A Small Export Team With a Factory-Grade Supply Line
We don’t pretend to be a giant manufacturer. Yoyang is a focused export team that sells one thing — standard off-grid solar power systems for cameras and routers — backed by a production line we’ve worked with for years.
Honest by Design
We are not the factory. We’re a small, specialist export team in Shenzhen that sells solar power supply systems from a partner production line. We say this openly because it matters: what you get from us is a real product with honest specs, consistent quality and a person who actually answers your email.
That structure is exactly why our customers stay: small enough to answer in hours, connected enough to deliver factory-direct quality and pricing. No layers of salespeople, no inflated promises — just the models we stock, checked before they ship.
- One product line, deeply understood — we live and breathe off-grid camera power
- Every unit visually checked before packing
- You talk to the same person from quote to delivery
What We Do — and What We Don’t
Clear boundaries keep both sides efficient. Read this before you write to us — it saves a round-trip.

- No “we’re a 50-year-old factory” stories — we’re not
What “Checked Before Shipment” Means
Panel Output Verification
Each panel is verified against its rated wattage. We reject cells below A-grade standard before assembly.
Battery Cycle Integrity
18650 ternary lithium cells are charge/discharge tested; packs are checked for balance and capacity before they leave the line.
Visual & Functional Check
Before packing, every unit gets a visual inspection plus a controller power-on test — no dead-on-arrival surprises.
Careful Packing for Freight
Systems are packed for sea/land transport with battery terminals protected. Carton details confirmed on your PI.
