Jumping in to add a little personal experience where I've been closely involved with the design and construction of 2 remote data relay sites, one only solar and the other wind and solar for which a combined solution although it's quite exposed wasn't the ultimate solution and instead we ditched the turbine and took advantage the panel mount was future proofed to be able to add a 2nd panel.
This smaller installation used 2x 195AH SLA's paralleled for 12V predominately to make use of the 12V wind turbine however we reconfigured it to a 24V system and went to only solar(2x 300W panels) and although we used a suboptimal east facing installation with clear LOS to the horizon this has proved excellent for battery recovery early in the day with peak charges approaching 20A not long after sunrise.
Both installations have a quite steady load 24/7 so the earlier the batteries a brought to a float charge state the better as even without direct sunlight on the panels late in the day there's still sufficient panel power to manage the quiescent load from the system.
The larger installation has 3x 300W panels and 4x 165AH SLA's in a series/parallel configuration for 24V however like a spiders web this installation has grown with a higher HW load on it than was the original design and even with an optimized panel orientation successive poor charge days can impact dramatically on reserve capacity where we may have to run a generator on the 4th day.
Typical daily charge is ~60AH but a couple of days of just half that may require 100+AH to get the batteries back to a float state and I've recorded 30A charge peaks on this setup.
Both installations use Morningstar Tristar 60 MPPT controllers with online data and we can monitor panel and battery voltages and charge in real time or examine 100 days of logging.
This setup has been running a few tears now and logging tells us we've captured 1MW/Hrs of charge.
What I've learnt is to overrate the solar probably 30% beyond what you think and so prevent high battery DOD to get the best service life from them. The batteries in the larger installation are hovering ~10% DOD so we don't expect a long service life from them yet logging hasn't shown they're suffering unduly yet.
