You for coming!


Financial Payback

Payback on solar isn’t the most important thing…

… it’s the only thing the vast majority of potential solar purchasers care about


Right or Wrong

95% see energy as a commodity Few will pay more Must meet them on their terms:

$$ FINANCIAL! $$


Attractive Economics

PV systems can be financially attractive to customers using > $100/mo in CA

Attractive defined as: Rate of Return > 9% Property Value Increase > System Cost Bill Savings > Loan Cost


Payback AnalysisWhy is it Needed?

If we’re going to put solar on every roof, it needs to make $ense.

Cash Flow

Compares the savings on the utility bill with the cost of financing the system

At today’s rates (~8%) and including rebate benefits, cash flow is often positive immediately Cost of borrowing < savings on electric bill Stabilizes long term utility costs

Watt’$ the Resale Value?


Increase in Appraisal Valuation

Solar electric systems add value to homes by:Reducing or eliminating electric energy

operating costs


Reduced Cost Increases Value

$1000/year savings in a residence. Nevin in the Appraisal Journal states: ‘The

increase in appraisal value for a home is about twenty (20) times the annual reduction in operating costs due to energy efficiency measures.’

Electric bill savings: $1,000 per year -- Increased appraisal value: $20,000.

Article refers to residential only. Use “Cap Rate” for commercial value.


The Rational

The $1,000 not spent on electricity, is available to be spent on an equity loan payment…

… at no net change in the cost of living.

Pacific Gas and Electric Company DISTRIBUTION Billing INTERCONNECTION AGREEMENT FOR Customer-Generator NET ENERGY METERING FOR Business Customer Center RESIDENTIAL AND SMALL COMMERCIAL SOLAR OR WIND REFERENCE ELECTRIC GENERATING FACILITIES OF 10 KILOWATTS OR LESS Current Acct No. ______________________

DECLARATIONS

Mr. Sunny Customer ("Customer-Generator") and Pacific Gas and

Electric Company, also referred to as “Utility”, referred to collectively as "Parties" and individually as "Party," consistent with, and in order to effectuate, the provisions of Sections 2827 and 2827.7 of the California Public Utilities Code and Pacific Gas and Electric Company’s electric rate Schedule E-NET (“E-NET”), enter into this “Interconnection Agreement for Net Energy Metering For Residential and Small Commercial Solar or Wind Electric Generating Facilities of 10 Kilowatts or Less” (“Agreement”)1. This Agreement applies to the Customer-Generator’s generating facilities identified below with the specified characteristics and generating capacity, and does not allow interconnection or operation of facilities different than those described. Accordingly, the Parties agree as follows: 1. DESCRIPTION OF CUSTOMER-GENERATOR’S SOLAR OR WIND ELECTRIC GENERATING

FACILITY (“Facility”) Project Identification Number: __________________________

(Utility Log Number)

Interconnected Equipment:

Table 1. - List of generating equipment interconnecting with Pacific Gas and Electric Company’s Distribution System with, or without, an inverter. (For those generators interconnecting without an inverter, write in “N/A” in the right three columns. If an inverter is shared by more than one generator, write “shared” on the same line as that generator under the manufacturer column and do not enter the inverter rating. Attach list of additional equipment if applicable.)

Type of Generator Generator Manufacturer for Inverter Inverter Rating (Solar / Wind / Rating Inverter used with Model (watts) 2

Hybrid) (watts) Generator Number 1

Generator Rating: =# of inverters * Inverter Rating 2Inverter Rating =# of inverters * Inverter Rating * Inverter CEC efficiency

It is possible that the inverter rating might be the nameplate rating, rather than the CEC rating. For example, the IG3000 might be 3000W instead of 2700W.

1 Additional forms are available upon request by telephoning 415-972-5676 or on PG&E’s website at http://www.pge.com/gen).

2 The inverter rating equals: (the CEC efficiency for each installed inverter) TIMES (the nameplate rating, in kW, of each inverter). The CEC efficiency is obtained on the CEC website at http://www.consumerenergycenter.org/erprebate/eligible_inverters.html as listed on the date the application is reviewed. Enter the total of all inverter ratings for multiple inverter installations in the Table above.
