What Is an Epoxy-Resin Solar Panel? Small PV Encapsulated with Resin
Keywords: epoxy-resin solar panel, resin-encapsulated solar panel, small solar panel encapsulation ｜ Target product: Epoxy-resin (resin-encapsulated) solar panel ｜ Suggested placement: Blog (EN site)
Search intent: The “shiny” small panels in night lights, toys and solar garden lights are epoxy-resin solar panels. How are they made? What are they good for?
Quick Answer
Epoxy-resin solar panels are small panels made by placing cells into a mold and pouring liquid epoxy resin to encapsulate them: low cost, fast production, crystal-clear shiny surface — widely used in garden lights, night lights, toys, calculators and chargers. Best for miniaturized, short-lifespan, light indoor/outdoor scenarios; for high power / long-term outdoor, use glass or ETFE.
How Resin Encapsulation Is Made
- Solder the cell circuit, place into the mold
- Pour liquid epoxy resin, vacuum/stand to remove bubbles
- Heat-cure into a transparent hard shell
- De-mold, trim edges, test
- Features: one-step molding, no lamination equipment — extremely low cost for small batches
Resin Panel Characteristics
| Advantages | Disadvantages |
|---|---|
| Low cost (mold + resin) | Weak long-term outdoor weather resistance (resin ages/yellows) |
| Shiny, attractive surface | Large sizes prone to warping/cracking |
| Small and delicate | Poor heat dissipation (resin conducts heat poorly) |
| Flexible production (irregular molds) | Limited power (typically 0.1-5W) |
Common Applications
- Solar garden/patio lights
- Night lights, flashlights, chargers
- Toys, electronic gifts, crafts
- Calculators, remotes, door plates
- Small sensors, smart-home gadgets
Buying Reminders
- Look for A-grade cells (resin panels also come in good and bad cell grades)
- Choose UV-resistant epoxy resin (ordinary resin yellows within months)
- Confirm IP waterproof rating for outdoor products (resin panels are waterproof themselves, but leads need sealing)
FAQ
Q: Can resin panels be made high-power?
A: Not recommended. Large resin panels have high internal stress in the resin — easy to warp/crack; power is typically within 5W. For high power use glass/ETFE/laminated processes.
Q: Why do resin panels yellow over time?
A: Ordinary epoxy resin isn’t UV-resistant; long sun exposure causes yellowing, lower transmittance and reduced generation. UV-resistant resin significantly delays this.
Q: Can resin panels be custom-shaped?
A: Yes. The resin process uses molds — round, heart-shaped, cartoon irregular shapes are all possible; a common way to customize gifts/toys.
Customized All-in-One vs. Sourcing Materials Yourself: Why Choose the SQTlot Module Solution?
| Comparison | Sourcing materials yourself | SQTlot custom modules |
|---|---|---|
| Material quality | Encapsulant grades vary wildly | Material selected by scenario (ETFE/PET/BC/glass), consistent batches |
| Process consistency | Handmade/small workshop, no yield guarantee | Production-line standard process + panel-by-panel testing |
| Certification | Lack of reliability data | Factory-direct, test reports and certification documents available |
| Custom response | High communication cost, uncontrollable lead time | Custom by drawing, full OEM/ODM process support |
| After-sales | No one accountable for quality | Source factory warranty, direct technical team access |
Core logic: Small-power custom shapes live or die by mould + resin responsiveness. SQTlot epoxy-resin modules support any shape, colour or logo, with samples in 7 days and fast small-batch turnaround.
Epoxy scenario: garden lights, festive decor, gifts and toys sell on looks; resin encapsulation turns a solar cell into a “printable electronic component” with short tooling cycles and flexible design changes.
B2B Procurement FAQ (MOQ / Lead Time / Certifications / Warranty)
Q: What is the MOQ?
A: Standard modules start at 500 pcs with tiered pricing; custom shapes/colors start at 1,000 pcs, with 5-10 sample pieces arranged first.
Q: What is the lead time?
A: Standard modules ship in 7-10 days; custom tooling + sampling takes 1-2 weeks, and mass production takes 3-4 weeks depending on process and quantity.
Q: Which certifications do you hold?
A: CE / RoHS / REACH / FCC test reports and Declarations of Conformity are available; UL / TÜV certification can be evaluated in advance (lead time and cost apply).
Q: What is the warranty?
A: 5-year module warranty plus 10-year power warranty (≤2% degradation in year one, ≤0.7%/year linear thereafter); terms are written into the contract.
Q: What customization is supported?
A: Size/shape, power/voltage, leads and connectors, adhesive backing, color/LOGO printing; ETFE / PET / BC / epoxy-resin / glass / flexible encapsulation are all available.
Q: Trade terms and payment?
A: EXW / FOB (Shanghai) / CIF supported; standard terms are 30% deposit + 70% before shipment, with monthly settlement negotiable for long-term partners.
