Is solar energy popular in the world today?Yes, it is.Solar energy is very popular all over the world.The countries that use photovoltaic energy the most are: Japan, Germany, the United States, China, Australia, the Netherlands, Italy, Switzerland, Canada, France, Austria, Norway, Sweden, Finland, and the United Kingdom.The three countries have the largest number of residential and industrial photovoltaic units in the world, as they have government incentives for the world's largest renewable energy system.In Japan and Germany, the grid is the most popular.In the United States, bundled unitsthe off-grid ones.Japan and Germany lead the way in installing panels per person.Germany has installed about 1,500 MW of photovoltaic units nationwide, equivalent to 1% of the country's total electricity generation.This figure is expected to reach 25% by 2050.China's solar production accounts for 30% of the world's total.At present, the capacity of the panel installed in China is about 50 MW.The government plans to increase these figures to 20 gigawatts by 2020 (renewable energy is expected to account for 15% of the country's total energy in the next decade ).Australia currently produces more than 100 MW of photovoltaic power (0 MW only ).1% of the country's total electricity production ).Australia is the perfect place for PV installation, so why is solar not popular here?This is because these systems are very expensive here.The country plans to build one of the largest solar power plants, which will produce 450 MW of electricity enough to power 45,000 households.Canada mainly uses solar energy for space heating and water heating.It has more than 15,000 homes and more than 300 industrial solar hot water systems.Canada mainly uses independent off-grid units.Israel has no oil and tensions with its neighbors.They are looking for independent renewable energy solutions.There is a lot of sunshine in this country, mainly using solar energy as water heaters.Solar energy is also widely used in developing countries.For example, the market for photovoltaic equipment in Kenya is very large, and customers use the entrance-Level the modules according to their needs.Simultaneous use of Indiagrid-tied and off-grid systems.India is also in solar cookers, water heaters, water pumps and off-grid sun-Lighting system.Most countries do not have a power grid, which makes solar energy very practical here.It provides more than 16,000 photovoltaic home systems for families in rural areas.The Asian country uses domestic PV systems, especially those that do not provide normal power.There are special programs in this country that subsidize the "solar home system.These systems feature panels mounted on the roof that can power several lights, TVs, radios, and mobile phones, and provide about 50 w of power in direct sunlight.Pakistan has an average of 10 hours of sunshine per day, which makes the use of solar energy popular here.This country already has some solar power plants, which is a perfect place for the development of photovoltaic technology.
