Yes, you can use solar panels without battery storage. Solar panels generate electricity from sunlight, which can be directly used to power your home's appliances and electrical devices. When your solar panels produce more electricity than you're using , the excess power is sent back to the DISCOM if you're connected to it, from this procedure you can earn money to sell excess electricity back to the grid and its depanding on your local regulations this is know as Net Metering System.
Battery storage, on the other hand, allows you to store excess solar energy for use during times when the sun isn't shining, such as at night or during cloudy days. While battery storage can provide energy independence and help you utilize more of the energy you generate, but it's not a requirement for using solar panels.
Without battery storage, you'll still benefit of reduced upto 80% electricity bills during the day when your solar panels are producing electricity. The grid acts as a "virtual" storage system, allowing you to draw electricity from it when your solar panels aren't generating enough power. This type of system known as "on grid solar system." The decision to include battery storage depends on factors like your energy consumption patterns, local utility rates, and your desire for energy resilience during grid outages.
