Description

Circuit schematic like in Figure 1 above is Circuit Schematic 6V Solar Charge Shunt Regulator. According Electroschematics site describe that A shunt regulator technique may be effectively employed in regulating the charging voltage of a lead-acid battery. Although it has a practical power limitation (< 20W or so), it has the notable advantage of being an LDO (low dropout) regulator (zero voltage dropout in this case) - this is in contrast with the typical series regulator that often has a dropout voltage in the order of 1 to 3V.
Note that 6V solar panels often have minimal voltage headroom that tends to make it difficult to obtain the full charge voltage of 7.2V.

The shunt regulator is connected across the load rather than in series with the load. It regulates the voltage by shunting excess current away from the solar panel. In order for a shunt regulator to function, it must work against high source resistance – in this case, the solar panel is ideal, having a very high source resistance. Shunt regulators tend to be less efficient than series regulators because they dissipate the most power when the output is at minimum – however, in this case the power dissipated is the excess solar panel power that would be otherwise unused.
