Called local place, didnt like his opinion on solar power (Bias).
Went online did a lot of homework, think I have it about figured out.
At current usage.
27.7KW per day
1.15 KW per hour
So if we want to run 100% solar 8 monthes out of the year we get 10 hours a day. ((Assuming panels get all that light)
So an excess of 14 hours is required or 16.1 KW (16.1 / 10 = 1.61 KW needed in excess a hour)
So in total we need 2.76 KW per hour of sun or 14 panels
Panels are 250w for 400$ (Counting them as 200 because your never suppose to expect 100%)
Batteries are 12vh 125ah for 250$
5600$ in panels and at least 12 hours of battery life or 12/1.5= 8 batteries or 12,000 watts.
2000$ batteries
400$ inverter setup
400$ charger setup
Material 500$ (Ball park)
8,900$
This will save us 200$ month in electrical at current rates for 8 monthes so it will save around 1,600$ yearly.
A 5.5625 year turn around.
You will need 2000$ in batteries every 8 years.
So in a 20 (Panel "life") year run period you will spend $15,100 but save 32,000$ a overall savings of $16900.
5600$ panels
5000$ batteries (Assuming 2.5 replacements)
2000$ inverters (Assuming 4 replacements)
2000$ chargers (Assuming 4 replacements)
500$ materials
So you save approximently 845$ a year or 70$ a month for 20 years. Including the 4 winter off monthes worth of sunshine it came out to about 9$ extra a month saved.
If anyone is good at solar/electrical your opinion would be appreciated. Please keep this far from political, this is about saving $$$.
I think I am pretty much going to get a couple panel setup just for summer, and see how much I can I pull/save with our 20 hour days, I just can't justify the upfront cost to save so little a month.
