Turnkey Solar
EPC Solutions
From system design to commissioning, JUSTSOLAR delivers complete solar projects. As a manufacturer, we control the entire supply chain — modules, inverters, storage, and mounting — all from our own production lines.
Our EPC Services
Full project lifecycle support — from initial design to long-term operation.
System Design
Complete electrical and structural design. PVsyst simulation, string sizing, single-line diagram, BOS specification, and structural loading calculations.
Equipment Supply
All components from one manufacturer: JUSTSOLAR TOPCon/HJT modules, inverters, LiFePO4 batteries, aluminum mounting structures, cables, and BOS.
Logistics Management
End-to-end shipping coordination. Container optimization, ocean freight booking, All Risk cargo insurance, customs documentation, and port delivery.
Installation Support
Remote technical support during installation. Wiring diagrams, torque specs, grounding guidance, inverter commissioning, and monitoring setup.
Commissioning & Testing
IV curve testing, insulation resistance measurement, thermal imaging, and performance verification. Commissioning reports for grid connection approval.
After-Sales & O&M
25-year module warranty support. Remote monitoring, performance analytics, cleaning recommendations, and spare parts supply for long-term operation.
Project Types

Agrivoltaics
200kW - 20MWElevated mounting for dual land use — solar energy generation above, crop cultivation below. Irrigation and cold storage integration.
Recommended: TOPCon 640W (elevated mount)
The Manufacturer Advantage
Unlike pure EPC contractors who source equipment from multiple suppliers, JUSTSOLAR manufactures the core components. This means better pricing, unified warranty, and faster delivery.
