Just a quick update. We installed solar panels from Tesla a month ago and yesterday the power company installed the new power meter. So now the signals (and everything else) is solar powered.
Got them from Tesla. It’s not the solar roof I envisioned which was wildly popular and sold very fast but it was very expensive. Tesla was a great company to deal with and the entire process from 1st meeting with the salesman until the system was up and running was a little over 2 months.

Excellent! We put solar panels on our home, and they were off to a great start, but we divorced and sold the house well before they paid for themselves. C’est la vie. The panels did not really add value to the sale price, but I still have no regrets. I love generating power rather than drawing it all from coal and natural gas burning plants.
