That’s not how we do it. Our antennas don’t need solar power. And a repeater would need to be on a substantial base to be effective over more than a short distance.
That's why they're in the hills. Height = Might on UHF/VHF.
The repeaters we deploy all have battery backup and solar to keep those batteries charged. Of course our primary source of power is hardlined electrical power.
We've actually had a recent case where one of our repeaters lost power for four days. We had enough battery backup & solar to stay online for three of those four days. (We're in process of adding additional battery to extend uptime in event of a longer outage.)
