Customisable sticker to turn solar panels into advertising billboards
An Italian startup has created a fully recyclable sticker that can be used to cover solar panels on rooftops or facades. It replicates high-definition images that can help to improve the aesthetics of solar arrays or turn PV facades into advertising billboards.
Growatt unveils new inverters for residential off-grid PV systems
Growatt’s new 6 kW inverters have an efficiency rating of 93% and offer 12,000 VA of surge power, up to 500 V of input voltage, and 8 kW of PV input capacity.
PV system fires potentially exacerbated by gap between solar panels, rooftops
Norwegian researchers have published a new study showing that the space between solar panels and rooftop surfaces might play a critical role in contributing to PV system fires.
Panasonic unveils vehicle-to-home system for PV-powered homes
Panasonic claims that its new vehicle-to-home system can increase the self-consumption rate of residential solar and storage capacity to 90%.
How variable is rooftop solar power?
A research group has developed a new methodology that shows PV systems located in the same area could have similar distributions of power ramps. Their three-step method could be used for the dimensioning of rooftop arrays and the scheduling of daily operations.
Philippines increases net-metering size limit for renewables to 1 MW
New provisions in the Philippines define interconnection standards, the certification of compliance requirements, and pricing methodologies, among other matters.
Photovoltaics vs. concentrated solar power
Omani researchers have compared the performance of PV and concentrated solar power (CSP) in terms of energy generation intensity and the effective use of land at low latitudes near the Tropic of Cancer. They described nine project typologies and ranked them with three different simulation tools.
Freight costs edge toward 4% of solar module costs, near pre-pandemic levels
Freight costs fell for the 39th straight week to account for roughly 4% of solar module costs – close to pre-pandemic levels. PV consultant Asier Ukar tells pv magazine that this trend will likely continue over the short term.
Martin Green’s solar cell efficiencies at a glance updated
A research group led by Professor Martin Green has published Version 61 of the solar cell efficiency tables. The tables include a world record for a silicon heterojunction cell, announced by Longi earlier this week, as well as five more new results.
Lithium-vanadium battery for renewables storage
AMG Advanced Metallurgical Group has energised its first hybrid storage system based on lithium-ion batteries and vanadium redox flow batteries in Germany. The system reportedly combines the advantages and electrochemical properties of both storage technologies.
