class of high alpine close-spaced mountains and basin zones with extreme dryness and low rainfall, and high air turbidity. The combination of lower latitude and high-plateau terrain results in excellent solar assets.

The use of solar energy in Afghanistan is steadily increasing, with the country having the potential to produce over 222,000 MW of electricity by using solar panels.

Solar energy is an integral part of living things on Earth

Solar energy is essential for photosynthesis, which is a process by which plants convert sunlight into nutrients. These plants are then consumed by herbivores, who are in turn consumed by carnivores and omnivores. This process forms the foundation of the food web.

Solar energy also plays a crucial role in agriculture, which is the practice of cultivating land, producing crops, and raising livestock. Techniques such as crop rotation and drying food using sun and wind have increased harvests and prevented crops from spoiling. This has allowed for denser populations and structured societies.

Additionally, solar energy can be used for cooking and sterilizing medical equipment. It can also be used to heat water and make it potable. Furthermore, solar power, or the conversion of sunlight into electricity, has become an increasingly popular renewable energy source.

In Afghanistan, solar energy has the potential to produce over 200,000 MW of electricity. The country receives high levels of solar radiation, making it an ideal location for harnessing solar power. Various projects and initiatives are currently underway to utilize this abundant resource.

Solar power in Afghanistan has increased from 5.1 GW to 227 GW between 2005 and 2015

Afghanistan enjoys long sunny days with high irradiation, ranging from 4.5 to 7 kWh/m²/day. The country has a suitable radiation norm of 700W/m2 and a production capacity of 135,487 MW of electricity. The use of solar power is becoming widespread in Afghanistan, with solar parks and street lights in all major cities and towns. In rural areas, many villagers are also buying solar panels.

The country has seen a significant increase in solar power usage between 2005 and 2015, rising from 5.1 GW to 227 GW. This growth is attributed to the increasing adoption of photovoltaic (PV) panels, which convert sunlight directly into DC electricity. Afghanistan has the potential to further harness its abundant solar resources, with estimates indicating that the country has over 220 GW of solar energy potential.

The Bamiyan 1 MWp Solar Mini-Grid, one of the world's largest solar mini-grids, was installed in central Afghanistan in 2013. This project, a collaboration between the Government of New Zealand and Sustainable Energy Services International (SESI), provides primary power supply to the community during daylight hours through solar arrays connected to a distribution network.

Additionally, the largest solar thermal system (20m3/day) has been installed in Kabul University's women's dormitory, funded by the World Bank. This system utilizes Solar Thermal technologies, which convert solar energy into usable heat. With declining costs for solar thermal technologies and increasing policy support, Afghanistan can further tap into its solar energy potential to meet its energy needs.

The highest amount of solar energy is available at noon on summer days

Afghanistan has adequate areas and a suitable radiation norm (700 W/m^2) and a production capacity of 13548700 MW of electricity. The use of solar power is becoming widespread in Afghanistan, with solar parks established in several cities and solar-powered street lights seen in all Afghan cities and towns.

Afghanistan has adequate areas and suitable radiation norms (700W/m2) for solar power generation

Afghanistan has adequate areas and suitable radiation norms (700 W/m2) for solar power generation. The country's solar energy potential is estimated to be over 300,000 MW, with solar (222,849 MW), wind (66,726 MW), hydro (23,310 MW), and biomass (4,000 MW) as the main sources.

The country's high alpine close-spaced mountains and basin zones with extreme dryness and low rainfall, coupled with high air turbidity, make it an ideal location for solar power generation. The southern and western regions, in particular, have large solar assets due to their dry and highly reflective zones, such as deserts, plateaus, and upland pasture hillocks.

The annual average solar insolation in Afghanistan varies from 4 to 6.5 kWh/m2/day, with over 300 days of sunshine per year. The country's solar radiation levels, particularly DNI (Direct Normal Irradiance) levels, are high, making it a suitable location for Concentrating Solar Power (CSP) plants.

The amount of solar radiation in Afghanistan, in June, when the sun shines at a latitude of 23.5° above the earth, is approximately equal to 43.70 MJ/m2 in the southernmost areas. This figure drops to 19.85 MJ/m2 in December.

The country's solar resource is further enhanced by its geographical location, which makes the implementation of hydropower and hydro-energy easier. The large mountainous environment facilitates the siting of hydroelectric dams and other facets of hydro energy.

Afghanistan has the potential to produce over 222,0000 MW of electricity by using solar panels and about 4,0000 MW of power through biomass.

The use of solar power in Afghanistan is steadily increasing

Afghanistan has a high solar radiation level, and its use of solar power is steadily increasing. The country has a landlocked location and a population of fewer than 35 million, making it one of the lowest energy-consuming countries globally. It also has a small ecological footprint.

The country's renewable energy resource potential is estimated to be over 300,000 MW, with solar power contributing 222,849 MW. The annual average solar insolation varies from 4 to 6.5 kWh/m2/day, with over 300 days of sunshine per year.

The use of solar power in Afghanistan is becoming more common, especially in the country's south-west region, which produces almost 80% of the country's opium. Solar panels are being used to irrigate arid land, making it fertile for poppy cultivation. Before solar energy was introduced, farmers used diesel generators to pump water, but the expensive fuel limited the amount of water they could pump. Now, with solar power, a farmer can fill a large reservoir using two arrays of 18 solar panels powering two electric pumps.

The first Afghan farmer to use solar power did so in 2013, and since then, its use has grown exponentially, with sources counting 67,000 solar arrays just in the Helmand valley.

The country is set to increase its use of renewable energy, with a focus on solar power. In 2019, Afghanistan's Ministry of Energy and Water issued a tender for a 40 MW solar project in Herat province.

In addition to solar power, Afghanistan also has the potential to produce about 4,000 MW of power through biomass and 23,000 MW of hydroelectricity.

The country is also working on several wind power and solar energy projects, with a total capacity of 110 MW, expected to be added to the nation's power grid over the next 18 to 27 months.

Furthermore, Afghanistan has signed contracts with local and international companies to develop four renewable power projects with a total capacity of 4500-5000 MW by 2032.
