However, there is no one-size-fits-all solution; each installation needs to be assessed individually.

Is a water heater better than a solar heater?
For months when there is more sunshine available, a standard electric water heater with heating elements somewhat optimized for the V-mmp / I-mmp of the panels & configuration running it DC can be cheaper and more effective hot water than traditional solar thermal system (cheaper hardware up front, and more reliable.) Some off-gridders going this route select and configure the panels such that a standard 240VAC/4500W heater element runs near the optimal V-mmp / I-mmp range much of the time. The controls can be dead simple (though I would assume there are DC-optmizers that do much better than the totally dumb approach), along with something to interrupt power when the tank hits 175-180F (most are rated for 180F max), and a thermostatic mixing valve on the output to prevent scalding works. I've not personally dug into what it takes to design and optimize those systems, but am aware that it's now "a thing".
Can you use a tank type water heater as a storage tank?
Sure, it makes sense: you’re basically wanting to use a tank-type electric water heater as extra storage capacity when your “real” batteries are full. The water heater in this case is acting somewhat like additional battery capacity that can soak up extra PV output.
Can a maximum power point tracker drive a water heater?
There may be maximum power point trackers out there capable of driving a range of water heater elements varying the actual voltage at the heater element in response to the immediate max power point of the panels as conditions vary, but I don't know of an existing product specific to water heaters. Maybe some of the off-grid blogs will have insight into optimizing the power for this application. This guy's thermal maximum power tracker solution addresses those issues, but isn't designed to match or optimize for a fixed resistance such as a water heater element:
Can you use a relay to energize a water heater?
If you have a charge controller with some kind of “batteries full” output signal, you could drive a relay to energize the water heater so that it would start using electricity after your batteries are fully charged. You’d need to be sure it will shut off when PV output drops back down too.
