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).
A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical balance of system (BOS)–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.
Energy Conversion Devices (ECD) was an American photovoltaics manufacturer of thin-film solar cells made of amorphous silicon used in flexible laminates and in building-integrated photovoltaics. The company was also a manufacturer of rechargeable batteries and other renewable energy related products. ECD was headquartered in Rochester Hills, Michigan.
A virtual power plant (VPP) is a cloud-based distributed power plant that aggregates the capacities of heterogeneous distributed energy resources (DER) for the purposes of enhancing power generation, trading or selling power on the electricity market, and demand side options for load reduction.
Solar shingles, also called photovoltaic shingles, are solar panels designed to look like and function as conventional roofing materials, such as asphalt shingle or slate, while also producing electricity. Solar shingles are a type of solar energy solution known as building-integrated photovoltaics (BIPV).
BP Solar was a manufacturer and installer of photovoltaic solar cells headquartered in Madrid, Spain, with production facilities in Frederick, MD, India and the People's Republic of China. It was a subsidiary of BP.
A photovoltaic system, also called a 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.
SolarCity Corporation was a publicly traded company headquartered in Fremont, California that sold and installed solar energy generation systems as well as other related products and services to residential, commercial, and industrial customers. The company was founded on July 4, 2006, by Peter and Lyndon Rive, the cousins of SpaceX and Tesla CEO Elon Musk. Tesla acquired SolarCity in 2016, at a cost of approximately US$2.6 billion and reorganized its solar business into Tesla Energy.

SMA Solar Technology AG is a German solar energy equipment supplier founded in 1981 and headquartered in Niestetal, Northern Hesse, Germany. SMA is a producer and manufacturer of solar inverters for photovoltaics systems with grid connection, off-grid power supply and backup operations.
The energy sector in Hawaii has rapidly adopted solar power due to the high costs of electricity, and good solar resources, and has one of the highest per capita rates of solar power in the United States. Hawaii's imported energy costs, mostly for imported petroleum and coal, are three to four times higher than the mainland, so Hawaii has motivation to become one of the highest users of solar energy. Hawaii was the first state in the United States to reach grid parity for photovoltaics. Its tropical location provides abundant ambient energy.
Tigo Energy is an American private corporation, headquartered in Campbell, California, United States. It provides products, technologies, software, and services to installers, distributors, and original equipment manufacturers within the photovoltaic industry. It specializes in module-level power optimizers and smart module power electronics.
Enphase Energy, Inc. is an American energy technology company headquartered in Fremont, California, that develops and manufactures solar micro-inverters, battery energy storage, and EV charging stations primarily for residential customers. Enphase was established in 2006 and is the first company to successfully commercialize the solar micro-inverter, which converts the direct current (DC) power generated by a solar panel into grid-compatible alternating current (AC) for use or export. The company has shipped more than 48 million microinverters to 2.5 million solar systems in more than 140 countries.
