residential PV

Ikea is expanding its energy offerings in Germany with a dynamic electricity tariff in partnership with Svea Solar, changing every 15 minutes based on day-ahead market prices and available even to customers without its PV systems, storage solutions, or heat pumps.

IEA-PVPS Task 15 has launched its first modeling intercomparison exercise on coloured building-integrated photovoltaics (BIPV) and is inviting PV modelers and researchers to evaluate their methods using real-world performance data.

The country reached a cumulative installed PV capacity of 43.5 GW at the end of December, according to new figures released by Italian grid operator Terna.

A research group from the European Commission Joint Research Centre has developed a new PV climatic classification, the first to address annual yield and performance ratio. Their work resulted in 10 globally applicable clusters. “It challenges the assumption that many more classes are needed to capture PV-relevant climate,” the researchers said.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that Central Europe, led by Germany, experienced strong solar generation in December due to clear skies from a blocking weather pattern, while Iberia, Scandinavia, and Eastern Europe saw reduced irradiance from storms and cloud cover. Late-month Arctic cold and snowfall further suppressed PV output in Eastern Europe through snow soiling, exacerbating already weak solar conditions.

The launch of the new product suggests Tesla could renew its focus on residential solar and expand U.S. lease options with Powerwall.

Axinar has launched SolBox, a direct PV water heating system that powers electric resistance accumulators without thermal collectors. It’s designed for homes and businesses, offering real-time monitoring, MPPT optimization, and automatic grid backup.

Researchers from Australia’s national science agency are working with Malaysian authorities to assess how different battery chemistries perform under tropical conditions, including high temperatures, humidity, and corrosion, and how these factors affect durability, safety, and cost effectiveness.

Once considered isolated incidents, spontaneous glass breakages in solar modules are becoming more frequent, highlighting the limits of some manufacturing choices and the need for closer quality control.

The new IQ9N-3P microinverter utilizes gallium nitride technology to deliver 427 VA of peak power and 97.5% efficiency for the 480 V three-phase commercial market.
