What Solar Panels We Are Selling for Residential
Why Choose Sevendan Energy for Residential Solar Projects?
HOA‑Friendly All‑Black Aesthetics
Our residential modules are designed to meet both performance and appearance expectations:
- All‑black glass, frame, grid lines, and encapsulation
- Uniform cell color for a clean rooftop look
- Ideal for HOA‑approved residential installations
Higher Energy Yield, Fewer Panels
Our residential modules use advanced TOPCon cells with 25.5% efficiency, exceeding the industry norm. Higher cell efficiency means:
- More power per square foot
- Fewer panels per rooftop
- Cleaner layouts and lower BOS costs
This makes our 440W / 450W modules ideal for space‑constrained residential rooftops and HOA‑regulated neighborhoods.
Fire Safety Starts with Electrical Components
Solar panels themselves do not burn—junction boxes, connectors, and cables do. That’s why we invest heavily in the components that matter most.
Our safety design includes:
- UL & TÜV certified junction boxes, rated up to 30A (vs. 15–20A commonly used in the market)
- Original Stäubli MC4‑Evo 2 connectors with UL, IEC & JET certifications
- UL94‑V0 flame‑retardant rating for enhanced fire resistance
- 1200mm, 4mm² (12 AWG) cables for higher current capacity and reduced heat buildup
This electrical architecture significantly lowers the risk of overheating and rooftop fire incidents—protecting both homeowners and installers.
Reinforced Frame Design for High‑Wind & Hurricane Zones
Residential projects in coastal and high‑wind regions demand more than standard frames.
Our modules feature thickened, high‑strength aluminum frames (6005‑T5) with reinforced wall thickness:
- Front (A‑side): 1.6mm
- Side (B‑side): 1.8mm
- Rear mounting side (C‑side): 2.0mm
Compared with typical 1.2–1.4mm frames, this structure provides superior resistance to wind uplift and torsion—ensuring every panel remains a reliable part of the system, not its weakest link.
Certified Quality You Can Trust
All residential modules are fully certified to meet U.S. and international standards:
- UL certified for the U.S. market
- TÜV certified for global quality compliance
Every product we deliver reflects not only our brand—but our customers’ reputation in the market.
