• System size: The most significant cost factor. A 4kW system costs around $9,600, while a 12kW system runs about $28,900. 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 Roanoke homeowners with limited roof space, monocrystalline panels often provide better value despite the higher upfront cost.
