- China is the world’s largest user of solar power, generating about 224 GWh of electricity from solar alone, with a predicted 370 kWh of solar added by 2024.
- Solar power is mostly driven by government incentives, and many countries are embracing a renewable energy transition to strengthen their economies in the post-COVID era.
- Solar installations are getting more affordable, and they are predicted to grow in both residential and commercial markets in the United States, with 1 solar installation every minute possible by 2024.
Who are the most likely buyers of solar panels?
Solar panels are being considered by about half of homeowners in the South Atlantic states (51 percent), up 20 percentage points from 2016. Homeowners in other Southern states (the East and West South Central region) are more interested in installing solar panels (45% in 2019 vs. 34% in 2016), albeit the difference is not statistically significant (11 percentage points). Only 3% of Southern homeowners claim they have solar panels on their roofs, which is the same percentage as in 2016.
The weather in the southern states is ideal for solar electricity. North Carolina, Georgia, and Florida are among the nation’s leaders in large-scale solar capacity, such as solar panel farms, but not in small-scale solar, such as residential solar. Solar advocates contend that no rules have been adopted in the region to encourage the construction and usage of rooftop solar panels. For example, solar residential rooftop panels cannot be installed and owned by a third party other than the principal utility in Florida and some other Southern states, which raises the cost of installation.
Homeowners in Western countries are more likely to report they have already installed solar panels. In the Pacific region, 14 percent of homeowners have done so, while in the Mountain region, 17 percent have done so.
California has the highest capability for electricity generation from small-scale solar power in the country. According to the EIA, California accounted for 43 percent of all small-scale solar electricity generation capacity in the United States as of September 2019. Beginning in 2020, solar panels are projected to be required on most new homes in California. Other Western states, such as Arizona and Hawaii, are also among the country’s leaders in small-scale solar power.
Solar panels are being considered by homeowners for a variety of reasons. The vast majority of households who have previously installed solar panels or are seriously considering doing so say they want to help the environment (87 percent ). Almost everyone (96 percent) wants to save money on their utility expenses. Solar panels can also boost the value of a home, according to a recent survey.
A lesser percentage of homeowners (67%) indicate that receiving a solar investment tax credit is one of the reasons they have installed or plan to install solar electricity at their home. Since 2005, a federal tax credit for solar projects has been in existence, and it will continue to be accessible to homeowners in some form until 2021.
What kind of industry makes use of solar panels?
Solar energy may create heat for a range of industrial uses, including water desalination, increased oil recovery, food processing, chemical synthesis, and mineral processing, to name a few. This can be accomplished using either concentrating solar-thermal power (CSP) technology or photovoltaic-powered resistive heaters or heat pumps. When solar-thermal energy is concentrated for industrial processes, mirrors are utilized to focus sunlight onto a receiver, which, when compared to electric heaters, may easily attain very high temperatures.
CSP is ideally suited for a wide range of commercial applications, from relatively low-temperature food-production operations to chemical processes that require very high temperatures, due to its ability to attain a wide range of temperatures. Learn more about CSP technologies and how they function.
Why is Solar for Industrial Processes Important?
According to the Energy Information Administration, the industrial sector consumed 35 percent of total end-use energy and 32 percent of total energy in the United States in 2019. Developing solar solutions for industrial processes contributes to the Solar Energy Technologies Office’s goal of creating a carbon-free energy sector by 2050. Learn more about SETO’s CSP objectives.
SETO Research in Solar for Industrial Processes
Many of the projects in this category are focused on solar thermal desalination, which has the ability to purify highly concentrated brines from seawater, underground aquifers, and industrial wastewaters for use in municipal, agricultural, and industrial water sources. SETO research is also assisting in the development of ultra-low-cost solar collectors and thermal energy storage technologies that are suitable for a variety of low-temperature industrial operations. SETO is sponsoring studies to build high-temperature thermal systems capable of transcending the temperature restrictions of conventional CSP systems for industrial operations that demand high temperatures. Solar for industrial processes is a focus of several of SETO’s funding programs:
- Solar Desalination Prize is an American-made competition aimed at speeding up the development of low-cost desalination devices that employ solar-thermal energy to produce clean water from salt water.
- New technologies that employ solar-thermal energy to help create freshwater from otherwise unsuitable waters are being investigated as part of the Solar Desalination financing initiative.
- Developing thermal storage systems capable of producing steam for industrial operations is a priority for the Solar Energy Technologies Office’s Fiscal Year 2019 grant program.
- The Solar Energy Technologies Office’s FY2019-21 Lab Call grant program is looking on solar hybrid techniques to generate power and/or heat for industrial manufacturing processes.
- The Solar Energy Technologies Office’s financing program for Fiscal Year 2018 includes improving components present in CSP subsystems, such as thermal transport systems.

Who and why uses solar energy?
In one hour, more energy from the sun falls on the earth than is utilized by everyone on the planet in a year. Sunlight is converted into useful energy for buildings using a variety of ways. Solar photovoltaics for electricity, passive solar design for space heating and cooling, and solar water heating are the most often used solar technologies for homes and businesses.
Solar technologies are used by businesses and industry to diversify their energy sources, enhance efficiency, and save money. Solar photovoltaic and concentrating solar power technologies are used by energy producers and utilities to create electricity on a large scale to power cities and small towns.

How well-known is solar energy?
Solar power contributed for 3% of total electricity output in the United States in 2020, according to our Electric Power Annual. Solar is expected to account for 4% of US energy output in 2021 and 5% in 2022, according to our Short-Term Energy Outlook. Solar generation will account for 14% of total US generation in 2035 and 20% in 2050, according to our Annual Energy Outlook 2021 (AEO2021) Reference case, which assumes no changes in present laws and regulations. In the electric power, residential, commercial, and industrial sectors, these data cover electricity generated from utility-scale (those with a producing capacity of 1 megawatt or more) and small-scale (those with a generating capacity of less than 1 megawatt) solar facilities.
Solar energy has been used by humans for generations, and solar-powered electricity was first produced in the United States in 1954. Solar energy can now be used to generate electricity in two ways: photovoltaics (PV) and solar thermal. Solar PV cells, such as those found on rooftop solar panels, convert sunlight directly into electricity. Solar thermal facilities use mirrors to focus sunlight at a central receptor, generating the high temperatures required for a steam-powered turbine to create electricity.
Much of the early rise in solar power net generation in the United States was driven by increases in small-scale solar, particularly in the business and residential sectors. Small-scale solar accounted for 68 percent of total solar electricity net generation in the United States in 2011. Utility-scale solar generating, on the other hand, expanded significantly in the United States during the last decade as average solar power plant building prices plummeted.
The electric power industry continues to produce the most solar generation, expanding from 68 percent in 2020 to 78 percent in 2050, according to our long-term predictions. The availability of a 10% Investment Tax Credit (ITC) for utility-scale generation after 2023 contributes to the growing share of utility-scale generation; however, the ITC for small-scale solar has expired.
The anticipated percentage of solar power in the AEO2021 is influenced by estimates about the installation and operating costs of other generating technologies, especially in the later years of the projection period, when solar trends are increasingly determined by economic considerations rather than policy. Solar generation achieves 25% of total generation by 2050 in a sensitivity case where natural gas costs are higher than in the Reference case (the Low Oil and Gas Supply case), compared to 20% in the Reference case. Solar generation accounts for 27 percent of total generation by 2050 in another sensitivity case (the Low Renewables Costs case), in which installed renewables costs are lower than in the Reference case.
What are the benefits of solar panels?
A photovoltaic system includes several components, one of which is a solar panel or solar module. They are made up of a panel made up of a succession of solar cells. They come in a variety of rectangular designs and are used to generate power in groups. Solar panels, also known as photovoltaic panels, absorb energy from the Sun in the form of sunlight and convert it to electricity that can be used to power homes or businesses. These panels can be used to complement a building’s electrical supply or to deliver power to remote areas.
Solar is used in large-scale industrial or utility applications in addition to residential and commercial applications. Thousands, if not millions, of solar panels are placed into a gigantic solar array, or solar farm, in this case, which supplies electricity to enormous urban populations.
Who buys solar panels and why?
Most people associate people who purchase solar power systems with being wealthy and well-educated city inhabitants, or perhaps young, liberal environmentalists.
However, the demographics of solar purchasers are shifting. According to a new Australian study, families with low and medium incomes in the suburbs are buying the most solar electricity right now, at least in that country.
Because of technological advancements, the cost of solar power has gradually decreased in recent years. Government financial incentives are also helping to drive use of the technology.
In Australia, the government has used incentives such as feed-in tariffs to stimulate solar adoption, according to a report published in the journal Renewable and Sustainable Energy Reviews by Jeff Sommerfeld of Queensland University of Technology in Brisbane. Between 2008 and 2013, the number of Australians who installed solar photovoltaic (PV) equipment increased from 8,000 to over one million.
Those who purchased solar electricity in the past were defined by their high income, education, and property ownership. Sommerfeld and his colleagues desired a more detailed, in-depth grasp of the numerous forces at play.
Over the course of five years, they conducted a rigorous statistical analysis of more than 2 million people in southeast Queensland. Income, mortgage repayments, rent, family size, ownership, education status, and the number of bedrooms were all taken into account.
They discovered that the profile of a typical solar customer now differs significantly from that of a decade ago. The vast majority of those who install solar do so in the suburbs, where typical salaries are often lower.
One thing hasn’t changed: solar users still have the option of owning a home. Solar homes were most likely to have three or more bedrooms and be occupied by a family of two or more, according to the researchers. Furthermore, those over the age of 55 are large solar buyers, most likely because they want to keep their electricity expenses down.
Who are the people who buy solar energy?
There are five different types of solar customers.
- The Investor as a Consumer The investment consumer seeks the highest possible financial return on her investment.
- The Environmentalist is a person who is concerned about the environment.
- The Technologist is a person who studies technology.
- The Solar Enthusiast is a person who is passionate about the sun.
How many people have solar panels in their homes?
In the United States, more than 2 million houses installed solar panel systems in 2019. Despite the COVID 19 epidemic in 2020, the Solar Energy Industries Association (SEIA) estimates that solar panel installations have surged by 43% during 2019.
