How to make the payment using a credit card?

Hello everyone,

I’m having rooftop panels installed in two weeks and I’m wondering if anyone has paid the down payment using a credit card. I read some posts where people mentioned calling the billing department and making payments using multiple credit cards.

Do I need to call the billing department once the installation is complete to make the down payment? For instance, if the total cost is $25,000, can I make a down payment of $20,000 using my credit card?

Alternatively, do I need to call the billing department once the system has been turned on and the monthly finance payments are scheduled? However, I read somewhere that at this stage, only ACH bank payments are allowed.

I appreciate your help!
