Large Pack of 30 Mini Solar Panels 5 V 75 mA 80 x 45 mm Photovoltaic Cells in Epoxy with Soldering Points for Classes and Models
You already have the maximum available quantity in your cart.
A large pack of thirty mini solar panels will equip an entire school class, a summer camp focused on technology, or a workshop where a larger number of solar products are created. Each module measures 80 x 45 mm and provides a voltage of 5 V and a current of 75 mA in direct sunlight. Thirty pieces allow each student to work with their own panel without waiting for others. The cell is protected by a transparent epoxy encapsulation and the back is made of a printed circuit board with marked positive and negative contacts. The modules have identical parameters and can be freely combined with one another.
When connected in series, the voltage of the panels adds up, while in parallel, the current adds up. A larger number of modules can create a solar area for powering a small pump, fan, light decoration, or for charging batteries. The solid circuit board on the back allows the panels to be glued or screwed onto a common frame. The soldering points are located outside the active area, ensuring that the wires do not obstruct light. In teaching, the thirty identical panels allow for easy comparison of measurement results between groups, demonstrating the effects of orientation, shading, and light intensity. The panels can also be used in modelling, for example in solar cars, boats, or windmills powered by a small motor. A simple charger for small batteries or solar power for a weather station or sensor in the garden can also be built from several modules. With a larger number of pieces, you can afford to experiment with different connection variants without worrying about running out of panels or damaging one during experiments.
- Type – photovoltaic mini modules encapsulated in epoxy
- Number of pieces – 30 identical modules
- Voltage of one module – 5 V
- Current of one module – 75 mA
- Dimensions of one module – 80 x 45 mm
- Surface – transparent protective layer of epoxy
- Back side – printed circuit board with contacts + and − and soldering points
- Usage – school education, camps, clubs, modelling, and solar assemblies
- Contents of the package – 30 solar panels 5 V 75 mA measuring 80 x 45 mm
Store the modules in a dry environment and separately from sharp tools that could scratch the surface. Dirt on the surface can be wiped off with a soft cloth. When soldering, pay attention to the correct polarity and do not overheat the contacts. If the panels are charging a battery, add a diode to the circuit to prevent reverse discharge in the dark.
Thirty identical solar modules are a practical choice for teachers, club leaders, and DIY enthusiasts with more extensive plans. The uniform format of 80 x 45 mm simplifies the design of models and the assembly of larger panels. The transparent epoxy encapsulation protects the cells during frequent use. The pack is sufficient for an entire class and still leaves a reserve for experiments and spare parts.
