LOL
I see your concern but its multiple reasons. 1. Our power grid is very unreliable, I am without power for weeks/months every year in the hurricane season.
2. The power company here adds 'fuel charges' that fluctuate monthly, resulting in powerbills varying from $400 to sometimes $800 a month, for a 3 bed room house, without running a/c.
I changed my stove, dryer and water heater to propane, this helped a lot already. I am selling my house and building a cottage in a remote area, I plan to take my solar set up with me eventually.
No they dont. It is illegal to produce power for others than your own use and feed it back to the grid.
I understand. So if I scale it down to just lights, tv and fridge I dont need as much panels then?
East Penn 6 Volt Golf Cart Battery - Gp GC2 from carquest -- is this any good?

STOP NOW.
Taking anything off-grid when you have the grid available is just plain foolish. Why on earth would you want to pay 5 to 10 times more for electricity the rest of your life? That is just plain ignorant.Leave a comment:

This is so true. I notice some youtubers have solar set ups that dont make any sense or are totally opposite of what I have read here or on other solar forums.
Ok, update.. I have ordered 2x 285w panels from Sunelec in miami, they have good prices especially if you pick it up in person.
I will go with a 24 V system, a 60 Amp mppt charge controller and a 2500 pure sine wave inverter for now.
(my starting goal is to run some fans, phone chargers, computer, tv, maybe some lights this year.
Eventually after I order more panels I want my 7 amp fridge and maybe washer to be on it)
Question 1: Now I am guessing I need 4x 6V batteries in series before I hook anything up?
Question 2: Does it make sense buying a larger pure sine inverter now, seeing that I want more stuff on it in the near future (end 2013-2014) and what size?
3: My other remaining questions are the wire sizes. I want to keep an eye on my brother in law electrician's decisions on wire sizes.
-wire size from panels to charge controller? (25 feet long)
-wire size from charge controller to batteries? (on same wall)
-wire size from batteries to inverter? (on same wall)
Any input is GREATLY appreciated. My power bill is around $500 without running A/c. Welcome to the Bahamas! :/
Why are you thinking of going off grid?
Does the local government allow grid tie and net metering?
If they allow this stop the battery quest and do a grid tie. for what you will spend you can purchase twice as much as much solar and save 2-3 times what you would be saving on the electric bill alone not counting battery replacement.Leave a comment:

I hope that you rely a lot more on what you learn here than what you see on YouTube. One of the problems that is that unless you already understand the topic you cannot distinguish the good stuff (which there is!) from the 95+% BS.Leave a comment:

Very rough rule of thumb (I think that there's a chart on here somewhere)
up to 1000W Inverter on 12V
up to 2000W inverter on 24VLeave a comment:

Do not even think about a PWM controller. PWM is for toys like a dildo.
Here is the deal. To get the full 60 amps out of a PWM Charge controller you have to use very expensive battery panels to the tune of 1100 watts. Battery panels will cost you around $3/watt. If you use less expensive Grid tied panels at around $1 to $2/watt all it takes is 700 to 800 watts to get the same 60 amps. Run that equation through the protein calculator. Otherwise use a calculator made from sand if you lack a protein calculator. Let the girls charge their toys with PWM. Men use MPPT.Leave a comment:

All I want is my 3 bedroom ceiling fans on it and my fridge, and my washing machine ocasionally.
No airconditioning. I already have a propane waterheater and propane stove.
I want my bank to be 4 x 6v batteries by this winter. This year 4x145 dmsolar panels. Next year 4 more.
Do you think because we have such a pletera of sunshine here, my house is fully exposed, I can get away with a xantrex c60 PWM for now?
Or should I stop being a pussy and just get the 60a MPPT one time and done.Leave a comment:
