Yes, it is different - extrapolation extremus.
Regardless, the basic structure must remain cast-in-concrete. Watts are watts, dollars are dollars, and hauling energy sources and storage is the same in Tibet as it is in Timbuktu.
"What? Me RV where it's hot and have no hookups? I have people that do that for me" isn't a valid condition to impart on subjects. Understanding valid components of complex energy systems means learning then deciding if a particular regimen or product is right for you. Your neighbor can't decide, nor can a salesman (but he'll warp reality to the point of becoming an inverse matrix, in an attempt).
Some folks could care less what -anything- in their life, costs. Just slap it on their American Express Black Card. What are the odds that anyone at all on this forum fits that criteria?
Hard, ice-cold information and numbers deduced into a practical/impractical for-me format for a decision is impossible to surpass.
What "works-for-me" may work as well for perhaps as much as 1% of the general population. The problems arise when the Herb Tarlek syndrome arises and "persuasiveness" attempts to influence folks too lazy to try and learn the basics.
