Solar energy can be used directly for heating applications and converted to electricity via photovoltaic cells. Inverters are required to convert the DC electricity from solar panels to the AC electricity used in homes and buildings. There are different types of solar inverters depending on the application.
Voltage of PV panel should be more than 45V for solar inverter to operate and inverter can generate rated output only if PV voltage is equal or more than 65V. In order to connect the grid to output of the inverter, turn on the AC output MCB. As soon inverter is supplied with DC voltage, it tries to synchronize.
Observe the voltage and current waveform on oscilloscope. This gives the clear idea about distortion in current supplied by the solar PV inverter. Manually finding the maximum power of PV panel should be done carefully and under the guidance of experienced one. Keep all the connections properly tightened. To evaluate the cut-in speed of wind.
Usually at noon time, panels produce 60-70% of power for which it is rated i.e. from 350-300W. In this way we can judge the performance of solar inverter. For more precise results, PV panels can be connected to a variable resistance and PV curve can be drawn by varying the resistance.
The circuit allows the electrons to flow to the electron-poor back of the cell from the electron-rich front of the cell. Photovoltaic panels are oriented to maximize the use of the sun’s light, and the system angles can be changed for winter and summer. When a panel is perpendicular to the sunlight, it intercepts the most energy.
