Once battery and solar panels are selected, the different scenarios for distribution of power generated from solar panels to battery and different loads should be considered. The different cases that can arise are:

* '''Solar panel generating power and battery discharged:''' Power generated can be used to cater to the loads and charge battery by the remaining power.

* '''Solar panel not generating and battery is charged:''' Depending on the level of discharge the number of loads can be determined that are to be turned on.

Now the generated power should be taken to the different loads depending on their needs i.e. voltage requirements etc. Voltage and current regulators can be used to provide the required voltage and current by the load i.e. converting the high or low voltage or current to the levels required by the load. A suitable way is to use a voltage regulator and current limiter in series so that both voltage and current are in the controlled ranges. Different mechanisms to do this with high efficiencies are present that can be selected on priority basis:

* '''Switching Regulators:''' Switching regulators rapidly switches a series element on and off. They can operate with both synchronous and non-synchronous switches (FETs). These devices store the input energy temporarily and then releasing that energy to the output at a different voltage level. The switch’s duty cycle sets the amount of charge transferred to the load. Some examples of switching voltage regulators are:
