One System. Every Scale.
Yiwei's solar + storage solutions integrate photovoltaic generation with battery energy storage across every scale — from residential rooftops to industrial parks and utility ground-mount plants. By pairing PV with storage, you capture more of the solar you generate and use it when it matters most.
Our integrated approach combines high-efficiency PV modules, LFP battery systems, hybrid or central PCS, and a unified EMS platform. The system automatically maximizes self-consumption, reduces curtailment, and provides time-shifting and backup power — all managed through a single monitoring and control interface.
Whether you are installing a rooftop system on a factory, a solar-plus-storage plant for an industrial park, or a large ground-mount facility, Yiwei delivers optimized designs that increase solar utilization, reduce grid dependency, and improve project economics across global markets.

Get More from Your Solar
An integrated solar + storage system that maximizes the value of every kilowatt-hour you generate.
Maximize Self-Consumption
Store excess solar generation during midday and discharge it in the evening when load is high and solar output drops, raising self-consumption from 30% to 70–90%.
Reduce Curtailment
Absorb surplus solar that would otherwise be curtailed due to grid constraints, increasing overall plant yield and improving project revenue.
Time-Shift Energy
Shift solar generation from low-value midday hours to high-value evening peak periods, capturing time-of-use arbitrage and demand charge savings.
Scalable Across Scenarios
From kilowatt-scale rooftops to megawatt-scale ground mounts, the same integrated architecture adapts to your site, load profile, and grid conditions.

Integrated for Optimal Performance
Every solar + storage system is designed as a single coordinated platform. PV, battery, PCS, and EMS work together seamlessly — no third-party integration gaps, no compatibility issues.
- High-efficiency monocrystalline PV modules, 400–700 W
- LFP battery systems, 100 kWh – 100 MWh scalable
- Hybrid inverter or DC-coupled / AC-coupled architecture
- Unified EMS with self-consumption, TOU, and backup modes
Built for Every Solar Scene
From rooftop to ground-mount, our solar + storage solutions adapt to your site, scale, and operational requirements.
Rooftop Systems
Commercial and industrial rooftop PV paired with behind-the-meter storage maximizes self-consumption, reduces demand charges, and provides backup power.
Industrial Parks
Distributed rooftop and carport PV across multiple buildings, aggregated with central storage and EMS, optimizes park-wide energy use and costs.
Ground-Mount Plants
Utility-scale solar farms co-located with storage provide firm capacity, ramp rate control, and energy shifting for wholesale market participation.
Commercial Buildings
Office buildings, retail centers, and hotels use rooftop solar + storage to reduce energy costs, meet sustainability targets, and ensure power resilience.
