Residential PV

Germany’s Bosch has developed an air-source heat pump that uses propane (R290) as the refrigerant. It can produce between 3.9 kW and 6.7 kW of heat, and domestic hot water to a temperature of up to 75 C. It says the heat pump can be paired with rooftop solar to maximize self-consumption.

Midsummer and researchers from the University of California, Los Angeles (UCLA), say that their new tandem PV cell is suitable for the company’s Duo production equipment, which makes 56 mm x 156 mm CIGS cells on a flexible stainless steel substrate.

Energy Systems Catapult has released interim data from air-source heat pump field monitoring in the United Kingdom between November 2020 and August 2022. Figures show that heat pumps are three times more efficient than gas boilers and that their median coefficient of performance (COP) on cold days is 2.44, compared to 2.80 year round.

After 800 Sungrow batteries were impacted by an outage, the Chinese manufacturer informed its local German partners about the solution to the problem. However, it remains unclear how quickly the affected battery management systems can be replaced.

Germany’s AEG is selling two versions of its new high-voltage residential batteries, with nominal capacities of 10 kWh and 15 kWh. They come with a 10-year warranty and reportedly have a lifecycle of more than 6,000 cycles.

More and more people want to invest in PV arrays and battery storage systems. However, there are a number of myths that could lead to disappointment among customers, according to one German consumer association.

Mitsubishi Electric has developed an air-source heat pump that uses propane (R290) as the refrigerant. It can produce between 5 kW and 8.5 kW of heat and domestic hot water to a temperature of up to 75 C.

Belgium-based Belinus says its new PV modules feature a nominal power rating of 420 W and a power conversion efficiency of 20.1%. It says plans are also in place to build a 500 MW solar panel factory at an unspecified Belgian site.

Zendure’s SolarFlow batteries have capacities of 960 Wh and can be stacked up to 3,849 Wh. The US manufacturer wants to begin selling the plug-and-play systems in April.

The record-breaking size and bustling halls of Enex Expo showed that the Polish PV market has no intention of slowing down. While last year’s switch from net metering to net billing is expected to continue to reverberate through the residential solar market, the commercial and industrial (C&I) and utility-scale PV market segments stand ready to pick up the slack.
