A cooperation agreement was signed by the French corporations to launch the HyGreen Provence project, which is expected to produce annually 1300 GWh of solar electricity and 10,440 tons of green hydrogen by 2027.

A researcher has proposed a new approach to apply maximum power point tracking techniques to optimize electricity production in wind-solar power projects. The permanent magnetic synchronous generator hybrid model used in the study is based on a multi-input rectifier stage which is said to be able to eradicate current harmonics and eliminate the need for extra input filters.

Recent analysis from Wood Mackenzie predicts green hydrogen, produced primarily by solar electrolysis, will reach cost parity in Australia, Germany and Japan by 2030.

A source close to the company has told pv magazine although there are investment funds and utilities interested in buying the renewables business, an IPO for the entity has not been excluded.

The Italian oil and gas provider has signed a concession agreement with the government of the African oil country to build a 50 MW solar plant. The project is expected to be in the province of Namibe and will be part of the nation’s plan to deploy 600 MW of solar by 2022.

The latest study published by the International Renewable Energy Agency says the average solar electricity cost of $0.085/kWh produced by projects commissioned last year is set to fall to $0.048 next year, and $0.02-0.08 by 2030.

The successes and benefits of distributed micro-grids depend largely on intelligent controllers and the solutions on offer for such systems are diverse. In our market survey, we take a closer look at the products available from 24 manufacturers.

Italy’s main solar event, the Key Energy fair held in Rimini, demonstrated the continuing importance of rooftop PV for Italian renewables but also promised a gradual return for large scale solar. Industry insiders are hoping for at least one gigawatt of solar next year, on top of a projected 600 MW this year.

A U.S. research group has developed a metal-carbon-nanotube composite – MetZilla – which can be embedded in commercial, screen-printable silver pastes and is said to reduce the formation of hotspots in solar modules and to prolong panel lifespan. The composite metal contacts are also ‘self-healing’ as they are able to regain electrical continuity after cycles of complete electrical failure caused by extreme strain.

Spanish researchers have discovered a material said to offer radiative cooling and self-cleaning of devices which undergo critical heating during operation, such as PV panels. The thermal emitter enabled the scientists to lower the daytime temperature of silicon wafers by 14 degrees Celsius.
