White Cliffs Solar Power Station was Australia's first solar power station. It is located at White Cliffs, New South Wales, which was chosen as it has the highest insolation in New South Wales, and in 1981 when the station was constructed had no grid connection.
Many countries and territories have installed significant solar power capacity into their electrical grids to supplement or provide an alternative to conventional energy sources. Solar power plants use one of two technologies:
Solar power is a major contributor to electricity supply in Australia. As of December 2023, Australia's over 3.69 million solar PV installations had a combined capacity of 34.2 GW photovoltaic (PV) solar power. In 2019, 59 solar PV projects with a combined capacity of 2,881 MW were either under construction, constructed or due to start construction having reached financial closure. Solar accounted for 12.4% of Australia's total electrical energy production in 2021.
Renewable energy in Australia is mainly based on biomass, solar, wind, and hydro generation. Over a third of electricity is generated from renewables, and is increasing, with a target to phase out coal power before 2040. Wind energy and rooftop solar have particularly grown since 2010. The growth has been stimulated by government energy policy in order to limit the rate of climate change in Australia that has been brought about by the use of fossil fuels. Pros and cons of various types of renewable energy are being investigated, and more recently there have been trials of green hydrogen and wave power.
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current. 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 in New Mexico in 2016 generated 2.8% of the state's total electricity consumption, despite a National Renewable Energy Laboratory (NREL) projection suggesting a potential contribution three orders of magnitude larger.
Solar power in Arizona has the potential to, according to then-Governor Janet Napolitano, make Arizona "the Persian Gulf of solar energy". In 2012, Arizona had 1,106 MW of photovoltaic (PV) solar power systems, and 6 MW of concentrated solar power (CSP), bringing the total to over 1,112 megawatts (MW) of solar power. As an example, the Solana Generating Station, a 280 MW parabolic trough solar plant, when commissioned in 2013, was the largest parabolic trough plant in the world and the first U.S. solar plant with molten salt thermal energy storage.
The Davidson County Solar Farm is a 17.2 megawatt solar power station located in the heart of North Carolina, near the community of Linwood. SunEdison built the array of photovoltaic panels, and Duke Energy buys all the output from the solar farm. The solar farm is located on North Carolina Highway 47, off New Jersey Church Road.
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 different from most building-mounted and other decentralized solar power because they supply power at the utility level, rather than to a local user or users. Utility-scale solar is sometimes used to describe this type of project.
Solar power in Florida has been increasing, as the cost of solar power systems using photovoltaics (PV) has decreased in recent years. Florida has low electricity costs compared with other states, which makes individual solar investment less attractive. Florida ranks ninth nationally in solar resource strength according to the National Renewable Energy Laboratory and tenth in solar generation by the Solar Energy Industries Association.
Solar power in Illinois has been increasing, as the cost of photovoltaics has decreased. As of the end of 2020, Illinois had 465 megawatts (MW) of installed photovoltaic and concentrated solar power capacity combined employing over 5,200 jobs. Illinois adopted a net metering rule which allows customers generating up to 40 kW to use net metering, with the kilowatt hour surplus rolled over each month, and lost at the end of either April or October, as selected by the customer. In 2011, the limit was raised to 2 MW, but is not net metering, as the term is commonly known, as it uses two meters for systems larger than 40 kW.
Mount Signal Solar, also known as Imperial Valley Solar Project, is a 794 MWp (614 MWAC) photovoltaic power station west of Calexico, California, United States, in the southern Imperial Valley, near the Mexican border. The facility is being developed and constructed by 8minutenergy Renewables in three phases, with two completed as of 2018. At full build-out, it will be one of the world's largest PV solar farms with a capacity of about 800 MWp (600 MWAC). The project has been supported by several environmental groups, as the power station was built on low productivity farmland.
The Springbok Solar Farm is a 443 MWp (350 MWAC) photovoltaic power station in the northwestern Mojave Desert, near California City in eastern Kern County, California. The facility was developed and constructed by 8minutenergy Renewables in three phases. It is among the country's largest PV solar farms with a capacity of about 440 MWp (350 MWAC).
Renewable energy in South Africa is energy generated in South Africa from renewable resources, those that naturally replenish themselves—such as sunlight, wind, tides, waves, rain, biomass, and geothermal heat. Renewable energy focuses on four core areas: electricity generation, air and water heating/cooling, transportation, and rural energy services. The energy sector in South Africa is an important component of global energy regimes due to the country's innovation and advances in renewable energy. South Africa's greenhouse gas (GHG) emissions is ranked as moderate and its per capita emission rate is higher than the global average. Energy demand within the country is expected to rise steadily and double by 2025.
Darling Downs Solar Farm is a 110MW photovoltaic solar power station in Queensland, Australia developed by APA Group 45 km west of Dalby in the Darling Downs region next to the Darling Downs Power Station. All of the power it produces will be sold to Origin Energy until 2030. It connects to the national electricity grid through Powerlink's Braemar substation. It has approximately 430,000 solar panels on an area of approximately 250 hectares.
Daydream Solar Farm is a photovoltaic power station developed by Edify Energy in Springlands, Whitsunday Region, Queensland, Australia. It uses a single-axis tracking system to follow the sun across the sky. It generates up to 180MW DC and 150MW AC.
Kidston Solar Project is a photovoltaic solar power station built on top of the former Kidston Gold Mine utilising the tailings storage facility in northern Queensland, Australia. The project consists of two solar farms, KS1 and KS2. The Kidston Solar Project is the first of four projects that comprise the Kidston Clean Energy Hub also occupying this area. A 250 megawatt (MW) hydro-pumped storage power generation project and a 150 MW wind farm make up the third and forth components. The site is located close to an existing substation and transmission line.
The Western Downs Green Power Hub is a large solar farm near Chinchilla in Queensland, Australia. The photovoltaic solar power station uses one million solar panels to generate 400 megawatts of power. It utilizes 72-cell bi-facial solar modules on a system that tracks the sun throughout the day. It is the largest solar farm in Australia.
