Wow way cool, we currently live off grid and our main source of power is solar. The cost has come down tremendously. The first 100 watt panels I bought a number of years ago cost 500 dollars or around 5 dollars a watt. Now you can buy them for around $120 or $1.20 . You can save a ton by installing a system yourself, it is very basic electrical wiring.
I smile now for more than one reason when the sun shines.
