—Award from ImpiantiNews, a Leading Italian Media Outlet
On July 14, 2026, Milan time, the inaugural ImpiantiNews Awards 2026 ceremony concluded successfully at the Palazzo della Cultura in Milan, Italy.Thanks to the flagship solar-storage integration project at Tenerife Football Club in Spain’s Second Division, SAJ CHS2 hybrid solar-storage solution successfully won the Best Case History Award (Renewable Energy Category) at this year’s event!
The ImpiantiNews Awards were initiated by the renowned Italian industry media outlet ImpiantiNews.it and co-hosted by several top European engineering journals, including *Elettro*, *GT*, and *RCI*. This marks the inaugural edition of this major awards program targeting the HVAC, power automation, renewable energy, and building security sectors.
While most brands in the industry are still in the stages of new product announcements and pilot demonstrations, SAJ has long achieved the stable deployment of commercial PV-storage projects, long-term trouble-free operation, and comprehensive leadership in actual measurement data.Its rock-solid operational performance over the past two years—with zero failures and zero customer complaints—has earned high recognition from both authoritative European industry media and professional judges, firmly demonstrating the top-tier standards of Chinese photovoltaic-storage brands!

This year’s event attracted over 150 industry guests to Milan, with numerous well-known companies competing for major awards on the same stage.SAJ Regional Manager for Italy was on hand in Milan to accept the award. This honor is by no means merely a conceptual product award; rather, it represents the European market’s ultimate recognition of Sanjing Electric’s implementation capabilities, long-term stability, and ability to deliver tangible returns. It fully demonstrates that the CHS2 solar-storage solution is highly suited for commercial and industrial applications in Southern European countries such as Spain and Italy, and is ready for large-scale replication and deployment!
The owner of this award-winning project is Tenerife Football Club, a long-standing powerhouse in Spain’s professional Second Division. As a professional sports venue with high local visibility and influence,the venue has high electrical loads, frequent equipment operation, and stringent requirements for power supply stability. It demands extremely high standards for the reliability, safety, and cost-effectiveness of the photovoltaic-storage system, making it a widely recognized high-difficulty commercial and industrial application scenario within the industry.
The load characteristics of Tenerife Football Club’s stadium are quite typical: PV power generation is concentrated during the day; peak electricity consumption occurs between 6:00 PM and 10:00 PM, with lighting and air conditioning loads rising significantly during the evening;Additionally, the local grid enforces a “zero net metering” policy, prohibiting the feeding of surplus solar power into the public grid, which easily leads to a waste of solar resources; In the event of a sudden power outage at the venue, daily training and match schedules are severely disrupted.
The project deployed three sets of SAJ CHS2 hybrid grid-connected and off-grid photovoltaic-storage systems (50 kW/100 kWh)
✅ Total energy storage capacity: 300 kWh; rated power: 150 kW
✅supporting PV installed capacity ：251 kWp
✅ Official Commissioning: September 10, 2024 ; the system has operated stably for nearly two years to date, with zero faults and zero customer complaints throughout
SAJ’s project has undergone nearly two years of round-the-clock, high-frequency real-world testing, with all metrics comprehensively outperforming industry standards and exceeding simulation expectations:
1. Power generation efficiency exceeded expectations, maximizing resource utilization
In its first year, the project generated a cumulative total of 334 MWh, with an equivalent utilization of 1,330 hours; actual power generation exceeded authoritative PV-Syst simulation data by 7.7%. Leveraging CHS2 intelligent energy storage dispatch, the project perfectly resolved the challenge of curtailed solar power under zero-feed-in policies, maximizing the consumption of clean solar power.
2. Extremely stable energy storage operation with high efficiency throughout the entire lifecycle
The system completes an average of one full charge-discharge cycle per day, consistently maintaining a 90% depth of discharge; total discharge in the first year reached 89.71 MWh, precisely achieving the energy time-shifting principle of “storing solar energy during the day and discharging during evening peak hours,” perfectly aligning with the club’s electricity consumption patterns.
3. Greater Peace of Mind Regarding Power Supply
In the event of an unexpected power outage, the energy storage system seamlessly switches to off-grid mode, providing continuous power to critical loads such as stadium lighting and charging stations. This ensures that sporting events and basic power needs remain unaffected, delivering stable and reliable energy supply.
4. High Returns Without Subsidies: Tangible Economic Benefits
Through self-generation and self-consumption, combined with peak-off-peak electricity price arbitrage, the system achieves average annual electricity cost savings of 15,250 euros. Without any government subsidies, the energy storage system has a static payback period of less than five years, setting a benchmark for ultra-high returns in energy conservation and consumption reduction for commercial sports venues and industrial and commercial facilities.
5. Minimal O&M, Zero Failures and Zero Cost Pressure Throughout the Entire Lifecycle
No major equipment failures or customer complaints throughout the entire operation; annual routine maintenance takes less than 8 hours, with annual maintenance costs below 250 euros. Leveraging the elekeeper Smart Energy Management Platform for remote real-time monitoring and intelligent prediction of potential issues, the system achieves unattended, long-term, and stable operation.
Actual test data indicates there is still room to expand the existing energy storage capacity. Increasing the storage scale will allow for the absorption of more surplus solar power, further amplifying energy-saving benefits and providing a reference for capacity expansion in similar venue projects.
Unlike industry products that rely solely on specifications and conceptual marketing, SAJ CHS2 is a mature solution that has undergone nearly two years of high-frequency, real-world validation at the Tenerife Football Club. Its five core advantages are precisely tailored to high-end commercial and industrial scenarios worldwide:
✅ Integrated design for rapid installation: The highly integrated container solution features a compact footprint and quick deployment, making it suitable for diverse site conditions such as sports venues, commercial buildings, and factories.
✅ Strict safety certification standards ensure stable and reliable performance under high-load, high-frequency continuous operation scenarios, meeting European safety requirements for commercial buildings.
✅ elekeeper (Smart Energy Management Platform) provides real-time monitoring of load, power generation, and energy storage status, intelligently schedules power distribution, and offers simple, intuitive operation and maintenance.
✅ Grid-out backup power capability: In the event of a grid outage, it ensures continuous power supply to critical loads, safeguarding business continuity.
✅ High-level coordination between PV, storage, and the grid, perfectly supporting the integrated operation of solar, energy storage, and the local grid, and easily meeting grid regulations in various countries, such as Spain’s “zero feed-in” policy.
Currently, Southern Europe is accelerating its journey toward energy independence and carbon neutrality, driving explosive growth in demand for photovoltaic and energy storage solutions in the commercial and industrial sectors. Winning the ImpiantiNews Best Case Study Award represents yet another significant endorsement from the European market of SAJ product maturity, project implementation capabilities, and long-term operational stability.
While competitors are still iterating on products and refining pilot projects, SAJ has already achieved comprehensive leadership through large-scale project deployment, long-term stable operation, recognition with authoritative awards, and verifiable revenue data.
Moving forward, SAJ will continue to deepen its presence in core Southern European markets such as Spain and Italy. With its mature and stable CHS2 commercial and industrial solar-plus-storage solution, the company will provide one-stop green energy solutions for more high-end commercial complexes, sports venues, and industrial enterprises, continuing to support Europe’s energy transition!
