Custom BC Solar Panels 1.8W–5W
5V / 6V / 9V Output · ETFE / PVF / PET
Standard back-contact solar modules engineered for IoT sensors, smart wearables, GPS trackers and portable electronics — fully customizable size, shape & power, with zero minimum order.
Key Benefits of Our BC Solar Modules
Back-contact (BC) cells move all conductive contacts to the rear side — no front busbars to block light or crack.
Zero Front Shading
Higher power density in limited tiny space — more energy from the same footprint.
Outstanding Weak-Light Performance
Stable power output at dawn, dusk and in cloudy weather.
Lower Temperature Attenuation
Less power loss under high-temperature outdoor conditions.
Enhanced Mechanical Toughness
Resistant to vibration, thermal cycling and slight bending — fewer micro-cracks.
Standard Lamination Options: ETFE, PVF and PET
Three proven surface materials, matched to your usage environment.
ETFE (Aerospace-Grade)
Excellent UV resistance, anti-aging & self-cleaning. No yellowing or delamination for over 15 years — built for long-term unattended outdoor equipment.
PVF (Polyvinyl Fluoride)
Proven weather-resistant film with strong UV & salt-spray resistance. A reliable, cost-effective choice for outdoor, coastal and marine devices.
PET
Cost-effective option for indoor usage or sheltered semi-outdoor products with low long-term weather exposure.

Frequently Asked Engineering Questions
Straight answers from our engineering team.
Q1. What's the difference between ETFE, PVF and PET lamination?
ETFE is the premium outdoor material — long-term anti-UV, self-cleaning, no yellowing for 15+ years. PVF is a proven weather-resistant film with strong UV and salt-spray resistance, balancing outdoor durability and cost. PET is the economical choice for indoor or sheltered semi-outdoor products.
Q2. Can I customize power, voltage, size or shape?
Yes. We fully support customized power, output voltage, dimensions and irregular outlines. Send your installation space drawing and power demand — our engineers will design the most suitable layout for free.
Q3. Do you have a minimum order for samples?
No. We are a direct manufacturer without MOQ restrictions. You can order a single sample for laboratory testing before mass production, and we also offer flexible small-batch trial production.
Q4. Why choose BC back-contact cells for micro equipment?
BC cells eliminate the front metal grid that blocks light and can crack under bending or thermal shock. They deliver higher power density in limited space, better weak-light generation and longer service life for wearable and vibration-prone IoT devices.
Q5. Can you pre-install wires, connectors or anti-reverse diodes?
Absolutely. We can pre-solder JST micro connectors, IP67 waterproof cables, or integrate anti-reverse diodes to match your assembly needs — simplifying your workflow and lowering assembly costs.
Q6. Are these panels bendable for curved product shells?
They support slight bending with a minimum bending radius of 10× panel thickness. For large curved enclosures, we can customize segmented cell circuits and flexible substrates to avoid cell cracking.
