Dixon sits in the heart of almond country and carries some of the heaviest pollen and Central Valley dust exposure in the region. Solar owners here typically see production drops of 12–18% by mid-summer if panels aren't cleaned regularly (industry-typical for this micro-climate). The seasonal plan is the right call in Dixon — the cleaning ROI math is favorable faster here than in lower-exposure areas like Roseville or Folsom.
Spring (March–May): Dixon is in the middle of almond country. Pollen exposure is the highest in our service area. The April clean here is non-negotiable for any solar owner.
Summer (June–Aug): Adjacent to multiple working ag fields. Dust accumulation is 15–20% faster than Davis or Sacramento. Mid-July clean strongly recommended; mid-August follow-up sometimes warranted.
Fire season (Sept–Oct): Moderate exposure — Dixon often gets smoke plumes from Solano County fires (LNU Lightning Complex, multiple Vacaville-area fires).
Winter (Nov–Feb): Less bird activity than denser cities; less December bird buildup. Mineral streaks from rain are still common.
