Key Qualities to Evaluate
- Experience and Credentials: Look for companies with several years in the industry and certifications such as NABCEP or local utility approvals.
- Warranty Coverage: A robust equipment warranty (typically 25 years for panels, 10–20 for inverters) and a workmanship guarantee (5–10 years) protect your investment.
- Financing Options: Loan, lease, or power‑purchase‑agreement structures can change the upfront cost and long‑term savings.
- Performance Guarantees: Some firms offer to pay you if the system underperforms relative to a projected output.
- Customer Support: Post‑installation monitoring, maintenance plans, and responsive service teams reduce downtime.
Comparing Pricing Models
Solar projects can be billed in a few different ways. Understanding the distinctions helps avoid surprises.
| Model | What You Pay | Typical Duration |
|---|---|---|
| All‑Up Front Purchase | Full cost of panels, equipment, installation, and permits | Pay once, own the system |
| Lease | Monthly fee for use of panels | Typically 20–25 years |
| Power Purchase Agreement (PPA) | Monthly fee based on generated kWh | Typically 20–25 years |
| Financed Loan | Monthly principal and interest payments | Repayment period varies, usually 5–10 years |
Local Incentives and Net Metering
State and municipal programs can reduce the net cost of solar. Common incentives include tax credits, rebates, and feed‑in tariffs. Net metering rules vary; a company familiar with local regulations can secure the best rates for excess power you export to the grid.
Installation Process Overview
The typical timeline from assessment to activation spans 4–8 weeks, depending on permitting and weather. A reliable company will:
- Conduct a site survey to assess roof orientation, shading, and structural integrity.
- Submit permits and coordinate with local authorities.
- Schedule installation, ensuring minimal disruption to your daily life.
- Perform a performance test and provide a detailed system overview to the homeowner.
Questions to Ask Before Signing
- What is the expected annual energy production and how does it compare to the system's rating?
- Can you provide references or case studies from similar roof types?
- What is the process for warranty claims, and who handles them?
- How will you handle maintenance and monitoring over the life of the system?
Final Decision Checklist
- Verify licenses and insurance coverage.
- Compare at least three proposals, noting equipment brands and total cost.
- Confirm the duration of warranties and any performance guarantees.
- Ask for a written breakdown of all fees, including permitting and interconnection costs.
- Ensure the company offers a post‑installation support plan.
