With reference to the suggested circuit for a solar panel voltage regulator, it is apparent that it is designed to meet our specifications while utilizing relatively common components. The centerpiece of the whole setup is a single integrated circuit (IC) called LM 338, which is in charge of enforcing the necessary voltage limits all by itself.
The zener doesn''t "short" the power source (panel), it simply limits the terminal voltage to a fixed value. The zener will be dissipating power equal to the zener voltage multiplied by whatever current the panel can deliver at that voltage (minus whatever current the load is drawing, of course), so it needs to have a suitable power rating.
Parts List for the low drop solar panel charger circuit: Q1, Q2 = 2N3906 or the majority of small signal PNP. Q3 = 2N3904 or the majority of small signal NPN. Talking
Circuit must have adjustable voltage regulator, so Variable voltage regulator LM317 is selected. Here LM317 can produce a voltage from 1.25 to 37 volts maximum and maximum current of 1.5 Amps. Adjustable Voltage regulator has typical voltage drop of 2 V-2.5V .So Solar panel is selected such that it has more voltage than the load.
