Evaluating Solar Installers: What to Look For

Choosing a solar provider isn’t just about price—it’s about trust, expertise, and long-term service. Here’s what separates the best from the rest:

• Licensing and Certification: Verify that the installer is licensed as a general contractor and electrician in your state. Look for certifications like NABCEP (North American Board of Certified Energy Practitioners).
• Experience and Reputation: How many installations have they completed? What do customer reviews and testimonials say about their service? Ask if they have experience with the type of system you want (battery backup, ground mounts, etc.).
• Custom System Design: Quality providers perform site-specific shading analyses and custom system designs—not one-size-fits-all quotes.
• Strong Warranties: Look for a minimum 10-year workmanship warranty and 25-year panel performance warranties.
• In-House Teams vs. Subcontractors: Ask if the work is performed by their own crews or third-party contractors. In-house teams generally ensure better quality control.
• Clear Communication: A good solar provider will answer your questions clearly, provide written timelines, and offer a single point of contact throughout your project.
