I'm reaching out to inquire about solar products. I'm particularly interested in options that are suitable for residential and commercial use, focusing on efficiency and durability. Could you please provide me with details on your available solar panels, including specifications, pricing, and any current promotions? Additionally, I'd like to understand more about your warranty policies and installation services. It would be helpful to know the typical lead times for orders and if you offer any financing options. Looking forward to your prompt response with all the relevant info. Thanks!
