solar cells

What's an affordable size solar cell that will actually charge 2 batteries?
  • I have the 200w renogy solar kit. It easily tops off my two group 31 AGMs after a night of using the lights and running the furnace charging the cell phones and running the laptop off an inverter. Cost was $375 and about three hours of my time to install the system.
  • I have talked with people that say they get by with 100 watts just fine and others that have 1200 watts. I think that 200 - 300 watts will work for a lot of RV's but it all depends on how many watts you use per day, how many batteries you have, what kind of controller you have, how much sun you have that day, and a few more things.
  • Bump. I'm curious too. Interesting article: http://www.gonewiththewynns.com/solar-power
  • Lots of variables. Let's begin with this:

    What kind (size) of batteries, with what kind of daily usage, and what is affordable?
