Set of 3 Mini Solar Panels 5 V 75 mA 80 x 45 mm Epoxy Photovoltaic Cells with Soldering Points for DIY Projects and School Models
You already have the maximum available quantity in your cart.
The set of three mini solar panels is ideal for DIY enthusiasts who want to experiment with solar energy on a larger scale. Each cell measures 80 x 45 mm and delivers 5 V at a current of 75 mA under full illumination. You can connect the three identical pieces in series for higher voltage or in parallel for higher current, or divide them into three separate projects. The surface is protected by a transparent epoxy encapsulation, and the back of the circuit board features clearly marked contacts. This set is suitable for workshops, electronics clubs, and experiments with children at home.
When connected in series, the voltage of the individual cells adds up while the current remains the same; conversely, when connected in parallel, the current adds up while the voltage remains the same. With three pieces, you can practically explore the basics of electronics while also obtaining a power source for more demanding models. The flat panels with a solid back made of circuit board can be glued side by side onto a common board, the roof of a model, or the lid of a box. The soldering points are located on the back, so the connecting wires are not visible from the front. The set of three pieces is also suitable for comparative experiments, such as how the performance of the cell is affected by the angle of incidence of light, shading, or distance from the lamp. You can place each panel differently and observe the differences on a voltmeter. Such measurements are illustrative for both children and adults and demonstrate why large solar power plants track the sun. After the experiments, the panels can easily be used in other projects.
- Type – mini solar panels with cells encapsulated in epoxy
- Number of pieces – 3 identical panels
- Nominal voltage – 5 V per panel
- Current – 75 mA per panel
- Dimensions of one panel – 80 x 45 mm
- Surface – transparent epoxy encapsulation resistant to moisture and corrosion
- Back side – circuit board with contacts + and − and soldering points
- Usage – DIY electronics, solar models, physics education, and charging small batteries
- Package contents – 3 solar panels 5 V 75 mA measuring 80 x 45 mm
Position the panels so that they receive direct sunlight without shade, as even partial shading of one cell will reduce the performance of the entire series. Clean the surface with a soft damp cloth without aggressive agents. Solder briefly and at an appropriate tip temperature. When charging a battery, include a diode in the circuit to prevent back discharge.
This trio of mini solar panels offers more options than a single cell and allows for the construction of more powerful solar products. The compact size of 80 x 45 mm and protective epoxy encapsulation facilitate installation into models, boxes, and educational tools. The panels are easy to solder and connect as needed for the project. This set is suitable for DIY enthusiasts, model makers, and teachers who wish to demonstrate solar energy in practice.
