Mobile Solar offers a 5-Year Limited Warranty on all of its products. This warranty ensures our products shall, under normal use and operation, conform in all material respects to our written specifications and shall be free of defects in materials and workmanship. In some cases this 5-Year Limited Warranty is exceeded by individual component warranties. For example, the solar panels in our products carry either a 20 or 25-year power output warranty. We stand behind our products and the components that go into it.
