This Small Solar Panel 55x70mm 0.5W is made of single-crystal material that performs high solar energy transformation efficiency. It has a fine resin surface and sturdy back suitable for outdoor environments.



Key Features

  • Made of single-crystal material (monocrystalline) that performs high solar energy transformation efficiency
  • Small but able to provide enough power for your DIY projects
  • A fine resin surface which makes it waterproof and a sturdy back suitable for outdoor environments
  • A 2mm JST connecter is attached to the penal, which makes it perfect to team up with most of our can-use-solar-power-supply boards


Many people like solar energy because it is simple, clean, and renewable. Especially when you are building outdoor projects, solar energy is one of the best solutions for power supply. Depending on the project you are going to build, there are many different sizes of solar panels to choose, If you are looking for a portable solar panel, why not look at this small solar panel that we are going to introduce today: Small Solar Panel 55x70mm 0.5W.
0.5W Solar Panel 55x77 is a monocrystalline silicon solar panel, which is the main trend in the future. Comparing to polycrystalline silicon solar panel and thin-film solar panel, monocrystalline silicon solar panel performs a higher conversion rate that up to 17%. The surface is covered by a fine resin surface which makes it waterproof, together with a very sturdy back, it is really suitable for the outdoor environment.
A 2mm JST connecter is attached to the penal, which makes it perfect to team up with some solar panel compatible boards produced by Seeed like:

Depending on the light intensity, the typical open circuit voltage is 5V. If you take it to a summer day with bright sunshine and no cloud in the sky, the peak OC voltage can be up to 10V. Because the voltage range is relatively wide, if you are going to use boards that require a narrow range of input voltage, such as Lipo Rider, to prevent any damage, please check whether the OC voltage is acceptable for the board before any connection.

    Looked good to start with, however in direct sunlight I get something more akin to 0.05 watts, not 0.5 watts. I would not recommend this product.
