California to cut solar net-metering payments by 75%
A vote is expected mid-December on a regulatory change that could severely dampen the value of new residential rooftop solar installations in California.
India installed 11.2 GW of solar in January-September period
India added 9.3 GW of utility-scale solar in the first nine months of 2022, as well as 1.3 GW of rooftop capacity and 600 MW of offgrid PV projects.
Luminescent solar concentrators for agrivoltaics, greenhouses
Moroccan researchers have proposed the use of luminescent solar concentrators for power generation in greenhouses and agrivoltaic projects. They say they are capable of producing electricity in low-light illumination and converting ultraviolet light to visible light that could be used for crops.
Italy hits 959 MW/1,826 MWh of distributed storage capacity
Italy added 303 MW/632 MWh of distributed energy storage capacity in the first nine months of 2022. The segment continues to grow in the country, led by the regions of Lombardy and Veneto.
China’s PV capacity hits 364.4 GW
IEA-PVPS says that China added around 58 GW of new PV capacity in the first 10 months of the year, bringing cumulative installations to 364.44 GW. It says up to 100 GW of new capacity could be deployed by the end of this year.
Mitsubishi unveils air source heat pump
Mitsubishi has released a cascaded air source heat pump that can produce between 7.8 kW and 640 kW of heat. It is reportedly able to generate hot water at a temperature of up to 70 C without boost heaters.
Kaco unveils string inverters for rooftop solar arrays
Kaco has launched a new line of blueplanet NX3 three-phase string inverters for applications ranging from small residential rooftop arrays to projects on commercial buildings. They have outputs between 3 kW and 33 kW, a maximum efficiency of 98.0%, and a maximum European efficiency of 97.6%.
Perovskites and microgrooves can revolutionize solar
Ambitious targets for solar energy generation present challenges to an industry keen to explore new avenues for solar production. Neil Spann, chief executive of UK thin film solar manufacturer Power Roll, describes a commercial solution to the problems of over reliance on silicon solar modules.
Philippines increases net-metering size limit for renewables to 1 MW
New provisions in the Philippines define interconnection standards, the certification of compliance requirements, and pricing methodologies, among other matters.
How variable is rooftop solar power?
A research group has developed a new methodology that shows PV systems located in the same area could have similar distributions of power ramps. Their three-step method could be used for the dimensioning of rooftop arrays and the scheduling of daily operations.
