Sinograin Songyuan 16kW Micro-inverter PV Station
Grain Depot Roof · Safe & Efficient · Green Storage · Smart O&M
Project Overview
- Project Location:Sinograin Depot Roof, Songyuan, Jilin
- Installed Capacity:16kWp
- System Solution:All Micro-inverters + High-efficiency Monocrystalline Modules
- Operation Mode：Self-consumption (office, ventilation, monitoring)
- Commissioning Date:2025
- Avg. Annual Generation:~19,000 kWh
Project Background & Requirements
Sinograin Songyuan Depot, a national grain reserve base, has stable power loads (monitoring, ventilation, temperature control, office) with extremely high demands for power safety, fire/explosion prevention, and long-term reliability...
Project adoptsmicro-inverter solution，core solutions：
- grain depotStrict fire/explosion safety requirements;，no risk of high-voltage DC arcing allowed.
- Scattered roofs with partial shading; traditional string solutions suffer high power loss.
- Northeastsevere winter cold，summer heat, and large day-night temperature swings demand high equipment reliability..
- Grain depotrequires low-temperature storage;PV panels provide insulation and cooling (2–3°C reduction).
- .Unattended operation, smart monitoring, precise fault location —reducing O&M pressure.
Core Solution (Micro-inverter Advantages)
Independent MPPT per module eliminates shading/mismatch 10–15% higher generation
.
No high-voltage arcing, no shock risk
Meets high fire/explosion-proof standards of grain depots.
Reliable from -40°C to +65°C
Suitable for NE China's extreme cold and heat.
Remote real-time monitoring & precise fault location
Unattended, minimal O&M
Project Outcomes & Value
- Generation Revenue:~19,000 kWh annual generation, ~15,000 RMB saved on electricity.
- Safety Value:Zero high voltage, zero fire risk — passed depot safety inspection.
- Grain Storage EfficiencyPV roof insulation lowers depot temperature by 2–3°C, enabling low-temperature grain storage.
- Emission Reduction:~18.8 t CO₂ reduction/year, equivalent to planting 1,030 trees.
- O&M Cost:60%+ lower O&M cost vs. traditional solutions, with a 25-year lifespan.
