I'm interested in understanding more about the expected durability of the panels and inverter offered. Could you provide details on their estimated lifespan in various conditions? This info is crucial for assessing long-term performance and suitability for our needs. Additionally, I'd like to know about any warranties that come with these products. Are there different levels of coverage based on the specific components? Clarifying these points will help us evaluate the overall value and reliability of your offerings in our project planning. Thanks!
