On-grid or grid-tie solar systems are by far the most common and widely used by homes and businesses. These systems are connected to the public electricity grid and do not require battery storage. Any solar power that you generate from an on-grid system (which is not used directly in your home) is exported onto the electricity grid and you usually get paid a feed-in-tariff (FiT) for the energy you export.
On-Grid Systems are solar PV systems that only generate power when the utility power grid is available. They must connect to the grid to function. The On-Grid System can send excess power generated back to the grid when you are overproducing for later use.

ADVANTAGES OF ON-GRID SYSTEM
Utilization of vacant rooftop space
No battery required - lower maintenance cost
Short gestation period
Net meter - 24/7 solar energy
P.S. Anti-Islanding rule means that your solar system will not generate electricity when there is a power outage in the area. Our system is UL1471 certified and complies with this regulation. This is done to ensure that there are no untoward incidents when linesmen are working on a line assuming that it is unpowered.
