Carport Market

Benefits

  • Minimizes heat island effect
  • Increased car efficiency
  • Less physical/regulatory barriers
  • Prices for carport PV declining

Challenges

  • Higher average per kWh cost

○ Less competitive

Socioeconomic Constraints

  • Client Demands and Loading Estimates
  • Electricity Rate Structure
  • Federal and State Incentives
  • Financial Model
slide-16
SLIDE 16

Client Demands

  • Irregular Loading
  • Beaver Stadium as an estimate

○ larger size ○ higher energy demand

Federal and State Incentives

  • Solar Investment Tax Credit 30%
  • California Solar Initiative Calculator

○ %0.025/kWh State production Tax ○ Over 5 years

  • Database of State Incentives for Renewables

○ $0.00039 / W capacity incentive

Financial Model

  • Financial Modeling Performed in SAM

○ Loan of $5,086,154.00 ■ 100% debt for 25 years ■ rate of 7.5% per year ○ Inflation rate = 2.5% ○ Real discount rate = 5.5% ○ Taxes ■ Federal/State income tax = 28%/7% ■ Sales Tax = 5% ○ Insurance rate = 0.5% of installed cost
