The Monocrystalline Solar Cell (100 mA, 5V, 75x60 mm) is a maximum efficiency monocrystalline solar cell. It is encapsulated in a clear epoxy to protect it against physical impact and harsh outdoor environments. If your application needs a higher voltage supply source, you can wire multiple solar panels in series.
You can wire the positive terminal of solar panel #1 to the load, and connect the negative terminal of solar panel #1 to the positive terminal of solar panel #2. In this wiring, the total voltage delivered to the load will be doubled and the rated current supply will remain the same.
