Solar & Renewable Energy Supplier China for EPCs, Developers & Off-Grid Projects
The Buyer Challenge
Solar Looks Simple Until the Wrong Module Bin Arrives
Modules and inverters may look like commodities, but bankability, cell grade, grid code and warranty paths are project-critical. The wrong choice can reduce output or delay commissioning.
Clean-looking panels can hide micro-cracks that only appear during EL imaging.
A string inverter may fail G99, AS 4777 or VDE approval and block utility connection.
Reject cells sold as Grade-A create short cycle life and BMS problems.
String voltage and MPPT windows do not match the selected panel configuration.
Rated modules measure below stated wattage and reduce system yield from day one.
Weak pallet design and poor edge protection cause module damage before unloading.
How JEES Works
Solar Sourcing Built Around Bankability and Grid Code
We treat each system as a long-term financial asset. Bankability, certifications, warranty path and grid code are confirmed before the purchase order opens.
Read System BOM
Layout, string sizing, grid code, battery autonomy and EV scope are mapped per project.
Shortlist Bankable Makers
Tier-1 module makers, inverter brands and Grade-A cell suppliers are compared per market.
Verify Grid Code & EL
The inverter grid-code certificate is confirmed and modules are EL-imaged and flash-tested.
Pack DG, Load & Ship
UN 38.3 battery packing, module pallets, supervised loading, certificates and MSDS are coordinated.

Custom Specifications
Configured Around Your Site Layout and Grid Code
String voltage windows, MPPT count, grid-code version, battery limits and mounting loads are committed before production so commissioning is not left to assumptions.

Specification Checklist
Factory Coordination
Module, Inverter, Battery and Mounting Matched Before the PO Opens
PV is a system, not a parts list. Module strings, MPPT windows, grid code, battery voltage and mount type are checked together before production.
Quality Inspection
EL Imaging, Flash and Grid Code Verified Before Pallet Wrap
Micro-cracks and grid-code mismatches can quietly damage project returns. We verify the modules, inverter documentation, battery cell references and packing before release.
Pre-Shipment Inspection Checklist
Export & Shipping
From Module Pallet to Your Project Site
Solar shipments combine fragile modules, dangerous-goods batteries and structural mounting. Each part is packed and documented under one coordinated shipping plan.
Pack by Discipline
Modules on plywood pallets with edge protection, batteries in UN 38.3 DG packing and mounting banded.
Prepare Documents
IEC and grid-code certificates, MSDS, UN 38.3 reports, bankability letters and certificate of origin.
Load & Ship
FOB, CIF or CFR shipping with DG handling, supervised loading and seal photos.
