6. Introduction
Now a days with growing population & Energy we should
take a renewable option of energy source. Our aim is to
use solar energy for household loads using an inverter.
Solar energy is converted to electrical energy by
photovoltaic (PV) cells. This energy is stored in batteries
during day time for the utilization purpose whenever
required.

7. Introduction
A solar inverter, or PV inverter, Converters the direct
current (DC) output of a photovoltaic solar panel into a
utility frequency alternating current (AC) that can be FED
into a commercial electrical grid or used by a local, off-
line electrical network.

8. Objective
Efficiency, size, and cost are the primary advantages of
switching power converters when compared to linear
converters. The switching power converter efficiencies can
run between 7080%, whereas linear converters are usually
30% efficient. The DC-DC Switching Boost Converter is
designed to provide an efficient method of taking a given
DC voltage supply and boosting it to a desired value.

16. Solar panel refers to a panel designed to absorb the sun's rays as a source of
energy for generating electricity.
Expose the cell to light, and the energy from each photon (light particle)
hitting the silicon, will liberate an electron and a corresponding hole.
This flow of electrons is a current; the electrical field in the cell causes a
voltage and the product of these two is power .
Solar panel is an array of Several solar cells (Photovoltaic cells).

17. The energy generated by the solar panel, in the form of direct current (DC),
is transmitted to the inverter. The job of the inverter is to convert the DC
power to alternating current (AC) that is transmitted on the grid.
The transformer will then step up the voltage from 12 volts to 230volts,
which is the voltage used throughout the Indian electrical grid. This
conversion of voltage is what allows a 12 volt DC solar panel to be tied into a
230 volt AC grid.
About the inverter
18. 18
Pulse Width Modulation or PWM technology is used in Inverters to
give a steady output voltage of 230 or 110 V AC irrespective of the
load.
The Inverters based on the PWM technology are more superior to
the conventional inverters.
The use of MOSFETs in the output stage and the PWM technology
makes these inverters ideal for all types of loads.

1. Inverters are usually about 95% efficient. Inverters play a
significant role in providing alternate current supplies at the
time of crucial power requirement. The primary use of solar
inverters is to convert direct current to alternating current
through an electrical switching process.
