I'm reaching out to inquire about the service package you offer for the panels. Specifically, I'd like to understand whether cleaning and maintenance are included in this package. It's important for us to know what level of care and support we can expect to maintain the performance and longevity of the panels. Additionally, if you provide any detailed breakdown of the services included, it would be helpful for our evaluation. Understanding the scope of maintenance and cleaning support will aid us in making an informed decision about our procurement choices. Please share any relevant details when you get a chance!
