what batteries will last the longest for a solar panel system?

I want to install a solar panel system, but to connect to the grid they tell me i need permits and it has to be someone certified, and also it will cost 20k, so i will install some panels and connect it to batteries.
The question is, batteries dont last that long, will i have to buy new ones every 2 years?
