Where is solar energy being used

Compared to the year before, the United States is one rank higher, having jumped past Germany. Additionally, India surpassed Italy, and France moved past Australia. Which countries have grown the most in the past decade for solar PV capacity?

Surprisingly, just 12 years prior in , China only had MW of solar PV installed, meaning the total capacity of installed solar in the country has grown by over 1, Solar panels can generate electricity just about anywhere on Earth, but some areas receive more sunlight than others, and as such, have a higher solar energy potential.

Solar Energy Solar radiation is light — also known as electromagnetic radiation — that is emitted by the sun. Solar Radiation Basics. Solar Energy Glossary. Photovoltaics Basics. Concentrating Solar-Thermal Power Basics. Systems Integration Basics. Soft Costs Basics. Going Solar Basics. Molten salt flowing through the receiver is heated to run a generator. Other solar technologies are passive. For example, big windows placed on the sunny side of a building allow sunlight to heat-absorbent materials on the floor and walls.

These surfaces then release the heat at night to keep the building warm. Similarly, absorbent plates on a roof can heat liquid in tubes that supply a house with hot water. Solar energy is lauded as an inexhaustible fuel source that is pollution- and often noise-free. The technology is also versatile. For example, solar cells generate energy for far-out places like satellites in Earth orbit and cabins deep in the Rocky Mountains as easily as they can power downtown buildings and futuristic cars.

Solar energy doesn't work at night without a storage device such as a battery, and cloudy weather can make the technology unreliable during the day. Solar technologies are also very expensive and require a lot of land area to collect the sun's energy at rates useful to lots of people.

Despite the drawbacks, solar energy use has surged at about 20 percent a year over the past 15 years, thanks to rapidly falling prices and gains in efficiency. Japan, Germany, and the United States are major markets for solar cells. With tax incentives, and efficient coordination with energy companies , solar electricity can often pay for itself in five to ten years. All rights reserved.
