A typical solar generator can last at least 25 years, but it may be capable of surviving for 30 years or longer for some styles and models of solar generators. Compared to traditional gas generators, solar generators have very few moving parts. With less complexity, there is little maintenance and little to break down over time. One of the most attractive features of a solar generator is the ease of generator maintenance and extremely long lifespan.
To prolong a solar generator’s life even longer, take good care of the control panel and the battery. Damage to the battery can impact its ability to charge fully and store a powerful charge for an extended time. Most solar-powered generators have a full warranty for up to five years.
Keep in mind that solar generator longevity is measured in the length of time a solar battery can sustain a charge of at least 80%. Over time, batteries become less effective with continued usage. Just because a solar backup generator is deemed past its prime, it may still be able to hold and store a charge just under 80% capacity. A generator retaining 70% or even 50% of its charge can be critical during power outages.
