If you''re not concerned about efficiency, polycrystalline solar panels tend to be cheaper than modules with monocrystalline PV cells. However, any savings you make on price will likely be outweighed over the long term by inferior performance. Polycrystalline silicon PV cells are less expensive and time-consuming to produce.
Place the weight on top of the wire to hold it in place. The solar cell is now ready. If you hook the other ends of the wires up to a small light bulb while the cell is in direct sunlight, it will light up. If you hook them up to a voltmeter, you will be able to see how much voltage your solar cell is producing.
