Common issues in Salem
Inverter efficiency loss
Degradation or malfunction in the inverter reducing DC-to-AC conversion efficiency. Often indicated by error codes or unexpected shutdowns.
Typical loss: 5–25%
Natural panel degradation
All solar panels lose efficiency over time at roughly 0.5–0.8% per year. Accelerated in extreme heat or poorly manufactured panels.
Typical loss: 3–15%

Solar inspection in Salem: frequently asked questions
How much does a solar panel inspection cost in Salem?+
A standard visual and electrical solar inspection in Salem typically runs $199–$349. A full thermal imaging audit using drone or handheld FLIR cameras costs $299–$549 for a residential 5–10 kW system, depending on roof access and panel count.
How many solar inspection companies serve Salem, OR?+
PanelAudit currently tracks 4 thermal and drone inspection providers covering Oregon, including national networks and OR-licensed local operators. Coverage varies by ZIP, so request quotes from 2–3 to compare turnaround and certifications.
What's the most common solar defect found in Salem?+
Inverter efficiency loss and partial shading are the leading findings in Salem, typically responsible for 5–25% of underperformance. Soiling is also relevant — low soiling, annual cleaning is typically sufficient.
How often should Salem solar owners get an inspection?+
Industry guidance is every 3–5 years for systems in Oregon, or annually if output has dropped more than 8% year-on-year. With 3.6 peak sun hours in OR, a 5-year cycle is usually adequate unless monitoring shows anomalies.
Can a drone inspection detect hotspots on my Salem roof?+
Yes. Most Salem thermal inspection providers use FLIR-equipped drones that fly the array at 15–25m altitude and identify cells running 10°C+ hotter than neighbours. This is the most reliable way to detect micro-cracks, bypass diode failure, and cell-level hotspots without panel removal.
Is a solar inspection worth it before claiming on warranty?+
Yes — most panel and inverter warranties in Oregon require third-party diagnostic evidence (thermal images, IV curves, or performance reports) before honouring claims. A $300–$500 inspection often unlocks $2,000–$8,000 in covered repairs or panel replacements.
