And that would cause problems. So can you reduce your solar panel voltage? The easiest way you can reduce your Solar Panel’s Voltage is by using either an MPPT Charge Controller or a Step-Down Converter (aka Buck Converter). Other solutions are to use resistors or modify the solar cells’ connections via the junction box.
Before planning to reduce your solar panel you have to make sure your panel is performing well. If it is broken and producing low voltage you’ll have problems in the long run. First, perform an Open Circuit Voltage Test. Step 5: And just like that take the positive lead and connect it to the Positive Terminal. Read the voltage.
Consider using a non-optimal tilt for your panels. This will reduce their peak voltage without circuitry. Consider active monitoring of the voltage, ie, microcontroller + voltage measurement + relay + resistor/diode. Which is pretty much adding your own input over-voltage protection, without constant loss of resistors or diodes.
The analog solar cell voltage stabilizer depicted in the circuit below regulates the output current such that the input voltage U_I U I stays at a fixed voltage programmed via the voltage divider. This lets us then choose an input voltage close to the MPP of the solar cell.
Since the solar panel's maximum Voc (50.882) could be slightly higher, how can I reduce it to be below 48V? Would any of below solutions work and practical, or are there better alternatives? Use a set of 10A10 rectifier diodes in series. That uses the rectifier diode's forward voltage of 0.6-1V x 5 to drop the voltage.
The resistor is useless. Your solar panel already has a voltage decreasing when current increases (that is, it is not an ideal voltage source,) and the maximum current your small panel produces should be no issue at all for the capacitor. There is no reason to dissipate power as heat The 1N4148 diode you use is not adapted for your application.
