The new single-phase off-grid inverters have an AC output power ranging from 3.6 kW to 6 kW, Deye reports. The systems feature a maximum efficiency of 97.6% and a European efficiency rate of 96.5%.

Enertopia has developed a solar module cooling system that uses a moisture collection layer to transfer heat while capturing water for irrigation in arid regions. The design channels heat from the panel to a liquid transfer system, improving efficiency and water use.

Carrier, a heating solutions provider, said its new AquaSnap 61AQ heat pump system can deliver high-temperature heating up to 167 F at outdoor temperatures as low as -13 F. The new product is available with capacities ranging from 40 kW to 140 kW.

At the World Future Energy Summit in Abu Dhabi, pv magazine spoke with two OPIS analysts about the current and projected price trajectory in the global supply chain. According to their analysis, overcapacity remains difficult to be kept in control, which makes an increase in solar module prices very unlikely, at least in the near future.

Developed at the U. S. Ames National Laboratory, the novel magnetocaloric heat pump utilizes gadolinium as the working medium and reportedly matches current vapor-compression heat pumps for weight, cost, and performance. The system is based on a packed-particle bed active magnetic regenerator, a magnetic source composed of permanent magnets and high permeability magnetic steel.

Carrier, a heating solutions provider, introduced a new 4-14 kW line of heat pumps with a coefficient of performance of up to 4.90. The system use propane as the refrigerant and can reportedly reach leaving water temperature of 167 F.

Techno-economic analysis conducted by NREL researchers has shown how perovskite-silicon tandem solar modules could currently hardly compete in cost with incumbent PV panels. Production costs for U.S.-made tandem products were found to range between $0.29/W and $0.42/W, with module efficiencies ranging from 25% to 30%.

Stanford University professor Mark Z. Jacobson spoke to pv magazine about recent research work showing that California could easily rely on a wind-water-solar-dominated large grid. He says the state’s current electricity prices are high because of several reasons that have nothing to do with renewables.

Now available in the North American market, the manufacturer says these heat pumps work with new AI technology and reportedly perform better when connected to a PV system.

The proposed cell is based on indium gallium phosphide (InGaP), indium gallium arsenide (InGaAs) and germanium (Ge) and has an active area of 0.25 mm2. It can be used for applications in micro-concentrator photovoltaics (CPV).
