  1. Hello.
    you address lights ,water pump TV use.
    I’d like to know can i charge mobile phone and lights?

    1. Hi Mary Carmel,
      All the options outlined would be fine for recharging your phone as this is not something that would place a huge demand power wise on the battery to which the solar panel is connected.
