Panel Efficiency Evaluation in Mission Beach, California

Common Challenges

• Coastal salt and sand reduce panel output

  Mission Beach systems collect salt spray and sand that scatter light and reduce energy production, often without obvious visual cues.

• Shading hides underperforming modules

  Partial shading from palm trees or structures creates array sections that fall short of expected output and skew overall system data.

• No data to explain production drops

  Homeowners see lower yields but lack quantified soiling or shading estimates to decide between cleaning and further diagnostics.

How We Help

• Measured expected vs actual output

  On-site checks compare inverter and meter readings to expected output and report percent deviation for each array section.

• Soiling loss estimate in percent terms

  A focused assessment estimates how much dirt and salt reduce glass transmittance and models likely percent gains from cleaning.

• Targeted cleaning scope

  Findings guide whether localized panel washing or full-array cleaning is needed, avoiding unnecessary costs and roof access.

• Clear next-step recommendations

  Each report lists recommended actions, from deionized rinses to shading mitigation, with rationale tied to measured output gaps.
