The Solar Refrigeration Solution provided by FOSSIL Factory can be applied to various scenarios ranging from kilowatts to megawatts. It is widely used in cold chain storage, biopharmaceuticals, food processing, commercial retail and other fields, helping customers reduce their reliance on the power grid, significantly lower operating costs, and accelerate the achievement of carbon neutrality goals.
The Solar Refrigeration Solution consists of four core modules, seamlessly coordinated through an intelligent Energy Management System (EMS):
PV Generation Subsystem: High-efficiency monocrystalline silicon modules support rooftop, ground, and carport installations, converting sunlight into DC power to supply clean energy for the entire refrigeration system.
Intelligent Energy Storage Subsystem: LFP battery packs paired with a BMS battery management system store excess energy during sunny hours and continue powering cooling loads at night or on cloudy days, ensuring 24/7 uninterrupted operation.
Refrigeration Terminal Subsystem: Includes cold room units, commercial freezers, medical refrigerators, and other terminal types, utilizing DC variable-frequency and natural refrigerant technology for low energy consumption and high-precision temperature control.
Energy Management & Monitoring Platform: Real-time collection of generation, storage, consumption, temperature, and humidity data across the full chain. Remote monitoring via mobile app and web, with fault warnings and O&M scheduling at your fingertips.
Compared with traditional grid-powered refrigeration, annual electricity expenses can be reduced by 60%~90%. Combined with energy storage peak-valley arbitrage, some scenarios see payback periods as short as 4~6 years, with outstanding long-term operating cost advantages.
Dual-power automatic switching mechanism with grid and solar 互为 backup, delivering zero-perception power interruption. Critical temperature data is stored both locally and in the cloud, meeting GSP, GDP, and other pharmaceutical cold chain compliance requirements.
Modular design supports on-demand configuration, customizable from single-store freezers to 10,000-ton cold storage. PV panels and storage units can be added anytime as business expands, with smooth system upgrades and no downtime.
Full-lifecycle carbon footprint is reduced by over 75% compared with traditional solutions, helping enterprises obtain green certifications and improve ESG ratings — gaining an edge in government procurement and supply chain bidding.
Pharmaceutical & Biotechnology: Precise temperature control at 2~8°C refrigeration and -23°C freezing for vaccines, blood products, and biological reagents, meeting strict regulatory requirements for temperature/humidity recording and traceability.
Food Cold Chain Logistics: Covers the full chain from pre-cooling at origin, transit warehousing, to urban distribution — preserving quality and freshness of fresh produce, meat, and seafood, reducing spoilage rates by over 30%.
Supermarkets & Retail Chains: Integrated solar cold chain solutions for convenience stores, supermarkets, and fresh food shops, lowering store operating costs and enhancing green brand image.
Agriculture & Rural Revitalization: Cold chain infrastructure for field pre-cooling rooms, cooperative storage centers, and township farmers' markets, helping agricultural products stay fresh, increase value, and extend sales cycles.
Industrial & Specialized Fields: Customized solutions for chemical raw material low-temperature storage, electronic component constant temperature/humidity, laboratory environment control, and other professional scenarios.
Step 1: Demand Survey & Scheme Design Professional engineering teams conduct on-site assessments, delivering customized design proposals and ROI analysis reports based on customer load characteristics, installation conditions, and budget ranges.
Step 2: System Integration & Construction In-house construction teams execute strictly in accordance with national standards. EPC turnkey delivery ensures engineering quality and construction progress.
Step 3: Commissioning & Staff Training After system integration testing and performance verification, operation training and emergency drills are provided for customer O&M teams, ensuring efficient and stable equipment operation.
Step 4: O&M Support & Continuous Optimization 7×24 remote monitoring and annual inspection services are provided. System strategies are continuously optimized based on operational data to maximize energy efficiency and return on investment.
To date, we have deployed over 500 solar refrigeration projects across 31 provinces, municipalities, and autonomous regions in China, with cumulative installed capacity exceeding 200MW. Each year, we help customers reduce carbon emissions by approximately 260,000 tons — equivalent to the carbon sequestration of 14 million trees.
Our clients include Fortune 500 companies, tertiary hospitals, retail chain giants, and national-level agricultural industrial parks. The longest-running project has been operating stably for over 8 years, with a system availability rate of 99.7%.
