SQTlot Custom BC Solar Modules
Product Overview
At SQTlot, we don’t just manufacture solar panels; we engineer custom power solutions. Our high-quality back-contact (BC) solar panels represent the pinnacle of solar technology, combining a stunning pure-black aesthetic with industry-leading efficiency.
Unlike standard panel suppliers, we specialize exclusively in custom, non-standard solar components. We understand that innovative products require power sources that fit perfectly. Our BC modules feature no busbar shadowing on the front, which maximizes light absorption and allows for conversion efficiencies exceeding 24%. This makes them the ideal choice for projects where appearance, space, and performance are non-negotiable.
Why Choose Our Custom BC Solar Panels?
Unmatched Customization Expertise
As a specialized OEM/ODM manufacturer, we excel at creating solar modules that off-the-shelf suppliers cannot. Whether you need a unique size, a specific voltage, or a special connector, our engineering team will bring your design to life.
Superior Aesthetics for Demanding Projects
The uniform, all-black appearance of our BC panels blends seamlessly into high-end rooftops, building facades (BIPV), and premium consumer products, enhancing the overall design.
High Power Density
Our back-contact technology eliminates front-side busbars, removing shading loss and maximizing light absorption. This results in higher power output per square meter, which is critical for space-constrained applications.
Robust & Reliable Construction
Custom-built does not mean compromised quality. Our panels are engineered with sturdy construction to ensure a long service life in various outdoor environments.
Low MOQ for Custom Projects
We support innovation with a minimum order quantity of just 100 pieces for customized BC modules, making us the perfect partner for both emerging and established brands.

FAQ
Q1: What makes your company different from other solar panel suppliers?
Unlike many suppliers who focus on standard-sized panels, we specialize exclusively in custom, non-standard solar components. Our entire process, from engineering to manufacturing, is optimized for OEM/ODM projects, giving us the expertise to handle unique and complex requirements.
Q2: What is the advantage of Back-Contact (BC) technology?
BC technology moves all electrical contacts to the rear of the solar cell. This eliminates the metal busbars on the front, which removes shading loss and results in higher conversion efficiency (over 24% for most of our models) and a clean, pure-black aesthetic.
Q3: What is the minimum order quantity (MOQ) for a custom BC panel?
Our MOQ for customized BC solar modules is 100 pieces. This allows us to support innovative projects and new product development with flexibility.
Q4: Can you customize the voltage and connectors?
Yes, absolutely. We can tailor the operating voltage, current, cable length, and connector types to ensure seamless integration with your specific device or system.
