The Homeowner Solar Checklist

Is Your Home Ready for Solar?

Going solar is one of the best financial decisions a homeowner can make — but a little preparation goes a long way. Use this checklist before you talk to any installer.

1. Roof Condition

• How old is your roof? Panels last 25–30 years; if your roof needs replacing in the next 5 years, do it first.
• Is the roof structurally sound? Installers will inspect, but obvious sagging or damage is a red flag.
• What material? Asphalt shingle and metal roofs are easiest. Tile and slate add cost.

2. Shading & Orientation

• South-facing roofs produce the most energy in the Northern Hemisphere.
• Nearby trees, chimneys, or neighboring buildings that cast shade will reduce output.
• Ask your installer for a shading analysis (most use tools like Aurora or Solargraf).

3. Your Electric Bill

• Pull 12 months of bills to find your annual kWh usage.
• A system sized to offset 80–100% of usage is typical.
• Higher bills = faster payback.

4. Questions to Ask Every Installer

• Are you NABCEP-certified?
• What equipment brands do you use, and what are the warranties?
• Do you handle permitting and utility interconnection?
• What is the estimated payback period for my specific home?

5. Incentives to Know

• Federal ITC: 30% tax credit on the full system cost through 2032.
• State rebates: Vary by state — ask your installer or check DSIRE.org.
• Net metering: Confirm your utility offers it and at what rate.
