Enphase releases new control software for its IQ8, IQ9 microinverters
The US company said its Power Control software is designed to help installers reduce costs and streamline interconnection. Among its features is the ability to control aggregate system exports through software-based limits.
An ever-changing market: Delving into the heart of power purchase agreements
Cross-border VPPAs expose corporates to Basis Risk, causing settlement price gaps and weakening confidence in these hedging tools, contributing to a 35% drop in European PPA signings in 2025 amid complex market conditions. The market is shifting toward more structured, domestic, and hybrid PPAs, supported by BESS and modern IPPs, to better manage risk and realign buyers, sellers, and lenders.
Spain’s behind-the-meter storage grows 119% in 2025
Spain installed 339 MWh of storage linked to PV self-consumption in 2025, up 119% year on year, according to APPA Renovables. The country added 1,214 MW of new self-consumption capacity, bringing the total to 9.6 GW.
Octopus Energy invests $1 billion in California clean technology
Octopus Energy will acquire a solar and storage project in California that is expected to be operational by July as part of its investment. The UK-based company, active across major markets in Europe, Australia, China and the United States, says California’s clean technology sector will “bring innovation, growth and returns to the UK.”
Fraunhofer ISE achieves 34.2% efficiency with III-V germanium PV module
Fraunhofer scientists have announced two efficiency records for III-V tandem modules. The team says its 34.2% efficiency III-V germanium PV module is the most efficient solar module in the world, while its 31.3% efficiency III-V silicon PV module is a record in its class.
The impact of agrivoltaics on soil properties
New research shows how agrivoltaic systems can reshape soil by altering moisture, temperature, and microbial activity, creating heterogeneous zones under and between panels. Proper design and management can boost soil health and crop resilience, especially in degraded or arid regions, though long-term effects remain uncertain.
World’s largest solar-plus-storage project completes initial grid synchronization
The first phase of the MTerra solar project in the Philippines, set to be the world’s largest solar-plus-storage site once completed, has achieved initial synchronization and energization to the Luzon grid. Project developers are anticipating the project to being exporting power by the end of the month.
Guatemala PEG-5 tender draws 51 bidders for 4.7 GW of capacity
Guatemala’s Generation Expansion Plan 5 (PEG-5) tender has drawn 51 bids totaling nearly 4.7 GW – more than triple the 1.4 GW sought – with around 2 GW of solar projects, including hybrids with storage, competing for long-term supply contracts starting between 2030 and 2033.
What happens when type-C cracks strike photovoltaic modules
An international research team used high-resolution electroluminescence imaging to quantify type-C cracks in 100 PV modules after 11 years of operation, linking crack distribution to real-world power loss. Concentrated cracks within individual cells were found to cause disproportionately high losses, highlighting the importance of cell-level crack analysis for effective PV maintenance.
Chinese Academy of Sciences unveils 101 MW compressor for compressed air energy storage
The new compressor is described as the world’s most powerful single-unit compressed air energy storage (CAES) system, with a maximum discharge pressure of 10.1 MPa and an efficiency of 88.1%.
