The United Nations Development Programme (UNDP) says emergency generators, some powered by solar panels, are being deployed as Cuba struggles to restore electricity after the storm.

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.

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.

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.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that North America experienced a highly variable solar performance in October, as a strong high-pressure system boosted irradiance across the eastern regions while cooler, cloudier conditions reduced solar potential in the Pacific Northwest.

The Italian manufacturer said its new WWMG heat pump system has a coefficient of performance of up to 4.98 and an energy efficiency rating of 16.30 BTU/Wh.

UK researchers find that smart, centrally controlled air-source heat pumps could slash peak electricity demand. The technology not only keeps homes comfortable but also boosts grid flexibility and cuts emissions.

GSE Intégration has introduced a new version of its ground-mounted photovoltaic structure, the GSE Ground System Evolution. It is designed for faster installation and compliance with France’s soil conservation laws.

Japanese utility Tohoku Electric Power is using Sharp’s residential batteries and AI-powered energy management systems to balance grid demand and optimize household solar energy use. Customers in the program can earn points redeemable for local products.
