Rooftop PV for pre-cooling of residential, commercial buildings
Australian researchers have developed a way to use rooftop PV to run air conditioners to pre-cool residential and commercial buildings. They have identified several factors that could help reduce a building’s energy costs.
PV with gravity storage, redox flow batteries in buildings
Indian researchers have developed a new hybrid system featuring a conventional rooftop PV system, a solar tree, two gravity power modules for building (GPMBs), and a vanadium redox flow battery (VRFB), with power exclusively provided by the two solar installations.
Italy hits 720 MW/1,361 MWh of distributed storage capacity
Italy added 303 MW/632 MWh of distributed energy storage capacity in the first half of 2022. The segment continues to grow in the country, with the regions of Lombardy and Veneto being the two largest contributors.
Supply chain difficulties translate into losses for SMA
SMA’s Home Solutions segment was particularly badly hit as the PV inverter manufacturer struggled to meet the demand due to the shortage of materials. The sales and results in the first half of 2022 were therefore significantly worse than in 2021. The company now wants to take “a series of measures to improve its long-term ability to deliver.”
Bosnian Serb Republic to back 250 MW of rooftop PV
The government of Bosnia and Herzegovina’s Serb Republic has adopted a net metering scheme to facilitate the deployment of 50,000 PV rooftop PV systems on residential and commercial buildings.
India installed 8.4 GW of solar in H1
India is expected to install 20 GW of new solar capacity in 2022, according to JMK Research.
Solar-plus-storage for LED lighting in commercial buildings
Indian researchers claim that commercial buildings with LED lighting could gain energy independence by installing standalone solar-plus-storage systems. They said a 914.4 kW PV system linked to lithium-ion batteries could be enough to power an entire building with an estimated annual demand of 190,830.7 kWh.
Impact of heat pumps on Ireland’s energy system
New research from Ireland shows that electrification could lead to more efficient utilization of renewable energy and the national transmission network.
Turkey simplify rules for self-consumption, solar irrigation
Turkey’s new provisions state that self-consumption projects and solar irrigation installations can be built without the need for construction permits.
US added 4.2 GW of solar in H1
The US Energy Information Administration expects 17.8 GW of solar capacity to be added to the grid by the end of this year.
