I'm looking to purchase three solar plates for a project I'm working on. Could you provide me with details regarding the specifications, available options, and pricing? I'm particularly interested in understanding the efficiency ratings and any warranty or support services that come with the products. Additionally, please let me know about the lead times for delivery and any bulk order discounts you might offer. If you have any recommended models that fit my needs, I would love to hear your suggestions. Looking forward to your prompt response!
