Every question is answered in the Off Grid Solar Panel Stickies. For example a 48 volt 800 AH battery would provide you roughly $1 per day worth of electricity of 8 Kwh and require a 4000 watt solar panel and 80-amp controller. Should not cost you a penny more than $20,000 today and $8000 every 5 years replacing 2500 pounds of batteries.

t all starts by determining how many Watt Hours you need in a day, location, and time of year use. Until you have done that, do not Pass Go. So go to the Off Grid Solar Panel sub-section and start with this one.

This question is complete nonsense. Let me ask you a question. Who is buried in Grant;s Tomb?
