California-based Apparent Inc. has unveiled a new water heater that can reportedly offset 100% of a home’s water heating cost. The system uses low-voltage DC electricity generated by conventional solar panels and a cloud based, machine learning platform that manages energy in real-time.
The Chinese manufacturer said the product line includes five models with outputs ranging from 25 kW to 50 kW, supporting charge and discharge currents of up to 150 A.
While solar modules and batteries have become icons of rapid progress, most energy models are still stuck in the past. A new global analysis shows that the cost of renewable energy has fallen far faster than expected. Solar PV, wind power, and battery technologies have already reached price levels that models once placed many decades ahead – a misplaced pessimism that risks misdirecting billions in climate investment and could distort long-term defossilization strategies.
The Chinese company says that its new ESA series is available with a hybrid inverter ranging from 3 kW to 10 kW and storage capacities of 5 kWh to 48 kWh. The IP66-rated product supports an MPPT current of up to 20 A on the PV side and allows 200% PV oversizing, according to the manufacturer.
Researchers in China developed a large-scale PV-thermal heat pump system using a liquid overfeed method that reportedly improves both thermal and electrical efficiency. Field tests showed up to a 4.81% boost in power generation and significantly reduced pressure losses compared to conventional systems.
The PPA price for pure photovoltaic projects has fallen by 20% over the past year, making such contracts less competitive. However, clear structures for bankable hybrid PPAs are now beginning to take shape, says Pieter van der Meulen, Senior Account Manager at LevelTen Energy, in an interview with pv magazine.
Scientists in China have developed a new deep learning model based on the so-called “You Only Look Once” algorithm, which requires only one forward propagation pass through the neural network to make predictions,
The German company said its new device features a DC input supporting up to 3 kW of photovoltaic power. The heating output can be continuously adjusted between 0 W and 1,000 W. Priced at €549 ($635) including VAT, the heating element is designed for hot water storage tanks with capacities of up to 500 L.
Open Climate Fix says its Quartz Solar tool saves Great Britain’s grid operator GBP 30 million ($39 million) per year through more accurate forecasting, which reduces the reserve capacity needed for balancing the electricity system. The non-profit company has used machine learning techniques with satellite, weather and historical generation data to reduce forecasting errors by half.
From ESS News China Petroleum & Chemical Corporation (Sinopec) and South Korea’s LG Chem have signed a joint development agreement to advance key materials for sodium-ion batteries, as the technology moves closer to mass commercialization. Under the agreement, the two companies will collaborate on developing cathode and anode materials for sodium-ion batteries, targeting applications in […]
