Solar power in Vietnam has grown explosively, with rooftop installations soaring after the 2020 feed-in tariff, but the grid infrastructure wasn't ready for that surge, causing frequent curtailment and wasted energy. Some argue we should keep pushing renewables aggressively and fix the grid later, while others say we need a more balanced mix with thermal or gas power to ensure stability. I've seen the numbers—solar can be cheaper per kilowatt-hour, but only if we can actually use it when the sun shines. So, is it wise for Vietnam to prioritize solar expansion even if it means occasional power cuts during peak demand?
