What is PV? The Photovoltaic Effect
Flat-Plate PV Systems • The most common array design uses flat-plate PV modules
PV System Types • Grid tie • Off grid • Stand-alone • Hybrid
Hybrid system PV & Wind
Mounting Options • Roof Mount • Ground Mount • Pole Mount • Building Integrated
PV Product Options • Monocrystalline & Polycrystalline • Shingles • Tiles • Thin Film
System sizing considerations • Electrical load requirement • Budget • Roof space / Land
Advantages of PV • Reliable & Durable • 25 years for PV panels • 10 years for inverters • Low maintenance cost • Energy independence • Utah is ideal for PV
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
The Challenges of PV • Initial cost • Energy storage • Efficiency improvements • Lack of general knowledge • Power is still cheap in Utah
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
