  20. System sizing considerations • Electrical load requirement • Budget • Roof space / Land

  21. Advantages of PV • Reliable & Durable • 25 years for PV panels • 10 years for inverters • Low maintenance cost • Energy independence • Utah is ideal for PV

  22. Hedge against rising electricity rates • Utilities across the U.S are raising power prices • The price of coal has doubled since last year • Natural gas prices are up nearly 50% • More rate increases expected when federal legislation, anticipated by 2010, passes and forces coal-fired generators to pay fees to emit global-warming gases

  23. The Challenges of PV • Initial cost • Energy storage • Efficiency improvements • Lack of general knowledge • Power is still cheap in Utah

  24. System Cost & Performance

  25. Tax Credits • State Tax Credit • 25% (not to exceed $2,000) • Federal Tax Credit • 30% of the total system cost • Including installation • All solar equipment is exempt from sales tax

  26. Questions & Answers
