Jinko claims two more efficiency records for bifacial panels

The Chinese manufacturer has achieved conversion efficiencies of 21.82% and 22.49% for its p-type PERC and n-type HOT bifacial panels, respectively. The results were confirmed by Germany’s TÜV Rheinland.

Solar park taking shape along 40 km of road in the Netherlands

The Dutch water management agency plans to install solar panels along both sides of the A37 highway in Drenthe province, as well as on the median strip, to cover 300 hectares in total. The project is part of a plan to build projects on state land, as the domestic PV industry continues to search for alternative surfaces on which to deploy solar.

New lithium-sulfur battery unveiled by Aussie scientists

Scientists at Monash University claim to have developed the world’s most efficient lithium-sulfur battery. They say the new device could enable an electric vehicle to drive more than 1,000km on a single charge.

‘You can’t go wrong with solar’

2.5 MW of solar is being deployed at three project sites in Papua New Guinea, with commercial operations likely to begin within nine months. The installations will provide power in the island province of New Ireland at lower prices, while also improving access to electricity.

A solar-powered irrigation pump with pay-as-you-go option

Comet-ME has developed a solar-powered submersible borehole piston pump for off-grid communities and smallholders to use for irrigation and domestic purposes. The device, compatible with PV systems from 300-900 W in size, can pump water from 45m with as little as 50 W of continuous solar power.

Vietnam to stop licensing large-scale solar projects

In a newly published policy document, Hanoi has urged regional governments and the country’s state-run utility, EVN, to suspend authorizations for new solar parks until further notice. Around 8.93 GW of utility-scale solar capacity is already approved for development in Vietnam, according to the Ministry of Industry and Trade.

Charging an electric vehicle in 10 minutes

Scientists from Penn State University have developed a self-heating battery for electric vehicles which is said charge in only 10 minutes at 60 degrees Celsius.

Hydrogen production as an antidote to grid constraints in northern Netherlands

Dutch transmission system operator Enexis, gas provider Gasunie and oil company NAM are considering diverting excess solar capacity in Drenthe province into hydrogen production. The companies are assessing which wind and solar projects may have been excluded from the grid.

Walking on sunshine

Chinese scientists have developed a PV floor tile they say is suitable for pavements and cycling tracks. The devices were tested on a ‘green deck’ in Hong Kong. The developers say the tiles have demonstrated satisfactory solar energy conversion, anti-slip performance, heat-resistance and strength.

100% renewables means 95% less water consumption for conventional power generation

According to a new study by Finland’s LUT University, solar PV consumes between 2% and 15% of the water that coal and nuclear power plants use to produce just 1 MWh of output; for wind, this percentage ranges from 0.1% to 14%. Under the researchers’ best policy scenario, water consumption could be reduced by 75.1% by 2030, compared to 2015 levels.
