Residential PV

China’s National Energy Administration (NEA) and State Grid Corp. of China (SGCC) may ramp up PV curtailment to clear up space for new renewables projects that are struggling to obtain grid connections. Only up to 5% of PV output can currently be curtailed from solar plants, but the authorities are trying to decide whether to take a greater percentage of generation offline.

The Malaysian authorities have introduced a rebate scheme for residential PV, offering new net-metering users rebates of up to MYR 4,000 ($843.60). Applications are open until the end of the year, with allocation to be determined on a first-come, first-served basis.

Scientists have analyzed what factors affect the emergence of solar associations and cooperatives in Germany. Applying the organizational ecology theory, they found a collective solar initiative in a given district may likely lead to creation of similar experiences in the same district.

Poland added around 4.6 GW of new PV capacity in 2023, according to new data from research institute IEO.

Elevated metro stations may highly benefit from rooftop solar power generation combined with battery storage, new research from China suggests. The scientists proposed a system design that promises a payback time of 10.2 years without including the option of injecting surplus power into the grid.

The Japanese manufacturer said its new heat pump line features a modular approach to system design. The new products are available with capacities of 100 kW, 125 kW and 160 kW and can reportedly achieve a water output temperature of 60 C.

Official figures from Sweden’s energy association says more solar was added than estimates suggested during a record year for PV deployment in 2023, with the country’s cumulative capacity now standing at around 4 GW.

Solplanet, a China-based inverter manufacturer, says its new three-phase hybrid inverter series includes four versions with power ratings of 25 kW to 40 kW. They feature efficiencies of up to 98.4% and a maximum input voltage of 1,100 V.

Researchers at Germany’s Frauhofer ISE have analyzed the performance of a residential heat pump connected to a rooftop PV system relying on battery storage and have found that this combination significantly improves the performance of the heat pump while also increasing considerably the solar array’s self-consumption rate.

PV modules, inverters, charge controllers, batteries and cables intended for rooftop solar systems will benefit from exemptions from customs duties until 2025.
