Key Factors to Consider When Choosing a Solar Company

Warranty Coverage

Warranty protection is perhaps the most critical factor when selecting a solar installer. Reputable companies offer comprehensive warranties covering both equipment and workmanship. Most top providers offer 25-year equipment warranties with 10-year workmanship warranties, ensuring you’re protected against defects and installation errors for decades.

Certification and Credentials

Look for installers with NABCEP (North American Board of Certified Energy Practitioners) certification, which indicates they’ve met rigorous training and competency standards. This certification demonstrates a commitment to professional excellence and customer protection.

Financing Options

Different companies offer various financing approaches including system purchases, loans, leases, and power purchase agreements (PPAs). Understand which options align with your financial goals and long-term plans.

Customer Service Quality

Exceptional customer service extends beyond the initial sale to include responsive support, system monitoring, and maintenance assistance. Review customer testimonials and BBB ratings to gauge service quality.

Regional Availability

Verify that your chosen provider operates in your geographic area and understands local permitting, weather conditions, and energy markets.

Frequently Asked Questions

Q: How long does a residential solar installation typically take?

A: Most residential solar installations can be completed in one to three days, though the entire process from consultation to activation may take several weeks to account for permitting, inspections, and utility interconnection.

Q: What is the average lifespan of a solar panel system?

A: Quality solar panels typically last 25-30 years or longer, with most degrading only 0.5-0.8% annually. Most manufacturers provide 25-year warranties covering this timeframe.

Q: Can I install solar panels if my roof is older?
