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 Average Cost for a 3kW system (At $8 per watt) $15,400 (After State & Fed tax credits) Estimated electricity generated per year 5,700 kWh (kilowatt-hours) (kilowatt-hours) Estimated yearly value of PV generated electricity $570 (@ $.10/kWh)

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
