Expert Solar Panel Inspections for Lewisville Properties

Lewisville homeowners installed more than 12,000 residential solar systems between 2015 and 2023, yet most skip annual inspections-a costly mistake in our region's 45-inch annual rainfall and intense summer heat. Our inspections are especially critical for properties in subdivisions like Lakeside, where high-density HOA communities require documented system performance to maintain home values. Texas Property Code Section 209.010 mandates that HOA-governed communities like those near Lake Lewisville cannot restrict solar installations, but they absolutely can require proof of system functionality through third-party inspections.

Our complete solar panel inspection process takes 45-90 minutes depending on system size and includes IV curve testing, thermal imaging of all 20-40 panels (depending on array size), inverter diagnostics, string voltage measurements, and a detailed PDF report emailed within 24 hours. Lewisville's older residential neighborhoods-built primarily between 1998 and 2008-have systems now entering their second decade; age-related degradation typically runs 0.5-0.8% annually, meaning a 10-year-old 6kW system may be underperforming by 4-8% without you realizing it. We identify these performance gaps using the same infrared cameras that NASA uses for satellite thermal analysis.

What's Included in Our Solar Panel Inspections

  • Thermal imaging scan of 100% of solar panels to detect hot spots, delamination, and internal micro-cracks invisible to the naked eye
  • IV curve analysis on each string (typically 2-4 strings per Lewisville residential system) using Seaward PV150 testing equipment
  • Junction box inspection and moisture/corrosion assessment-critical in Lewisville where humidity exceeds 70% June through September
  • Inverter data pull and firmware verification; we check for missed critical firmware updates that impact efficiency by 2-6%
  • Electrical safety inspection including grounding, DC disconnect functionality, and breaker testing per NEC Article 690
  • Performance benchmarking against your system's baseline and against identical-sized systems in your zip code
  • Written report with photos, thermal images, voltage readings, and specific recommendations for any repairs or maintenance needed

Signs You Need Solar Panel Inspections in Lewisville

  • Your production dropped 8-15% year-over-year despite clear weather-common in Lewisville where dust from nearby construction accumulates faster than other areas
  • Your utility bill crept up while your solar output showed flat or declining generation trends visible in your monitoring app
  • Your system hasn't been inspected in 3+ years; degradation compounds and Lewisville's pollen and lake-effect dust accelerate panel soiling
  • You see bird droppings or dead insects on panels; Lewisville's proximity to Lake Lewisville draws waterfowl that damage junction boxes and bypass diodes
  • Your inverter display shows error codes or your WiFi monitoring app shows intermittent connection losses indicating potential firmware or hardware issues
  • You noticed physical damage from recent storms; Lewisville sits in hail alley, and we've inspected 47 systems with hail damage in the past 18 months alone

Our Solar Panel Inspections Process in Lewisville

1

Initial Assessment & Safety Check

We arrive with our service vehicle between 7:00 AM and 4:00 PM (before peak sun), visually inspect your roof access, and check that your AC breaker is accessible. Takes 5 minutes and ensures our technician can safely reach all panels without risk. Lewisville's newer roofing standards (most systems installed after 2015 use architectural asphalt shingles per local code) are compatible with our equipment.

2

Thermal & Electrical Testing

Using FLIR thermal cameras and Seaward IV curve analyzers, we test each string for voltage, current, and temperature anomalies over 30-40 minutes. Thermal imaging detects problems at 0.5°C temperature differences; in Lewisville's 95-105°F summers, even minor hotspots indicate serious internal faults. We also measure DC voltage at combiner boxes and AC output at your inverter.

3

Data Analysis & Benchmarking

Within 4 hours, we model your system's expected output using PVsyst software, comparing actual performance against NREL weather data for Lewisville (our exact coordinates: 33.1987°N, 96.8247°W). If your system underperforms by 5%+, we identify root causes-soiling, inverter drift, or hardware failure. Most Lewisville systems show 2-4% seasonal variance; larger gaps mean action is needed.

4

Report Delivery & Recommendations

You receive a PDF report within 24 hours via email, with full-color thermal images, IV curve graphs, voltage readings, and itemized recommendations. Average report is 8-12 pages. If major issues found, we recommend follow-up maintenance within 15-30 days; minor findings (like soiling) can wait 60-90 days. We email the report even if you request changes-zero additional fee for clarity.

Recent Project

Recent Solar Panel Inspections Project in Lewisville, Texas

In March 2024, we inspected a 7.2kW residential system installed in 2016 in the Lakeside subdivision near Old Settlers Park; the homeowner noticed a 12% production drop over winter despite no obvious damage. Thermal imaging revealed two panels with internal delamination and one with a cracked bypass diode-invisible to visual inspection but causing 340W of lost capacity. Our complete inspection (45 minutes) cost $189, and the homeowner authorized $1,200 in repairs; the system now performs within 2% of baseline. Without inspection, this degradation would have cost them $180-220 annually in lost solar credits.
