An On-grid solar system aka a grid-tied solar system is connected to the grid. Most Indian households with a reliable grid connection count on the on-grid solar system for their electricity needs. And we, at NTech, specialize in installing on-grid rooftop solar systems for both independent homes and housing societies. The generation of electricity in an on-grid solar system starts with solar panels and then goes through several steps to keep your house powered up during the day as well as at night. It uses a net meter (bidirectional meter) to transfer bulk units of electricity generated by the solar system during the day. The same meter also imports units from the grid.
