European solar module prices continued their upward trajectory in July 2026, but the market showed clear signs of softening demand as buyer sentiment cooled for the second consecutive month, according to the latest PV Index data from solar trading platform sun.store.
The PV Purchasing Managers' Index (PMI) – a key barometer of buyer sentiment and purchasing intentions – slipped to 65 in July, down from 67 in June and well below May's reading of 70. This marks the softest reading in months and sits slightly below the historical average of 67. While still in expansionary territory, the decline signals that European solar buyers are adopting a more cautious outlook heading into late Q3.
Premium Modules Lead the Price Charge
Despite the cooling demand signal, module pricing continued to split sharply along the premium line in July. Full Black modules posted the strongest gain of the month, rising 8% month-over-month to €0.138/Wp, overtaking Back Contact modules to become the most expensive segment in the index. Back Contact modules followed at €0.135/Wp (+4% m/m), while TOPCon monofacial modules edged up 2% to €0.128/Wp.
The premium segments have been on a remarkable run throughout 2026. Since January, high-efficiency solar modules with over 23% efficiency have seen a 26.1% price spike to €0.145/W, while mainstream modules have increased by 28.6% to €0.135/W. Full-black variants across mainstream PV technologies have risen by 23.1% to €0.160/W.
TOPCon Bifacial Bucks the Trend
In a notable divergence, TOPCon bifacial modules continued their easing trend in July, dropping 5% month-over-month to €0.110/Wp. This marks the third consecutive month of divergence between the two TOPCon variants – an unusually persistent split for two closely related products. For buyers specifying standard utility-scale modules, bifacial remains the cheaper route by a widening margin.
According to pvXchange, solar module prices were largely unchanged in July 2026, with improved availability across most product categories. The main exception was high-efficiency back-contact modules (above 24%), for which demand continued to exceed supply, leading to shortages in higher power categories. However, because BC modules still account for a relatively small share of the overall market, their pricing has had only a limited effect on the broader market.
What's Driving the Price Increases?
The price rally has been driven by a combination of factors. China's elimination of VAT export rebates on solar modules and silicon wafers, effective April 1, 2026, forced manufacturers to reset their pricing logic. The lowest price levels had become structurally unsustainable, particularly for Tier-1 players operating at scale.
Increased costs incurred at the very beginning of the supply process also played a key role. In the first weeks of 2026, the price of silver experienced an increase of over 150%, thus being important in terms of the goals for the production of various kinds of panels. With regards to polysilicon prices, they have stopped decreasing and may have actually begun to rise in certain areas.
In addition, the freight cost of containers in East Asia and Northern Europe increased sharply, while the costs of the routes to the Mediterranean became even higher than those of routes to Northern Europe after shipping companies controlled the capacity of their ships and re-routed them via Cape of Good Hope.
Buyer Sentiment: From Euphoria to Caution
The cooling of buyer sentiment represents a notable shift from the spring. In May, the PV PMI had jumped to 70, its highest level in more than a year, with 49% of respondents planning to increase purchases and only 10% anticipating reducing procurement. By July, the share of buyers planning to cut purchases had risen to 16%, up from May's low of 10%. Only 46% now plan to buy more, down from 49% in May and 48% in June.
The shift reflects a market in transition. After two years of unprecedented price declines, the sudden reversal has felt abrupt. Buyers who had grown comfortable delaying decisions, confident that prices would continue to fall, are now facing a different reality. Some large procurement organizations have already started securing volumes earlier again, especially for utility-scale projects scheduled for delivery in late 2026 and 2027.
Market Divergence and the Premium Pull-Ahead
One of the most striking features of July's data is the widening gap between premium and standard modules. Full Black is now the most expensive module segment in the index, and the premium over standard TOPCon continues to widen. Buyers holding out for lower standard-module pricing are being rewarded; those specifying premium categories are not.
Inverter pricing, meanwhile, remained broadly stable in July, with hybrid systems drifting slowly lower. Larger commercial units remain by some distance the most competitively priced part of the inverter market on a per-kW basis.
What to Expect
Looking ahead, industry observers expect TOPCon module prices to remain stable or edge lower this year as manufacturers increase production to improve factory utilization amid slowing market growth. In contrast, limited supply and sustained demand are expected to keep back-contact module prices stable or slightly higher.
"Further price increases are therefore unlikely this year, at least for TOPCon modules," said Martin Schachinger of pvXchange. "Prices for these products have already stabilized."
The European solar market is entering a new phase where procurement decisions are increasingly driven by logistics, policy, technology, and long-term project economics rather than price alone. As prices stabilize, suppliers are differentiating themselves through supply chain resilience and regulatory compliance. For buyers, the message is clear: premium modules are still setting the pace, but the demand signal has cooled since the spring. The era of unlimited cheap inventory may be ending, and strategic procurement is becoming more important than ever.
