Top Solar Energy Companies in the World 2019

solar energy companies

The global solar energy industry has witnessed a significant growth over the recent decades with several top solar energy companies leading the way. Due to the increasing concerns about environmental pollution and the climate change, the whole world is gradually switching over to the renewable energy revolution. As one of the most common and essential renewable energy sources, solar energy, also known as solar power, has been highly demanded and widely adopted around the globe. No matter whether it’s solar thermal, solar photovoltaic (PV), solar panel, or residential solar PV systems, the overall global solar energy industry is posing strong growth, while many world’s top solar energy companies are also benefited with increasing demand and rising sales.

What is Solar Energy?

Solar energy refers to the energy derived from the photons of the sunlight, which can be converted into solar thermal energy or electrical energy through solar panels. When harnessing photons of the sunlight, there are two main types of solar energy technologies: solar photovoltaic and solar thermal. The main difference is that solar photovoltaic technology directly converts sunlight into electricity, while solar thermal technology harnesses the heat of the sunlight. Solar energy is nowadays one of the most widely used renewable energy sources to provide environmental-friendly energy and power for both residential and industrial facilities.

Global Solar Energy Industry Overview

Solar photovoltaic power (PV) is one of the fastest growing segments of the global renewable power generation in 2017, as deployment boomed in China and prices continued to fall. The International Energy Agency (IEA) reports that the power generation from solar PV is estimated to have grown by over a third in 2017, up to 460TWh, representing almost 2% of total world electricity generation. IEA also forecasts that the total global solar photovoltaic power generation will reach 1,121TWh by 2022.

China is currently the world’s largest solar energy market in terms of solar energy production and solar power consumption. IEA suggests that China’s rapid increase of 53 GW capacity in 2017 was the major contributor for the global solar energy capacity growth. In early 2018, China surpassed its 2020 solar PV target outlined in its 13th Five-Year Plan. Since 2012, China’s share of global PV demand has grown from 10% to more than 55%. Many China’s major solar energy companies are nowadays the world’s leaders in this market.

When it comes to the global solar energy market size, several segments are expected to maintain a strong growth in the near future. According the recent report from Technavio, the global solar thermal market will register a CAGR close to 5% by 2022, while the global residential solar PV systems market size will grow by USD 266.18 billion during 2018-2022. The growth of the solar energy market is driven by rising concerns in environmental pollution and provision of government incentives & tax rebates to install solar panels. Increasing investments in renewable energy sector is also another factor driving the market growth.
