Set of 20 Solar Panels 5 V 75 mA 80 x 45 mm Epoxy Mini Photovoltaic Cells with Soldering Points for School Projects and Clubs
You already have the maximum available quantity in your cart.
This set of twenty mini solar panels is designed for schools, hobby clubs, and workshops where multiple solar products are built simultaneously. Each panel measures 80 x 45 mm and provides a voltage of 5 V and a current of 75 mA in full sunlight. Twenty pieces are sufficient for each participant in the club to build their own solar model, with extra panels available for replacements or experiments. The photovoltaic cell is encapsulated in transparent epoxy, and the back features a printed circuit board with marked positive and negative contacts. All panels in the set have the same parameters, allowing for arbitrary combinations.
By connecting the panels in series, the voltage increases, while parallel connections increase the supplied current. Thus, from twenty modules, a smaller solar surface can be assembled to power a fan, a small pump for a fountain, or to charge batteries in longer projects. The back board made of printed circuit board provides rigidity to the panel and allows it to be adhered to a base, box, or model body. The soldering points are outside the active area of the cell, ensuring that the wires do not shade the incoming light. For club leaders, it is advantageous that everyone works with the same type of panel, making it easy to compare measured voltage and current values. During lessons, it can be demonstrated how performance is affected by the angle of tilt towards the sun, shading of part of the area, or distance from the lamp.
- Type – photovoltaic mini panels encapsulated in epoxy
- Number of pieces – 20 identical panels
- Voltage of one panel – 5 V
- Current of one panel – 75 mA
- Dimensions of one panel – 80 x 45 mm
- Surface – transparent epoxy encapsulation
- Back side – printed circuit board with contacts + and − and soldering points
- Suitable for – electronics clubs, physics teaching, modelling, and DIY projects
- Contents of the package – 20 solar panels 5 V 75 mA measuring 80 x 45 mm
Store the panels in a dry place and protect their surface from scratching by sharp objects. Dust and fingerprints can be removed with a soft cloth to ensure the cell receives as much light as possible. When soldering, work quickly and do not heat the contacts for too long. When charging batteries, include a diode in the circuit to prevent back discharge through the panel in the dark.
Twenty solar panels in one package will cover the needs of a smaller class, club, or DIY enthusiast with a larger project. The uniform size of 80 x 45 mm facilitates installation into models and assembling into larger surfaces. The protective epoxy encapsulation keeps the cells functional even with repeated use. This set is a practical foundation for teaching renewable energy sources and for home experiments with solar energy.
