How much power does a VSAT use? Seems like it must be a lot. Desktops
are definitely not a good idea with solar, but laptops would do fine
with a solar power system, since they generally use less than 10 Watts.
Whereas a desktop PC with a monitor draws maybe 100 Watts.
Instead of using VSAT for backhaul, consider using Wi-Fi for backhaul
connection to the internet. WiFi equipment has very light power
requirements -- solar is defintely used to power Wi-Fi installations in
remote locations.
