si solar cell Customers Reviews

  • Low current

    posted by mihaim1980

    It's cheap and the wires are easy to solder on it. It's very small, you can put it everywhere. You can use it as a light sensor using a microncontroller.It's easy to use it. Just drop it in the sun light and it produce voltage.
    Don't buy it!The voltage is around: 2,2VAnd the curent is: 0A!!!!
    It's good bu you must buy a lot to make it usefull! I like them because are very small and you can use it for small application like lamps or another things
  • ok cell, for 10 $

    Very good prizing, the polarity of the cell is marked so it's ok (you'll need a welder 30 watts it's ok, even too much) its ok for doing small toys, power for clocks, and small experiments
    The real voltaje it's hard to measure, it changes depending on the sun. I measured 4volts in a cloudy day and near 6 volts in a sunny day.
    The short cut intensity its between 5mA (cloudy) and 46mA (it can arrive to 50) depending again on the sun, its far away from the 80mA on the announcement
    it arrived very late because of the chinese new year so i understand that
  • Nice price, but...

    Good price, smaller than expected. Tabs on the back are easy to solder to. Comes packaged nicely in individual plastic 'ziplock' bags.
    Nice for the money if you don't really need 18mA, or 9mA, but can get away with 1-2mA.

    It's quite small, and easy to use. It gives 5V, just like it says in description. It has no appreciable weight, and it's quite thin.
    Don't have any other thoughts. It's a good product.
    It's a good product, it does what it's supposed to do: give 5,x V when de sun lights. Even if the light is not shinning, you get over 3,x volt when you test it. Satisfied.

    a small photovoltaic cell which clearly indicate which is the positive and which negative, small size and light weight.
    nothing more remarkable than it looks.
    is a good product to enter the world of photovoltaic cells, however, if small enough voltage to produce limited use except for simple circuits.
