  •  Thanks for the rundown. (8+ / 0-)

    If anyone else is like me, one of the main factors holding more people back from switching over to green energy is that we expect the products will be so much more efficient even 2-3 from now.  Are companies doing anything to make upgrades easy and cheap, to reward people for getting in early?

      Hard to do with PV.   If you put PV on your roof, you don't want to go back up there a year or two later and exchange all the panels out.  Warranties are generally 25 or 30 years.  Suntech will pay you if your panels drop below the warrantied output.

      Of course, if you want to go solar, solar hot water is more cost effective but everybody wants the magic crystal.

      I live in an apartment and have a couple of small PV panels that power a couple of LED lights in my bedroom.  You can go solar one room at a time.  Those panels are five years old or more and work just fine.  If you want to go solar, go solar.  Just make sure you've become as energy efficient as possible before you size your system.

      Solar is civil defense. Video of my small scale solar experiments at solarray.
