The lifespan of a commercial solar installation depends on several factors such as the quality of the components, the level of maintenance, and the local weather conditions. Generally, solar panels have a lifespan of 25-30 years, although some newer models have longer lifespans. It’s important to note that regular maintenance can help extend the lifespan of all components. Some commercial solar panel systems installed in the early 90s are still working well today! Additionally, the warranties provided by manufacturers may cover certain repairs or replacements within a specified period.
