Solar Panels in New Jersey: What Homeowners Should Know
Roof condition, shading, interconnection and contract terms decide whether a system performs as promised.
Rooftop solar is a twenty-five-year decision attached to a specific roof. The diligence that matters happens before signing.
Before you get quotes
- Know your annual kilowatt-hour usage
- Know the age and remaining life of your roof
- Photograph tree cover on the south and west sides
- Check homeowners association or historic district rules if applicable
Comparing proposals fairly
| Compare | Why it matters |
|---|---|
| Price per watt | Normalizes systems of different sizes |
| Estimated annual production | Drives every savings claim |
| Equipment warranty | Panels and inverters differ |
| Workmanship warranty | Covers roof penetrations |
After installation
Monitor production for the first full year against the modeled estimate. Persistent shortfalls should trigger a service call while workmanship coverage is active.
