Solar panels produce direct electricity with the help of electrons that are moving
from negative to positive direction. Most of the appliances that we use at home
work on alternative current. This AC is created by the constant back and forth of
the electrons from negative to positive. In AC electricity the voltage can be
adjusted according to the use of the appliance. As solar panels only produce
Direct current the solar inverter is used to convert the DC to AC.
A solar energy generator produces square waves or a sine wave which can be used
for running lights, televisions, lights, motors etc. However these solar energy
generator also produce harmonic distortion. Expensive solar energy generator
make use of lots of steps to produce a sine wave and thus are found in residential
solar energy generator. Basically inverters should be a large one so that it supplies
enough power to all the necessary appliances.
