Residential PV

Solarwatt has launched six new inverters and batteries as part of its Solarwatt Home line and outlined its future strategy. The German company, currently in transition, recently closed its solar module plant in Germany and announced staff reductions.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that blocking high pressure over Eastern Europe in October created a strong east-west divide in solar irradiance across the continent. This led to notably lower irradiance due to persistent cloud cover and rainfall, especially across the Iberian Peninsula and northern Italy.

A group of scientists from a major Chinese grid operator have proposed to use an enhanced version of the particle swarm optimization algorithm to adjust inertia and damping coefficients in batteries linked to PV systems. Their approach was validated through a series of simulation and was found to enhance transient performance.

Spain-based Tecnalia has designed a balcony that integrates renewable energy systems, ventilation, and smart energy management. The innovative structure allows for the incorporation of sustainable technologies, providing both energy efficiency and environmental benefits.

The Chinese manufacturer said its new Heco series uses propane (R290) as a refrigerant and includes five models with a nominal capacity ranging from 6 kW to 17 kW.

French companies Le Triangle Horizon and SunStyle International are offering a new carport based on solar tiles for areas protected by environmental regulations.

Scientists in Egypt have created an anti-soiling coating for solar panels by mixing ethanol, deionized water, ammonium hydroxide and tetraethyl orthosilicate. They tested a coated panel outdoors for ten months and found that the panel showed a 64.7% higher current compared to reference modules without coating.

UK-based Wondrwall says its new heat pump has a coefficient of performance of up to 4.99, with an inlet-outlet temperature of 30 C to 35 C. The system is based on the company’s AI-powered Home Energy Management System (HEMS) to efficiently manage household energy flows.

Software company Aether Energy has launched in Europe to support residential and commercial rooftop solar PV installer businesses, from pre-sales to after-sales and energy monitoring. It recently secured seed capital to finance its plan to expand its business.

The Ontario Court of Appeal has rejected a claim from the province’s Independent Electricity System Operator (IESO), which accused solar suppliers with feed-in-tariff (FIT) contracts of breaching their agreements by repowering their systems.
