Hello, I am very new but curious to The whole power wall scene. I live in Florida down south recently hit by hurricane Irma and have been without power for 6 days now. So right now all I dream of is solar and stored electricity lol. The main purpose of this thread will be to determine cost of starting project and how long will the return on investment take place.
These are some of my details.
Live in Florida east coast.
Cost of kWh is $.12
I use about 66 kWhaverage daily(because I'm a American slob ?)
About 40kwh is used while sun is not out and 25kwh is used while sun is out.
Monthly bill for electricity is about $225-250 a month during summer and about $170-200 during winter.
Questions:
1. How many solar pannels (recommend watt panels ) would I need to have at least 80%-90% off grid for house use and battery backup for my daily use.
2.how many 18650 cells would I need granted I am getting them at $1-1.50 per celland at 2300-2400 mah.
3. What recommended wires/gauge needed to series these properly and safely.
4. What inverts, converts, wiring, BMs, etcany other components needed to have this all grid tied and costs of those items.
I guesstimated in a 30pannel 250w solar system @ about $7500 pannels only. 7kwh system and about 5,000 cells in that 2300-2400 range for about another $7500 batteries only. Not including all the other important components, let's just say for the right quality equipment another $5000 putting my total project at 20000 my return on investment is about 7-8 years ?
Is it worth it and what's the life expectancy of the cells and panels?
If anyone was to help I bless you considering I'm very vulnerable right now sitting with no power for so long.
Thanks
