Solar Power for Public Health - used 65-80W solar panel

Hello,
I am a Canadian PhD student doing public health work in rural Panama.  Specifically I am looking at the interaction between parasite infection and malnutrition and how that changes with the delivery of a government health and development program.  Some of the parasite infections that I will be diagnosing need to be examined as soon as possible after sample collection so I will be setting up a laboratory in one of the community health posts.  The problem is that these do not have power.  I have found microscopes that work on rechargeable batteries with LED lights however I will need to charge these overnight for the next day's work. I believe that solar energy could provide the answer however I am working under a tight budget.   

I am looking for a used/donated 65-80 W solar panel and a charge regulator to charge the batteries for 3 microscopes.

Any help that can be provided would be greatly appreciated!!

Thank you,
