I got a solar panel that I can control with an app on a smartphone. I still don't understand why because it's not fully installed. I thought this was just a DC generator plugged into a DC-to-AC converter (an "inverter") and nature did its thing to autobalance the flow of electricity. I'm excited to find out what the app does and why these panels need a WiFi password.
