OK, so you've decided to go solar for an emergency back up system. Well, there are many things you will need to know. First of all, it will cost money and lots of it. There are many many factors that need to be addressed before you even begin to go with solar. IF your only wanting a small back up system for grid failure, you will be much better off and much cheaper by just getting a decent generator and a couple of long and heavy extension cords. You can get a fairly good generator at the nearest Home Depot or Lowes for around 6-800.00 and a couple of good cords for around 50.00 ea. To get the same power from solar , you would be looking at several thousand dollars minimum. Now, if you plan to live off grid, or even grid tied it does get a little better in value for the dollar, but not by much. Grid tie systems can cost you enough that it can take up to 20 years to break even. Where if like me, you had no choice in the matter but to go solar as there was and still is no power lines anywhere close, then money becomes a mute point at best. For most of us around my neck of the woods, living off grid on solar, we never discuss how much it costs, but rather does it all work as intended, and if not, what do we need to make it better. ` So, if your wanting to go "solar" then this is the right place for you to start, as we will all try and steer you in the right direction, rather then to the nearest solar company where you will be tagged and bagged like so much fresh meat. Which is what you will be. -Many many of the so called solar salesmen are just that, salesmen. Last week they may have been selling cars or sham-wow's on tv. It is only a job to them and a lot of them are paid on commission. The more they can sell you, the more they make. So, after all of this, if your still interested in solar living, ask away !
