I'm interested in exploring the payment plans available for solar panel installations. Specifically, I'd like to understand the different options you offer, including any financing, installment plans, or leasing options that may be available for customers like us. Could you also provide details on any potential financing terms, interest rates, and the overall process for payment? It would be helpful to have a clear understanding of how these plans work to better evaluate the total cost investment for our project.
