Homeowners today have an exciting opportunity to take control of their energy future by considering solar and/or battery installation for their homes. As interest grows, it’s important to ask whether your home or property is truly a good fit for solar and to understand the right questions to ask solar companies before moving forward. Vetting a business involves reviewing its licensing, customer reviews, asking questions and evaluating its track record to ensure it is reputable and a good fit for your needs. Carefully vetting potential installers helps ensure you choose a solar partner whose experience, transparency, and approach align with your long-term goals.

Question 1: How Long Does it take to Install Solar Panels?

Timelines can vary based on permitting, equipment availability and utility approvals. Asking this to solar companies upfront helps set realistic expectations and gives you a sense of how organized the company is.

Question 2: Do You Need a Permit for Solar Panels?

Yes, permits are required for installing a solar and/or battery system, as approval must be obtained from both the local municipality and the utility company before the project can proceed. The permitting timeline can vary by jurisdiction, as well as the project scope and the process itself is often complex and time-consuming. A reputable solar company will manage all required documentation and approvals to ensure a smooth, compliant installation while helping to avoid potential fines or delays.

Question 3: Is my House a Good Candidate for Solar Panels?

A trustworthy solar company will be upfront about when solar isn’t a good fit—whether due to roof issues, financial considerations or expected ROI. This question helps reveal whether the company has your best interests in mind or is just trying to make a sale.
