Tonight’s presentation is an introduction to Solar Electricity, or “Photovoltaics” 08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Solar Electricity is Photovoltaic (PV) Energy and is not Solar Thermal Energy ,[object Object],08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org Photovoltaic Technology is about making electricity directly from the sun.

Some basics: Solar electrical energy is mostly from the Visible range of the solar spectrum 08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org The Sun’s energy: about 51% is in Infrared about 46% is in Visible light about 3% is in UV radiation

More Basics: A quick definition for the glossary: Primary Energy ,[object Object],[object Object],08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org

Primary Fossil mix in the US Electric Grid (from the US EIA) 08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org * 96% of Indiana’s electricity comes from burning coal *

Primary Fossil energy costs are rising rapidly 08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org US EIA sources 2003 2004 2005 2006 Natural Gas Residential Price/MMBTU $9.63 $10.75 $12.81 $13.75 Natural Gas Electric Utility Prices/ MMBTU $5.57 $6.11 $8.45 $7.09 Bituminous Coal $/Ton $25.82 $27.30 $30.98 $31.70 Uranium Hexafluoride/lb $10.81 $12.61 $10.40 $13.90

08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org Chart compliments of Indiana Utility Regulatory Commission. Energy Prices are on the rise

08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org So are residential electricity rates ,[object Object],[object Object],[object Object],[object Object],Residential rates up nationally 14% in last 5 years – Outlook? All rising, and no expectation of dropping in foreseeable future.

08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org What’s Driving Energy Prices/Costs? Supply/Demand Political Factors Environmental War, Terrorism, Sanctions, Price Fixing = most attention Weather Patterns, “Natural” Disasters, Pollution = some coverage Population, Economic Growth, Resource Depletion = little to no attention or coverage

There is a global Paradigm shift underway in energy generation 08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org Mining energy – petroleum, coal, natural gas, uranium Harvesting energy – solar, wind, water, earth, biomass Living off capital Living off interest

The Power of the Sun on Illinois ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org Sources: U.S. Energy Information Agency National Renewable Energy Laboratory Oak Ridge National Laboratory 673 quads per year of solar energy per year 2,205 quads of coal in the ground Almost as much solar energy falls on Illinois in 3-1/2 years as all demonstrated recoverable coal under it!

Illinois as a whole buys more energy from out of state than it exports (this is true of Indiana also) 08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],U.S. Energy Information Agency ftp.eia.doe.gov/pub/state.prices/html/tcil.htm

Or a Better question: What can harvesting the Sun do for you? 08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org What Can tapping the Sun do for Indiana?

But first: What does Photovoltaic Power Look Like? 08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org

PV Works Well in Indiana 08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org A solar electric system will work about as well in Indiana as one in Miami, Florida, around 88% . A PV system in Indiana can out-produce a Miami system in the summer . PVWATTS simulation – Natl Renewable Energy Lab, 1 kW AC, 30 degrees fixed angle due south

Economic Values of Solar Electricity 08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org Energy savings (return on investment and “payback”) Incentives Indiana $0 from state for residential systems, some grants for commercial, non profit, K-12. 30% Federal Tax Credit. Property tax exemption. NIPSCO FIT. Typical residential payback now under 10 years! Commercial systems now under 5!! ( Illinois 30% State rebate plus Federal Tax Credit) Capital asset (additional home value at re-sale is often close to initial investment) Visit http://www.dsireusa.org/ to see incentives from other states then write your member of congress and ask why we don’t have any incentives in Indiana!

Other Values of Going Solar 08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org Pride in Ownership (satisfaction in taking part in solutions!) Greater Self Reliance/Resilience (Lower energy bills/locked in rates. Less dependence on foreign energy sources increases national security) Environmental Benefits (reducing carbon & mercury and other toxic emissions, not generating as much radioactive waste)

Cost of Solar Electricity (caveat!: all values estimated ) 08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org Grid-Tied System Now most common system in the United States PV Hybrid Partial battery backup Off-Grid Full battery bank, perhaps a generator for backup For a 2.5 kW ( Half a typical home’s energy use) 2.5 kW (1/2 typical home) 4 kW to 7 kW (Typ. Home, but assumes making EE improvements) $14,000 to $20,000 (30% rebate excluded) (tax credit excluded) $25k + (rebate? batteries not included) $35k +

Cost of Solar Electricity (caveat!: all values estimated) 08/16/11 Indiana Renewable Energy Association http://www.indianarenew.org Inverter warranties increasing/added value with extended warranties Grid-Tied System PV Hybrid Fully Off-Grid 2.5 kW 2.5 kW 4 kW to 7 kW Savings in utility cost at CURRENT utility rates: $350-400/yr $350-400/yr $800-$1,400/yr Annualized Maintenance $100/yr amortized cost of inverter replacement $150 -$300/yr inverter replacement & battery maintenance $350 -$450/yr inverter replacement & battery maintenance & replacement
