Our Facilities
Driven by operational excellence, our industrial footprint covers a total built-up area of approximately 23,000 square meters, strategically localized to serve global energy markets.
We operate two large-scale manufacturing campuses in Shandong, one of which serves as our premier technical training center and R&D experimental laboratory. Our manufacturing capacity is further strengthened by a cutting-edge production base in Beijing, while our international marketing and export division operates from Shanghai, ensuring seamless cross-border communication, rapid-response services, and end-to-end supply chain reliability for our worldwide clients.
ASTA Type Test Certification
Our medium voltage switchgear products have been type tested and certified by Intertek ASTA in accordance with IEC 62271-200 standards, covering both 24kV and 36kV load break switch (LBS) and vacuum circuit breaker (VCB) configurations, ensuring international compliance, safety, and reliability.
FA&Q
- Not necessarily. The ideal system size depends on a balanced evaluation of three core factors:
- Energy Consumption Habits:We calculate this based on your high-power household appliances, such as central air conditioning, underfloor heating, and swimming pool pumps.
- Roof Conditions & Area:Available space dictates capacity. As a benchmark, pitched roofs yield an installation capacity of approximately 100 W/m², while flat roofs yield around 70 W/m².
- Grid Connection Policies:The system capacity must comply with your local utility provider's maximum approval limits and net metering regulations.
- This is the most efficient operational mode for modern residential solar, maximizing your ROI through two mechanisms:
- Self-Consumption:Solar energy generated during the day is prioritized to power your home in real time, directly slashing your reliance on expensive grid electricity.
- Surplus to Grid:Any excess electricity your home doesn't use is automatically fed back into the local utility grid, allowing you to earn extra revenues through feed-in tariffs (FiT).
- Smart Monitoring:Our system supports intelligent power scheduling and real-time data tracking. You can monitor daily power generation, household consumption, and financial yields effortlessly via a dedicated mobile APP.
- To ensure long-term value, safety, and visual appeal, you should prioritize the following four criteria:
- High Efficiency:Premium cell architecture ensures higher conversion rates, guaranteeing maximum electricity generation per square meter of roof space.
- Architectural Aesthetics:Look for sleek, low-profile designs (such as premium all-black solar modules) that seamlessly blend with modern villa aesthetics without compromising curb appeal.
- Certified Safety & Reliability:Ensure the modules have passed rigorous international third-party testing (such as TÜV, CE, UL) and come with a comprehensive long-term performance warranty.
- High Adaptability:The mounting structures and panel layouts must be custom-tailored to match your specific roof material, tilt angle, and local wind/snow load requirements.
- A:Solar panels require sunlight to generate electricity and do not produce power at night. To achieve true energy independence, we highly recommend integrating a Home Energy Storage System (ESS). The battery stores excess solar energy captured during the day and discharges it at night or during unexpected grid blackouts, ensuring your villa enjoys 24/7 uninterrupted green power.
- Our smart residential systems are engineered for longevity. Solar modules typically come with a 25-to-30-year linear performance warranty, while smart hybrid inverters and lithium iron phosphate (LiFePO4) batteries are designed to last 10 to 15 years. The system requires minimal maintenance—mostly occasional cleaning of the panel surfaces to remove dust and remote OTA (Over-the-Air) firmware updates via our app.
- Depending on your local utility electricity rates, solar radiation levels, and regional government incentives/subsidies, the typical payback period ranges from 4 to 7 years. Once the initial investment is recovered, the system will provide free, clean electricity for the remainder of its 25+ year operational lifespan, significantly increasing your property value.
