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.  

SUNDTA announces a significant milestone with the completion, rigorous factory testing, packaging, and imminent shipment of its advanced energy storage solution to Ukrainian customers. The shipment comprises the robust SUNDTA 30kWh + 10kWh lithium battery system and the high-performance 30KW + 12KW Deye hybrid energy storage inverter. This deployment underscores the growing confidence Ukrainian partners place in SUNDTA's technology for enhancing energy resilience.   Once operational in Ukraine, this integrated system possesses significant generation potential. Leveraging the 30KW solar input capacity, and factoring in Ukraine's average annual solar insolation (approximately 1,100 full-sun hours per year), the system is theoretically capable of generating up to 33,000 kWh of clean electricity annually (30 kW * 1,100 hours). The SUNDTA lithium battery system is crucial for maximizing the utility of this generated power. Its high round-trip efficiency (typically exceeding 95%) ensures minimal energy loss during charging and discharging cycles, meaning more captured sunlight is available for use. This efficiency translates directly into greater energy independence and cost savings for the end-user.   The SUNDTA battery excels not only in efficient energy storage but also in its exceptional versatility. A key competitive advantage is its seamless compatibility with a wide array of energy storage inverters available on the market. While expertly paired here with the Deye inverter, SUNDTA batteries are engineered to integrate reliably with most major brands, offering customers and installers significant flexibility and avoiding vendor lock-in. This broad compatibility simplifies system design, reduces installation complexity, and provides Ukrainian partners with adaptable solutions tailored to diverse project requirements.   The shipment of this pre-tested and integrated solution directly reflects the trust Ukrainian customers place in SUNDTA's product quality, reliability, and technical support. The lithium iron phosphate (LiFePO4) chemistry used in SUNDTA batteries offers inherent safety, long cycle life (often exceeding 6,000 cycles), and stable performance even in demanding conditions – vital attributes for ensuring uninterrupted power in Ukraine's challenging environment. By enabling effective storage of solar energy, this SUNDTA system provides critical backup power during outages, allows for significant consumption of self-generated electricity (maximizing self-sufficiency), and actively contributes to stabilizing the local grid. This delivery marks a crucial step in empowering Ukrainian communities and businesses with resilient, efficient, and adaptable energy storage technology.
