  • System size: The most significant cost factor. A 4kW system costs around $9,900, while a 12kW system runs about $29,600. Your ideal size depends on your electricity usage, roof space, and budget.
  • Panel type: Monocrystalline panels (most efficient, 20-22%) cost more per watt than polycrystalline (15-17% efficiency). For Montgomery homeowners with limited roof space, monocrystalline panels often provide better value despite the higher upfront cost.
  • Roof condition and angle: A south-facing roof with a 30-degree pitch is ideal in Montgomery. If your roof needs repairs or has a complex layout with dormers, chimneys, or skylights, expect additional costs. Flat roofs require tilt mounts, adding $500-$1,500.
  • Shading: Trees, neighboring buildings, or other obstructions that shade your roof reduce solar production and may require tree trimming or a specialized panel layout.
  • Inverter type: String inverters ($1,000-$2,000) are cheapest, while microinverters ($1,500-$3,000) and power optimizers maximize production per panel, especially with partial shading.
  • Installer and labor: Montgomery has a cost index of 0.85 relative to the national average, which affects labor rates. Get at least 3 quotes from local installers to ensure competitive pricing.
  • Permits and interconnection: Montgomery, Alabama requires permits for solar installations. Permit costs typically range from $200 to $500. Your installer usually handles this, but verify what is included in their quote.
