Monocrystalline Solar Cell 3"x6" or 79x159mm with 5BB
Monocrystalline solar cell 79x159 mm, 5BB : 2.78-2.85 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 cutting service for solar cells, we have also created DIY photovoltaic kits that are the ideal solution for those who wish to generate solar energy in a flexible and customized way. These kits are the practical starting point for beginning to experiment and understand the mechanisms of generating electrical energy through the photovoltaic effect. For this reason, they are very popular in school laboratories, universities, and research centers. Suitable for small and medium-sized projects, these kits are perfect for "island" applications, isolated from other energy sources like the national electrical grid.
Building solar panels is an educational and fun experience, allowing for a unique customization of voltage/current according to your needs. A unique aspect of our kits is the ability to adapt 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. You can experiment with different configurations to achieve the desired voltage level for your project.
For beginners, our Learning ZONE offers a complete resource, including videos, that provides details on how to perform soldering and correctly use all components.
In each kit, we always provide about 5% of replacement cells, ensuring sufficient coverage for any breakages during soldering or transport. In case of problems due to shipping, we are ready to assist you and resolve any issues, as your complete satisfaction is our 100% priority.
The images may not accurately represent the product for sale. The dimensions of the solar cells may 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.
