Residential PV

The new heat pumps use R-454B as a refrigerant and are specifically designed to be matched with Johnson Controls’ residential gas furnaces. Their size ranges from 1.5 tons to 5 tons and their coefficient of performance (COP) spans between 3.24 and 3.40, according to the manufacturer.

The International Energy Agency (IEA) Photovoltaic Power Systems Programme (PVPS) has published a wide-reaching snapshot of the global PV market, covering installations, manufacturing, policy trends, and grid integration.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that dust storms and slear skies led to contrasting March Solar Performance in West Asia. The Arabian Peninsula experienced humid winds and dust storms that reduced solar irradiance to 90% of typical levels for the month.

EcoFlow has launched a new air-to-water heat pump for residential applications. The new product, equipped with R290 refrigerant, is available in 9 kW and 20 kW versions. The US-headquartered manufacturer has also developed a new smart immersion heater, which uses surplus solar energy to heat up water. It is compatible with all available rooftop PV systems.

A Chinese research group has sought to understand the relative performance of two weather prediction techniques based on ensemble modeling for solar energy forecasts. The scientists applied the two methods in combination with three classical post-processing methods.

AleaSoft Energy Forecasting says that all major European electricity markets, except for Italy, have recorded negative hourly electricity prices for the second straight week. However, the Spanish consultancy notes that prices generally remain low.

US news outlets have reported resident concerns about leaked toxins from solar facilities in Texas that were damaged by a hailstorm. The Solar Energy Industries Association (SEIA) has rejected the reports, which contained categorically false information.

India’s Ministry of New and Renewable Energy (MNRE) has released draft guidelines for the PM Surya Ghar: Muft Bijli Yojana scheme, which aims to install rooftop solar plants in 10 million households, with subsidy support from the central government.

The Chinese manufacturer said its new frameless module can be installed on a balcony through nylon cable ties, without the need for any mounting structure. The new product features a power output of 200 W and a power conversion efficiency of 16.2%.

Researchers in India have simulated a 4 kW solar power-based hybrid electric vehicle (EV) charging station using a three-stage charging strategy and found that the station is capable of charging 10–12 EVs with 48 V 30 Ah lithium-ion batteries.
