PV system sizing for 100% self-consumption
A group of researchers has proposed a new method for the sizing of PV systems that do not rely on an anti-dump system and operate without the possibility of injecting power into the grid. The novel approach requires an estimate of the annual hourly profile and the minimum power demanded, as well as the use of an irradiance meter and an electrical network analyzer.
Storing solar power through aluminum-rock composite
UK-based Caldera has developed a new heat storage technology that can reportedly convert on-site generated solar power into on-demand heat, thus replacing conventional gas boilers. The system uses a composite of recycled aluminum and volcanic rocks to store heat at up to 500 C and produce steam.
Preliminary decision announced on U.S. solar cell imports
The preliminary decision on countervailing duties on cells from companies in Vietnam, Cambodia, Malaysia and Thailand are lower than some expected for several major Chinese producers.
Sunrise brief: Why $0.25 per kWh electricity makes off-grid solar & batteries a smart investment
Also on the rise: Groups challenge TVA’s draft resource plan that commits to only 3 GW solar. U.S. Senator introduces community solar act. And more.
Why $0.25 per kWh electricity makes off-grid solar & batteries a smart investment
Once electricity prices hit $0.25/kWh, disconnecting from the grid with residential solar-plus-storage starts to become financially viable, with sunny places making strong financial arguments. With recent drops in battery prices, the case for leaving the grid has grown even stronger.
U.S. installs 3 GW / 10.5 GWh of energy storage in Q2
The United States continues to set quarterly records for energy storage installations across market segments, said a report from Wood Mackenzie.
U.S. Senator introduces community solar act
Senator Luján is working to direct more resources to expand community solar, which he believes will lower energy costs for consumers, support good paying jobs and help reduce carbon.
LG Chem develops material capable of suppressing thermal runaway in batteries
LG Chem has announced that its Platform Technology R&D team has developed a temperature-responsive Safety Reinforced Layer (SRL), a material which is described as capable of suppressing thermal runaway.
Former landfill to transform into community solar project
New Jersey 5.7 MW solar project acquired by Standard Solar and Trinasolar will power homes and municipal facilities.
New model for diffuse, shadow effects on vehicle-integrated photovoltaics
Researchers at the Polytechnic University of Madrid have validated a model to simulate solar resources for vehicle integrated PV in urban settings, taking into account reflections and shadows of buildings and objects.
