Dear Nirmal, Most systems are infact hybrid. While, panels power the applications with lower load, the grid will power the high load applications such as ACs. Do you have a UPS/Inverter at home? It’s going to be exactly like that. Except that your battery in the inverter will get powered by sun instead of getting charged by grid. Does this answer your question or were you asking about grid tie/ hybrid systems? If that was the case then at present our grids dont support such infrastructure. You can read our articles to understand more about how a solar inverter works. See: https://sauryaenertech.com/solar-inverter-and-regular-inverter/ Do you think Solar panels can save your power bills?
