Location and Client Url: http://www.nytimes.com/2012/06/03/us/new-plan-yields-hint-of-hope-for-aging-la-coliseum.html?_r=0

Location Los Angeles Memorial Coliseum ● Home of Rose Bowl Renovating: ● $70 million across 10 years Url: http://football.ballparks.com/NCAA/Pac12/USC/aerial.jpg

Client City of Los Angeles ● Owns the stadium/parking lots ● Some municipal buildings already have solar panels Url: http://culturela.org/musicla/

Technology Review ● Related Projects ○ FedEx Field ● Proposed Technology ○ Solaire Generation ● The Solar Carport Market

Related Projects FedEx Field ● 79,000 people ● Cost: $12,700,000 ● 2 MW peak load ● 100% of energy on off days ● 20% on game days Url: https://www.clarkconstruction.com/our- work/projects/fedexfield-solar-panel-installation

Proposed Technology Solaire Generation Existing Projects ● Rutgers ○ 8 MW ○ Yingli 206 W panel ● J&J ITS Headquarters ○ 2.1 MW ○ Sunpower 305 W Panel Url: http://solairegeneration.com/our-vision/stadium/

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 Url: http://www.washingtonpost.com/news/energy-environment/wp/2015/01/28/the-best-idea-in- a-long-time-covering-parking-lots-with-solar-panels/

Technological Constraints ● Assess solar resource ● Shading ● Fixed vs. Tracking ● Competitive fuels

Shading

Fixed vs. Tracking

Competitive Fuels

Socioeconomic Constraints ● Client Demands and Loading Estimates ● Electricity Rate Structure ● Federal and State Incentives ● Financial Model

Client Demands ● Irregular Loading ● Beaver Stadium as an estimate ○ larger size ○ higher energy demand Url: http://www.raystownlakehotel.com/raystown-lake-events/beaver-stadium-psu/

Loading Estimate

Electricity Rate Structure

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

Design Criteria ● Inverter ● Modules ○ Yingli Energy (China) YL260P-35B ○ Sunpower SPR-305E-WHT-D ● Tilt ● Shadowing Effects

Inverter Eaton Xpert 1670 357V ● 1.671 MW ● One inverter required http://www.eaton.com/ecm/groups/public/@pub/@electrical/documents/content/pa08303003e.pdf
