Key Factors to Consider When Choosing a Solar Company

Financing Options

How you pay for solar dramatically affects your long-term costs:

  • Cash purchase: Lowest total cost, maximum savings over time. You own the system outright and qualify for all tax credits.
  • Solar loans: Many installers offer $0-down loans with competitive rates (typically 4-8%). You own the system from day one but make monthly payments.
  • Leases: Lower monthly costs but you don’t own the system. Tax credits go to the leasing company, not you. Often includes annual price escalators.
  • Power Purchase Agreements (PPAs): Similar to leases but you pay per kilowatt-hour generated rather than fixed monthly amounts.

Warranty Understanding

Not all warranties are equal. Look for:

  • Panel degradation guarantee: What minimum output percentage is guaranteed at year 25? Higher is better.
  • Workmanship warranty: Covers installation errors. Some are only 1-5 years; look for 10+ years.
  • Inverter warranty: Typically 10-15 years. Microinverters often have 25-year warranties.
  • Transferability: If you sell your home, does the warranty transfer to the new owner?

State-Specific Considerations

Solar company availability and economics vary significantly by state:

  • Net metering policies: Some states credit excess solar generation at full retail electricity rates; others provide less favorable compensation.
  • Utility interconnection rules: Process complexity varies, affecting installation timelines.
  • State incentives: Beyond the federal 30% tax credit, some states offer additional rebates or tax credits.
  • Installer experience: A company experienced in your utility’s specific interconnection process can prevent months of delays.

Red Flags to Avoid

Watch for these warning signs when evaluating solar companies:

  1. Pressure tactics: High-pressure sales calls claiming “limited time offers” almost always indicate bad faith. Real solar savings don’t evaporate overnight.

  2. No physical address: Legitimate installers have local offices. Be wary of companies that only provide P.O. boxes or no address at all.

  3. Unwillingness to provide references: Reputable companies connect you with past customers. Ask specifically about post-installation experience.

  4. Vague pricing: You should receive detailed proposals itemizing equipment, installation, permitting, and all associated costs.

  5. Missing licensing: Verify state contractor licensing through your state’s licensing board. Liability insurance is non-negotiable.

  6. Door-to-door sales: While some legitimate companies use this approach, it’s commonly associated with less reputable operations. Request an in-office consultation instead.


Frequently Asked Questions

Q: How long does it take to install residential solar?

Most residential solar installations complete within 1-3 days of physical work. However, the entire process—from signing your contract to flipping the switch—typically takes 4-8 weeks. This includes site assessment, engineering design, permitting (which varies significantly by municipality), equipment ordering, and utility interconnection approval.

Q: What is the federal solar tax credit?

The federal Investment Tax Credit (ITC) allows you to deduct 30% of your solar system costs from federal taxes. This applies to both purchased systems and solar loans. The credit is available through 2032, then decreases to 26% in 2033 and 22% in 2034. To qualify, you must own the system (leasing doesn’t qualify for the full credit) and your system must be installed at your primary or secondary residence in the United States.

Q: Is solar worth it in states with low electricity rates?

Solar makes economic sense even in lower-cost electricity states, but the payback period is longer. In states with electricity costs above $0.15/kWh (California, New York, Hawaii), solar typically pays back in 6-8 years. In states with rates around $0.10/kWh, expect 10-14 years. Consider solar worthwhile if you plan to stay in your home beyond the payback period and prioritize environmental benefits or energy independence.

Q: Can I install solar myself to save money?

DIY solar is possible but generally not recommended for most homeowners. While you can purchase equipment and handle installation yourself, electrical work carries safety risks, improper installation can void equipment warranties, and you’ll need to navigate complex permitting and utility interconnection processes. Professional installation typically costs $1-2 per watt—worth paying given the complexity and warranty protection.

Q: What happens to my solar system during a power outage?

Standard grid-tied solar systems automatically shut down during outages for safety—this protects utility workers from unexpected power flow. If you want backup power during outages, you need a battery storage system (like Tesla Powerwall or Enphase Encharge) or a solar-plus-storage system with islanding capability. Battery systems add $10,000-$20,000 but provide valuable resilience during grid failures.

Q: How do I verify a solar company’s reputation?

Check multiple sources before committing: The Better Business Bureau provides complaint history and resolution rates. State licensing boards verify contractor licenses and any disciplinary actions. Review sites like Yelp, Google Reviews, and the SolarReviews platform offer customer feedback. Specifically ask for 3-5 recent customer references and actually call them—ask about post-installation support and any problems encountered.


Conclusion

Choosing the right solar company ultimately depends on your specific circumstances—budget, location, roof characteristics, and financing preferences. Sunrun remains our top overall recommendation for most homeowners thanks to nationwide availability, flexible financing, and consistently strong customer satisfaction. SunPower earns the premium pick for homeowners prioritizing efficiency and long-term reliability. Tesla offers the best value for tech-savvy buyers comfortable with their minimalist service approach.

Before making a final decision:

  • Get at least 3 quotes from different installers using identical system specifications
  • Verify all warranties in writing before signing
  • Check licensing through your state contractor board
  • Understand your net metering policy from your utility company

The best solar company is one that educates rather than pressures, provides transparent pricing, and stands behind their work with solid warranties. Take your time, ask questions, and remember that the cheapest option rarely delivers the best long-term value in solar.
