Sigenergy unveils 2.68 kWh battery for balcony PV
Sigenergy has launched a 2.68 kWh balcony storage system with four MPPTs and up to 4 kW of PV input. The scalable LFP solution offers 800 W grid output, 1.2 kW backup power, and expansion up to 18 kWh per tower.
Iraq’s largest solar project enters trial operation
Iraq’s Ministry of Electricity says an initial 61 MW from the first unit of a planned 1 GW solar project has commenced. The project is being developed across four 250 MW units, with final commissioning currently scheduled for 2028.
Estonia deploys 105 MW of solar in 2025
Estonia’s cumulative solar capacity reached around 1,430 MW by the end of last year. Year-on-year installations slowed as the country’s solar market begins to saturate, with future growth expected to be driven by supplementing solar parks with batteries.
Mitsubishi Electric Trane announces new heat pump line for hydronic heating
The systems deliver outlet water temperatures up to 74 C, operate in ambient temperatures from -25 C to 43 C, and can be cascaded in groups of up to 16 units for larger commercial applications.
Optimizing solar EV stations for maximum impact
A new report from the International Energy Agency Photovoltaic Power Systems Programme (IEA PVPS) Task 17 outlines how photovoltaic systems can be effectively integrated with electric vehicle charging infrastructure through optimized sizing, intelligent control, and site-specific design.
CEA-Ines, 3Sun build heterojunction solar modules based on UV downshifting
The new heterojunction solar module concept is based on co-extruded EVA/POE/EVA (EPE) encapsulant with UV downshifting (UV-DS) films, which convert harmful UV light into blue light, protecting cells and slightly boosting short-circuit current by 1.5–1.75%.
Hybrid perovskite solar cell generates power from sun and rain
Researchers at ICMS in Seville have developed a hybrid perovskite solar cell that generates electricity from both sunlight and raindrops, using the photovoltaic and triboelectric effects. A fluorinated CFₓ polymer layer enables water resistance, triboelectric energy harvesting, and high light transparency without reducing solar cell efficiency.
How to address imbalance datasets in solar panel dust detection
Researchers from South Korea improved solar panel dust detection by using SMOTE and stable diffusion (SD) augmentation, with SD boosting detection accuracy from 76.5% to 98.9% while preserving spatial realism.
Iraq slashes solar import tariffs to 5%
The Iraqi Customs Authority has cut customs duties on solar energy systems from 33% to 5% – covering PV panels, inverters, cables, and lithium batteries – to accelerate solar adoption, following financing support from the Central Bank of Iraq.
Singapore raises 2030 solar target to 3 GW
Singapore has increased its 2030 solar target by 1 GW after surpassing the original 2 GW goal before the end of last year.
