First connect the positive and negative wires from the output end of thesolar panel, then connect them to another lamp.
A solar panel can be connected to 3 lights. You can run multiple bulbs in series or parallel depending on the photovoltaic panel's output capabilities, voltage or current. For example, photovoltaic panels produce 24 volts. If the bulbs are 12 volts, you can connect two of them in series then connect them to the photovoltaic panel. If the photovoltaic output current is 2 amps and the bulb operating current is 1 amp, the two bulbs can be connected in parallel.
Principle of energy production
Sunlight shines on the p-n junction of the semiconductor to form new hole-electron pairs under the action of the electric field of the p-n junction. holes Electrons circulatefrom region p to region n and electrons flow from region n to region p When the circuit is connected, a current is formed. This is how photovoltaic solar cells work.
Solar power generation methods There are two solar power generation methods: one is the light-heat-electricity conversion method and the other is the light-direct conversion method. electricity.
(1) The light-heat-electricity conversion method uses thermal energy generated by solar radiation to produce electricity. Generally, a solar collector converts the absorbed thermal energy into steam as the working fluid and then drives it away. a steam turbine to produce electricity. The first process is a process of converting light into heat; the second process is a process of converting heat into electricity.
(2) The direct conversion method of theLight to electricity uses the photoelectric effect to directly convert solar radiation energy into electrical energy. The basic device for converting light into electricity is the solar cell.
A solar cell is a device that directly converts solar energy into electrical energy through the photovoltaic effect. When the sun shines on the photodiode, the photodiode converts solar energy into electricity. . Light energy is transformed into electrical energy, creating an electric current. When many batteries are connected in series or parallel, a solar cell array with relatively large output power can be formed.
