What Affects Solar Panel Performance in Washington State?

 

Several factors impact solar panel output and durability, including:

 

Solar panel quality

Our tier-1 Talesun microcrystalline solar panels feature bypass diode technology to improve current flow and minimize losses around snow-covered panel sections. They outperform polycrystalline technology in both extreme heat and subzero temperatures.

Solar panel installation in Central Washington

Our experienced solar panel installers ensure weatherproof electrical wiring and securely mount panels at the correct angle to maximize sun exposure, while allowing snow and debris to slide off to prevent moisture damage and overheating.

Weather

High temperatures reduce voltage output and cause thermal degradation, while cooler temperatures decrease resistance and improve productivity, making the Yakima Valley region an excellent location for solar energy production.

Environment

Snow, leaves, dirt, dust, and debris accumulations, such as from storms, construction, or farming, can impact performance.

Solar panel age

Solar panel performance gradually decreases with daily wear, but typically retains 80-90% operational efficiency, even after 25+ years of use.

Solar Panel Maintenance Tips for Lasting Use

 

Solar energy system maintenance in Central Washington is minimal. To achieve optimal performance, reduce wear-and-tear, and maximize lifespan, we recommend:

 

  • Routine cleaning to eliminate buildup that can limit sunlight absorption and energy production

  • Trimming back branches and trees that cast shadows or drop leaves and debris on panels

  • Regular professional inspections every 1-2 years to verify energy production and inverter health, and identify potential wiring and mounting issues

  • Inverter replacement every 10-15 years to maintain peak energy output
