Monocrystalline solar cell 2.5”x2.5” or 62x62mm of 1BB
Monocrystalline solar cell 62x62 mm, 1BB: 0.75 W.
For DIY modules and prototypes; interconnection and encapsulation required.
Building a small panel, repairing a module or creating an educational prototype? This photovoltaic cell provides a defined size and contacts for planning the layout and interconnections.
It is a component, not a ready-to-use panel: compatible interconnections, controlled processing, mechanical protection and encapsulation are required. Calculate 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 do-it-yourself photovoltaic kits that are the ideal solution for those who wish to generate solar energy flexibly and customized. These kits are the practical starting point to begin experimenting and understanding the mechanisms of electricity generation through the photovoltaic effect. For this reason, they are very successful in school labs, universities, and research centers. Suitable for small to medium-sized projects, these kits are perfect for "island" applications, isolated from other energy sources like the national power grid.
The construction of solar panels is an educational and fun experience, allowing 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. You can experiment with different configurations to achieve the desired voltage level for your project.
For beginners, a complete resource, including videos, is available in our Learning ZONE, providing details on how to solder and correctly use all components.
In every kit, we always provide about 5% spare 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 because your complete satisfaction is our top priority.
Images may not accurately reflect 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 connections made?
The method and materials depend on front or rear contacts. Compatible ribbon or connectors and controlled temperature are required.
Can it be used outdoors without protection?
No. Moisture, impact and weather require properly designed encapsulation.
