The first commercial use of solar cells was in the 1950s, when Bell Labs made them for application in space. At the beginning, the cost of solar energy was very large, and solar products were unavailable for households and wide use. However, things have changed since 1977 when the price of solar collectors has dropped nearly 100 times over. This was a great incentive for every solar company.
Solar technologies are well developed and the global competition in the renewable energy sector is very fierce. Some of the most famous solar companies are located in the U.S. and the countries of the Far East (China, Japan, Korea), but their large competitors are companies from the Western Europe (especially Germany). Here is a list of the most successful solar energy companies in the world.
