Researchers from Finland’s Lappeenranta University of Technology have assessed the economic advantages of a fully interconnected global network. They found that an international grid could contribute to a global LCOE of €52.50/MWh. The higher complexity of such a system, however, would only be marginally compensated by additional economic benefits.

Scientists in the U.K. have developed a system which makes panels vibrate to provide cleaning. The academics have conceded, however, they are yet to calculate the ‘sweet spot’ of mechanical stress to be applied.

A U.S. research group is now developing new inverters to protect solar installations from cyberattacks. The researchers also aim to create new cybersecurity standards. Professor Alan Mantooth, the group’s research coordinator, said that inverters can be shut down if they are hacked, or contribute to grid instability and result in the overcharging of batteries, while potentially creating problems that we still don’t know how to address.

Although the Wiki-Solar website ranking only provides a snapshot of PV project engineering, procurement and construction contracts outside of China, it is nevertheless a useful indicator of the changing global solar market landscape. Of the top 11 companies, four are based in India, three in Germany, and two in the United States. But last year’s largest contractor, U.S.-based First Solar, might lose its leading position this year, as it has largely discontinued its EPC activities.

A French-Turkish research team has created an economic model to optimize scheduling for solar-powered EV charging units. The proposed model suggests that such projects might be more profitable today than at the end of the decade, depending on a wide range of variables.

France’s Sunbooster has developed a technology to cool down solar modules when their ambient temperature exceeds 25 degrees Celsius. The solution features a set of pipes that spread a thin film of water onto the glass surface of the panels in rooftop PV systems and ground-mounted plants. The cooling systems collect the water from rainwater tanks and then recycle, filter and store it again. The company claims the technology can facilitate an annual increase in power generation of between 8% and 12%.

The Asian Development Bank says developing countries in Asia and the Pacific should consider developing their own solar industry supply chains as the Covid-19 pandemic has exposed their over-reliance on China to carry through the energy transition.

A new, non-destructive technique has been proposed by researchers who say identifying early-stage discoloration in EVA encapsulants can help detect degradation in solar panels before power output is affected. The IIT Bombay group used an ultraviolet accelerated aging test during 34 days on three encapsulant samples.

US scientists claim to have discovered a membrane which could lead to cheaper large scale flow batteries. The material is an ion-selective, aqueous-compatible polymer with intrinsic microporosity known as AquaPIM and is said to have tunable thickness and high conductivity in aqueous electrolytes.

The International Water Management Institute is promoting the Solar Irrigation for Agricultural Resilience (SoLAR) initiative to expand the use of solar irrigation systems throughout Bangladesh, India, Nepal, and Pakistan. Proponents of solar irrigation pumps say that they can have a strong positive impact on groundwater.
