When choosing a solar heating system installer, consider their experience, certifications, customer reviews, warranty offerings, and knowledge of local regulations.
Selecting the right solar heating system installer is crucial for maximizing efficiency, savings, and long-term performance. With solar energy becoming more accessible, knowing the key criteria for choosing a professional installer ensures you get the best return on investment.
1. Verify Credentials and Certifications
Always check if the installer holds industry-recognized certifications. The most respected credential is from the North American Board of Certified Energy Practitioners (NABCEP). This ensures they meet high standards for design, installation, and safety.
Licensing and Insurance
- State-required electrical and contractor licenses
- General liability and workers’ compensation insurance
2. Evaluate Experience and Track Record
An installer with years of experience is more likely to handle complex installations efficiently. Ask for:
Portfolio of Past Projects
- Residential or commercial solar heating systems
- Examples of installations similar to your needs
Customer References
Request at least three references and ask about:
- System performance
- Installation timeline
- Post-installation support
3. Assess Equipment Quality and Warranties
High-quality components ensure better efficiency and longevity. Compare:
| Component | Top Brands | Warranty Period |
|---|---|---|
| Solar Collectors | Heliodyne, SunEarth | 10-12 years |
| Pumps | Grundfos, Taco | 2-5 years |
| Controllers | Resol, SolarEdge | 5-10 years |
Workmanship Warranty
Look for installers offering at least a 5-year warranty on labor. Some top companies provide 10-year coverage.
4. Compare Pricing and Financing Options
Get multiple quotes to ensure competitive pricing. Be wary of bids significantly lower than others – this may indicate subpar equipment or shortcuts.
Financing Options
- Solar loans
- Lease agreements
- Power Purchase Agreements (PPAs)
