The DC-coupled battery has 94.5% round-trip efficiency and the inverter offers up to 11.4 kW power and 10.3 kW backup power.

A collaboration between universities, nonprofits, and a geospatial mapper led to development of a highway solar evaluation tool.

Research from the U.S. National Renewable Energy Laboratory shows that high-renewables operation is possible, and less expensive, when a range of energy storage technologies are used.

Energy consultancy DNV was tasked by module manufacturing giant Longi Solar with comparing the balance of systems costs between modules utilizing 182mm and 210mm wafers, based on a 3.7 MW project in three different layouts. The results reveal a slim cost advantage for the smaller of the two, based on both fixed tilt and tracker systems.

US data management company Iron Mountain has a growing portfolio of onsite and PPA renewables, and it’s one of the first major corporate firms to track its renewables by the hour as part of an innovative PPA that may serve as a forerunner for widespread 24/7 matching.

U.S. researchers have teamed up to analyze the economic benefit of annually adding 30 5 MW of community solar installations to Michigan’s grid for six years. Their results may surprise.

Scientists in the United States developed a method to observe the structure and mechanics of a perovskite material during its synthesis and transition from liquid precursors to a solid thin film. The group says its work will provide new insight into manufacturing and the development of reliable large-scale processes for perovskite solar cell production.

The state of New York will sell more than $200 million in equipment as Tesla plans to ramp up and expand operations at a manufacturing facility in Buffalo.

A report from Australia’s Future Battery Industries Cooperative Research Centre which analysed the development of battery hubs in the U.S., Germany and Japan, has found that co-location and cooperation between industry and government were key to their success. For Australia to play the same game, it will have to leverage its wealth of resources, and clean up its act along the way.

Prices for power purchase agreements have been rising steadily since the end of last year. According to solar developers, interconnection delays, permitting challenges, and supply chain constraints are likely to keep them high.
