  1. Solar for your Home and Business Earth Wind and Fire Energy SummitAddison TexasOctober 4, 2014 Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014

  2. Clean Energy Associates • Renewable energy programs • Education and training • Project development • Technical and market analysis • Advocacy • End-use energy consumers, Engineering and construction firms, Clean energy project developers, Utilities, Government agencies, and Regulators Independent consulting firm specializing in renewable energy, particularly distributed generation Services Clients

  3. Top distributed solar installer in Texas with offices in DFW+Austin+San Antonio • Successful contractor for recentSolarize Garland project • Goal: To be the be the best installer of the best solar equipment at the best prices for the best customers in Texas Our Recent Growth: 2009 – 32 kW 2010 – 104 kW 2011 – 242 kW 2012 – 1134 kW 2013 – 1676 kW 2014 – 2024 kW YTD Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014

  4. How Solar Integrates with a Home or Business Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014

  5. Solar Panel Technologies Types of Solar Cells • Crystalline Silicon (~88% of worldwide market) • Poly (~60%) • Mono (~18%) • Thin Film (~10%) • Cadmium Telluride (Cd-Te, ~5%) • Copper Indium Gallium Diselenide (CIGS ~2%) • Multi-junction, Nanocrystal, Organic, Plastic, Polymer, Quantum Dot, etc. (~2%) Advice • Don’t get too caught up in the latest developments and industry press • Best selling technology is so because it’s bullet proof • Longest warranties of any product (25 years) means you should look to strong companies with proven track records • And for good values Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014

  6. Common Inverter Technologies • Stand-Alone or String Inverter • Benefits – access, simplicity, strong track record, low cost • Drawbacks – slightly less efficient under certain circumstances, less granular performance data • Microinverters and AC Modules • Benefits – slightly more efficient under certain circumstances, highly granular performance data • Drawbacks – access, higher cost, finicky data integration • DC Optimizers • Benefits – slightly more efficient under certain circumstances, highly granular performance data • Drawbacks – access, higher cost, finicky data integration Advice • Don’t get too caught up in the latest developments and industry press • Best selling technology is so because it’s bullet proof Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014

  7. Using Solar Energy • Solar electricity feeds to home on your side of the utility electric meter • It flows to wherever it’s needed – lights, appliances, etc. • Utility-provided electricity will supplement to match your needs • If you’re generating more than you’re using, energy flows back to the utility Advice • Use it any way you like • Be aware of contractual relationships regarding “green” or renewable energy credits Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014

  8. Realizing Value for Solar Energy • Net Metering (many coops and munis) • Value (full retail, wholesale energy), rollover policies • Value of Solar (Austin only, so far), FiT or PPA (someday) • VOS: Utility charges you for all your consumption, regardless of whether it came from your solar or their wires; utility then credits you for all solar production, regardless of whether you used it in your home or exported it as excess energy to the grid • FiT/PPA: Utility contracts directly with customer for solar production • Inflow-Outflow Metering (competitive market, most common in DFW area) • Wires company meters inflows and outflows separately, passes data to retailers for billing • Retailers have no obligation to purchase or credit customer for outflows • Green Mountain Energy, TXU, and Reliant, and have buyback offers for residential customers • http://www.powertochoose.org/en-us/Content/Resource/Selling-Renewable-Power Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014

  9. The US Solar Market is Growing Rapidly… …and Growth is Becoming More Widespread Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014

  10. Solar Prices are Declining… U.S. …and areRelativelyLowin Texas Texas Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014

  11. Grid Parity… At $3.22/w-dc with no incentives http://www.ilsr.org/projects/solarparitymap/ Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014

  12. Grid Parity… At $3.22/w-dc with 30% Federal ITC http://www.ilsr.org/projects/solarparitymap/ Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014

  13. Solar Incentives are Declining… U.S. Texas 30% Federal ITC expires at the end of 2016 unless extended Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014

  14. Key Drivers of Customer Decisions Motivations for Going Solar Constraints Cash or credit rating Electricity usage Available roof area Shading Alternatives to solar • Environment, legacy, interest/hobby, network/peer effects, independence, conservation theology, simple economics • Economics • Price of solar • Price of traditional power (current and forecasted) • Asset and property value • Value of money • Incentives and tax credits (Utility rebates, federal tax credit) Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014

  15. Going Solar Choosing a Solar Company • Quality/Thoroughness of Bid • Credentials and Experience • Licensed electrical contractor • NABCEP certified installers • Knowledgeable/Attentive Sales Staff • Online Reviews Buying Solar • Cash – most common in Texas, straightforward purchase, cash payment then tax credit • Loan – can help match payment flow to energy bill reduction, customer owns the system • Lease – can help match payment flow to energy bill reduction, third party owns the system • Others (PPA, ESPC, PACE) The “10-2-10 rule of thumb” (for cash only) • 10c/kWh electricity price • + $2/w-dc net installed cost of solar (after rebates, tax credits, etc.) • Yields 10 year simple payback Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014

  16. Sample Economics – Oncor 2014 For sample purposes only – not a quotation! • System offsets 72% of customer’s electricity usage • $6,300 net cost after rebates and tax credits • Financed $1550 down yields net zero cash flow (monthly savings = monthly payment) Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014

  17. Some Final Thoughts Policy and Incentives • Tweaking the Economics • Rebates • Tax credits • Rate structures • Financing • Removing Barriers to Competition • HOA rules • Solar access • Consistent, predictable, efficient permitting processes • Big Questions and Issues • Declining incentives • Increasing electricity prices • Utility rate structures • Utility participation model Steve Wiese, Clean Energy Associates and Longhorn Solar for the Earth Wind and Fire Energy Summit, October 4, 2014
