I'm reaching out to inquire about your solar panels. I'm interested in understanding the different types you offer, including details on their efficiency ratings, dimensions, and any certifications they may have. Additionally, could you provide information on the materials used in the manufacturing process? I aim to ensure that the products align with sustainable practices and meet high-quality standards. Furthermore, please share pricing information, including bulk order discounts and lead times for delivery. If you have any technical data sheets or product catalogs, that would be incredibly helpful. I'm looking to assess potential partnership opportunities and would appreciate your prompt response to help me move forward. Cheers!
