Global Solar Energy Market Size Likely to Surpass at a CAGR of 16.5% By 2035

The market size of global solar energy will be estimated at USD 308 billion in 2025 and is expected to grow to between USD 359 billion in 2026 and about USD 1418 billion by 2035, with a current CAGR (compound annual growth rate) of 16.5% during the period of 2026 to 2035.

Solar Energy Market Revenue and Trends

Solar energy is the radiation in the sun that is directly used by several technologies, including photovoltaic cells, solar thermal collectors, and solar concentration power, which is used to produce electricity or heat. Because the energy supplied from the sun is plentiful, nearly unlimited, and would hardly have an impact on the environment, it can be seen as the world‘s most sustainable energy source. Solar energy systems allow the utilization of the sun’s radiant energy that can be utilized for electric generation, heat generation, or even to drive various industrial processes.

What are the Factors That Have a Significant Contribution to the Growth of the Solar Energy Market?

The rapid growth of utility-scale solar projects is another significant factor driving solar energy development. Utility-scale solar projects are large power stations developed by utilities or independent power producers for selling electricity to the grid. The utility-scale solar projects have recently been developed significantly, mainly because they can generate electricity at a lower cost per kilowatt-hour owing to the economies of scale and trade-off with fossil-fuel power plants. Electricity demand is growing fast; long-term power purchase agreements (PPAs) and government renewable energy targets are also factors encouraging investors to optimize large solar farm investments.

Different from general solar farms, many nations are investigating the giant solar parks and desert-based solar projects through which enormous amounts of renewable power could be produced efficiently and cost-effectively. Besides, with the application of solar tracking systems, bifacial PV modules, and high-efficiency PV cells, these utility-scale solar plants would go even further.

For instance, in March 2026, ACME Solar has entered into PPA agreements with SJVN for the 450 MW/1800 MWh IEC Firm and Dispatchable Renewable Energy (FDRE) projects. It is a foray toward a more reliable renewable power future for India by integrating renewable generation with storage. The project will facilitate cheaper deployment of reliable power, deliver grid stability and create a foundation for the faster adoption of large-scale clean energy into the country.

Also, increased electrification and electrical demand are key factors in driving the solar energy market. With expanding economies and advancements in digital technologies, the whole world is experiencing its increased electricity consumption across various industry sectors like transportation, manufacturing, data centers, residential infrastructure, etc. The widespread implementation of electric vehicles (EVs), smart cities, and electrification of industrial processes are further surging the requirement for clean, reliable, and sustainable electricity sources.

Since 2000, the world has observed a post-industrial revolution surge in the energy prices, which means a significant increase in consumer awareness towards alternate energy sources, making solar energy a preferred alternative for the world‘s increasing power demand. To counter these increased demands for power, governments and utilities are making massive investments into centralized solar power plants and distributed solar networks, thereby boosting the solar energy market.
