Polynet Solar Solutions engineers custom TOPCon flexible solar panels for B2B customers — EPC contractors, solar distributors, system integrators, OEM brands and project developers — who need lightweight photovoltaics that integrate into a product, a vehicle, a vessel or a project site rather than sit on a standard roof rack.
Lightweight Solar Power Designed Around Your Application
Standard rigid modules force your design to fit the panel. Our flexible platform works the other way around: modules are engineered around the dimensions, curvature, voltage and power your product or project actually requires. The range spans a 3.0 kg, 200 W laminate for curved vehicle and vessel surfaces up to 535 W formats for larger off-grid arrays — a 200 W to 535 W standard flexible platform, with other power ratings, dimensions and voltages evaluated per project.
Why Choose Custom Flexible Solar Panels from Polynet?
Advanced high-efficiency cell technology. The standard flexible platform reaches module efficiencies up to 20.10% (PNM535M10, STC), built on high-efficiency monocrystalline cells in a thin, lightweight laminate.
Built for curved and irregular surfaces. Ultra-thin, flexible construction adapts to gently curved substrates — vehicle roofs, boat decks and arches, container and cabinet tops — without rails or ballast. The 200 W model measures just 2.14 mm in thickness with an ETFE front sheet.
Customized dimensions and electrical output. Length, width, cell layout, voltage and power are configured around your available mounting area and system requirements, within the practical limits of cell geometry and production processes.
Lightweight, low-profile installation. From 3.0 kg in the 200 W class to 9.0 kg in the 535 W class. No glass, no frame — the 200 W model installs rail-free using fastening eyelets or full-surface bonding, with no specialist personnel required.
Positive power tolerance. All models in the PNM390~535M10 flexible series are rated (0, +5 W): the modules you receive deliver at least nameplate power. Power tolerance for the PNM200 model is to be confirmed.
Designed for demanding outdoor projects. IP68 junction boxes (IP67/68 on the 200 W model), MC4-compatible connectors, an operating range of −40°C to +85°C on the M10 flexible series, and salt-mist test coverage (IEC 61701) stated on the 200 W model datasheet.
Product Applications
RVs, campervans and caravans — lightweight curved-roof charging that preserves payload, clearance and roof aesthetics.
Marine and boat systems — low-profile laminates for decks, cabin tops and arches, configured for humid, salt-laden environments.
Balcony solar solutions — lightweight modules supplied to balcony-PV assemblers and urban distribution partners for installations where roof access or load capacity is limited.
Off-grid power systems — array building blocks for telecom, water pumping, farms and remote facilities (see our Off-Grid & Remote Power Solutions page).
Solar lighting solutions — panels matched to charge controller, battery and luminaire duty cycles for standalone lighting.
Product-integrated photovoltaics — PV engineered into OEM equipment: cabinets, utility vehicles, sensors and mobile machinery.

Frequently Asked Questions
1. Can I order flexible solar panels in custom sizes?
Yes. Length, width, cell layout, power and output voltage are configured against your available mounting area, subject to cell dimensions and production requirements. Send your outline drawing and target specifications for an engineering evaluation.
2. Can the panels follow curved surfaces?
Yes — the laminates are designed for gently curved and irregular surfaces. They must not be folded or creased, and the minimum bending radius is confirmed for each construction during engineering review before mass production.
3. Can you match the panels to my battery and charge controller?
Yes. Provide the battery chemistry, nominal system voltage, charging voltage window and the controller's input limits; we propose the cell arrangement and module voltage so the array sits correctly inside the MPPT operating window.
4. Are they suitable for RV and marine use?
Yes, they are configurable for both. Final materials, sealing, connectors and mounting should match the expected exposure to water, salt, vibration, heat and UV. Note the 200 W model datasheet warranty condition: panels must be fixed to all provided fastening eyelets or glued over the entire surface, and sustained vibration may limit warranty coverage.
5. How are the panels mounted?
Rail-free installation with the provided fastening eyelets (bolt-through or laced) or full-surface adhesive bonding. Adhesive specification is recommended per substrate and project.
6. What certifications do the modules carry?
The 200 W model datasheet lists testing to IEC 61215 Ed.2, IEC 61730 and IEC 61701 (salt mist), with RoHS lead-free compliance and TÜV SÜD, CE and ISO marks shown on the datasheet. The higher-power series datasheets carry TÜV SÜD and CE marks. Project-specific certificate requirements should be raised during quotation.
7. What warranty applies?
The 200 W model carries a first-year degradation below 2.5% and 85% output at year 25. The PNM390~535M10 flexible series carries 12 years of materials-and-workmanship cover and a 25-year linear output guarantee at 84.8%.
8. What information do you need for a quotation?
Dimensions or outline drawing, target power, system/battery voltage, quantity, surface curvature, cable and connector requirements, mounting method, operating environment and any certification requirements.
