Pack of 50 Solar Cells 5 V 75 mA 80 x 45 mm Mini Photovoltaic Panels in Epoxy with Soldering Points for Schools, Workshops and Production
You already have the maximum available quantity in your cart.
This pack of fifty solar cells is designed for larger schools, technical clubs, workshops, and DIY enthusiasts who produce solar products in smaller batches. Each cell measures 80 x 45 mm and provides a voltage of 5 V and a current of 75 mA in sunlight. Fifty identical units can cover several classes or groups simultaneously, leaving enough panels for larger assemblies. The photovoltaic cell is encapsulated in clear epoxy, and the contacts for positive and negative are marked on the back of the printed circuit board. The identical parameters of all cells facilitate their interconnection.
By connecting them in series, the voltage increases, and by connecting them in parallel, the current increases, allowing the fifty cells to create a solar area for more powerful devices, such as small pumps, fans, or charging larger batteries. The back plate made of printed circuit board keeps the cell flat and firm, making it easy to attach to a frame, box, or model body. The soldering points are located outside the active area, so the wires do not cast shadows. This large pack is also appreciated by those who manufacture solar toys, garden lamps, or educational tools for other schools. In education, the same cells can be used to compare measurements between groups and demonstrate the effect of the angle of light incidence and shading on performance. A larger number of cells can also be used to build solar chargers, power for garden sensors, or lighting for model railways and nativity scenes. Spare cells are useful as replacements when repairing older solar lamps where the original panel has lost power or been mechanically damaged.
- Type – photovoltaic mini cells encapsulated in epoxy
- Number of units – 50 identical cells
- Voltage of one cell – 5 V
- Current of one cell – 75 mA
- Dimensions of one cell – 80 x 45 mm
- Surface – clear epoxy encapsulation protecting the cell
- Back side – printed circuit board with contacts + and − and soldering points
- Usage – schools, workshops, clubs, production of solar toys and lamps
- Contents of the pack – 50 solar panels 5 V 75 mA measuring 80 x 45 mm
Store the cells in a dry place, preferably in the original packaging, to prevent the surface from being scratched during handling. Clean the surface with a soft cloth before assembly. When soldering a larger number of cells, check the polarity and do not heat the contacts unnecessarily long. Include a diode in the circuit for charging batteries to prevent reverse discharge in the dark.
Fifty solar cells in one pack is an economical solution for institutions, workshops, and experienced DIY enthusiasts. The uniform size of 80 x 45 mm simplifies repeated assembly into the same products. The protective epoxy encapsulation keeps the cells in good condition even with intensive use. The large pack will last for many projects and teaching hours.
