3 FAQs about [Homemade photovoltaic panel controller]

How do you charge a solar panel with a voltage regulator?

Start by soldering the voltage regulator (LM317) to the PCB board or Veroboard. Connect the diodes (observe polarity). Incorporate the transistors into the circuit. Make sure all connections are secure and there are no short circuits. Attach the heat sink to the voltage regulator. Connect the charge controller to the battery and solar panel.

How does a photovoltaic system work?

As is the case with so many of these independent power-generation systems, however, a photovoltaic setup requires some means of energy storage . . . and the most popular medium now is the lead-acid battery. During the day, when sunlight is plentiful, the electricity generated by the PV panel produces chemical changes in the battery cells.

How a solar panel voltage divider circuit is implemented?

It is implemented by using two voltage divider circuits. It consists of two resistors R1=100k and R2=20k for sensing the solar panel voltage and similarly R3=100k and R4=20k for battery voltage. The output from the R1and R2 is connected to Arduino analog pin A0 and output from the R3 and R4 is connected to Arduino analog pin A1.
