175W All-Black BC Solar Panel with High Power Density

The CLR175BC uses back contact mono-crystalline solar cells, where all electrical contacts are moved to the rear side of the cell. Unlike conventional solar cells with visible front metal grid lines, BC technology creates a cleaner front surface with improved light absorption and a fully black appearance.

The result is a solar panel that offers both performance and aesthetics — an important advantage for premium applications such as RVs, yachts, camper vans, and outdoor equipment where the solar panel is part of the overall product design.

With a power output of 175W and a compact module size of 1320mm × 580mm × 30mm, CLR175BC provides a high wattage solution for installations where available space is limited.

How BC Solar Technology Helps 

For many solar buyers, choosing a module is not only about rated wattage. Real-world applications often involve limited installation space, partial shading, appearance requirements, and long-term reliability concerns.

BC technology helps solve several common problems faced by OEM brands and system developers.

Improved Solar Panel Shading Tolerance

Partial shading is a frequent issue in off-grid applications. RV roofs may have air conditioners, vents, and antennas. Boats may experience shadows from masts and equipment. Outdoor installations can be affected by trees, buildings, or surrounding structures.

Traditional solar modules may experience significant output reduction when part of the panel is shaded. BC solar cells improve current collection by placing electrical contacts on the back side of the cell, reducing front-side shading losses and helping maintain better energy generation under uneven lighting conditions.

For installers and system integrators, this means:

• More stable power generation in changing outdoor environments
• Better performance where full sunlight is not always available
• Reduced risk of customer complaints caused by shading-related losses
• Higher system value compared with standard solar panels

This makes CLR175BC a strong choice for applications where solar panels cannot always be installed in perfect conditions.

Premium All-Black Design for OEM Products

Appearance has become increasingly important for many solar applications. For RV manufacturers, marine brands, and premium outdoor equipment companies, the solar panel is part of the final product appearance.

CLR175BC features:

• Full black surface design
• No visible silver busbars or front grid lines
• Modern and uniform appearance
• Easy integration into premium product designs

Compared with conventional solar panels, the cleaner appearance helps OEM brands create products with stronger visual appeal and market differentiation.

Reliable Rigid Solar Panel Design for Outdoor Use

While flexible solar panels are useful for certain curved surfaces, many off-grid applications still require the mechanical strength and installation convenience of rigid modules.

The CLR175BC rigid structure provides:

• Strong mechanical protection
• Easier mounting with standard solar accessories
• Better long-term structural stability
• Compatibility with existing solar installation methods

For distributors and EPC companies, rigid solar modules can simplify installation and reduce project risks.

Recommended Applications

RV and Camper Solar Systems

RV and camper manufacturers need compact solar panels that maximize available roof space. CLR175BC provides a combination of high output, attractive design, and reliable outdoor performance.

Typical applications include:

• Camper vans
• Motorhomes
• Travel trailers
• Off-grid camping systems

The improved shading tolerance is especially useful because RV roofs often contain multiple components that can create partial shadows.

---

Marine Solar Applications

Marine environments require reliable energy solutions that can operate under changing sunlight conditions.

CLR175BC is suitable for:

• Yachts
• Sailing boats
• Fishing boats
• Marine auxiliary power systems

The all-black appearance also matches the premium design requirements of many marine products.

---

Off-Grid Power Systems

With its 175W output and 24V-class voltage characteristics, CLR175BC can be integrated into various small and medium off-grid systems, including:

• Remote monitoring equipment
• Communication systems
• Security devices
• Agricultural applications
• Battery charging solutions

---
