  • Project design

    Hey guys, I have to do a project in which i am in a group that has been assigned the task to bring solar energy to kabala, sierre leone. The task is to create a solar energy system in which it is possible to charge up to 20 5A-hr 12V rechargeable batteries in 8 hours. Can someone inform me as to what would be the best solar energy system to use? thanks

    What type of batteries.
    The issue here is going to be if all will be connected at the same time or will it be a floating number of batteries?
