There are many ways to store the energy without chemical batteries.
We can use thermal batteries by heating water or other liquids and then release it at night. We can use kinetic batteries like compressing springs and then releasing them at night to turn a generator. Water batteries like hydro dams where you pump the water into a reservoir during the day and then release at night to again power a generator.
