MoIT is preparing a new policy package for rooftop solar and battery storage, but direct incentives are still undecided. For households, PV remains the first savings pillar.
VIR reported on 8 July that the Ministry of Industry and Trade (MoIT) is preparing a new policy package to accelerate rooftop solar, expand battery storage investment, and study time-of-use pricing for large residential consumers. The key point is that direct incentives for rooftop solar still have not been issued because budget resources are not ready, even though new legal mechanisms are already being introduced.
The message is not that families should wait for batteries before considering solar. The more accurate message is that rooftop PV remains the first savings layer, while ESS should only be added when it solves a clear household problem. If the main goal is to lower the electricity bill, the decision should start with actual consumption data, daily usage timing, and the share of load that can be self-consumed during the day.
The article says MoIT was tasked with drafting a decision on rooftop solar incentives, which once included two support options: partial investment subsidies from the state budget and preferential loans for household solar installations. However, the Ministry of Finance said the budget is not yet ready for direct subsidies, and the question of which financial institutions should provide concessional lending is still being discussed. In other words, homeowners should not base an investment decision on a support package that does not yet have a clear issuance date.
MoIT is also following another direction: accelerating battery storage to match a power system with a rising share of renewables. According to the article, the revised national power plan targets roughly 10,000–16,000 MW of storage capacity by 2030. The system operator also said the North is being prioritized first because supply-demand stress is higher there, while Central and Southern Vietnam do not yet face urgent storage needs.
For households, one important detail is that MoIT has no immediate plan to apply time-of-use pricing for residential customers. Without TOU tariffs for households, the value of PV still mainly comes from daytime self-consumption and from reducing the amount of electricity bought from the grid. If a family uses most of its power in the late evening, batteries can move part of the solar output into that period, but ESS remains a support layer for PV, not the starting point of the purchase decision.
Another important shift in the article is the load shape of the system itself: in the past, demand could peak both at midday and in the evening, but as solar has grown rapidly, midday demand has flattened and the evening peak has become the main pressure point. For households, that means a well-designed rooftop PV system works best when it matches daytime loads such as air conditioning, water pumping, laundry, working from home, or EV charging.
From a homeowner’s budget perspective, the article is not telling families to wait for policy to finish before installing. It is telling them that policy is moving toward treating rooftop solar and storage as part of a larger power-system problem. So the best decision today still starts with the electricity bill, daytime demand, and roof quality. Once those are clear, PV becomes a real bill-saving tool; ESS should only follow if it makes PV more useful in the evening or during outages.
Soft CTA: If a household wants to know whether PV fits its roof, start with the last 30 days of electricity bills and an hourly usage schedule; that is the fastest way to decide whether PV should come first or whether ESS deserves consideration.
