anyone know about doing something like this. My electric co-op is being un coop about a facility charge of 15.00 per meter. I am thinking solar for the 110 volt in the garage, to save this and the electric bill.

Also would need something for the pond, small pump filter combination.

Danny,
check out www.homepower.com, great mag, has anything and everthing to do with alternative power. mother earth also has some good stuff.

Give us some more info on what you plan on doing with the electricity in the garage. ie just lights, lights and a few light power tools, or big stuff like air compressors ?

Cost will be VERY high to set up a useable higher powered solar /110vac system. If you just want lights and a small pump go with a solar/12vdc system, still not cheap though. If you are thinking of setting up a solar electric system to run powertools/welders, etc., think many thousands of dollars. And you do have the maintenance cost of replacing all the batteries perodically.
A solar system for just lights will not be too high in cost, might get by with 200.00 or so.

Danny, you will likely spend THOU$AND$ of dollars on the solar set up. Solar panels generate DC, you will need to store that in batteries, which are very expensive and take up a lot of room, and then you will need a large inverter to turn it into AC. I looked at going off grid on my house when I built it. It is not cost competitive if you have easy access to utilities.

Now if you want to keep the electric meter, so you stay on the grid, then you can skip the expense of the batteries, and run power from your panels to the inverter and then backfeed your utility. In theory you can spin the meter backwards and the utility will buy your excess energy. Problem with that is they buy at "wholesale" and they sell it to you at "retail" so you will find the payback will take FOREVER.

Hate to sound like such a pessimist about this, but it is the reality for most folks who already have utility service. Now if you are miles away from the grid, then things figure differently. But you are already hooked up.

Why do you need a second meter? Is it too far to run a sub panel off the house?

Thanks Guys,

I will check into the links etc. Yes it is for lights and power tools. I would not put a lot of $$ into this, as 15.00 a month would take forever to get my value out of it. My electric at the barn is that way because of the way my house electric is setup, and no way really to get a feed to barn without tearing up drive and concrete. Thought of doing just that, but have since decided not really worth it.

Comes down to the electric company having a monopoly on us and we have no choice but to use them or do without. Would like to see some action by local government to put that back in our hands with a second or third choice.

Danny, like you I got into a tiff with the utility company a few years back and looked into the possibility of going off grid. I did a lot of work on solar, wind generators and combinations of the two. The short answer is that I wouldn't have lived long enough to even get a fraction of the initial outlay back. I was so T'd off at them that I even looked into the possibilty of getting a seperate full time diesel or natural gas generator installed. Unfortunately the power companies have done their economics too well. If you are already hooked up, it's just not worthwhile trying to cut them off.

Many if not most simply credit you the power, you do not sell it to the utility. If you were ahead on the wattage and actually gave back to the utility company more then you used, you simply get a credit of the number of watts you generated and typically will use those credits in the summer with AC costs. You don't have to be tied to the utility, but in some areas, you do get credit rebates on your purchase. If you look at the link provided in one of the first posts, it does a good job of explaining how solar works.

Same problem when I put in my shop. Had to cross a three car driveway or go around the whole house in a trench.

I got electricity to the shop by going UP from the service entrance into the attic, across the house (in the attic) and then down, on the outside of a wall (tucked into a corner) in a 2" conduit that then went into a trench to the shop.

It's easier than you think, but you do have to be confortable with working in the breaker panel box.

You can tunnel under a driveway with PVC and a garden hose pretty easily. Even if you lay out $150.00 extra for wire to run the long way around or through the house, you'll get that back in 10 months time in savings. How far is it to the garage from the service panel in the house, how many amps service does your house have and how many amps do you need to pull in the garage?
