rooftop solar

The US-based automotive manufacturing company said its new storage system offers the option of integrating with PV systems. It can be scaled to reach a capacity of up to 35.4 kWh, which the company said would enable approximately 20 hours of storage.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that low-pressure systems caused cloudier skies and reduced irradiance in Southern and Western regions in September, while areas further north and east enjoyed sunnier weather. A series of low-pressure systems centered over France led to the biggest drop in irradiance by up to 25%.

Researchers from Canada’s Western University assessed eighteen case studies across thirteen US states and found in areas an economic case for disconnecting from the electricity grid in some areas with high solar irradiation and high electricity rates. They say economic grid defection and utility death spirals are becoming salient issues in the US.

Hungary’s Ministry of Energy says it will support more than 25,000 households with residential solar installations through its subsidy scheme, which launched earlier this year, taking the total number of installations to in excess of 300,000.

Swiss module manufacturer Freesuns has installed 33,300 of its solar roof tiles on three historical buildings in the Swiss town of Neuchâtel.

Norway-based Evert said its new solution can simplify installing solar PV, energy management, and electric vehicle charging by combining multiple devices into one unit bundled with software. It is made for the European residential and commercial markets, and expected to be available in mid 2025.

Germany installed 960 MW of solar in September, bringing its cumulative PV capacity to more than 94.52 GW.

The new multifunctional PV window concept aims to produce electricity while providing over-heating protection for better indoor thermal and visual comfort. It consists of an insulating glazing unit with bifacial crystalline silicon solar cells strips and embedded venetian blinds that act as reflectors for the rear side of the cells.

Conceived an international research group, the proposed model uses the convolutional neural network (CNN) architecture U-Net for image segmentation and the the CNN architecture InceptionV3-Net for fault classification.

Battery and inverter manufacturer Redback Technologies has bounced back from a tumultuous start to the year – including a short stint in voluntary administration – with the launch of a new range of solar and energy storage products.
