Global PV oversupply accelerates consolidation, regional price divergence

The global market for solar panels is making far more than anyone needs right now, and that oversupply is expected to continue for another year or two. China alone can produce more solar cells than the whole world uses in a year. That's pushing prices down, but not evenly: equipment sold into markets with trade barriers or local-content rules, including the US and Europe, is starting to cost more than equipment sold elsewhere, because buyers there are paying for compliance and supply security rather than just the lowest price.

This matters if you're planning a solar installation, because the panels, inverters, and batteries you'd buy are all affected differently. Panel prices are so low that most manufacturers are losing money, which is unsustainable long-term. China is also phasing out an older panel technology (called PERC) starting in 2027, which means some panels on the market now could become outdated stock sold off cheap before that deadline. For inverters, a bigger near-term issue in the US is a Federal Communications Commission rule restricting new foreign-made inverter models, which could complicate project approvals if equipment gets swapped out partway through installation. Battery storage is in an earlier stage of this same cycle: battery makers are generally still profitable, and high-quality cells remain in short supply even as more companies pile into the market.

None of this requires any action from you today, but if you're shopping around for a home solar or battery system, it helps to know that price alone may not reflect quality, warranty support, or how long equipment will stay current before being phased out.
