I'm looking at the websites and prices and I want to know what is the best way to do this on the cheap so we can set ourselves up to expand the array later. I'm thinking of doing it this way:

1. By a DC/AC inverter

2. Buy a panel

3. Self Install it to grid.

4. Buy battery

From there save money and buy panels and accessories progressively.

You might want to check this out too...
If you do a search on google for "free solar panels" quite a bit comes up on how to get free/cheap used panels...

Here's a couple of links:

Haven't tried any of this myself but it's worth a shot!

Don't solar panels become ineffective after 10 years or so?

Nope.

Most panels that were made in the 70's are still chugging along, having lost at most about 30-40% of their production ability.

You can get individual solar cells on Ebay (http://shop.ebay.com/?_from=R40&_trksid=m38.l1313&_nkw=solar+cell&_sacat=See-All-Categories) and wire 36 of them in series to make a 18volt panel. They are slightly chipped but this doesn't effect overall performance. It's about $150 for a set of 36. Then you can make your own panel using this Instructable (http://www.instructables.com/id/Build_a_60_Watt_Solar_Panel/).

This will make a 60 watt panel for about $250. It's not the most beautiful thing but not bad either.

60 watts? There are individual cells that are bigger than that. Sure that's note 600 watts?

one way to harness the sun using panels is using mirrors, student at whatever school, I forget which one, made a panel 10'X10' which focused the suns light to one point above the panel, the focal point got so hot they couldn't get a peice of wood to the center before it was tottally burned up, they tried metel and it melted a solid steel beam in seconds
