Amid rising electricity costs and occasional power rationing policies, ensuring stable power for production and operations while controlling energy expenses has become a major challenge for many business owners. The traditional model of grid power plus diesel backup is struggling to meet the modern enterprise's need for efficient, environmentally friendly, and economical energy consumption. The integrated PV-Storage-Diesel solution has emerged as a new trend in commercial and industrial energy management.
What is an Integrated PV-Storage-Diesel System?
A PV-Storage-Diesel system is an intelligent microgrid system that integrates PV generation, battery storage, and a diesel generator. It uses a smart control system to coordinate these three energy sources for optimal utilization:
-
PV Modules: Generate electricity using solar energy from factory rooftops and other spaces, reducing grid consumption during peak daytime hours.
-
Storage System: Charges during off-peak, low-tariff hours and discharges during peak, high-tariff hours, capitalizing on peak-valley price differences.
-
Diesel Generator: Serves as a backup power source, automatically starting during grid outages to ensure critical equipment stays online.
Why Do Commercial & Industrial Businesses Need a PV-Storage-Diesel System?
1. Significantly Reduce Electricity Costs
Through "PV self-consumption" and "storage arbitrage," enterprises can drastically cut electricity expenses:
-
PV generation replaces expensive grid power, directly lowering daytime electricity costs.
-
The storage system charges during low-tariff periods and discharges during high-tariff periods, earning from the price spread.
-
Reduces diesel generator runtime, lowering fuel costs.
2. Ensure Production Power Reliability
-
During a grid outage, the system switches to storage power in milliseconds, preventing downtime for critical equipment.
-
During prolonged outages, the diesel generator automatically starts, working with the storage system to ensure production.
-
Intelligent load management prioritizes power supply for critical equipment.
3. Enhance Green Corporate Image
-
Reduces carbon emissions, fulfilling social responsibility.
-
Aligns with national dual-carbon policy goals.
-
Boosts environmental image and enhances market competitiveness.
Wide Range of Applicable Scenarios
PV-Storage-Diesel systems are particularly suitable for:
-
Manufacturing plants: High electricity costs, high requirements for production continuity.
-
Logistics warehouses: Large rooftops suitable for PV installation; high energy demand for facilities like cold storage.
-
Data centers: Extremely high requirements for power supply reliability.
-
Commercial complexes: High electricity tariffs, significant load fluctuations.
-
Businesses in remote areas: Unstable grid, difficult power guarantee.
Investment Return Analysis
For a typical medium-sized manufacturing enterprise investing in a PV-Storage-Diesel system:
-
Initial Investment: ¥2-5 million (depending on system scale)
-
Annual Electricity Savings: ¥500,000 - ¥1.2 million
-
Payback Period: 4-6 years
-
System Lifespan: 20+ years (PV modules) / ~10 years (Storage batteries)
Furthermore, many regions offer incentives like PV generation subsidies and energy storage project subsidies, which can further shorten the payback period.
