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.
