To make the world cleaner, various contributions have been made by many people. This contribution includes a grid which helps in the connection of photovoltaic system. It helps in the causing of spinning electricity meter backward and trims the utility bills for the betterment of society.

A scientist stated high story that he learns solar potential by visiting National Renewable Energy laboratory (NREL). According to him, most of the PV Systems are setup for the disconnecting the grids form the systems by detecting the cases of important fault done in solar energy. But if the single PV systems of the homes cut the line, it will create a great difficulty for the owner of solar power. But the network balance could be disturbed with hundreds and thousands of these types of cases. This small disturbance will be turned into outage blacking in the whole city.

These electric utilities are facing a great challenge with the installation of maximum solar PV systems by the customers in their business and homes. These installations are growing with a rate of 60% every year with the capacity of 32 gigawatts. The injected power of the distribution lines created by the solar systems is causing various problems related to voltage and frequency controlling. It further enforces the establishment of grid system.

The main cause of this problem is an electronic system which helps in the conversion of direct current into alternating current which is supplied by the PV panels and flows on the power grid. This system is known as inverter. Today, large numbers of inverters are being sold to different business houses and personal homes for getting every time electricity. There is an synchronization of distribution grid with the correct voltage and frequency. They are not able to detect and identify the happening or activities performance done on the solar grid.

But latest inverters helps in the protection of PV Systems when there are no electricity. With the prevention of voltage and frequency deterioration, these systems can actually help in making grid; which allows the occurrence of hundreds and thousands of various PV offline panels.

Also, there is a development of innovative method which controls the stability of the grid with the incoming power from wind, solar and other forms of electricity generation. It leads to the connection of grid via inverter. A new technology known as virtual oscillator, allows the controlling of smart inverters which can help in the sensing and adjustment of grid disturbances like change in voltage and frequency on regular basis. The electric utility industry is evolving day-by-day. This is happening due to increase in the usage of PV panels by the home owners on their roofs. The supplied powers by these systems are generating centralized plants.
