I am reaching out to request a detailed quote for solar panels. We are looking to understand the various options available, so please include information on wattage specifications, efficiency ratings, and any available warranty options. Additionally, it would be helpful if you could provide insights into any certifications your panels may have, as well as the pricing breakdown for different quantities. Moreover, if you have any current promotions or bulk purchase discounts, please share those details too. We're considering a substantial order, so knowing your lead times and shipping options would be great. Feel free to include any recommendations you may have based on our needs, as we are keen to explore the best solutions for our project. Looking forward to your prompt response!
