Solar Panel Care when on vacation and EMP Damage
I had two questions about my solar panels that needed expert answers to. For the answers, I went directly to the manufacturer of my panels, Grape Solar in
. To get the answers I spoke with their Technical Help, an Electrical Engineer at 1-877-264-1014 for the answers to my questions. California
(1) I plan on traveling, leaving the house empty and unattended for 30-90 days in length multiple times a year. I needed to know what is a safe way to leave the solar system during that time, operating or disconnect the panels?
Grape Solar said no, do not disconnect the panels but instead leave a light load on the system such as a small inverter or a 12-volt night light hooked up directly to the batteries.
(2) Will solar panels be damaged by an EMP (Electro Magnetic Pulse) event?
Grape Solar said the panels should not be affected by an EMP Event. If not already, ground the frames to a typical 8-foot ground rod driven into the ground. However, the rest of the components connected with long wires will probably be damage!
