Residential PV

While it initially had a chilling effect on the Polish residential solar market, the transition from net metering to net billing has also resulted in positive changes, such as better sizing of rooftop PV systems and a higher rate of self-consumption, says Instytut Energetyki Odnawialnej (IEO), a Polish research body.

iDM has developed a modular air-source heat pump that uses propane (R290) as the refrigerant. It can produce between 2 kW and 24 kW of heat and domestic hot water up to a temperature of 70 C. A larger version can produce between 10 kW and 50 kW of heat.

The International Renewable Energy Agency (IRENA) told Berlin Energy Transition Dialogue participants this week that $5.4 trillion of annual investment is needed to support the global shift to renewables. Kenyan President William Ruto, meanwhile, called for a fair energy partnership between Europe and Africa.

The Czech Republic is pouring an additional CZK 55 billion ($2.5 billion) into its New Green Savings program, which includes rooftop PV rebates, among other energy-saving measures in the residential sector.

The Indian states of Rajasthan, Gujarat and Karnataka now account for more than 50% of the nation’s cumulative installed solar capacity.

Greece’s Ministry of Environment and Energy has revealed a new €200 million ($215.3 million) subsidy program for solar projects and small storage systems in the residential and agricultural segments. The scheme is backed by the country’s post-pandemic recovery plan.

The International Renewable Energy Agency (IRENA) explains how to optimally use its SolarCity Simulator, an open-access platform designed to help member countries to deploy PV systems at the municipal level.

Zhang Yingbin, Trina Solar’s head of global product strategy, speaks to pv magazine about the path to a supply chain dominated by n-type TOPCon products. He says Trina Solar will reach 30 GW of TOPCon solar module capacity by the end of 2023.

C2F has developed a building-integrated PV (BIPV) facade made of aluminum that purportedly limits the impact of hot and cold weather, while also improving solar module performance.

South Korea has cut its 2030 renewable energy target from 30.2% to just 21.6%, as it seeks to reduce support for solar and other clean energy sources, while preparing the ground for more nuclear power and liquefied natural gas. A lobby group is now challenging the plan in the Seoul Administrative Court.
