So, here’s a general guide going through the price differences between acquiring a solar-plus-storage or adding a battery after the installation.

Installing a solar-plus-storage system ensures from the start that all your equipment is entirely compatible.

Many people also purchase batteries for their existing solar system to earn savings. Having a stable source of energy reduces electricity costs and avoids demand charges. You can even apply to incentive and rebate programs to save on upfront installation costs.
