Sunchees supports all these customizations for OEM clients, ensuring seamless integration into your target market.

Technical Comparisons: Choosing the Right Technology

Shingled vs. Normal Solar Modules

Feature	Shingled Modules	Normal Modules
Design	Laser-cut cells overlapped, no ribbons	Cells connected with visible ribbons
Efficiency	Higher (2%-5% gain by reducing resistance and shading)	Slightly lower due to ribbon shading
Aesthetics	Sleek, modern look ideal for rooftops	Traditional appearance
Durability	Better mechanical strength, less stress on cells	Ribbon solder points more prone to microcracks
Cost	Higher due to advanced manufacturing	Lower, mature production processes

Verdict: Shingled modules are ideal for premium markets prioritizing aesthetics and efficiency. Sunchees’ OEM shingled panels use advanced conductive adhesives and simplified stacking processes for superior performance.

Bifacial vs. Monofacial Solar Panels

Feature	Bifacial Panels	Monofacial Panels
Power Generation	Front and rear sides generate power using reflected light	Power generation only on the front side
Energy Yield	5%-30% higher in high-reflectivity environments	Consistent performance in standard installations
Applications	Open fields, snowy areas, white rooftops	Rooftops, small-scale off-grid systems
Cost	Slightly higher due to dual-glass structure	Lower

Verdict: For utility-scale or reflective environments, bifacial panels deliver better ROI. Sunchees OEM options include both monofacial and bifacial modules with customizable backsheet colors.

Flexible vs. Rigid Solar Panels

Feature	Flexible Panels	Rigid Panels
Weight	Ultra-light, perfect for portable or weight-sensitive uses	Heavier, designed for permanent installations
Durability	Less resistant to impact and scratches	Robust against harsh weather
Efficiency	Slightly lower due to flexible encapsulation	Higher with advanced cell technologies
Applications	RVs, yachts, backpacks, curved surfaces	Residential, commercial, and utility-scale solar
Cost	Higher per watt	Lower per watt due to scale production

Verdict: Flexible panels are excellent for niche markets, while rigid panels remain the mainstream choice for most solar projects. Sunchees supports both options for OEM customization.

PERC vs. TOPCon vs. HJT vs. IBC Cell Technologies

Technology	Advantages	Limitations	Best For
PERC	Low cost, mature technology, ~22% efficiency	Light-induced degradation (LID)	Budget-friendly projects
TOPCon	Higher efficiency (23%+), better temperature performance	Slightly higher cost, complex process	Commercial & industrial installations
HJT	Excellent low-light performance, high bifaciality, low-temperature process	High equipment cost	Premium residential & flexible panels
IBC	Highest efficiency (24%+), sleek aesthetics, no front contacts	Most expensive, complex manufacturing	High-end rooftop systems

Verdict:

PERC for cost-effective, large-scale projects.
TOPCon for those seeking a balance of efficiency and price.
HJT & IBC for premium, differentiated OEM products.

Sunchees can OEM all four technologies, helping brands target multiple market segments.
