Introduction

European solar buyers enter Week 40 with stable module benchmarks, stronger evidence of inverter manufacturing scale, and rapidly changing storage use cases. InfoLink reported unchanged module pricing in Europe, while Risen Energy advanced its heterojunction roadmap and First Solar’s manufacturing record highlighted the commercial importance of technology and supply-chain diversity. In inverters, European-headquartered manufacturers are forecast to ship almost 90 GW globally in 2026, with Europe remaining their largest destination. Battery markets continue to expand, but the week’s evidence points to diverging revenue conditions and greater emphasis on grid services, power quality and large-scale project execution rather than a single hardware-price direction.

1. Solar Modules

Market direction: → Stable

InfoLink Consulting’s assessment for orders delivered and signed from 17 to 23 September found no significant weekly change in module prices. The average non-China TOPCon module price remained at USD 0.114/W, and European prices were described as stable. Polysilicon, wafer and n-type cell averages were also broadly flat, although buyers remained cautious and some low-end negotiations continued.

This is not evidence that every delivered European quote will remain unchanged. Freight, origin, traceability, payment terms, local warehousing, warranty routes and exact module class can all move the landed offer. The practical signal is that buyers should keep benchmarking like-for-like configurations without assuming a broad market fall or a broad increase.

Brand Spotlight — Risen Energy

Risen Energy reported that China’s national intellectual-property authority granted a patent for a heterojunction cell design intended to improve surface passivation and minority-carrier lifetime. The company said its HJT programme has passed 27% cell efficiency and 24.70% module efficiency, while Hyper-ion Pro modules have reached 740 W-plus in mass production. Risen also reported more than 12 GW of this series shipped to over 80 countries and regions.

The development is a technology-roadmap signal rather than proof of European stock. EPCs comparing HJT with TOPCon or BC products should evaluate the exact module offered, including dimensions, weight, temperature behaviour, bifacial assumptions, degradation evidence, delivery route and warranty support. Patent and laboratory milestones matter only when the commercial model and project economics are verified.

Brand Spotlight — First Solar

A new factory-level analysis reported that the United States passed 100 GW of cumulative domestic module production in the second quarter of 2026. First Solar accounted for about 39% of that historical total, reflecting its long-running cadmium-telluride thin-film manufacturing position.

For European professional buyers, the relevance is supply-chain and technology diversification, not an immediate local availability claim. First Solar modules differ materially from conventional crystalline-silicon products, so comparisons should cover energy yield, project design, recycling arrangements, bankability, delivery geography and contractual support. Buyers should verify whether a specific European project can access the required product and service route before treating global production scale as local supply.

2. Inverters

Market direction: → Stable / unclear

No dependable Europe-wide transaction-price benchmark was published during the research window. The strongest evidence instead concerns manufacturing scale and product integration. PV Tech Research forecasts that European-headquartered inverter manufacturers will ship almost 90 GW globally in 2026, around 12 GW more than in 2025. Nearly 32 GW is expected to go to Europe, while European annual solar and storage inverter manufacturing capacity has surpassed 100 GWac.

That capacity does not remove project-level risk. Buyers still need to compare grid-code evidence, cybersecurity, battery compatibility, monitoring, commissioning, warranty terms and local technical support. Public shipment forecasts also do not establish price direction, so the market direction remains stable or unclear.

Brand Spotlight — Power Electronics

PV Tech’s 24 September analysis identified Spain’s Power Electronics, together with SMA Solar Technology, as accounting for the majority of manufacturing capacity and shipments among European-headquartered inverter companies. The finding reinforces the importance of established utility-scale power-conversion suppliers in Europe’s industrial base.

Procurement teams should not interpret the aggregate forecast as a commitment for a specific project or delivery date. For Power Electronics tenders, confirm the exact inverter or PCS platform, manufacturing route, transformer and switchgear scope, grid-forming requirements, controls, commissioning responsibilities, spare-parts strategy and service coverage. Capacity at company level is useful context, but contract-specific lead time and support remain decisive.

Brand Spotlight — Fronius

At Solar & Storage Live in Birmingham from 22 to 24 September, Fronius demonstrated its residential GEN24 platform and commercial Verto, Verto Plus and Tauro inverter ranges. Its live commercial-storage demonstration paired the Verto Plus hybrid inverter with the Reserva Pro battery system, while the product display also covered integrated energy management, backup functions and EV charging.

The procurement relevance is the shift from stand-alone conversion equipment toward coordinated solar, storage and energy-management systems. European installers and C&I buyers should validate compatible battery configurations, backup behaviour, export limitation, monitoring access, commissioning requirements and local warranty handling. Event demonstrations confirm product positioning and regional market activity, but not project availability or commercial terms.

3. Batteries & BESS

Market direction: → Stable / unclear

The weekly evidence does not support a single European BESS hardware-price direction. Revenue signals varied by country in August: Clean Horizon’s analysis reported gains in Spain, France, Italy and Portugal, while Germany and the Baltic markets declined and Poland remained high despite a monthly drop. Separate analysis warned that crowded ancillary-service markets are increasing the importance of multi-market trading, optimizer strategy and degradation-aware dispatch.

At grid level, Fraunhofer IEE estimated that intelligently controlled batteries at 1,313 German rural substations could help integrate around 150 GW of additional PV with about 60 GW of storage, while limiting average curtailment of the added PV to roughly 1%. The study is a technical potential estimate, not verified connection capacity, but it underlines storage’s growing role in network utilization.

Brand Spotlight — Tesla Energy

Giga Storage started construction on the 700 MW/2.8 GWh Green Turtle BESS in Belgium. The four-hour project will use 640 Tesla Megapack 3 units, with Tesla acting as EPC contractor and providing battery supply and long-term maintenance. The project is scheduled for commissioning by the end of March 2028 and is intended to support grid balancing and congestion management.

This is a material European deployment signal, but buyers should still qualify the complete project package: EPC interfaces, grid connection, fire-safety design, performance guarantees, degradation and augmentation assumptions, maintenance obligations and software control. A project of this scale demonstrates delivery capability; it does not establish pricing or availability for other tenders.

Brand Spotlight — LG Energy Solution

LG Energy Solution’s BESS qualified under NVIDIA’s DSX Ready programme for AI-factory infrastructure. The referenced LGES Vertech JF2 AC Link is rated at 5 MW AC and 10 MWh. Qualification focuses on power-conversion behaviour including active and reactive power response, current limiting, ride-through, islanded operation and black-start capability. LG described modular 2.5 MW/5.1 MWh battery blocks and an integrated AC architecture.

The qualification is relevant to fast-growing high-power applications, but it does not replace site engineering or establish European availability. Buyers should verify applicable certifications, cell and PCS provenance, grid studies, transformer and switchgear integration, fire strategy, controls, warranty security and the service organisation available in the project country.

4. Search4Solar Market View

For modules, Week 40 supports disciplined benchmarking rather than directional speculation. European prices were stable, and technology competition continues across HJT, thin-film, TOPCon and BC platforms. Compare usable energy yield, dimensions, logistics, traceability and warranty routes for the exact product instead of relying on headline efficiency or manufacturer scale.

For inverters, Europe’s manufacturing base is expanding, but supplier capacity is not the same as project readiness. Procurement teams should align hardware, grid compliance, cybersecurity, battery interfaces, commissioning and long-term service before award. Integrated solar-and-storage demonstrations make system compatibility increasingly important.

For BESS, the commercial case must be market-specific. Revenue indices moved differently across European countries, while optimizer control and cycling strategy are becoming more important as ancillary-service markets mature. The equipment offer, route to market, grid connection, degradation model, augmentation plan and service contract should be assessed as one bankable system.
