Residential PV

A Spanish-Chilean research team has found that microbial biofilms in the Atacama Desert can significantly contribute to the soiling of photovoltaic modules, reducing short-circuit current by up to around 30% under accelerated laboratory conditions. The study highlights microorganisms as active agents in PV soiling and suggests they may influence optical losses, cleaning efficiency, and future mitigation strategies in arid, high-irradiance solar regions.

The two companies will develop XFRA, a distributed network of compute nodes connected to homes with smart panels, batteries and optional solar generation, in partnership with Nvidia and homebuilders like PulteGroup,

The German manufacturer has launched an integrated energy system combining inverter, storage and energy management in a modular, scalable solution for new and existing PV installations. The system supports AC/DC coupling, backup power and smart energy optimization.

Credential compromise attacks allow adversaries to gain unauthorized access to PV systems by stealing or guessing valid login credentials, enabling them to manipulate operations, disrupt monitoring, or take control of critical assets. These attacks can lead to operational instability, reduced energy production, and safety risks, making strong authentication and access control essential for system resilience.

Free midday electricity schemes aim to shift household demand into periods of high solar PV generation, reducing midday surplus and evening fossil-fuel ramp-up. Research on Australia’s Solar Sharer program suggests such incentives could significantly improve renewable utilization, but outcomes depend on consumer behaviour, load shifting, and rebound effects.

Entering a competitive small-scale energy storate field is Chinese maker Mova, well-known for its kitchen applicances and growing robotic homewares including vacuums and more.

The German manufacturer said that its new air-to-water heat pump system uses propane as a refrigerant and is available in three variants with outputs of 5 kW, 7 kW, and 11 kW. The new product can reportedly achieve a coefficient of performance of up to 4.93.

Scientists in Chile have developed a low-cost, easy-to-deploy hydrogen system powered by end-of-life solar panels. The residential solution reportedly achieves a levelized cost of hydrogen of approximately $5.8/kg.

Analysis of longitudinal survey data has explored the link between intended and actual solar panel adoption in UK households. It finds that while most households that had intention of installing solar in 2012-13 were yet to do so by 2021-22, serious intention to install solar still increases the likelihood of adoption more than other factors such as income and environmental perceptions.

Atmoce’s new MI microinverter series connects two PV modules per unit while still providing module-level power optimization.
