Energy Storage Systems for Solar Integration Projects

What is an Energy Storage System for Solar Integration?

An Energy Storage System (ESS) for solar integration is a battery-based solution designed to store surplus solar energy during the day and discharge it when sunlight is insufficient—such as at night or during cloudy weather. By pairing solar PV with a reliable ESS, users can maximize energy self-consumption, enhance energy reliability, and reduce dependence on the grid.

ESS plays a critical role in balancing supply and demand in solar projects, improving ROI, and enabling true energy independence for both residential and commercial users.

Types of ESS for Solar Integration

Residential Solar ESS

5kWh–80kWh capacity

Stackable, wall-mounted, or rack-based options
✅ Ideal for solar-powered homes and villas

Commercial & Industrial ESS

100kWh–500kWh+ capacity

Designed for offices, factories, farms, or logistics centers
✅ Supports net metering, TOU arbitrage, and backup

Utility-Scale Containerized ESS

1MWh–5MWh+ modular containers
✅ Integrates with solar farms or microgrids

Hybrid PV + ESS Systems

Combines solar inverter, lithium battery, and EMS in one system
✅ Simplifies installation and operation

Dagong ESS offers a full range of solar-compatible energy storage solutions with both air-cooled and liquid-cooled designs.

Community Microgrids or Utility PV Farms

Price of Energy Storage for Solar Integration

Pricing is based on:

System size (100kWh to 5MWh+)

Cooling type (air-cooled vs. liquid-cooled)

Integration needs (PV, EMS, grid connection)

Air-cooled cabinets (100kWh–241kWh) are more cost-effective for mid-scale peak shaving. Liquid-cooled container systems (215kWh–5MWh) suit larger factories or EV infrastructure.

Prices are usually quoted as EXW, FOB, or CIF, depending on logistics and project location.

How Long Does a Solar ESS Last?

High-quality LFP-based ESS typically last:

8,000+ cycles at 70% SOH

15+ years of daily operation

Minimal degradation when paired with smart EMS and temperature management
