I took the original photo back in mid-November (top left) and have had a tough time finding additional information. For a while, I thought it was under DDOT's jurisdiction but I learned that it was on the Navy's property. Navy's communication team didn't respond so I decided to do my own investigation.
I went back on January 31 and got some information from the back of the solar panel--somewhere you can always find it (bottom left). There, I was able to find out that King Fisher Company, Inc made this 2.5 watt solar cell kit.
- It's doesn't take a lot of watts to power a call station,
- Call boxes can be installed by many different groups (universities, military compounds, parking garages, businesses, cities, counties),
- For that reason, it's difficult to find information on an overall network.
