The batteries will be charged by means of ten small solar cells panels that i have designed. I need one prototype to test my charging rate of the solar cells. Thank you, David

we are a group of three engineers from three domains of expertise , as in Software hardware and mechanical and are working for a firm under product development and design division in melsungen Germany with expertise and understanding in both hardware and software domains we excel in such kind of jobs as this is our day job as well :) what I see as a project stand point would classify this as a sub system to an already existing multistage system hence would like to divide this into following stages : stage 1 : requirement understanding and complete understanding of the actual work stage 2 : design documents , and schematics delivery stage 3: final delivery of the GERBER/PCB files Stage 4 (if necessary) i can also build the PCB and assemble components for you , but in that case the exact amount for all the components and the PCB will be changed separately and has to be Bourne by the client(you) this would eventually lead to smooth operation and completion of your project thanks, Abhishek
