Meet Our Senior
Engineers at
Caravan Salon
Düsseldorf.
Book a private session with Sungold Solar's RV solar specialists at Hall 13, Booth 13D52. Discuss your project, see live demos, and get engineering-level answers — Aug 28 to Sep 6, 2026.
Purpose-Built Solar
for Every RV Challenge
Sungold RV solar solutions are engineered for motorhomes, caravans, trailers and refrigeration units. Our systems combine lightweight panels, anti-shading technology, MPPT controllers and OEM-ready configurations — eliminating dead batteries, reducing idle expenses, and protecting cold chain integrity across Europe and North America.
-
Rooftop Heat BuildupCool-Back™ thermal backing (0.2 W/m·K) reduces heat transfer, keeping cells operating 5°C cooler for stable year-round output.
-
Partial Shading from AccessoriesCell-level shadow management isolates shaded cells, preventing whole-string collapse from AC units, antennas, and tree shade.
-
Road Vibration & Wind LoadFiberglass-reinforced composite backsheet (≥20 MPa bending strength) withstands continuous 10–60Hz road vibration, mile after mile.
Cell-Level Shadow
Management Technology
Unlike traditional bypass diodes that sacrifice entire panel strings, Sungold's anti-shading architecture manages shadow at individual cell level — maintaining stable output when AC units, antennas, or trees partially cover your RV roof.
Cell-Level Bypass Architecture
Finer circuit segmentation means only shaded cells are bypassed. Unshaded areas continue generating full power — eliminating whole-string collapse common in conventional layouts.
Hotspot Elimination
Diode temperature maintained below 85°C during peak current. Prevents micro-crack formation from thermal cycling and reduces long-term degradation significantly.
Real-World Shading Scenarios
Proven performance under roof accessories, tree shade, and varying sunlight angles. Ideal for motorhomes at campsites, urban stops, and forest environments.
Sungold Products
Three purpose-built solar solutions for European RV and caravan OEMs — each engineered for specific mobile power challenges.
PA621 Series
Lightweight RV & Caravan Panel
- Cool-Back™ thermal backing — 0.2 W/(m·K), cells 5°C cooler on hot rooftops
- Vibration-resistant 10–60Hz — fiberglass ≥20 MPa, micro-crack free
- Cell-level anti-shading — 88%+ output vs. 35% conventional under partial shade
- 4.4 kg/m² — 15-min install, no roof penetration, CE & IEC 61215/61730
PA219 Series
TÜV Flexible Solar Panel
- Ultra-thin <3mm — conforms to curved roofs and side panels, no stress
- ETFE surface — 10–15yr UV stability, anti-reflective, self-cleaning
- 3M VHB pre-applied — 15-min tool-free install, IP65 rated
- ~2.5 kg lightweight — EU 600W/800W balcony inverter compatible, OEM configs available
Hi-Power Series
High-Wattage Portable Panel
- 440W+ peak output — 23% TOPCon efficiency, charges 1–1.25kWh stations fast
- IEC TS 63163 certified — 30-min full immersion tested, industry-leading safety standard
- IP67 waterproof + impact-resistant — extreme temp, humidity and dust ready
- Universal connectors — MC4 / Anderson / XT60, plug-and-play with all major stations
BC Back-Contact
Cell Technology
Our BC (Back-Contact) solar cells move all electrical contacts to the rear surface — eliminating front-side metal shading to maximize light collection and create a clean all-black aesthetic. The result: 25% cell efficiency with superior thermal stability for premium RV, marine, and residential rooftop installations.
25% Cell Efficiency
Front-side grid-free design maximizes active cell area and light capture for the highest energy density on limited roof space.
~70°C Hotspot Reduction
Multi-path rear current routing redistributes current under partial shading, preventing heat concentration. Zero hotspot breakdown record.
Anti-Microcrack Design
Unique rear "straight-line" ribbon reduces stress vs. Z-shaped layouts, improving microcrack resistance during transport and vibration.
All-Black Aesthetics
Clean, uniform all-black surface integrates seamlessly into premium RV, BIPV carport, and residential rooftop installations.
