I guess you my orientations are obvious

Solar is the way to go!
It does require both solar panels and a battery to make up a complete backup power supply. I installed the first StorEdge/LG battery system in the State in Sandwich during late August and within a month the clients had to weather a 3 day power outage. Their StorEdge inverter immediately switched their essential loads over to the LG battery. Essential loads are usually water, heat, and refrigeration but in their case the most appreciated one seemed to be their internet connection.
Readers of this forum would probably be most interested in the security of powering for cameras and dock circulators, but there is also a financial incentive to adding energy storage. The excess power generated by the solar array during a summer day would be stored in the battery and used in your home later during the evening. This is called self consumption. The inverter will know to draw the battery down first to power your evening loads before beginning to buy power from utility company. It only amounts to a savings of a couple of bucks per day but it does add up over time. Here's a link to an excellent short video that explains how a StorEdge system works The LG RESU battery has 9.8 kWh per day energy capacity and comes with a ten year warranty.
While it is necessary to have both a battery and solar panels to be able to be fully independent of grid power, you need not have a huge array of panels if your only interest is powering your essential loads. More panels does mean more usable power for your home and a much greater utility bill savings, but it would only take 6 to maintain the battery well enough to keep your circulator running consistently during a long power outage.
