I'm looking to upgrade my current solar panel setup, as I'm seeking better efficiency and performance. I'm interested in exploring a few options that your factory offers, particularly those that align with my energy needs and budget. Could you please provide details about your latest solar panel models? I'd like to know about their specifications, pricing, and any available warranty options. Additionally, if there are any ongoing promotions or new technologies you're implementing, please share that info as well. Thanks!
