I need a solar panel to be used with Seed Solar Charger Shield V2.2. I want to build a device that run 1 year using solar panel and battery. Kindly suggest which type of solar panel i should use?
We have the 0.5w to 2.5w, it depends on your system power consumption, as well as battery capacity, sun light duration. I would suggest you to measure your system power consumption first and then come back to the solar panel selection.
