At the end of 2021, the total capacity of the solar power plants throughout the world was estimated to be 940 GW. According to the forecasts of solar association SolarPower Europe, the total capacity could reach 2 TW by 2025. With the rapidly growing popularity of solar power plants, experts predict that the next breakthrough in this sector will be smart batteries. In the future, solar power plants will not be able to operate without them.

Metal roofing has become a driver for roof type selection in many cases because not only is a metal/solar roof system less expensive upfront than other roof system combinations, but it also leads to improvements in the lifetime return on investment of the system.

Investments in renewables are hitting new highs in China, as recurrent Covid-19 outbreaks and a crisis-stricken housing market threaten the world’s second-biggest economy, according to BloombergNEF.

The authorities in China’s Guangdong province have released a 2022-25 plan that foresees the retail price for hydrogen dropping to less than CNY 30/kg ($4.42/kg). Germany and Canada, meanwhile, are set to strengthen their collaboration on hydrogen, and Ford has revealed plans to team up with Southern California Gas for a hydrogen fuel cell electric truck that will be on the road by 2025.

Scientists in China demonstrated a process to “heal” defects in a perovskite film by using an ammonia treatment after the film is formed through a solvent process. Small solar cells made using these films achieved maximum efficiency of 23.21%, while a mini-module with a 14-square-centimeter active surface area reached 20.61%.

Almost half a billion people are served by the off-grid solar industry, and a growing number of these via Pay-as-you-go (PAYGo) asset financing. For many consumers, not only is the solar product their first access to modern energy but it may also be their first access to finance. The impact of this can be huge – the 60 Decibels Energy Benchmark reveals that 92% of consumers report an improvement in quality of life after purchasing their off-grid solar (OGS) product. On the other hand, consumers of OGS are exposed to product, service, and financial risk that companies must mitigate and balance with sustainable growth objectives. 

Enphase Energy’s ClipperCreek unit is set to deploy more EV charging stations in the United States, and Siemens and Mahle have agreed to work on the standardization of wireless EV charging. Mercedes-Benz has expanded its battery supply partnership with CATL, while Tesla has announced that its gigafactory in Shanghai has produced its 1 millionth electric vehicle.

In a study that began in 2016, US scientists purchased 834 PV modules, representing seven manufacturers and 13 module types, and installed them in various climate conditions to observe their performance over time. The results show that, while plenty of opportunities still exist to extend module lifetimes and reduce performance loss in the field, reductions in the manufacturing cost of PV have not come with an increase in their degradation rate.

Hype and hope for solid-state batteries (SSBs) continues to grow as industries from automotive to storage bet big on the technology. Leading battery manufacturers and a roll call of start-ups are jostling to get from lab to fab. The reality of SSBs is in question though. As Marija Maisch reports, the window of opportunity for the decades-old technology to make the next big step toward commercialization is now.
