The authorities in Mali have revealed plans to build a 200 MW solar plant with backing from Russia. The government of Mali has announced the construction of a 200 MW solar plant on 314 hectares in the southwestern part of the country.
The Sanankoroba solar plant will be built by Russia's Novawind, which is the renewable energy division of nuclear group Rosatom. Rosatom will build the plant for around XOF 120 billion ($198.6 million), with construction expected to last a year.
In October 2023, Mali and Russia agreed to develop civil nuclear power, according to Voice of America (VOA). The construction of two additional 200 MW solar power plants near Bamako is set to begin on May 28 and June 1. The electricity sector in Mali heavily relies on imported fossil fuels for thermal production.
A May 2023 report by the United Nations Development Programme (UNDP) stated that in 2020, Mali had a production capacity of 1,024.92 MW, including 162 MW from self-producers – all thermal. Electricity production stood 2,577.44 GWh, comprising 69% thermal energy, 26.8% hydroelectricity, and 4.2% solar.
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.
AC is the type of electrical current used when you plug appliances into normal wall sockets. What's the difference between solar PV panels and solar thermal panels? Solar PV panels generate electricity, as described above, while solar thermal panels generate heat.
At the core of solar panels is the photovoltaic (PV) effect. When sunlight strikes the solar cells, it excites the electrons in the semiconductor material, causing them to flow through the material. This flow of electrons is what creates electricity. The more sunlight that hits the solar cells, the more electricity is generated.
People now use many different technologies for collecting and converting solar radiation into useful heat energy for a variety of purposes. We use solar thermal energy systems to heat: Solar photovoltaic (PV) devices, or solar cells, convert sunlight directly into electricity.
According to studies by the U.S. Department of Energy, the all-in cost of a home solar panel system is between $2.74 to $3.30 per watt. 1,2,12 This figure includes the solar panels, the installation, and other expenses. Using these numbers, an average-sized 8-kilowatt residential solar system would cost between $21,900 – $26,400.
The price of solar panels changes depending on where you live, but the average for installation is just under $29,000 or $2.75 per watt. On the high end, we talked to a solar customer in Hawaii who spent $100,000 going solar. Dion in Nevada said their 10-kW system cost about $20,000, which is about the national average price for a 7-kW system.
Commercial solar installations are a great way for companies to lower energy costs. Generally, installing solar panels on businesses costs a bit less per watt because the systems are larger, but the total costs will be higher. In 2025, the average cost for commercial solar panels is just about $2.00 per watt.
The size of your solar power system, measured in kilowatts (kW), is the most important factor affecting solar panel prices. Naturally, larger systems cost more than smaller ones, but they usually offer a lower cost per watt. Solar panels typically account for 12 - 18% of the total installation cost.
