Portable, grid-connected solar carport
The “Gismo Power” solar carport is entirely mobile, can be connected to the grid, and can be folded for storage.
Solar 101: Obvious and not-so-obvious US solar incentives
Here are three tools to help you navigate the sometimes-complex array of US state incentives for your rooftop solar project.
Perovskite stability, and the effects of defects
An international team of scientists fabricated perovskite solar cells which retained almost all of their initial 21% efficiency after 1,000 hours under continuous operation at their maximum power point. The researchers credit this performance to their discovery of an additive that served to ‘block’ ions that cause device degradation, and also hope their work will contribute to an improved understanding of the relationship between efficiency and stability in perovskite PV.
Greenyellow secures €21m financing for 30 MW solar park in Burkina Faso
The Nagréongo power station is located about 30km northeast of Ouagadougou and scheduled for commissioning at the end of 2021.
Giant electric boiler energized by wind and solar in the Netherlands
Swedish energy company Vattenfall is planning to build a 150 MW electric boiler near Amsterdam under the Netherlands’ SDE+ program for large scale renewables. The facility is planned to operate when a lot of electricity from wind and sun is available and to supply hot water to households in the city and its surrounding areas.
Engie switches on 60 MW of solar in Senegal
Engie energized two facilities with capacities of 35 MW and 25 MW, respectively, in the central part of Senegal. The two plants will sell power to the local grid under a 25-year PPA at a price of XOF25/kWh ($0.046).
Albania’s first floating PV plant is now operational
The 500 kW floating array was built with floating membranes supplied by Norwegian specialist Ocean Sun. The project is expected to continue its second implementation phase during the second half of 2021, when three more 500 kW floating units will be installed.
Canada Infrastructure Bank to invest in 250 MW/1,000 MWh storage project
The massive Oneida Energy Storage project in Ontario will store surplus energy during off-peak periods and provide grid-balancing services to reduce renewables curtailment.
Registrations of interest open for Australia’s 8 GW renewable energy zone
Australia’s largest renewable energy zone is one step closer to fruition with the New South Wales Government calling for registrations of interest from developers of solar PV, wind and energy storage projects.
Nano-micro-scale cooler for solar modules
The proposed technique is based on radiative cooling and consists of a glass coating made with a two-dimensional subwavelength nanostructured grating, which is imprinted in soda-lime glass and has enhanced mid-infrared emissivity, and a micro-structured grating. The temperature decrease provided by the nano-micro-grating coating was found to be approximately up to 5.8 degrees Celsius.
