My headhurts....But I figured out. (roughly) that if I have 100sq ft or 14,400 inch2 of solar panels, that ='s
.35 kwh or 5040 watt hours per day for 5 kwh. At a cost of 5500.00 for panels, not including batteries, invertors or other fun stuff. I was hoping to achieve 10kwh for the future new cabin. Now to go to each appliance with kill-a-watt meter to see if this will work.
Then after that how many batteries I need for surges and sunless days.
Ok I can put my shoes back on, the counting has stopped for today.
So, does this sound right or am I way off?
To be completely off grid?
Forget about the sq inches, that makes my head hurt too. Start with the power required. The Kill-A-Watt is good for things already owned. The rest can be estimated by looking up watts used. (When I Kill-A-Watted several things I found some used noticably less than the power rating (my laptop for example). Nothing I tested used more than the label rating.
Once you have that data download the tool HERE (http://countryplans.com/smf/index.php?topic=8192.0).
And then ask questions about what doesn't make sense or is difficult to understand.
The train will get to Chicago 56 minutes before Jimmy gets to Baton Rouge in his truck. What do i win? d*

Crimoney, Stinky.... I'd hate to see you having a power surge....
Thanks MtnDon....As for the other two... :P
hehehehe....Must admit at one point that I was going to have a stroke.
:-X Sometimes it is better if I just refrain from commenting..... [ouch]
here is a good on-line calculator
it is not the square footage, per se, but the watts put out by the specific panel
