When we say something will "pay for itself," we mean that it will ultimately save or make enough money to cover its original cost. For example, if you invest in solar panels for your home, they may be expensive upfront, but over time they will save you enough money on electricity bills that they eventually "pay for themselves." This expression is often used when making decisions about investments or purchases, as we consider whether the long-term benefits will outweigh the initial cost.
