Please help me with solar setup
I have been reading a lot about solar on here and finally decided to take the plunge or come to the dark side as some would say. Sunny side makes more sense, but whatever. :) We do not use a lot of...

Even with new 24v panels my MPPT systems come in under $500.
He wants 2*12V panels, these small systems are more expensive per watt.
Yes, it is possible to source the components - some old, some new, with some compromises in performance and wiring under $500 for 2*24 panels. Your latest TS60 system is probably over $1,200.
BFL - there is nothing about Absorption in the P30L manual.
My new system isn't much larger than the three smaller systems were, 720w vs 750w. I would have mounted the twin 245w mono's but they showed their true colors when the clouds rolled in so I decided to get three polys and fill the roof.
Now when I said you wouldn't get enough difference to spend the money on MPPT, I was talking the difference between the small PWM and the Eco-W, not some aging big brand PWM vs other MPPT in that price range. The newer Tracer MPPTs compete with that price, are completely adjustable and have both remote display and temperature compensation. Even the Eco-w could handle the two 140w panels in series but without the remotes. I know of one running two 150w panels long term, it hasn't died yet.
I don't have any "do this" answers, just options. It took me three years to work it all out, twice I thought I had it but I wanted to do things people said I couldn't. Now I can.
