Panel Efficiency Evaluation Old Town San Diego

Common Challenges

• Soiling causes unmeasured energy loss

  Dust from foot traffic and pollen reduce glass clarity in Old Town, cutting production by a few percent or more if left unchecked.

• Shading hides underperforming modules

  Partial shading across array sections lowers local output and skews system data, making it hard to find faults without section checks.

• Unclear cause leads to unnecessary washes

  Without targeted evaluation owners often schedule full-array cleaning that adds cost and roof access risk without proven production gains.

How We Help

• Soiling loss percentage estimate

  On-site checks compare expected vs measured output to produce a percent estimate of loss attributable to dirt and shading.

• Targeted cleaning scope

  We identify which array sections need washing so you avoid full-array cleans and reduce labor, water, and roof access time.

• Shading and mismatch flagged

  Section-level observations note shading patterns and module mismatch so follow-up diagnostics or repositioning can be prioritised.

• Concise service summary and next steps

  You receive a short report with findings, estimated gains, and recommended next actions such as cleaning or further testing.
