US scientists claim clear-sky irradiance model provides better results for module testing

Researchers at the American Institute of Physics have used the clear-sky irradiance model developed by the National Renewable Energy Laboratory to measure the degradation rates of solar panels at a testing field in Germany over five years. The scientists say the model, when combined with real-world data, offers an efficient tool to evaluate the aging of PV technology.

A little Green Brilliance in a Virginian vineyard

The Indian installer supplied panels for a commercial client in the U.S. who had been inspired by a trip to Rajasthan with his wife in 2008.

“Our LFP battery technology is ideal for the Indian market”: SimpliPhi Power CEO

California-based SimpliPhi Power, which designs and manufactures lithium ferro phosphate (LFP) energy storage systems, has brought off-grid power to everything from the giant moon on Conan O’Brien’s talk show set to U.S. troops in Afghanistan and Iraq, to rooftops for Whole Foods and Airbnb. As the company prepares to enter into India, CEO and President Catherine Von Burg tells pv magazine why their LFP technology is best suited for India and their plans for the country.

Distributed storage market to grow nearly twentyfold by 2028

Market intelligence company Navigant Research has developed a country forecast of the global market. Incentives and pricing will be the main driver of installations, though the market will continue to be concentrated in certain key regions, including India, for now.

Lithium batteries – 12 lakh tons ready for recycling by 2030

The recycling market will experience a tenfold expansion between last year and 2030, driven by EV battery usage and portable electronics. Retrieving valuable metals and minerals is becoming a high priority and several dozen companies are already in position for the first big wave of end-of-life batteries.

Perovkiste solar cells need proteins

A U.S. research team has used protein bacteriorhodopsin to improve the efficiency of what it called ‘bioperovskite’ solar cells. The scientists used Förster Resonance Energy Transfer to predict the strength of long-range excitonic transport between the perovskite and protein layers.

A new battery mix to prevent dendrites

Scientists at the United States Pacific Northwest National Laboratory have discovered a root cause of dendrite formation, which can cause battery failure and even fires in lithium-ion technology. With this new knowledge, the group is now working on electrolyte recipes that eliminate dendrite growth entirely.

Global bill for replacement inverters and other solar maintenance could hit $9.4bn by 2024

This year will see strong growth for the global PV market, to 114 GW, and that pattern will continue in the years ahead, according to analyst Wood Mackenzie. A report has highlighted soaring inverter replacement costs for PV project owners as a side-effect of the solar success story.
