Yes, I have read those adds, you get no more than what most already have learned in high school. most kits are a assembly of bits and pieces of free informations gathered on the internet. google solar energy disscussion forum and find out for yourself.

Solar panels are the way to go if you want to be off the grid. I used a gasoline generator at my house for two years, and it cost me $300.00 in fuel each month, (the electric service provider was cheaper than the generator). I used the generator ten hours a day.A neighbor had Solar panels installed in her back yard that were sufficient to warm and cool her 1,150 square foot home year round. and she has no Electric Bill each month....Go with a well known solar panel manufacturer if you buy a system, and have a Reputable service company do the installation. You won't regret it.
