Residential PV

Leapton says its new panels have a temperature coefficient of -0.30% per C and an efficiency of up to 23.14%. They come with a 30-year power output guarantee for 87.4% of the initial yield.

A Dutch trade association has informed parliament about a possible wave of closures and bankruptcies in the rooftop solar segment in the Netherlands.

A new study by Indian government think tank NITI Aayog outlines the renewable energy potential for all states to meet their renewable purchase obligations. The report, backed by the Ministry of New and Renewable Energy (MNRE), also details the storage that will be required for grid balancing.

Researchers in Italy have investigated the potential of deploying energy communities based on east-west PV systems and have concluded that these projects, despite their lower energy yields compared to south-oriented installations, show higher shared energy values. They also warned, however, that the presence of a net metering scheme is crucial to make the east-west layout the preferred option.

The Economic Community of West African States (ECOWAS) is offering grants from $10,000 to $250,000 in the second funding round of the Regional Off-Grid Electricity Access Project (ROGEAP) to develop off-grid solar in 13 West African and sub-Saharan African countries. The application deadline is June 23.

In its second monthly column for pv magazine, the IEC highlights the research on flexible crystalline silicon solar cells led by researcher Zhengxin Liu, the Vice Chair of IEC Technical Committee 82, which prepares standards for solar PV energy systems.

Scientists in China have tested the influence of panel row spacing in increasing a PV system performance in a full-scale outdoor PV array experimental platform. They found that larger row spacing plays a limited role in improving thermal convection, observing that solar irradiance and wind speed are the key parameters for optimal PV system design.

The latest government installation figures reveal a slower start to the year for the United Kingdom, with small-scale installations accounting for the majority of additions. As the UK General Election approaches, there are calls from industry for the next government to act quickly on the issues hindering capacity expansion.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that a strong polar jet stream and a record-breaking heat dome in May resulted in a stark contrast in irradiance patterns across North America. The western and central USA, along with Mexico, experienced higher than normal irradiance, while the Gulf and East Coast regions faced lower irradiance.

The novel heat pump concept combines solar energy with chemical storage and reportedly consume 75% less electricity than conventional heat pumps. The system relies on a battery and a heat storage tank that can be used either separately or simultaneously, depending on the outdoor conditions.
