Sunlight shining on a solar panel is used to charge a battery. Battery energy is used to charge a battery. Battery Energy is used to power a load. The load can be anything, like lights, a water pump, a propeller, a refrigerator, or a heater. Each Solar Panel can be different. The power rating and the voltage rating can be different. One Solar panel can be disabled and it won't detract from the operation of the other Solar Panels. The total current charging the battery depends on the sunlight. At low sunlights, the current, and the power is low. The most power is always delivered to the battery.

Technical:

Each Solar Panel can be different. Here is a partial list:

One can be rated at 50 watts, 12vdc. Another can be rated at 200 watts, 50vdc. The Solar Panel Voltage must be less than the charging voltage of the battery.

One Solar Panel can be disabled, whether it be by a cloud, or a blocking object like snow, and it won't detract from the operation of the other Solar Panels. The total current charging the battery depends on the sunlight. At low sunlights, the current, and the power is low. always the most power is delivered. It could be as low as 1 watt.
