Monocrystalline Solar Cell 6"x6" or 156x156mm with 3BB
Monocrystalline solar cell 156x156 mm, 3BB : 4.9 W.
For DIY modules and prototypes; interconnection and encapsulation required.
Building a small panel, repairing a module or creating an educational prototype? This solar cell provides a defined size and contacts for designing the layout and interconnections yourself.
It is a component, not a ready-to-use panel: compatible ribbon, controlled soldering, mechanical protection and encapsulation are required. Calculate the complete circuit voltage and current before assembly.

Explore Flexibility with Our Photovoltaic Kits
In addition to individually sold solar cells and the custom solar cell cutting service, we have also created DIY photovoltaic kits that are the ideal solution for those who wish to generate solar power in a flexible and customized way. These kits are the practical starting point for beginning to experiment and understand the mechanisms of electricity generation through the photovoltaic effect. For this reason, they are very popular in school, university, and research center laboratories. Suitable for small to medium-sized projects, these kits are perfect for "off-grid" applications, isolated from other energy sources like the national power grid.
The construction of solar panels is an educational and fun experience, allowing for unique customization of voltage/current according to your needs. A unique aspect of our kits is the ability to adjust the panel's voltage by modifying the number of solar cells used.
| Number of Solar Cells | Voltage (Volt) |
| 12 | 6V |
| 24 | 12V |
| 36 | 18V |
This table clearly shows how the voltage varies in relation to the number of solar cells. It is possible to experiment with different configurations to achieve the desired voltage level for your project.
For beginners, our Learning ZONE offers a comprehensive resource, including videos, that provides details on how to perform soldering and correctly use all components.
In each kit, we always provide about 5% spare cells, ensuring sufficient coverage for any breakages during soldering or transport. In case of shipping issues, we are ready to assist and resolve any problems because your complete satisfaction is our 100% priority.
Images may not accurately depict the product for sale. The dimensions of the solar cells can vary by 1-2mm. For example, nominal 156mm or 6” cells can be 156-159mm.
Frequently asked questions
Is this a complete solar panel?
No. It is a single cell to be integrated into a module designed, interconnected and protected by the user.
How can voltage and current be increased?
Cells in series add voltage; cells in parallel add current. Use matched cells and size the circuit for the load.
Is the cell fragile?
Yes. Avoid bending and point pressure and handle it with suitable tools and support.
How are the busbars connected?
Compatible ribbon and flux, controlled temperature and experience are required to limit thermal stress and breakage.
Can it be used outdoors without protection?
No. Moisture, impact and weather require properly designed encapsulation.
