Solar panel battery charge

I have 300 watts on my roof. 2x 140watt panels, and a 20 watt panel. They are located front, mid, and rear of the roof. This allows me to get some sunlight on at least one of the bigger panels in most areas where i camp. On the island here where i live there are many tall trees or high mountains and having full sun such as an open field does not really happen. This way I usually can get ~150watts of charging for 5hrs or so, sometimes even more if im in a bit more sunny spot. My power usage is considered very light, my solar panel wattage would be way overkill but i factored in only 1/2 of it ever working at one time. I am extremely happy with solar and so is my friend who i helped install his system. Neither of us ever use a generator during spring/summer even on 10+ day trips. Our families are outdoor campers, there is no tv watching/indoor shenanigans eating power up other then a radio, sensors, fridge and charging kids electric quad batteries. I also have 2 6v batteries (trojan)
