The MPPT will begin charging when the panels provide around 16.5V …and will need a minimum of 12.5 V rising to 15.4V to continue charging. After that condition has been met, it will continue charging as long as the PV voltage remains at least 1V higher than the Battery voltage.
Due to the target of carbon neutrality and the current energy crisis in the world, green, flexible and low-cost distributed photovoltaic power generation is a promising trend.

Panel temperature does affect voltage, as discussed in another blog. In the P-V curve, as the solar radiation decreases from 1000W/m2 to 200W/m2, the power drops proportionally – from 300W to 60W. Have a look at these I-V (Current vs Voltage) and P-V (Power vs Voltage) charts for a 305W solar panel from Trina Solar.
Since the cells have some internal resistance, they will be at a lower voltage when there is a load. You may want to consider more than the batteries for the load since you may want to operate the boat and charge the batteries at the same time.
