I disagree on a couple technical points, as I've researched this and have a couple electronics degrees. The bottom line is that solar requires a big initial investment, and is not reliable. The only reason I did it on the RV is so I can stay in quiet, natural areas off the grid. I have a good place on my house to mount panels, but when I start to cost things out, it is way expensive. I've not looked for a couple years, and the newer gel cell batteries may be a possibility. Maybe I'll play around and run my Ham station off solar.
We need to decide what we are going to do. If we are going solar/wind/etc. then you are right, we need to get started. Me, I'll just ride my 50 MPG motorcycle on sunny days, instead of an electric car.
