We manufacture 4 models of rigid solar panels at our Fujian facility. Every panel pairs monocrystalline silicon cells with 3.0mm low-iron tempered glass and a CNC-cut anodized aluminum frame — built for permanent installation that survives 25+ years of direct sunlight, rain, snow, and thermal cycling. Our lineup spans two voltage tiers: the 18V series (BF-PV-P50W, BF-PV-P100W, BF-PV-P150W) for 12V battery systems, off-grid cabin lighting, and our smaller power stations; and the 36V BF-PV-P250W for 24V systems and the BF-PPS-1500W / BF-PPS-3000W power stations. Junction boxes carry IP65 protection across the lineup, and the operating temperature range covers -40 to 85 degrees C — the same panel deploys in Scandinavian winters and Saudi Arabian rooftops.
These panels are voltage-matched to our BF-PPS portable power station series and pair seamlessly with our BF-PV-F foldable solar panel series for projects that need both permanent and portable deployment. Standard MC4 output connectors mean compatibility with any third-party charge controller, hybrid inverter, or grid-tie micro-inverter that accepts MC4 input — no proprietary lock-in.
Rigid Solar Panel Specifications
All four models share the same construction approach: monocrystalline silicon cells laminated under 3.0mm low-iron tempered glass with an anodized aluminum frame. The cells are arranged in a 36-cell configuration. The front-glass transmission rating is 0.93 (93 percent) — this is the white pattern-textured glass standard used across our rigid panel lineup. Junction boxes are IP65 rated.
18V Series — BF-PV-P50W / P100W / P150W
The 18V tier targets 12V battery systems, off-grid LED lighting, small power stations (BF-PPS-300W and BF-PPS-600W), and DIY camper / RV permanent rooftop installations. Each model uses 36 cells in series for an open-circuit voltage of 21.6V, falling to a working voltage of 18V under load — the standard nominal voltage for 12V system charging via PWM or MPPT charge controllers.

The 36V tier targets 24V battery systems, larger power stations (BF-PPS-1500W and BF-PPS-3000W), and grid-tie micro-inverter installations. The higher voltage allows two panels in parallel to hit the BF-PPS-3000W's 500W maximum solar input rating, or four panels in series to drive a 96V hybrid inverter.

Rigid Glass vs Foldable Lamination: Which Is Right for Your Project?
We produce both the BF-PV-P rigid glass series and the BF-PV-F foldable laminate series.

Construction and Quality Control
Our rigid solar panels are built on the same Fujian production line that has shipped solar lighting, power stations, and portable foldable panels to 30+ countries since 2013. The rigid panel line uses dedicated lamination presses, EVA cell encapsulation, and aluminum frame extrusion — the same equipment class found at tier-1 Chinese solar manufacturers.
Construction details:- Front glass: 3.0mm low-iron tempered glass with white textured pattern, 93% light transmission
- Cell encapsulation: EVA (Ethylene-Vinyl Acetate) film, dual-side, vacuum laminated
- Backsheet: TPT (Tedlar-PET-Tedlar) composite for moisture barrier and electrical isolation
- Frame: Extruded aluminum with anodized surface treatment for corrosion resistance
- Junction box: IP65 rated with three bypass diodes (one per cell substring)
- Output cable: MC4 connectors with IP67 cable seals, 1m standard length
- Cell sorting — incoming cells binned by efficiency class before lamination to ensure uniform output within each panel
- Vacuum lamination — 145 degrees C dwell with vacuum hold to eliminate air pockets and ensure cell adhesion
- EL (electroluminescence) inspection — every panel imaged for micro-cracks and inactive cells before frame assembly
- STC flash test — output power verified under 1000W per square meter / 25 degrees C / AM1.5 simulated sunlight for every production unit
- Insulation resistance test — 1000V DC applied between cell array and frame ground to verify electrical isolation
- Visual inspection and packaging — corner protectors, foam inserts, and pallet-strapping for transport
- Materials and workmanship: 2 years against manufacturing defects
- Power output: 90% of nominal at year 10, 80% at year 25 (linear degradation, typical industry standard)
- Replacement policy: Defective units replaced or repaired at our cost; freight terms per contract
For project tenders requiring formal certifications (CE, RoHS, IEC 61215, IEC 61730, UL 1703 for North America), we can arrange third-party testing through TUV, Intertek, or SGS at quoted per-model fees. Typical certification timeline is 4-8 weeks. Existing CE-marked production for portable solar panels may inform faster turnaround on rigid panel CE submissions.
How to Order: From Inquiry to Delivery
Step 1: Specify Your Project
Tell us which models, quantities, target market, and deployment timeline. We respond within 24 hours with FOB pricing, MOQ guidance, and lead time estimates. For projects above 200 panels, please share your installation context (rooftop, ground array, telecom, off-grid lighting) — this helps us recommend the right voltage tier and suggest mounting accessories.
Step 2: Sample Evaluation
Order 1-2 sample units per model for testing. Sample shipping worldwide via DHL or air freight (panels over 7 kg do not qualify for standard parcel rates). We recommend testing under your local sunlight conditions, voltage compatibility with your charge controller, and mounting compatibility with your hardware. Sample cost applies toward your first bulk order.
Step 3: Bulk Order and Production
Confirm specifications, quantity, junction box configuration, cable length, and any branding requirements. We issue a proforma invoice. Payment terms: T/T 40% deposit, 60% balance before shipment (or as agreed in contract). Production lead time: 20-35 days for standard models, 30-50 days for OEM/custom orders.
Step 4: Quality Inspection and Shipping
Every production batch undergoes EL inspection, STC flash test, and insulation resistance verification. We send QC photos and test reports before packing. Third-party inspection (SGS, Bureau Veritas, Intertek) welcome at our factory. Glass panels ship in foam-lined cartons on pallets — typical 40HQ container holds approximately 500 BF-PV-P100W panels or 200 BF-PV-P250W panels with proper packaging density.
Step 5: Delivery and Installation Support
FOB Xiamen / Fuzhou, CIF, or DDP to your port or warehouse. We handle export documentation including commercial invoice, packing list, certificate of origin, and (where applicable) third-party test reports. Installation guides provided in PDF form for each model.
