Should I add an extra panel?

Hi 

I have recently installed a 5Kw LuxPower inverter and a 5Kw Greenrich battery. I have 5 JA 455 w mono Perc panels.

1. Firstly how much power can I expect from these panels on a good sunny day? At the moment they are producing around 1700 to 2000 w. In the past 16 days my consumption has slightly exceeded solar power output eg yesterday - solar production 8.1 Kw  and consumption 9.3Kw. Had 10 days out of 16 slightly exceeding consumption. In the morning around  10 - 10.30 am the battery is fully charged and I start using only solar power. Then in the evening after sundown I use battery power. The lowest battery power was down to 14% after 3 days of rain and outages. At the moment I am running 2 fridges, LED lights, microwave, air fryer, TV, computer and at times the air conditioner. I try to use the air conditioner only when battery is full and tap into solar power. Even then it starts taking some power from the battery.

2. This is what I really want to know should I install another panel to make it six panels? Will it give me the extra energy I need to cover consumption?

I hope for some answers soon as the installer is coming back soon to do some cosmetic work and give me the COC. If I need to add a panel I would like him to finish the job.

Thanks
