Global solar energy market size is likely to exceed USD 140 billion by 2023.

Cumulatively, more than 178 GW of power was installed in 2015 and is estimated to reach more than 600 GW over the forecast period, including both photovoltaic and concentrated thermal power. U.S. solar energy market size is expected to witness approximately 40 GW cumulative capacity by the end of 2016.

Rising population coupled with increasing non conventional energy prices are likely to drive market growth in Asia Pacific. China solar energy market size was dominant and accounted for more than 10.8 GW installations, followed by Japan with 9.7 GW installations in 2015.

UK contributed more than 2.4 GW to the Europe power installation market in 2015, followed by Germany and France. Middle East and Africa is expected to grow at as significant rate; increase in electricity prices and government subsidies are likely to be the key growth factors in the region.

This energy can be segmented into photovoltaic and concentrated thermal. Photovoltaic (PV) market size was estimated around 40 GW in 2015. Solar energy market trends include an estimated shift towards off-grid installations in some countries, where a large percentage of the population does not have an access to a national grid. Concentrated solar thermal market size is estimated to reach more than 25 GW installations during the forecast period.

Rising environmental concerns such as greenhouse gas emission accompanied by increasing energy consumption is leading industries towards more sustainable and cost effective energy resources. These factors are likely to positively drive the solar energy market growth.

Adoption is increasing due to natural resource depletion and increasing environmental consciousness. It is a reasonable fossil fuels substitute as well as an inexhaustible and affordable technology with huge long term benefits. More than 39% of energy is extracted with the help of coal which causes environmental pollution.
