📊 Factors That Impact Cost
Roof condition and orientation
high ImpactSouth-facing roofs without shading are ideal. Poor roofs need replacement first
Local sun exposure (solar irradiance)
high ImpactSouthwest has 30-40% more solar potential than Northeast
Electric rates and net metering
high ImpactHigh rates and good net metering policies improve payback significantly
Available incentives
high ImpactFederal 30% tax credit plus state/local rebates can cut costs in half
Home energy usage
medium ImpactHigher usage justifies larger systems and faster payback
Roof age and material
medium ImpactNew roofs ideal. Tile/metal better than asphalt shingles
💡 Money-Saving Tips
Get multiple quotes from certified installers - prices can vary 20-30% for identical systems
Time installation to maximize tax credits - 30% federal credit available through 2032
Consider solar loans with $0 down - monthly savings often exceed loan payments
Size system to offset 80-100% of annual usage for optimal economics
Choose quality panels with 25+ year warranties - cheap panels cost more long-term
Install during off-peak seasons (fall/winter) when contractors offer better pricing
Group purchases with neighbors to negotiate volume discounts
Upgrade roof first if it's over 10 years old to avoid reinstallation costs
