I plan to build one once I move and it will consist of the basics to power a sump pump, fridge, lights:

Panels
Charge controller
Deep cycle marine batteries
Inverter

Seems easy to DIY.. if you're lazy and want to overspend:

I know right..... Does Solar panel size matter when charging?

 

I need something which will run my Frege,freezer,lights,and if some one can give me an advice on which 6 or 12 v batteries are better for stoking energy and how many i need

 

Two 6 volt deep cycle golf cart batteries in series (=12 volt), will give you more run time than one 12 volt RV/Marine battery.
Also, you can do much better dollar for dollar, than the 45 watt Habour Freight panels.

here is a good example of a good value panel, good warranty, great supplier:

They also carry good value charge controllers.

check for their links to battery information. I'm sure you will find it quite helpfull.
They also host a web forum which I participate in:

I was going to start building a solar panel system for my aquaponics green house, but first i have to build the greenhouse, which will be started and completed in about a month. I was going to use this guys instructions on building my own
http://www.mdpub.com/solar/index.html
he also has plans to build a wind turbine, figured that might be a good idea to put on the boat to keep the batteries charged up.

 

We power our aquaponics with solar too, FYI, we are using a livewell pump so that there is no need for an inverter. Wasn't sure if you thought of that, so I figured I'd throw my two cents in.

 

Thanks solar1,how many 6v batteries i need fore my home(fridge,frizzer,lights+extra in case)and were i can by them and maybe some one can advice a frizzer and a fridge which will consume less power and voltage i was thinking maybe a mobile home appliances.

 

it depends on the watthours consumed by day and your avaliable pv watts per (panel size, quanity, etc.), it's all relative to each other. 6 volt T-105 golf cart batteries...Sam's Club, Costco, golf cart dealer, industrial batteries dealers to name a few

 

Thanks for your input...

6 Volt golf cart batteries at Sam's Club with a old battery is $88. If you don't have an old battery the core charge is $9.

 

I've been looking at these-

Amazon has some 12volt appliances too instead of relying on an inverter.

 

If looking to run pumps or light it would be good into looking into 12 volt pumps and lights (led are best). Invest in these and you will not need as much battery storage or solar panel. This will allow you also to get a smaller inverter. Issue is hen you convert from dc power to AC power you always loose some.

 

True, that's why I've been looking at everything in 12V versions. Anything that has electronics is low voltage DC, so you'd be changing 12V DC to 120V AC then back to low voltage DC again with an inverter. Less efficiency and reliability.

 

I also think that there should be a technology for solar cells which can charge our mobiles from solar energy. Most of the time I read about it in articles and business websites about solar panel progress in technology but they have discovered only solar batteries. I just want that every person on earth should use solar panel; it’s so cool and wiser.

 

Powersource 1800 Solar Generator

The Power Source 1800 is the world’s first solar powered generator that is portable, powerful and can charge many important home appliances. The Powersource 1800 Solar Generator comes with a compact solar generator that fits anywhere in your home or truck and includes 4 plug outlets so you can charge more than one device at the same time for your convenience.

$1797. for a 90 watt solar cell and a charge controler and a battery and inverter and a nice case. You have to be kidding. There is a sucker born every minute. Pops

Only way to get any large amounts of power (say enough to run refridge) is to spend large amounts of $$$. 4x8 feet of panels (32 sq ft) cost a fair amount and provide very little power. Cover you roof with $100,000 worth of solar cells and now you are talking getting off the grid.

But $100 worth of power a month for $100,000 invested is not a good deal.

It all boils down to how much having electrical power while off the grid is worth to you and how much cash your have.

Hear stories about off the grid for $500 worth of solar. It can be done, but they live like Abe Lincoln using very little electrical power.

People have no idea how great a deal $0.10 per KWH is until they try to make it themselves.

You said a mouthful right there. Solar, with a battery bank (and you don't want to go with lead-acid, because the service life is so very limited) of nickel iron cells is a viable way to run some lighting, and a few low-power fans. For anything more, you'll need a bigger plant, running some kind of alternator.

 

As a novice, myself, I'd like to know your opinion on how these flexible 124W panels measure up against the Kyocera panels you linked to?

Save yourself a bunch of money.
Buy a generator with some fuel stored to get through a week or 2 of power outages running a couple hrs./day.

Those $1800 solar generators will charge a laptop, cell ph. and a few LED lights. Other than that, forget it.
People are lead to believe they can run a frig. or A/C with those units. It won't happen for any length of time.

I admire those that are set up to live off-grid. They usually spend a lot of money to use very little energy, small refrigerators that cost several thousand dollars, etc. They have a quality system that meets their needs.

 

For the price of the 140W panel mentioned you can get 240W 24V panels. These are 24V panels so you need a charge controller that can charge 12V batteries from a 24V nominal panel. Either way, you waste about 30% of the power output potential of the panel if the charge controller does not support maximum power point tracking (MPPT) so a 140W panel is 98W and a 240W panel is 168W. Beware of cheap controllers pretending to support MPPT. For smaller systems under 500W it may be cheaper to get bigger panels than MPPT, if space permits.

 

Not sure if the OP has read Fepony's thread on the off the grid house he built. But that thread has like 600 some posts with several from Fepony on his projects, what he built, and where he got it from.

I think the title is "My 16x40 off-grid cabin",, sorry, Im sure I butchered that. Ton of info in that thread.:thumb:

 

Another one of obamass's solar companies that got 400,000,000 of the peoples money just filed for bankrup protection. that makes 3 companies I think, Maybe you can get panels for cheap.
