== Monitoring and Regulation ==
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 switch 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:[[File:Reg1.png|frame|left]][[File:Reg2.png|frame|center]]<br \>
* '''Linear Regulators:''' Linear regulators use linear, non-switching techniques to regulate the voltage output from the power supply. The regulator’s resistance varies according to the load and results in a constant output voltage. <br \>
Overall linear regulators are simple to use, low cost and less noisy as compared to switching regulators but switching regulators are more efficient and have a high voltage range of operation.<br \> <br \>
