I live in GA and rule of thumb is average 5 hours of sun per day. more in summer and less in winter. 16x 410w x 5 is the per day in watts I expecte to get with this.The sun hit about 1000w per meter square at equator. Best human made can get is over 40%. Best human use is about 30%. Best on sale is about 20%.
Perfer clear or white bottom layers for more efficiency. Heat cause the panel to lose efficiency and died early. 2 sides is perfer in northern places. you will get more efficiency due to snow, or mist, or haze (bad weathers). but less efficiency during good weather due to heating.
The most worrying thing is fire. Who would pay if your house burn down. The next is longevity. Usually, solar panel lose about 1 percent efficiency per year. So when they get to 20 years (80% efficiency) they call it end of life.
LFP battery is awesome for home charging. it has more cycle than lithium ion and more cycle when charge to 100%. it is better use as a home battery vs car battery. Just make sure to keep it cool. slower charge at a cooler temperature give your battery more cycle. highly likely your ac is running when the solar get the most action. 6x 100ahx 50v is 30kw. 16x 410w x 5h is about 30kw. (is my math right?) so it takes at least 5h to charge or 0.2C using the panels.
my cost is 0.11 per kw. 30 kw is 3.30 dollars per day. 7,500 / 3.3 is about 2500 days or about 8 to 9 years rod. faster if your electricity cost is higher or you have variable pricing. if you drive tesla 4m/kw, it is 120 miles free charge per day. gas price about $3 per 30 miles for smaller car at cheaper state. so you save about $12 in gas price per day or roi in 600 days or 2 years.

I reached out to Eco-worthy regarding sale tax exemption in Florida. They said it is set by eBay and suggested me to contact eBay to fix this.
Is it normal not to have any model numbers for any of these products? I would think you'd want datasheets on all of these products. For example, are the panels bifacial?

Why would you?
