Sunrun gets a second contract to supply capacity from rooftop solar + batteries
A California Community Choice Aggregator has awarded Sunrun a contract to supply capacity from solar + storage on low-income housing. This follows on a similar deal in New England.
A pocket chart to maximize solar power deployment
Researchers have built a matrix outlining how solar power in various deployment models generates benefits greater than just clean electricity. This will help policy makers maximize energy decisions with limited resources.
Waste heat is not cool, say scientists
Engineers at the University of Utah have developed a tiny device which they say could increase the performance of PV panels and other electronic devices by converting energy lost as heat back into electricity.
The United States is headed for a battery breakthrough
A new report released by the U.S. Department of Energy projects that installed battery storage will reach 2.5 GW by 2023. Florida and New York are set to pave the way, as massive projects in each of those states will account for nearly half of the coming volume.
Toyota’s super-high efficiency solar car, Numbers for New York’s energy transition: pvMB 07/09/19
Happy Tuesday and welcome to this edition of the pvMB. On this fine, fine, Tuesday we’ll be looking at five states choosing solar, wind and storage over gas, the Glendale power plant replacement plan, POWERHOME Soalr’s CEO winning an award, and more!
‘Turbocharging’ silicon PV: MIT scientists scratch the surface of singlet exciton fission
Scientists at the Massachusetts Institute of Technology have developed a device they say could “turbocharge” a single-junction silicon PV cell, pushing the technology beyond its theoretical limit to efficiencies of 35% and higher.
When the battery is a building
AES announced the groundbreaking of its Alamito Energy Center, a 100 MW / 400 MWh battery for electric utility SoCalEdison, which is being constructed as a full on building – much like a data center.
Duke Energy hits 1 GW owned solar, 74.5 MW coming to Escambia: pvMB 7/3/19
Hello and welcome to your July 3rd pvMB! Today we’ll be tackling Bloom Energy going hydrogen, a jet fuel burning plant shutdown in Oakland, RPCS’ safe harbor strategy for ITC stepdown and more. Enjoy your holiday!
Battery scientists make a cracking observation
Scientists at the Georgia Institute of Technology in the U.S. used x-ray imaging to observe cracks forming in a solid state lithium battery, a discovery they say changes the understanding of performance of solid state batteries and which could lead to more durable systems.
PV interconnection requirements may change with new reliability guidance
Interconnection requirements for mid-sized and large inverter-based systems directly connected to the transmission grid may change based on new guidance issued in draft form by the North American Electric Reliability Corporation. The guidance does not apply to distributed PV.
