Old Indian saying: “Indian build small fire, huddle close, stay warm. White man build big fire, stay warm chopping wood.” There is wisdom somewhere in there.I have a wood stove and no shortage of wood. I prefer not to spend too much time cutting up wood, so make an effort to reduce my need.
Pops, what batteries do you prefer?Sam's 6 volt golf cart batteries has two different capacities, be sure to get the larger one's, they are about $10 more. At this time I am running two strings of 4 golf cart batteries ( not Sams) for 24 volts for the 8 batteries.
<<for grid tied systems>> So much depends on where you live and what kind of incentives your local power company offers.Anyone out there have any experience with Solar Power that they can share ?
I would never limit myself to an off-grid system. It only takes a few minutes to un-tie a grid tied system, but you can't tie an un-tied system into the cash cow (grid). Everyone has their own goals, mine was free money.I would never have a grid tied system. Also smart meters are being installed in a lot of areas by the power companies.
No more than the brown outs (reduced power) and rolling black outs (temporary local shut downs) that we have now ...when the need arises. Power companies have, and have always had, the ability to "ration your use of electric power". Smart meters allow supplying full power to a hospital while they shut down service to the bowling ally across the street ...in an emergency. I'm okay with that. In an emergency, I'd rather have a fully operational hospital than a fully operational bowling ally. Without smart meters you either shut them both down or give them both power.Smart meters are a way to ration your use of electric power when the need arises .
It's the same for every state. Grid tied systems have to be isolated during a power failure or you'd kill the repairmen every time a drunk hit a power pole. You just unplug your panels from the grid tied inverters and plug them into your charge controller (post #13).A grid tied system is useless in this state with the grid off as much as it is.
Kind of obvious... there's no point in having a charge controller (post #13) if your not charging something. You keep the batteries charged with the grid tied system, ...and get paid for charging them. If the power goes down for longer than your batteries can handle, just plug your panels into the charge controller (post #13).if you don't have a battery bank you will be without electric when the grid is down.
In what conceivably possible scenario is an off grid system even remotely more reliable??? It's the same system, it's a PV panel with a cable hanging out of it. Off grid system are limited to plugging into a charge controller, grid tied systems have the option of plugging into the same charge controller or plugging into the grid (getting paid to make free money).If you spend the money for a battery bank why not just go to a more reliable off grid electric source.
Even more reason to have a grid tied system. Make money when things are going smooth so you can buy more beans and bullets to have on hand when things aren't going so smooth. Switch to batteries when the SHTF.Not everyone lives in a higher population areas with reliable grid service.
Prepare BEFORE things go bad. Get cash now, buy the stuff now that you'll need then.Be prepared or suffer.
On top of the money you save, you could be getting paid $100- $120 a month just to generate the power your using.I'm saving about $100- $120 a month.
We only get about 8" of rain a year here. ...if this wasn't the HBA I could tell you how to have the federal government pay you to install a rain water collection system.Next is a backup water supply. 5200 sq ft of roof area with 48-50 inches of rain a year.
