Custom Solar Panels
Built for Your Exact Application
Flexible, rigid, and portable solar panels manufactured to your voltage, size, logo, and wiring spec. Factory-direct from Sungold Solar — with engineering review, sample validation, and repeatable mass production.
Six Dimensions We Customize
Every custom solar panel project starts with a real engineering review. These are the variables we routinely adjust — without turning the conversation into a vague "contact us for details."
Voltage
Working voltage window tuned to match your MPPT, charge controller, or inverter profile. Avoid costly electronics mismatches at the source.
Power
Wattage target aligned to the installation area, cell technology (TOPCon, BC, PERC), and allowable power density for the enclosure.
Size
Custom dimensions in millimeters. RV rooftops, marine hatches, BIPV facades, and balcony rails all impose constraints standard panels ignore.
Color
Backsheet color, frame anodizing, and junction box options. Black-on-black BIPV finish or custom brand colorways for product line consistency.
Custom Logo
OEM branding on the panel face, junction box, and packaging. Serial number logic and nameplate datasheets your distributors can rely on.
Wiring Options
Cable length, exit position, connector type (MC4, Anderson, bare leads), and polarity orientation defined per application — not per catalog default.
Which Application Fits Your Project?
Custom solar panel geometry is usually driven by the installation scenario first. Start with the application, then work backwards to wattage and voltage.
RV / Van
Lightweight, flexible, and compact panels for motorhomes, campervans, and specialty vehicles. Low-profile framing eliminates shading nightmares on curved or irregular rooftops. Vibration and moisture ratings matched to real road conditions.
Explore RV Solar →Off-Grid & On-Grid
Rigid panels for homes, commercial buildings, remote sites, and telecom infrastructure. Designed for both off-grid battery systems and grid-tied applications where steady, repeatable output per batch is non-negotiable.
Explore Rigid Panels →Outdoor & Portable
Foldable solar kits engineered for camping, field work, emergency power, and mobile energy units. Lightweight construction, integrated carry handles, and multi-fold formats that survive rough handling.
Explore Portable Panels →Premium Kits
Highest-efficiency configurations using TOPCon or BC cell technology. Built for product lines where energy density, long-term consistency, and certifiable performance data are required to close distributor or retail contracts.
View All Products →OEM vs ODM — Choose the Right Path
Both are valid manufacturing routes. The wrong choice is treating them as the same word with different fonts. Here is what actually differs.
| Topic | OEM Custom Solar Panels | ODM Custom Solar Panels |
|---|---|---|
| Who owns the design | You bring approved drawings and specs; Sungold manufactures and controls process quality. | Sungold co-develops or proposes the module design, then locks the BOM with you. |
| MOQ & timeline | Often faster when the design is mature — fewer design loops required. | More iterations up front; worth it when you need a novel form factor engineered from scratch. |
| Certification path | Scoped to your existing module family where possible — faster compliance. | May require a separate test plan if the laminate stack is new. Plan time, not hope. |
| Best for | Buyers who already know exactly what the panel must be. | Buyers who know the install scenario but need the module invented to fit. |
The Custom Solar Panel Process
A structured workflow that catches drawing errors, voltage mismatches, and compliance gaps before they reach production — not after.
Requirement Review
You provide: drawing (even rough), target wattage, voltage range, application context, and destination market. Sungold checks whether the size, power, and structure are realistic for manufacturing — and flags what is missing before any money moves.
Output: requirement checklist + gap listEngineering Review
Cell layout, electrical margin, mechanical risk, junction box position, cable exit, connector type, and system compatibility are checked. This is where "possible" gets separated from "expensive and risky." You receive a clear feasibility verdict — not a polite non-answer.
Output: feasibility feedback + recommended design directionPrototyping
Sample units built to validate fit, electrical performance, visual standard, and handling. The goal is finding issues before the BOM is frozen — not making a showpiece for a catalog shoot. Flash data and improvement notes are shared with every sample batch.
Output: sample units + flash data + improvement notesCompliance Workflow
Certification scope depends on the sales market and application. Sungold reviews whether the project can leverage an existing module family, needs supplementary documentation, or requires a separate testing path. Environmental tests (salt mist, damp heat, flex fatigue) are scoped for marine and vehicle programs specifically.
Output: compliance document list + testing scopeMass Production Lock
After sample approval, BOM, materials, process notes, QC inspection standard, and production schedule are locked. Repeat orders match the first batch — not just approximately, but by spec. This step prevents the common problem of batch-to-batch electrical or dimensional drift.
Output: approved BOM + QC standard + production timelinePackaging, Labeling & Logistics
Inner box, outer carton, pallet plan, OEM labels, serial rules, and distributor-facing datasheets are aligned before shipment. For buyers with tariff or origin concerns — including Indonesia production routing via PT Sungold Solar Power — this is discussed before the purchase order is placed, not after goods arrive at the warehouse.
Output: label files + packing data + shipment informationMOQ & Lead Time — Numbers Without Fairy Tales
Custom solar panel MOQ moves with cell type, laminate stack changes, and certification scope. A structured milestone table is more useful than a single "4–6 weeks" promise.
| Stage | What Typically Happens | Planning Note |
|---|---|---|
| Sample / Pilot | Small batch to validate fit, finish, and electrical targets. Flash data and visual check included. | Freeze connectors, labels, and test criteria early — rework at this stage is the cheapest it will ever be. |
| First Mass Order | Line setup, materials lock, QC alignment to your acceptance sheet. | Seasonality affects material slots. Build schedule slack if your product launch date is fixed. |
| Repeat Orders | Matched power bins and mechanical tolerances to agreed specification. | Predictable deltas across batches. Useful for supply chain planning and distributor forecasting. |
Custom Solar Panel Certifications — Match the Country
Certification is not one universal stamp. Mismatching the cert path to the destination market is one of the most common and expensive OEM mistakes.
EU Distribution
CE-related module documentation within the EU context. RoHS and REACH awareness for system assemblies. Sungold maps the module family to the compliance pack your channel needs — not a generic PDF stack.
North America
UL-recognized routes or equivalent project-specific requirements. Align with your Authority Having Jurisdiction (AHJ) or corporate spec early — retrofitting compliance after tooling is committed is expensive and slow.
Marine & Harsh Ambient
Salt mist, damp heat, and flex fatigue testing where relevant. Test plan tied to how the module actually mounts — not to a boilerplate datasheet footnote about "suitable for marine environments."
Supply Chain & Origin
For North American and EU buyers with tariff or origin sensitivity: Indonesia production routing (PT Sungold Solar Power, Batam) is available where non-China origin helps your import scenario. No magic — just transparent routing options.
Custom Solar Panels vs Standard Modules
If an off-the-shelf module already hits your voltage, size, and certification needs — buy it. Custom solar panels earn their keep when integration pain or brand consistency would eat your margin anyway.
Choose Custom When...
- Standard sizes do not fit the installation geometry (RV roof, boat hull, BIPV facade).
- You need a specific Voc window for your charge controller or inverter.
- You are building a product line requiring brand-grade datasheet consistency.
- Your application involves vibration, moisture, or unusual surfaces that generic panels are not rated for.
- OEM branding, serial logic, and distributor-facing documentation are part of the product spec.
Stick with Standard When...
- Your roof or deck is basically flat and standard sizes fit without shading issues.
- A stock module already covers the voltage, power, and certification you need.
- You are installing a single system, not building a repeatable product line.
- Budget or timeline cannot absorb the sample-to-MP cycle that custom work requires.
Custom Solar Panel Questions
What is the difference between OEM and ODM custom solar panels?
ODM: Sungold co-develops or proposes the module structure, size, voltage logic, or installation approach — then locks the BOM with you. Best when you know the application problem but still need the module engineered to solve it.
MOQ, timeline, and who drives the certification details shift meaningfully between the two paths.
What MOQ should I expect for custom solar panels?
How long is lead time for samples and mass production?
Which certifications are available for custom solar panels?
— IEC-related performance and safety testing for general module qualification
— CE documentation for EU distribution channels
— UL-recognized routes for North American buyers
— Environmental add-ons (salt mist, damp heat, flex fatigue) for marine and vehicle applications
Confirm the destination market and application early — retrofitting compliance after tooling decisions is expensive.
Can Sungold match specific panel dimensions and voltage targets?
When should I choose custom solar panels instead of standard modules?
If an off-the-shelf module already hits your requirements — buy it. Custom solar panels earn their keep when integration difficulty or branding requirements would eat your margin anyway.
