2 Why renewable energy? Renewable energy systems are an investment in our quality of life, our national security, and our environment Solar systems provide energy independence and insulation from utility cost increases Payback is improving as modules become more efficient and lower cost, and as traditional energy sources continue to become more expensive Federal & State incentives greatly reduce payback time Scarcity of fuels and environmental impact dictate t that t we change our energy strategy! t Copyright 2010 Dovetail Solar and Wind 2

How do I convince my management team (or spouse) that this is a good idea?

3 Typical Questions Is solar really viable in Ohio? What s this going to cost me? What will it do for me? What will I save? How do I convince my management team (or spouse) that this is a good idea? What other benefits or concerns should I be aware of? What are the important t evaluation criteria? Copyright 2010 Dovetail Solar and Wind 3

53 Solar Renewable Energy Credits Sell Environmental Attribute of solar energy generation to utility that t is required to produce quantity of clean power or equivalent offset This is in addition to savings from the electricity produced d by the solar system Dovetail offering contract for $250 per SREC (25 per kwh) for next 5 years (or $303 for 3 years) Can represent significant value for larger commercial systems in Ohio Ex KW Solar System produces 48,134 kwh/yr = $12,033 per year at 25 /kwh Copyright 2010 Dovetail Solar and Wind 53

54 Solar Renewable Energy Credits Alternatively we can provide up front cash for your SRECs upon system installation ti Dovetail offering contract for $1,150 per Kilowatt (1,000 watts) In exchange for SRECs for 10 years Provides substantial immediate cost reduction or down payment on solar system Ex. 50 KW Solar System = $57,500 cash payment Copyright 2010 Dovetail Solar and Wind 54

55 System Payback Depends on client specific parameters: System size, orientation, tilt angle, efficiency Solar irradiance or average wind speed at turbine Current electric usage & Utility rate(s) Tax rates Financed amount & loan interest rate Any planned efficiency improvements or increased usage Copyright 2010 Dovetail Solar and Wind 55

Impact of Electric Rates A key element in calculating payback for a system is the impact of future electric rate increases Wide range of rate structures across country 7.

56 Impact of Electric Rates A key element in calculating payback for a system is the impact of future electric rate increases Wide range of rate structures across country 7.5 up to over 25 per kwh Usually assume conservative 4% annual rate increase for financial projections For Ohio, many assume >8% annual increase in next 3 yrs as we transition to new regulations Compounding effect has major impact on your future electric rates Copyright 2010 Dovetail Solar and Wind 56

69 Tangible Benefits Lock In The Cost of Electricity Reduce Impact of Electric Rate Increases on Business Cash Flow (or your home budget) Move a portion of operational expenses to depreciable capital costs Provide more predictable operational costs Copyright 2010 Dovetail Solar and Wind 69

70 Other Tangible Benefits Increased Property Value A Solar PV System Increases the Resale Value of Your Property Government funded study found that home Resale Values increased by $20 for every $1 of reduction in annual utility cost Example A 3.7 KW Solar System produces 4,168 kwh per year = $542 per year Increase in Property Value = 20 x $542 = $10,840 Increases as Utility Electric Rate increases Copyright 2010 Dovetail Solar and Wind 70

72 Environmental Impact Example A 32.3 KW Solar Array over 25 years avoids: 1,328,000 lbs of CO 2, the leading greenhouse gas 4,263 lbs of NO x, which creates smog 3,859 lbs of S0 2, which causes acid rain 263 lbs of particulates which cause asthma Or: 2,162,000 miles driven in an average car Or: planting 11.4 acres of trees Copyright 2010 Dovetail Solar and Wind 72

73 Financing Alternative 3 rd Party Ownership 10 to 20 year Power Purchase Agreement Typically set at 85% to 100% of utility electric cost 3 rd Party Purchases & Owns System Retains all grants, tax credits, depreciation & SRECs Has Roof Easement and provides system maintenance Pay 3 rd party for renewable power instead of Utility during Agreement period (at least 6 yrs.) Option to purchase system (buy out agreement) for small fee at end of period No Capital Cost, Operating Cost Savings during contract (and much higher with buy out) Copyright 2010 Dovetail Solar and Wind 73
