172.5KW Waterproof Solar Carport Mounting System in Japan

YIJIA SOLAR’s 172.5KW Waterproof Solar Carport System redefines urban renewable energy integration in Japan, merging cutting edge engineering with climate resilience to address the nation’s dual challenges of limited space and extreme weather. This project exemplifies YIJIA SOLAR’s commitment to delivering multifunctional solar infrastructure that harmonizes with Japan’s architectural and environmental priorities.  

 Project Overview  

Deployed across commercial complexes and public facilities, the YIJIA SOLAR designed carport transforms parking zones into high yield solar hubs, generating 215,000+ kWh annually—enough to power 60 Japanese households. The system’s waterproof design and typhoon resistant structure ensure uninterrupted operation during Japan’s rainy seasons and typhoon threats, offsetting 162 metric tons of CO₂ yearly (equivalent to planting 3,900 cedar trees).  

 Technical Innovations  

1. Storm Ready Waterproofing:  

    YIJIA SOLAR’s patented sloped design (5°–10°) with integrated drainage channels prevents water pooling, certified for 250 mm/hour rainfall.  

    Marine grade aluminum alloy (JIS H 4000) and anti corrosion bolts withstand 150 km/h winds and coastal salt exposure.  

2. Seamless Urban Integration:  

    Modular components allow rapid assembly without disrupting parking operations, ideal for Tokyo’s space constrained districts.  

    Adjustable tilt angles (15°–25°) optimize energy capture across seasons, achieving 1,250 kWh/KW/year efficiency.  

 Strategic Benefits  

 Economic ROI: Generates ¥28M annual savings with 4.8year payback under Japan’s FIT program (¥16/kWh) and Green Investment Tax Credits.  

 Space Efficiency: Produces 124 kWh/m²/year—30% higher than rooftop systems—by dual purposing parking zones.  

 Disaster Resilience: Integrated 500 kWh battery storage provides emergency power during earthquakes or grid outages.  

 Environmental Leadership  

By displacing 65,000 liters of diesel annually, this YIJIA SOLAR powered initiative supports Japan’s 2030 GHG reduction targets. The carport’s sleek, low profile design (2.2m height) complies with strict urban aesthetics codes, proving sustainability and style can coexist.  

YIJIA SOLAR continues to pioneer solar solutions that empower Japan’s energy transition, demonstrating how innovation and environmental stewardship can drive a brighter, greener future.
