rooftop solar

California’s highest court granted review to a lawsuit challenging a “regressive” rooftop solar policy called NEM 3.0.

The Austrian authorities are granting a rebate of €200 ($214)/kWh to residential and commercial storage systems.

New research from Germany showed that PV-powered heat pumps could require less surface than their solar thermal-driven counterparts in district heating networks. The scientists also found that increasing energy prices would have a minimal impact on the viability of both concepts.

S-5!, a supplier of mounting systems, plans to release two new mounting components for rooftop PV systems, including a new mount that allows for module-level power electronics to be attached directly to solar panel frames.

India’s cumulative PV installations hit 75.58 GW at the end of February, according to the latest figures from the nation’s Ministry of New and Renewable Energy (MNRE).

The new heat pumps use R-454B as a refrigerant and have a size ranging from 2 tons to 5 tons. Their coefficient of performance (COP) ranges between 3.24 and 3.40, according to the manufacturer.

The Japanese manufacturer said its latest power semiconductor module is based on a compact insulated-gate bipolar transistor (IGBT) and is designed for large capacity industrial power converters voltage of 2,300 V.

Greenfuel Energy’s new lithium batteries for residential applications are available in 12.8 V 100 Ah, 25.6 V 100 Ah, and 48 V 100 Ah configurations, with 1 kW to 5 kW of power.

A report from Climate Action Network Europe says residential rooftop solar installations in the EU have grown by 54% year-on-year, but warns a lack of grid capacity and specific strategies for rooftop solar development means member states are not keeping pace with the demand.

Fluvius, Belgium’s electricity grid operator, says it will compensate residential PV systems at €10.60 ($11.49) per kVa if they are not reconnected within 30 working days after a curtailment event.
