LiPo Smart Charger

I’m looking for a smart charger for LiPo cells that can run from a solar panel.  I’ve heard that the combination is incompatible because of fluctuations in output from the solar panel.  Is this true?  If so, is a workaround a larger panel?

There are a lot of solar to li-ion battery charger ICs. You might get one on a breakout board, like the following: www.ladyada.net/make/solarlipo

I made a small solar powered solar tracker that has a similar IC, and charges 2 li-ion batteries to about 8.0 volts. Works well, in operation over a year now.
