All fair points. This is particularly true in the case of most of the solar systems around me, all of which are barely adequate for the homes where they are installed. This is one aspect of the solar industry nobody talks about. The other day I saw a report about this guy who was charged $50K for the installation of a dozen panels. I designed and installed my own system. I regularly supply 8 to 9 kW to the grid (peak, of course). When the grid has gone down, I can turn on the system and supply the entire house without any issues at all, even without a battery. I will probably install batteries sometime next year. The cost is still high. I need to wait until the ROI makes sense. My ultimate goal is to completely disconnect from the grid if possible. My guess is that I'll probably have to double my system size in order to be able to achieve this.
