A study conducted by the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) and commissioned by the trade body SolarPower Europe (SPE) concludes that the EU's target of 30 GW of annual solar panel manufacturing is technically and economically feasible. To achieve this goal, the EU and its member states need to "act quickly" and support it with a favorable policy and investment environment. The study highlights two key points in this regard: first, the establishment of an EU-level, output-based support program specifically for the solar manufacturing industry; and second, the effective implementation of the Net-Zero Industry Act (NZIA) policy package across all 27 member states, including, where possible, a "Made in EU" credit. The study notes that without these proposed interventions, the EU solar manufacturing industry will struggle to compete in the global market, "and the sector risks losing its remaining industrial and technological capabilities. Since scaling up production plants typically takes two to three years, the window for creating the necessary conditions for investors to establish plants in the EU by 2030 is limited." Walburga Hemetsberger, CEO of Solar Europe, said: "This new report highlights that with the right policies, Europe can achieve 30 GW of solar manufacturing capacity by 2030, creating thousands of local jobs and building a resilient, innovative solar supply chain that keeps economic value at home. To achieve the 2030 target, the EU and its member states must act quickly. Without intervention, Europe risks losing its remaining industrial and technological capabilities in the solar sector."   The study notes that Europe currently has less than 10 GW of annual manufacturing capacity for wafers, cells, and modules, while China supplies between 81% and 93% of all photovoltaic modules across the entire PV supply chain to Europe.   However, if announced or planned capacity by 2030 is included, this figure is much higher, as shown in the figure below. Even so, the EU still lags behind other regions in module production capacity, particularly the United States, India, and Southeast Asia. The study's analysis is based on three scenarios that meet the resilience criteria of the EU's Net Zero Industry Directive (which came into effect last year and aims to boost domestic renewable energy manufacturing). The first scenario involves establishing a fully vertically integrated supply chain in the EU (from polysilicon to modules, including solar glass and inverters); the second scenario involves sourcing more upstream raw materials—polysilicon, ingots, and wafers—from China, with the remainder produced in the EU; and the final scenario is similar, but with the production center located in Southeast Asia rather than the EU. The European Solar Energy Association estimates that a system produced entirely in the EU would cost approximately €0.128 per watt-peak (Wp) more than a system with mixed product...

European solar buyer confidence plummeted to a record low in July 2025. Affected by the ongoing macroeconomic volatility, buyers are becoming increasingly cautious in their decisions, according to the latest PV Index report released by sun.store.   The report focuses on European solar module prices and market sentiment. The Photovoltaic Purchasing Managers' Index (PV PMI) fell to 65 in July, the lowest reading since the index's inception. This data, based on a survey of 1,321 sun.store users, remains above the industry expansion threshold of 50, but represents a significant drop of 3 points from 68 in June 2025 (the lowest reading for the same period in the previous year and the same as in July 2024). The report also charts this trend and the percentage of respondents expecting product purchases in the coming months. Krzysztof Rejek, sun.store's Vice President of Sales, explained that the market is currently experiencing a seasonal summer slowdown, and many merchants on the platform have activated "holiday mode" to indicate potential supply and communication constraints. However, he also noted that the recent decline in optimism may be more than just seasonal factors. "Low inventory levels and uncertain pricing in the coming weeks complicate the market situation," Rejek said. "We are closely monitoring market developments to see whether activity will pick up significantly in September or whether this cautious sentiment will persist."   This data reflects heightened uncertainty in the global solar supply chain. From the US government's escalating protectionist rhetoric to news of planned capacity cuts by Chinese polysilicon producers, both are impacting the market.   The sun.store report specifically notes that China's polysilicon capacity cuts could push up upstream solar module prices as early as the fourth quarter of this year, subsequently feeding through to European module and inverter prices.   Notably, the decline in the PV PMI index coincides with stabilizing or declining prices for most solar products—a development that should boost confidence among potential buyers. According to sun.store data, the average prices of n-type monofacial and bifacial modules continued to decline between June and July, falling to €0.095/W (US$0.11/W) and €0.099/W (US$0.12/W), respectively. This marked the third consecutive month of decline. The average price of bifacial n-type modules fell below €0.1/W for the first time since March. The report also charts and graphs illustrating module price changes and their significant impact on buyer confidence.   Unlike the module market, European inverter prices have been more stable this year. sun.store noted that prices for the four inverter types it tracks—hybrid inverters below 15kW and above 15kW, and grid-tied inverters below 15kW and above 5kW—have declined month-over-month for two consecutive months. Micro hybrid inverters remain the most expensive type, ...

SUNDTA has announced the successful completion of production and factory testing for a significant order of its advanced high-voltage rack-mounted lithium batteries destined for Cuban customers. The shipment comprises five sets of its 12-module 51.2V 100Ah battery systems and three sets of its nine-module 51.2V 280Ah battery systems, now ready for packaging and transport.   This substantial delivery underscores the growing global demand for SUNDTA's high-voltage lithium battery solutions, recognized for their superior performance and operational advantages. High-voltage systems like those supplied by SUNDTA offer significant benefits over traditional lower-voltage alternatives. Primarily, they enable higher energy efficiency throughout the power conversion chain. By operating at higher voltages, these systems reduce resistive current losses significantly, leading to less energy wasted as heat within the battery packs themselves and throughout the connected power conversion equipment. This inherent efficiency translates directly into more usable energy output, lower operating costs, and enhanced overall system longevity. Furthermore, high-voltage configurations often allow for simplified system design with fewer parallel strings, reducing balance-of-system costs and saving valuable installation space – a crucial factor for both commercial and industrial deployments.   A defining strength of SUNDTA's high-voltage rack-mounted batteries is their exceptional compatibility. Engineered to meet universal communication protocols and electrical specifications, SUNDTA batteries seamlessly integrate and operate stably with a vast majority of energy storage inverters available on the market. This compatibility spans the entire spectrum, from smaller residential and light-commercial units to large-scale, high-power industrial and commercial-grade inverters. Regardless of the application scale, SUNDTA batteries deliver stable, reliable power generation, ensuring systems operate at peak efficiency and high quality.   SUNDTA emphasizes that its batteries are built not just for compatibility, but for robust, high-performance operation. Rigorous quality control, advanced battery management systems (BMS) for safety and longevity, and superior thermal management are integral to their design. This commitment ensures that SUNDTA's solutions provide Cuban partners with dependable, long-term energy storage capable of meeting diverse needs efficiently. The shipment represents a key step in supporting Cuba's energy infrastructure development with advanced, efficient, and highly adaptable lithium battery technology known for its reliable power delivery across all scales of application.
