Irish solar rises in 2025 as government plans €18.9 billion of grid upgrades
Provisional data from the Sustainable Energy Authority of Ireland (SEAI) for 2025 showed that monthly utility-scale solar generation increased from an average of 0.73 TWh in 2024 to 0.99 TWh in the first nine months of 2025.
Too much to choose from, too little to decide
Market pressure in the solar and storage sectors often favors low-cost solutions, but long-term success depends on balancing price, quality, and reliability for assets designed to operate for decades. Numerous examples, from low-grade silicon modules to residential hydrogen and redox flow storage, show how technically ambitious products can fail when costs, complexity, or durability are misjudged.
