The 20 Best Solar Companies in the World


Solar power is increasingly becoming a popular energy source in many homes and businesses. Solar energy development started in the late 19th century but stalled in the early 20th century because of the increased availability of coal and petroleum. The 1973 and 1979 oil and energy crisis caused governments worldwide to look for alternative energy sources, which led to a reorganization of their energy policies. People started to embrace solar energy again, and the 21st century has seen an incredible boom in the use of solar power by many establishments.

Solar technology has drastically improved in the past few decades, and solar battery systems have made it a more efficient energy source. The rise of solar energy can be attributed to the ongoing climate change, and people now recognize the benefits of renewable energy to the environment. The International Energy Agency has said that developing clean and affordable solar energy can provide countries with cost-effective energy solutions. Despite the high cost of buying and installing a solar system, more and more companies are manufacturing solar systems. We can assume the increase in supply will lower the prices in the future. The increasing demand for solar systems has seen the rise of solar manufacturers worldwide.
