I'm reaching out to inquire about the warranty details for your solar panels, specifically regarding their lifespan and reliability. We recently had an unfortunate experience where one of the units we purchased stopped functioning within just six months of use. It has raised some concerns on our end, and we'd appreciate understanding how your product guarantees durability over time. Could you please provide more detailed information on the expected lifespan of the solar panels? Additionally, if there are any specific warranty terms or conditions that we should be aware of, that would be really helpful. This information will not only assist us in assessing the reliability of your products but will also guide us in our future purchasing decisions. Looking forward to your prompt response.
