Solar power setup for FT-897 and FT-817

[KC8CAY]

Hello all,
I have been doing some research and would like to see if my following setup would work for an FT-897 and FD-817.

10-15w solar panel
do not know what amperage charge controller I would need
20aH battery

Thoughts? The main problem I am running into is to see what size charge controller I would need. Any help would be appreciated.

5 amp would do it.
I have 2 x 124 watt panels with a 30 amp controller. Been working for over 4 years now with no problems.
