10 Questions to Ask Before Going Solar

Solar panels can slash your energy bills — but it's a big decision. These questions help you get it right.

1. Is your roof suitable?

Consider its age, direction, angle, shading and space. A south-facing, unshaded roof is ideal.

2. How much could you save?

Get an estimate based on your energy use and local sunlight, and compare it to the system cost.

3. Should you buy, finance or lease?

Buying gives the best long-term return; loans spread the cost; leases and PPAs mean little upfront but lower savings.

4. What incentives and tax credits apply?

Federal, state and local incentives can cut the cost substantially. Factor them in.

5. What's the payback period?

Divide the net cost by your annual savings to see how many years until the system pays for itself.

6. What panels and inverter are used?

Ask about efficiency, brand and the inverter type — quality affects output and lifespan.

7. What warranties are included?

Look for strong panel (25-year), inverter and workmanship warranties.

8. Do you need battery storage?

Batteries store excess power for night or outages, but add cost. Decide if it's worth it for you.

9. How does net metering work locally?

Check how your utility credits the excess power you send back to the grid.

10. Is the installer reputable and certified?

Choose a certified, well-reviewed installer — installation quality is as important as the panels.
