If you’re researching Itek solar panels, you’ve likely discovered conflicting information about this American solar manufacturer. This comprehensive guide provides the definitive answers about Itek Energy’s products, company status, and what it means for existing customers and potential buyers in 2025.
The Rise and Fall of Itek Energy Solar Panels
Itek Energy was once a promising American solar panel manufacturer that captured significant market attention, particularly in the Pacific Northwest. However, the company was acquired by Silfab Solar in August 2018, effectively ending Itek’s independent operations and leaving many customers with questions about warranty support and product availability.
For existing Itek panel owners, this acquisition means limited warranty support and no direct manufacturer backing from the original company. New solar buyers should understand that Itek panels are no longer available for purchase, making this guide primarily valuable for understanding the company’s legacy and finding suitable alternatives.
The implications of Itek’s acquisition extend beyond simple product availability – it highlights the challenges facing American solar manufacturing and the importance of choosing established manufacturers with strong financial backing.
Itek Energy Company Background & History
Founded by CEO John Flanagan in 2009, Itek Energy began operations with ambitious goals to establish a significant American solar manufacturing presence. The company’s flagship facility in Bellingham, Washington, employed over 150 people at its peak and represented a substantial investment in domestic solar production.
Key Company Milestones
- 2009: Company founded with Bellingham, Washington facility
- 2014: Expansion to Minneapolis, Minnesota with second production facility
- 2017-2018: Peak production years with strong regional presence
- 2018: Company acquired by Silfab Solar
The Bellingham facility was strategically located 90 minutes north of Seattle, providing access to skilled workers and proximity to key Pacific Northwest markets. The company’s Made-in-America certification qualified customers for significant state incentives, particularly Washington’s generous solar incentive program.
Itek’s business model focused on serving the domestic market with high-quality monocrystalline panels. The company emphasized rigorous quality control processes and positioned itself as a premium American alternative to imported panels.

Performance Analysis & Real-World Testing
Customer-reported performance data reveals both strengths and concerns about Itek solar panels. While many customers reported satisfaction with initial performance, some experienced higher-than-expected degradation rates.
Customer-Reported Performance Data
Based on 45+ customer reviews with an average rating of 4.66/5, most Itek panel owners reported positive experiences during the first few years of operation. However, some customers noted concerning degradation rates.
One customer reported degradation rates of approximately 2% annually, which significantly exceeds the industry standard of 0.5-0.8% per year. This finding suggests potential quality control issues or manufacturing defects in some production batches.
Weather Resistance and Durability
Pacific Northwest customers generally reported good performance in challenging weather conditions, including:
- Consistent power generation during cloudy conditions
- Adequate snow load resistance
- Good performance at low roof angles (as low as 9 degrees)
- Satisfactory appearance retention after several years
Efficiency Comparisons
Itek’s efficiency ratings were competitive for their time, with the IT-365SE achieving 18.3% efficiency. However, by 2025 standards, these efficiency levels are considered moderate, as high-efficiency solar panels now offer ratings exceeding 22% efficiency with superior long-term performance guarantees.
Quality Control & Manufacturing Standards
Itek Energy emphasized quality control throughout its manufacturing process, implementing several inspection procedures designed to ensure consistent product quality.
Bellingham Facility Quality Processes
The company’s quality control procedures included:
- Electroluminescent Imaging: Each module underwent EL testing to identify cell defects and micro-cracks
- 100% Visual Inspection: Every panel received comprehensive visual inspection at multiple production stages
- Materials Assessment: Stringent incoming material quality standards
- Performance Testing: Flash testing to verify electrical specifications
Despite these quality measures, some customers experienced performance issues, suggesting that quality control procedures may not have been sufficient or consistently applied across all production runs.
