Hover Energy’s 36 kW rooftop-mounted microgrid combines wind, solar and energy storage
Hover’s first 36 kW installation survived the recent Hurricane Ian storm system that ravaged southwest Florida.
California set to release anti-rooftop solar net metering plan
Previous drafts of the plan slashed the value of rooftop solar blaming rich solar-owning Californians for a utility cost shift to less wealthy residents. A new study by Berkeley Labs showed that middle-income and working-class Californians were by far the largest buyers of rooftop residential solar.
BayWa r.e. optimizes business model for agrivoltaics
BayWa r.e. has begun optimizing its sheep count while experimenting with shepherd partnership business models.
Air-source heat pump for harsh, cold climates
Carrier will soon begin field tests for a prototype air-source heat pump for cold climates. It is designed to provide high-efficiency heating performance in harsh climates with temperatures equal or below negative 20.2 degrees Fahrenheit, while being grid-interactive. The heating tech specialist expects to commercialize the solution by 2024.
PV as energy infrastructure – technology renaissance or marketing hype?
The 2022 Inflation Reduction Act (IRA) has, in effect, launched PV and energy storage professionals into the Energy Infrastructure business. The question becomes, “What is PV and energy storage as Infrastructure and what does it mean to all energy stakeholders, not just the energy private sector?”
Duke Energy puts $4 billion price tag on renewable energy unit
By selling its renewable business, the southern utility plans to focus on its core operations. The sale could amount to the largest renewable transaction in the U.S.
Sunrise brief: Major utilities seek dismissal of California community microgrid proposal
Also on the rise: American Battery Factory and Anovion form alliance for supply of synthetic graphite. Underground heat exchanger to cool down solar panels . And more.
Underground heat exchanger to cool down solar panels
Spanish scientists have built a cooling system featuring heat exchangers on solar panels and U-shape heat exchangers installed in a borehole at a depth of 15 meters. The researchers claim that this reduces panel temperatures by up to 17%, while improving performance by about 11%.
Utility-scale solar construction costs halve 2013 averages, while wind and natural gas are relatively flat
Utility-scale solar projects used to cost nearly $4,000 per kW to build in 2013. By 2020, they fell to $1,655 per kW.
Utility-scale solar slowed in Q3 2022
Solar had its slowest quarter in two years in terms of deployment, hampered by global supply challenges that slowed growth, delayed projects, and drove up prices.
