Powering homes exclusively with hydrogen, solar, batteries
Researchers in Spain has found that combining PV power generation with fuel cells and battery storage may help homes considerably reduce their levelized cost of energy. Their simulation reportedly demonstrated homes may also become completely self-sufficient.
Hotter times will drive rooftop solar value
An analysis suggests rooftop solar will increase in value by between 19% to 25% due to warming and changing weather patterns increasing onsite electricity demand.
NREL interactive chart of solar cell efficiency now including ‘hybrid tandems’
The new cell category includes perovskite/silicon, perovskite/CIGS, III-V/silicon and perovskite/organic tandem PV devices. It will list the absolute record efficiency for all-perovskite, two-terminal tandems regardless of the number of junctions.

50 states of grid modernization
North Carolina Clean Energy Technology Center’s recent report looks at how states are doing with legislative and regulatory action related to shoring up the power grid.
Climate change to drive value of rooftop solar
University of Michigan researchers have found that the value of rooftop solar will increase by between 5% and 15% by the mid-century across a range of U.S. cities under moderate climate change, and by up to 20% by the end of the century.
New model shows how to power homes exclusively with hydrogen, solar, batteries
Researchers in Spain has found that combining PV power generation with fuel cells and battery storage may help homes considerably reduce their levelized cost of energy. Their simulation reportedly demonstrated homes may also become completely self-sufficient.
Novel PV-driven desalination tech achieves lower levelized cost of water
Scientists led by the Massachusetts Institute of Technology (MIT) have designed a new PV-powered desalination system based on the time-variant electrodialysis reversal (EDR) technology. The proposed system reportedly achieves lower levelized cost of water than conventional solar-powered desalination techs.
South Korea plans 120 GW space solar project
Two Korean research institutes are designing the 2.2 km × 2.7 km Korean Space Solar Power Satellite project with the aim of providing approximately 1 TWh of electricity to the Earth per year. The proposed system should use 4,000 sub-solar arrays of 10 m × 270 m, made out of thin film roll-out, with a system power efficiency of 13.5%.
Improve transmission planning and interconnection cost allocation, says SEIA-affiliated group
Federal regulators should consider specific reforms to improve transmission planning, lower interconnection costs and provide cost certainty, says a group affiliated with the Solar Energy Industries Association.
