Nowadays, global electricity generation is mainly referred to fossil fuels and nuclear powers. Renewable sources are the other sector of energy production around the world which is including hydropower, solar, wind and others. The trends of global electricity production and the share of renewable sources are shown in the chart below:

The main reason of the inverse correlation between these two indicators is dependent on availability of infrastructure. In order to increase electricity production in short time, countries usually use available resources such as oil, natural gas and coal because usage of renewable sources like solar energy requires some facilities specially upgrading technologies and investments.

On the other hand, global installed capacity for solar energy reached around 227 GWe (Gigawatt-electrical) in 2015 which were 1% of all electricity used. The share of renewable energy in electricity production (including hydropower) by regions being mentioned in the table below:

As it can be seen, in most regions, because of the advantages of using solar energy including reducing environmental pollution, possibility of providing electricity in unexpected events and the job creation, the share of solar energy in electricity generation has been growing in recent years. Interestingly, major solar installations have been in the areas with less solar resources like Europe and China. However, available potentials in regions with high solar resources like Africa and the Middle East have remained untapped. At the moment, China, Japan, Italy, United States and Germany with large solar capacity installations over the last decade are the leaders in this field.

Iran, with about 300 sunny days on average per year and average of 5 KWh (Kilowatt-hour) radiation per day, is considered as a main solar energy center in the Middle East. In this regard, one of the biggest contract between Iran and Britain, after JCPOA, has been finalized recently in the field of building a solar power plant. The mentioned plant with 600 MW (Megawatt) of solar capacity and 800 million Euros of investments will be sixth biggest solar power plant around the world. It should be noted that Tengger Desert Solar Park (1500MW – China), Datong Solar Power Top Runner Base (1000MW – China), Kurnool Ultra Mega Solar Park (900 MW – India), Longyangxia Dam Solar Park (850MW – China) and Kamuthi Solar Power Project (648MW – India) are the other biggest solar power plants in the world. The exact executive place of the foresaid project is not clear but it is expected to take about three years to set it up through 100 MW phases every six months. Quercus Company, expert of renewable energy projects around the world, has committed to perform establishment, development and management of the solar power plant contract in Iran with financing 80% of its cost.

To conclude, sunny days in Iran are 6 times more than in Europe while according to the Iran’s ministry of power, installed solar energy is only about 63 MW in this moment!

On the other hand, based on the chart below, government’s tendency to use solar energy has being grown over the last few years in Iran.

Therefore, due to the continues improvement in global solar energy efficiency which has been reached to 46% beside much potential in this sector in Iran, JCPOA is a good opportunity for foreign investments in order to take advantages of renewable energies’ development.
