Taizhou Meilanchun Winery, a key enterprise and precious historical cultural heritage site in Taizhou, completed a major energy upgrade before April 30, 2025 — a 5.1MW rooftop distributed PV station that successfully achieved 10KV high-voltage grid connection, operating in full-feed-in mode. This landmark project was constructed by Solartale and invested by its sister company, injecting new green energy momentum into the traditional liquor industry.
Project Information
- Scale: 5.1MW rooftop distributed PV station
- Grid Connection: 10KV high-voltage grid connection
- Operating Mode: Full-feed-in mode
- Investment: Built by Solartale, invested by sister company
The 10KV high-voltage grid connection system ensures efficient connection between the station and the power grid, maximizing generation benefits. The full-feed-in mode allows clean electricity to be fully transmitted to the public grid, generating stable returns for the winery.
Technical Challenges and Solutions
Diverse Roof Challenge: As a long-established enterprise, the winery's diverse roof structures required customized installation solutions for different factory buildings.
Stringent Safety Requirements: Explosion-proof and fire prevention standards in alcohol production areas far exceeded conventional PV projects. Solartale developed comprehensive safety construction plans.
Cultural Heritage Protection: The team followed the "minimal intervention" principle in all installation techniques, preserving the winery's historical character while introducing green energy.
The station is expected to generate 5.1 million kWh annually and reduce CO₂ emissions by approximately 4,200 tons per year. The successful grid connection marks a new level of technical capability for Solartale in complex industrial environments.
