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 panel to choose, If you are looking for a portable solar panel, why not look think about the two solar panels that we have on offer here? You can choose between two different sizes; 55x77mm (0.5W) and 80x180mm (2W).

These panels are monocrystalline silicon solar panels, which is the main trend in the future. Comparing to polycrystalline silicon solar panel and thin-film solar panel, monocrystalline silicon solar panel performs higher conversion rate that up to 17%. The surface is covered by fine resin which makes it waterproof, together with a very sturdy back, it is really suitable for outdoor environment.

Depending on 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 peal OC voltage can be up to 10V. Because the voltage range is relatively wide, if you are going to use boards that require 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.

These panels have a 2mm JST connector attached to the panel for ease of incorporation in your projects.
