Why Your Solar Installer Choice Matters Most

Choosing a solar installer is a 25-year relationship. The wrong choice can turn a wise investment into a costly nightmare. A poorly vetted installer can lead to:

  • Financial Loss: Inaccurate savings projections, missed incentives, or failure to properly register your system for SREC payments can cost you thousands.
  • Installation Failures: Poor workmanship can lead to dangerous electrical issues, roof leaks, and system underperformance.
  • Voided Warranties: Improper installation can void the manufacturer warranties on your expensive panels and inverters.
  • “Ghost” Companies: Many smaller installers go out of business, leaving homeowners with an “orphaned” system and no one to call for service or warranty support.

Conversely, a top-tier solar company ensures a seamless process, a high-quality, resilient installation, maximized savings, and peace of mind for the entire lifespan of your system.

State-Specific Considerations for Delaware Installers

Delaware’s energy market demands specific expertise. When choosing an installer, ensure they have:

  • Rebate and SREC Expertise: A top DE installer must have deep experience with the Delmarva Power Green Energy Program rebate and the SREC market to ensure you receive all your money.
  • Local Utility Knowledge: They need a thorough understanding of the net metering and interconnection processes for Delmarva Power.

National vs. Local Solar Companies

Homeowners in Delaware have a wide choice of both large national brands and smaller local installers. Each has potential advantages:

  • National Companies: Often have more financing options and significant buying power that can sometimes lower equipment costs.
  • Local Companies: May offer more personalized customer service and a deeper understanding of your specific city’s permitting process.

Ultimately, neither is inherently better. The most important factors are a company’s commitment to quality, customer service, and local expertise.
