New provisions in the Philippines define interconnection standards, the certification of compliance requirements, and pricing methodologies, among other matters.

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 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.

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.

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.

Sunova Solar is offering five versions of its new solar panels, with power outputs from 555 W to 575 W and efficiencies ranging from 21.4% to 22.2%. They have a temperature coefficient of -0.31% per degree Celsius.

Japanese scientists have described the steps that need to be taken to improve the average efficiency of CIGS solar modules, from around 18.5% at present to more than 20%. They presented all of the critical technical factors that are currently holding the tech back from broader market adoption.

The International Energy Agency Photovoltaic Power System Programme has standardised guidelines for operation and maintenance programs for large-scale solar plants. It defines O&M performance indicators and standard O&M operator services, as well as tools to analyse PV plant performance and safety.

Indian scientists have designed a new all-perovskite tandem solar cell configuration that can reportedly achieve higher efficiencies than similar devices built with the same materials. The top perovskite cell has a wide bandgap of 1.75 eV and the bottom perovskite cell has a bandgap of 1.25 eV.

German researchers have created an algorithm to predict and identify string yield losses or underperforming strings without additional weather data. It could be used to inspect modules, strings, arrays, inverters, and transformers.
