Solar panels blasted with sound to better understand microcracking
Researchers at NREL and EPRI focused heavy bass sounds on solar panels to simulate the effects of wind-caused deflection.
Plastic for solar panels?
Three companies are swapping out aluminum and glass in favor of plastic to save weight and add flexibility. We look at the pros and cons.
Microgrid-forming PV microinverter from Enphase
The 97%-efficient device is said to be the most powerful PV microinverter developed by the company to date and is capable of forming a microgrid during a power outage. The U.S. manufacturer expects to ship the first products in December.
Solar tile with 19.22% efficiency from Canada
The solar tile has a power output of 15 W and is recommended for flat concrete roof tiles. It can operate with a maximum system voltage of 600 V.
SolarEdge launches residential battery and inverter
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.
Highway-side solar could produce 36 TWh annually
A collaboration between universities, nonprofits, and a geospatial mapper led to development of a highway solar evaluation tool.
How varied energy storage can enable a low-cost renewable energy future
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.
DNV puts different module formats to the test
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.
Re-Source 2021: Q&A with Iron Mountain’s Chris Pennington
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.
Calculating the value of a US community solar program
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.
