The arrangement of solar modules absorbs the sunlight on them and convert them into electricity. The current generated here is Direct Current (DC). The solar inverter then converts the DC to Alternating Current (AC). On-grid systems send excess power generated to the utility grid when you are overproducing. These are the most cost-effective and simplest systems to install.
Solar energy provides a good return on investment through the use of non-utilised rooftop space and requires minimal maintenance. All of this has a positive impact on your savings and an even greater impact on the environment.
On-grid means your solar system is tied to your local utility’s GRID (DISCOM). This is what most residential homes will use because you are covered if your solar system under or over-produces in regard to your varying energy needs. All this means for you is that your utility system acts as your battery space. If you are producing more energy with your solar panels or system than you are using, the excess energy is sent to your grid’s power company, allowing you to build credit that you can cash out with at the end of every year, in a process called net metering. Being grid-tied is beneficial because you don’t have to buy an expensive battery back-up system to store any excess energy.
