Financing homeQuestions people often ask
Why wasn't a battery added before?
Your panels and battery may have been priced separately. The right battery also depends on your current equipment, wiring, and home. We check those things before recommending an upgrade.
Does checking my rate hurt my credit?
The initial rate check has no credit score impact. A full loan application may involve a hard check.
What is covered?
The battery upgrade includes a 25-year all-inclusive warranty. We connect it with your existing solar system and check that the finished system is in good working order. Your agreement explains the warranty terms.
