The SunShot Initiative is a federal government program run by the US Department of Energy's Solar Energy Technologies Office. It bills itself as a national effort to support solar energy adoption in order to make solar energy affordable for all Americans. The initiative is a collaboration of private companies, universities, state and local governments, and nonprofits, as well as national laboratories. [1]
The United States Department of Energy (DOE) announced its sponsorship of the SunShot Initiative in 2011 and was established as a way to; increase utility of, photovoltaic goods and services in the United States by decreasing its original costs [2] in order to: (1)enable the competitiveness of the Solar Powered energy market, and supply chain comparatively to other energy sources, (2) increase the competitiveness of solar power energy market, (3) foster growth of research and development within the energy sector, specifically in solar energy alternatives, and (4) address the growing concern of climate change by triggering a more natural shift from fossil fuels to renewable energy sources in the long-run. [3] The initial goal set forth by the SunShot Initiative is to reduce carbon emissions to 20% of what they were at their highest recorded levels in 1990, by 2050. [4]
In order to achieve this goal, the DOE focused its efforts on using the increased feasibility of policy implementation processes in local governments to streamline the approach. By funding 25 major U.S. Cities through Solar America Program, the DOE sought to create readily available examples of the SunShot Initiative underlying mission at work. [3] This in turn, would facilitate the study of effectiveness in implementation processes in an urban setting, and provide idealized planning model based on already implemented policies, their effects, and potential challenges that could be encountered for reference, and create future implementation in other U.S. cities. [3] According to the cost/benefit analysis of cities participating in the Solar Cities America Program. These DOE efforts were geared towards incentivizing more U.S. cities to implement alternative energy source policies locally. [3] As well as increase the availability of viable policies that can be used in order to facilitate the development of a broader national or state policy. [3]
This initiative is meant to increase the availability of photovoltaic sources as viable alternatives to fossil fuels. As well as increase further analysis on the costs and benefits of solar power in the United States, through a comparative study on the mechanics of policy implementation in order to more effectively realize the overarching goal of the SunShot initiative. [3] The growth of the solar market in the United States, as a result of the SunShot initiative, has greatly increased the accessibility to solar powered technology and increased its general utility throughout the country, by reducing costs to consumers. The DOE has created these incentives in order to: (1)facilitate the increase of research and development, and (2) to promote renewable energy sources amid the globalized calls for a solutions to climate change/global warming.
The federal government invested $282 million in FY 2015 to fund the SunShot Initiative. [5] According to the SunShot Q4 2016/Q1 2017 Solar Industry Update report, The United States installed 14.8 GW of PV in 2016, an increase of 97% from 2015, representing approximately $30 billion in deployed capital, along with another $2.2 billion in U.S.- manufactured PV products. [6]
By 2016, the program achieved 90% of the progress towards the 2020 goal. [7] In September 2017, it was announced that it had already reached its 2020 goal, and was now refocusing on grid reliability issues. [8]
When the program was first launched in 2011 it set a series of goals and cost targets: [1]
In 2016, the SunShot Initiative announced new cost targets that it wanted to be achieved by the year 2030: [1]
According to the program, "These cost targets inform the decisions SunShot makes to spur the country’s solar market and drive deployment of solar energy." [1]
The SunShot Initiative is divided into five subprograms: [1]
All subprograms issue competitive awards to universities, national laboratories, nonprofit organizations, solar companies, and state and local governments to fund research and development projects that will aid in lowering the cost of electricity generated from solar technology. [9]

Distributed generation, also distributed energy, on-site generation (OSG), or district/decentralized energy, is electrical generation and storage performed by a variety of small, grid-connected or distribution system-connected devices referred to as distributed energy resources (DER).
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially utilized for electricity generation and as photosensors. The power system is controlled using power electronics.
Net metering is an electricity billing mechanism that allows consumers who generate some or all of their own electricity to use that electricity anytime, instead of when it is generated. This is particularly important with renewable energy sources like wind and solar, which are non-dispatchable. Monthly net metering allows consumers to use solar power generated during the day at night, or wind from a windy day later in the month. Annual net metering rolls over a net kilowatt-hour (kWh) credit to the following month, allowing solar power that was generated in July to be used in December, or wind power from March in August.
The National Renewable Energy Laboratory (NREL) in the US specializes in the research and development of renewable energy, energy efficiency, energy systems integration, and sustainable transportation. NREL is a federally funded research and development center sponsored by the Department of Energy and operated by the Alliance for Sustainable Energy, a joint venture between MRIGlobal and Battelle. Located in Golden, Colorado, NREL is home to the National Center for Photovoltaics, the National Bioenergy Center, and the National Wind Technology Center.
According to preliminary data from the US Energy Information Administration, renewable energy accounted for about 12.6% of total primary energy consumption and about 19.8% of the domestically produced electricity in the United States in 2020.
Financial incentives for photovoltaics are incentives offered to electricity consumers to install and operate solar-electric generating systems, also known as photovoltaics (PV).
A feed-in tariff is a policy mechanism designed to accelerate investment in renewable energy technologies by offering long-term contracts to renewable energy producers. This means promising renewable energy producers an above market price and providing price certainty and long-term contracts that help finance renewable energy investments. Typically, FITs award different prices to different sources of renewable energy in order to encourage development of one technology over another. For example, technologies such as wind power and solar PV are awarded a higher price per kWh than tidal power. FITs often include a "degression": a gradual decrease of the price or tariff in order to follow and encourage technological cost reductions.
Solar power is the conversion of renewable energy from sunlight into electricity, either directly using photovoltaics (PV), indirectly using concentrated solar power, or a combination. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine.
Solar power includes utility-scale power plants as well as local distributed generation, mostly from rooftop photovoltaics and increasingly from community solar arrays. From January through December 2021, utility-scale solar power generated 114.7 terawatt-hours (TWh), or 2.79% of all generated electrical energy in the United States. During the same time period total solar generation, including estimated small-scale photovoltaic generation, was 163.7 TWh.
A photovoltaic system, also PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and other electrical accessories to set up a working system. It may also use a solar tracking system to improve the system's overall performance and include an integrated battery.
Grid parity occurs when an alternative energy source can generate power at a levelized cost of electricity (LCOE) that is less than or equal to the price of power from the electricity grid. The term is most commonly used when discussing renewable energy sources, notably solar power and wind power. Grid parity depends upon whether you are calculating from the point of view of a utility or of a retail consumer.
Worldwide growth of photovoltaics has been close to exponential between 1992 and 2018. During this period of time, photovoltaics (PV), also known as solar PV, evolved from a niche market of small-scale applications to a mainstream electricity source.
Solar power in California includes utility-scale solar power plants as well as local distributed generation, mostly from rooftop photovoltaics. It has been growing rapidly because of high insolation, community support, declining solar costs, and a Renewable Portfolio Standard which requires that 33% of California's electricity come from renewable resources by 2020, and 60% by 2030. Much of this is expected to come from solar power via photovoltaic facilities or concentrated solar power facilities.
Different methods of electricity generation can incur a variety of different costs, which can be divided into three general categories: 1) wholesale costs, or all costs paid by utilities associated with acquiring and distributing electricity to consumers, 2) retail costs paid by consumers, and 3) external costs, or externalities, imposed on society.
Amonix, Inc. is a solar power system developer based in Seal Beach, California. The company manufactures concentrator photovoltaic (CPV) products designed for installation in sunny and dry climates. CPV products convert sunlight into electrical energy in the same way that conventional solar photovoltaic technology does, except that they use optics to focus the solar radiation before the light is absorbed by solar cells. According to a comparative study of energy production of solar technologies, CPV systems require no water for energy production and produce more energy per megawatt (MW) installed than traditional PV systems. Amonix has nearly 70 megawatts of CPV solar power systems deployed globally, including Southwestern U.S. and Spain. In May 2012, the Alamosa Solar Generating project, owned and operated by Cogentrix Energy, began commercial operation. This is the largest CPV power plant in the world and is expected to produce enough clean renewable energy per year to power more than 6,500 homes and will avoid the emissions of over 43,000 metric tons of carbon dioxide per year. The Alamosa Solar Generating Project is supported by a power purchase agreement (PPA), which is a long-term agreement to sell the power it will generate. Under the project's PPA, the Public Service Company of Colorado will buy the power generated by the solar facility for the next 20 years. In July 2012, Amonix set the world record for photovoltaic module efficiency at 33.5% under nominal operating conditions, verified by the National Renewable Energy Laboratory. In April 2013, Amonix broke the record set in July 2012, demonstrating photovoltaic module efficiency at 34.9% under normal concentrator standard operating conditions, also verified by the National Renewable Energy Laboratory. In August 2013, Amonix announced it had achieved a 35.9% photovoltaic module efficiency rating under concentrator standard test conditions (CSTC) as calculated by NREL. In June, 2014, the assets of Amonix were acquired by Arzon Solar, LLC for the purpose of continued development of CPV technology and products.
SVTC Technologies was a technology services company that provided development and commercialization services for semiconductor process-based technologies and products. SVTC operated from 2004 to October 2012.
A grid-connected photovoltaic system, or grid-connected PV system is an electricity generating solar PV power system that is connected to the utility grid. A grid-connected PV system consists of solar panels, one or several inverters, a power conditioning unit and grid connection equipment. They range from small residential and commercial rooftop systems to large utility-scale solar power stations. When conditions are right, the grid-connected PV system supplies the excess power, beyond consumption by the connected load, to the utility grid.
A photovoltaic power station, also known as a solar park, solar farm, or solar power plant, is a large-scale grid-connected photovoltaic power system designed for the supply of merchant power. They are differentiated from most building-mounted and other decentralised solar power because they supply power at the utility level, rather than to a local user or users. The generic expression utility-scale solar is sometimes used to describe this type of project.
Clean Power Finance, headquartered in San Francisco, California, is a financial services and software company for the residential solar industry.
Solar power in Pennsylvania currently provides less than 1% of the state's electricity, but there are many policies in place to regulate and incentivize its use. Pennsylvania mandates the use of solar power through a renewable portfolio standard, which requires a percentage of electricity from each providers to come from solar, and net metering, which compensates small-scale solar generation through net metering. By 2021, Pennsylvania was required to have 0.5% of its electricity from solar. Their following goal is 10% by 2030. Solar power could theoretically provide over 30% of the state's electricity, but growth in solar generation has slowed due to a reduction in solar grants and the low price of solar energy credits. Efforts have also seen blowback from citizens, most notably from Mount Joy Township. Although, Pennsylvania has ruled solar as a legal use, meaning local governments can only restrict size and placement, but can't disband the projects.
