What Sets Delaware Installers Apart
Delaware's small size and coastal climate mean installers must navigate strict state licensing, the Delaware Renewable Portfolio Standard, and potential salt‑air corrosion. Look for companies registered with the Delaware Division of Professional Regulation and experienced with the state's net‑metering rules.

Licensing and Certifications
Verify that the installer holds a valid Delaware contractor's license and is certified by the North American Board of Certified Energy Practitioners (NABCEP). These credentials ensure compliance with local building codes and high installation standards.
Understanding State Incentives
Delaware offers a 30% tax credit on solar systems up to 5 kW and additional utility rebates. An installer familiar with the Delaware Sustainable Energy Utility (DSEU) program can streamline paperwork and maximize your savings.
Service Models and Pricing
Installers typically offer three models:
- Full purchase – you own the system outright.
- Solar loan – financing spreads costs over 5‑20 years.
- Power purchase agreement (PPA) – the installer owns the panels and sells you electricity.
Compare total installed cost, expected payback period, and maintenance clauses across these options.
Maintenance and Warranty
Look for a warranty that covers both equipment (usually 10‑25 years) and workmanship (5‑10 years). Ongoing maintenance plans often include cleaning, inverter checks, and performance monitoring, which are crucial in Delaware's humid coastal environment.
Choosing the Right Installer
Use these criteria to evaluate candidates:
- Local experience with Delaware residential projects.
- Positive reviews on Google, Yelp, and the Better Business Bureau.
- Transparent quotes that break down hardware, labor, permits, and incentives.
- Availability of a performance guarantee or production estimate.
