Most solar energy storage systems have a lifespan between 5 and 15 years. However, the actual lifespan depends on the technology, usage, and maintenance. Lithium-ion batteries generally have a longer lifespan (around 10-15 years), while lead-acid batteries may need replacement after 5-10 years (Dunlop, 2015).
