If you look at the volts/amps/watts graph in the data sheet of a solar panel - www.suntech-power.com, http://shangde.fanyacdn.com/imglibs/files/iec_stp325_vfw(mc4_325_320_315).pdf - you will see that, as the current load on the panel is increased, the watts obtained increases to a maximum and then falls away. Maximum watts occurs at about the same voltage for different sunlight strength, but is also affected by temperature and spectrum and sunlight variation (shading) over a string of panels in series (note the optimum current varies distinctly with light strength W/m2).

To get maximum power, solar inverters have Maximum Power Point Tracking - MPPT - which keeps the DC panel string load near the optimum.

Hi frd,

will you please explain how MPPT is works in Central inverter which usually using in solar PV power plant?

in solar power plant....there is central inverter which converts the DC power to AC power at 3 phase Low voltage(360 to 420 V). please explain how this MPPT is works in this Central inverter?

MPPT is nothing but Maximum Power Point Tracking" more about solar inverter checkout here http://www.electricalmastar.com/solar-electricity/
