An international research group has analyzed a vertical bifacial agrivoltaics system in a drought-stricken part of Chile. They say that the solar array can improve water efficiency for crop irrigation, while the vertical system configuration optimizes PV power generation throughout the day, minimizing curtailment.

The new systems include a battery, an inverter and a control system. The U.S. manufacturer claims its storage systems have a lifespan of over 10,000 cycles and a depth of discharge of 80%.

Johnson Controls-Hitachi Air Conditioning developed a residential dual fuel heat pump system that combines an air source heat pump and a gas furnace. The manufacturer says the furnace is designed to ensure there is no compromise in heating performance, even when temperatures are extremely low.

Scientists in Canada have combined PV power generation with water purification based on capacitive deionization (CDI), which is claimed to have low operational cost, enhanced energy efficiency, and less water rejection than conventional purification techniques. The solar-powered system prototype is able to produce more water than a conventional CDI system on a sunny day.

Sharp’s new IEC61215- and IEC61730-certified solar panels have an operating temperature coefficient of -0.30% per degree Celsius, with 21.51% efficiency.

Tesla has launched the Powerwall 3 battery with an energy capacity of 13.5 kW and continuous on-grid power of 11.5 kW, featuring dimensions of 110 cm x 61 cm x 19.3 cm and a weight of 130 kg.

Carrier, a US-based heating solutions provider, has introduced a new line of high-temperature heat pumps with capacities ranging from 30 kW to 735 kW, with hydrofluoroolefins as a refrigerant.

EnerVenue says the battery’s efficiency ranges from 80% to 90%, depending on the cycle rate, and claims that its energy density per square foot is equal to or even better than lithium-ion batteries.
