Re: 5-in-1 Dual Solar Panel Possible heat reason?

I added two solar cells, one on the east side and one on the west side.  So far, it's working great.
The solar cells: http://www.amazon.com/Small-Solar-Panel-3-0V-wires/dp/B00IOUOWD4/ref=pd_sim_sbs_indust_2?ie=UTF8&refRID=19NCP3RTB6YGBJ6VR1HP
I used three 1N5819 or similar diodes, one on each cell (including the built-in one).  This keeps power from being wasted on the cells with the least sunlight on them.
