All-in-one device integrating a microinverter and optimizer

The so-called Optiverter is an all-in-one residential solution developed by startup Ubik Solutions and researchers from Estonia’s TalTech Power Electronics Research Group. The developers claim that the new solution can provide 30% more power than traditional microinverters under partially shaded conditions.

No such thing as ‘next-generation’ modules

According to one Dutch scientist, the development of PV technology in recent decades should be seen as an evolutionary process, rather than the constant emergence of new generations of equipment.

TOPCon technology hits 23.5% in mass production

Chinese manufacturer Jolywood claims it has reached 23.5% cell efficiency on the production lines for its n-type TOPCon technology. The achievement, which has not been verified by a third party, represents a 0.3% improvement to Jolywood’s reported mass production efficiency.

Solar pump moved by fuzzy logic

Researchers in the United Arab Emirates have proposed a PV-powered irrigation system that runs on a fuzzy logic-based algorithm, with a remote-control wireless monitoring system interface.

Solaria sues Canadian Solar for alleged patent infringement on PV cell ‘shingling’ tech

The U.S. solar panel manufacturer has filed a lawsuit against Canadian Solar in the Federal District Court for the Northern District of California.

Preventing PID at 1500 volts

Scientists in Germany have developed a “heavy duty” test to provide insight into the long term effects of potential induced degradation in PV modules. The tests go well beyond those established by IEC standards and seek to guide manufacturers and investors on the best choice of materials – encapsulants in particular – when it comes to long term PID resistance.

Chinese city bars all new solar this year

Yulin, in Shaanxi province has brought the curtain down on around 1 GW of PV projects which are under construction. It had previously been expected the city would add around 5 GW of new solar this year.

Chinese module manufacturer unveils bolt-on plan to raise capacity

A Solargiga subsidiary has handed over $2.5 million to almost double its stake in a 1.2 GW capacity module manufacturing business set up in June by investors which include the local government.

Trina announces its first shipment of 500 W modules

The Chinese manufacturer says the first products exited the factory 11 days after mass production started. The panels were launched by the company late last month.

Cooling down PV panels with water

France’s Sunbooster has developed a technology to cool down solar modules when their ambient temperature exceeds 25 C. 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%.
