So after all that we are back to where we were three years ago when I found out that 210w was perfect for us. Got to stop fixing things that ain't broke!

Always wondered why you switched from that setup.

Money. In 2011 started with an 80w ($350) and a 130w ($450) and the 210w was perfect for us. Then I learned prices were dropping and wished I had not bought the 80. Lucky for me the dealer took it back so I had just the 130.

In 2012 I tried the 130 in the floppy type contraption and that was almost enough solar. But then I found the guy here who was selling panels for $1.20 a watt so I got a 120w and now was back to 250w. Perfect again. That is where I should have stayed.

But then this guy dropped to 1.08 a watt and would take back the 120 I just bought so I got two 100s. That was my 2013 set of 330w which was too much solar. I didn't want to sell the 130 and take a bath on that, but a camper here wanted my two 100s so I sold them and was back to 130. I was going to get a 120 at $1.08 but the dealer went out of business before I could.

Then last Fall I saw that the dealer who sold me the panels in 2011 was now selling 230w panels for $275 and Jim found the Eco-W for $102 so I did that. Now I had 360w! Way too much. However now time has passed I don't feel so bad taking a bath on the 130w (three years old) (which she is now selling new for $260 instead of $450 back then.)

So I just sold the 130 and some Vector chargers I no longer need to a camper who needs them and am not out too much, and here I am---your new MPPT man!

Now I need to find a likely newbie who will take the 230 and Eco-W for say $375 and now the other dealer is back in business, I could get two 120s for say $300 and use the Solar30 I kept. Then I would be a proper civilized PWM man again with a perfect 240w set. :)

Maybe I should just get a table at the Flea Market and buy and sell solar stuff ?
