Jiangxi, China Solar & Storage Project: Cost Savings & Green Energy
Project Purpose The project involves installing solar panels and energy storage systems on rooftops and open spaces in an industrial park, with the goal of improving energy efficiency, reducing electricity costs, and supporting renewable energy policies.
Basic parameters 1 MW/2.15 MWh
Project Overview The rooftop and open-ground solar energy storage project in Jiangxi Industrial Park, China, achieves an annual power generation of 3 million kWh through a 2.8MW photovoltaic and 1MW/2.15MWh energy storage system, significantly reducing electricity costs and promoting the transition to clean energy.

What This Project Is All About
In Jiangxi, China, an industrial park is making smart use of its empty rooftops and unused land by installing solar panels and adding a storage system. This combination not only helps the park use energy more efficiently, but also reduces electricity costs and aligns with the country’s renewable energy policies, promoting the adoption of clean power.
The Nitty-Gritty Details
1. How It’s Used
The project utilizes the rooftops of 12 factory buildings and some additional land to install solar panels. The electricity generated is first used by businesses in the park, and any excess is sent to the main power grid. This helps reduce electricity costs and encourages greater use of green energy.
2. What’s in the System
Solar Part:
- Rooftop area: 38,518 square meters
- Number of solar panels: 4,745 (each 590 Wp, monocrystalline)
- Total power: 2.79955 MWp
Storage Part:
- Storage capacity: 1 MW/2.15 MWh (provides stable power and acts as a backup)

3. Key Gear
- Solar panels and the frames that hold them up
- String inverters (change the power from panels to a usable kind)
- Wiring, grounding setups, and lines that collect the power
- Cabinets to connect to the main grid
- Machines that clean the solar panels automatically
- Safety barriers
- Waterproofing fixes for rooftops and bases for the storage gear
Why This Project Stands Out
1. Balances Power Use and Goes It Alone
The 1 MW/2.15 MWh storage system balances energy usage during peak times, enabling the park to rely more on its own power and reduce dependence on the grid.
2. Makes Rooftops Worth More
Using empty roofs and ground means the land is being put to work, making it more valuable.

3. Saves on Electricity
The system generates around 3 million kWh of electricity annually, significantly reducing the park’s electricity expenses.
4. Good for the Planet
It helps the industrial park switch to greener ways, cuts down on carbon emissions, and fits with the country’s energy rules.
5. Easy to Take Care Of
With automatic cleaners and safety barriers, there’s less work to do to keep it running, so long-term costs stay low.
Wrapping It Up
This Jiangxi project combines solar power and storage to improve energy efficiency. It cuts costs and promotes the use of green energy, benefiting both the park’s bottom line and the environment.
