rooftop solar

The US Department of the Treasury has received about 8 GW of proposals for new solar and wind projects, while about 1.8 GW are available for 2023 tax credits.

Italian manufacturer Thermocold is offering new heat pumps with output ranging from 8 kW to 30 kW. They use propane as the refrigerant and reportedly have a seasonal coefficient of performance of up to 4.5.

In this Opinion and Analysis piece, Lumi Adisa, Director of Energy Market Analytics at NEOM and ex-Investment Director of Energy Markets at Octopus Investments Australia, presents a deep dive into the unprecedented impact of rooftop solar in the NEM. As rooftop solar continues to drive changes in the intraday demand and price trends, it is evident that customers will remain a significant part of the energy transition for years to come.

TotalEnergies had the biggest amount of utility-scale PV projects in its swag from July 2022 to June 2023, according to United States (US) research firm Mercom. The French energy company had 12 GW of solar projects operating, 3.8 GW under construction and 25.5 GW in the pipeline, according to Mercom’s hotly anticipated “Annual Global Report.”

E.ON has acquired German PV distributor Klarsolar, expanding its network of local businesses offering rooftop PV and residential storage systems. The financial terms of the transaction remain undisclosed.

The California Public Utilities Commission (CPUC) has prohibited the use of battery-tied solar exports to offset delivery charges, following its decision to slash the value of standalone solar exports in order to encourage the pairing of systems with battery storage.

Scientists in Spain have proposed to combine anaerobic digestion plants with photovoltaic-thermal panels and have found that this combination may achieve an LCOE of $0.045/kWh across several locations in Europe and North America.

Daikin has released a line of residential air-to-air heat pumps, using difluoromethane (R32) as the refrigerant, with outdoor unit dimensions of 662 mm x 442 mm x 1022 mm. The output ranges from 2.5 kW to 3.5 kW, and the seasonal coefficient of performance (SCOP) is between 4.85 and 5.17.

China’s National Energy Administration (NEA) says the nation’s renewables capacity includes 420 GW of hydropower, 404 GW of wind power, 536 GW of PV, and 44 GW of biomass.

Developed by researchers in China, the novel calculator uses current and voltage sensors, a Raspberry Pi, and an algorithm for fuzzy logic to determine variations in frequency and demand. The tool sends Email notifications with the tariff values to the PV system owners.
