Efficiency Metrics Performance Evaluation in Phoenix, Arizona

Common Challenges

• Dust and monsoon residue cut energy output

  Dust-prone Phoenix roofs and monsoon residue reduce seasonal production by 10-25%, often masking underperforming panels until measured.

• Shading from new structures or trees

  New shade on downtown Phoenix arrays or neighborhood trees causes string mismatches and steady kWh loss that basic monitoring can miss.

• Inverter constraints cap system performance

  Inverter clipping, mismatched strings, or firmware limits can cap output; diagnostics reveal whether hardware or configuration is the cause.

How We Help

• Baseline energy measurements in kWh

  On-site production logging and string-level kWh measurements establish a baseline for comparison and seasonal performance tracking.

• Panel loss measured as percent of expected output

  IV-curve and output analysis quantify each panel's percent deviation from manufacturer spec to prioritise cleaning or repair.

• Locate shading and hot cells quickly

  Thermal imaging and IV-curve testing pinpoint shaded modules and hot cells so targeted repairs restore production efficiently.

• Actionable, itemized follow-up plan

  We deliver a ranked plan—cleaning, microinverter swap, or reconfiguration—with expected production gains and suggested timing.

• Timing aligned with Phoenix seasons

  Recommendations include post-monsoon cleaning and pre-summer checks to reduce dust and heat-related output losses.
