  3. Despitethe environment, global warming, national security and job creation, individuals will not make the move to renewable energies until it makes financial sense to do so. The time is NOW!

  4. This Region is Being Impacted by High Energy Costs.

  5. The Region’s Electrical Future? Rate Increases, Shortages and Brown Outs Since 2001 • BGE rates have increased 74%. • PEPCO rates have increased 78%. • SMECO rates have increased 157%. • This region now pays some of the highest electrical costs in the nation. • As of June 2009, this region pays $.15/kWh (13.6% higher than the national average. • Due to population growth and increasing production costs, electricity rate increases are forecast to continue into the future. Sources: Washington Post 2-3 & 7-1-08 Bureau of Labor Statistics 8-10-09 To reduce pressure on the grid, governments will increase incentives to encourage the switch to Renewable Energy.

  6. What is Being Done About it?

  7. The Federal Government Has Acted The solar investment tax credit covers 30% of PV system costs. The credit will be offered for a period of eight years (until 2017). Over $800 million of clean energy bonds will be authorized for renewable energy generating facilities. This alone is projected to create tens of thousands of new jobs. Congress Passes Investment Tax Credit (10-7-08) “… these tax credits have turned the solar industry from a small, cottage industry into an economic engine for America”Rhone Resch, President SEIA

  8. State and Local Governments Have Acted Prohibits unreasonable restrictions of solar energy projects. Requires 2% of state’s energy from solar by 2011 and 20% from renewable power by 2022. Establishes SREC program. Establishes Clean Energy Loan Program. Several counties now offer property tax credits. Maryland Solar Grant: Up to $10,000 for systems under 20kWh $1.25/ watt for the first 2,000 watts of capacity $0.75/ watt for watts 2,001 - 8,000 $0.25/ watt for watts 8,001 - 20,000 Maryland – Solar Related Incentives “We must do all that we can to secure Maryland’s energy future.” Gov. Martin O’Malley

  9. What are Renewable Energy Credits? Maryland has a program that offers Solar Renewable Energy Credits (SRECs). One SREC equals 1000 kWh of electrical generation. The value of an SREC is based on the Alternative Compliance Payment (ACP) schedule (2009 = $400, 2011 = $350). This is the penalty that utilities must pay to the Public Service Commission (PSC) for not meeting target goals. The value of an SREC in 2009 is about 60% to 70% of the ACP ($240 to $280). To benefit, homeowners must register their systems with the Maryland PSC and the PJM Interconnection GATS program. SREC Examples: A 3kW solar system generates about 3.6 SRECs per year A 5kW solar system generates about 6 SRECs per year. Selling of SRECs is another way that Marylanders can offset the costs of solar systems.

  10. State and Local Governments Have Acted $3.00 for each of the first 3,000 installed Watts: $ 9,000 $2.00 for each of the next 7,000 installed Watts: $14,000 $1.00 for each of the next 10,000 installed Watts: $10,000 Maximum Rebate (20kW system): $33,000 Approved incentives will be paid in advance of installation. District of Columbia Establishes New Incentives (2-2009) Washington DC joins the ranks of progressive states and counties offering incentives to purchase solar systems

  11. State and Local Governments Have Acted Residents and businesses can receive rebates for installation of PV systems. Residential Rebate: $2.25/Watt. Capped at 10kW. Business Rebate: Varies by size. $2.25/Watt for 3 to 10kW systems. Capped at 200kW. PA also participates in the AEC market (RECs). “Today marks another exciting milestone in Pennsylvania’s efforts to achieve energy independence…,”Gov. Ed Rendell Pennsylvania opens “Sunshine Program” (May 2009)

  12. The Incentives are Adding Up Federal Tax Credit: Tax credit covers 30% of system cost. District of Columbia: Grants based on system size. Range from $3,000 to $33,000. Maryland: Grants based on system size range from $1,250 to $10,000. Montgomery County – Property Tax Credit of $5,000 of system cost. Howard County – Property Tax Credit of $5,000 of system cost. Pennsylvania: Residential rebates based on system size range from $2,250 to $22,500. Net-Metering: All jurisdictions offer Net-Metering. Renewable Energy Credits (RECs): Provide additional incentives. Sales Tax Exemption: All PV systems are sales tax exempt. Federal and local credits, grants and rebates add up to make the case for going solar very compelling.

  13. Other Initiatives Exist The Solar America Initiative The aim of the SAI is to achieve parity with grid electricity by 2015. “By 2016, we expect solar energy to be the least expensive source for consumers.”Rhone Resch, President SEIA

  14. How is the Solar Electric Market Responding?

  15. Global Forecast – Installed Megawatts Source: BP Solar Installations are Soaring

  16. Global PV production & price comparison. Source: BP Solar Photovoltaic (PV) Prices are Dropping Production growth rates have exceeded 35% annually.

  17. With incentives, the solar market will continue to grow at impressive rates -- even in the current economy! Solar Economics and Prospects • The global PV industry has grown over 30% yearly for the past 15 years. • Prices of solar panels have continually dropped to around $4.00/W today. • Forecasts are for continued gains in PV efficiencies and cost reductions. • Government tax credits, grants and loans are playing a crucial role. • Given the high and increasing costs of electricity in the N.E., solar electric will likely become cost-effective here before it does in many other areas. A Summary of the Market

  18. How Does Solar Energy Work?

  19. Solar Electric Power - The Basics

  20. How Much Sunlight is Required? DC/MD/PA Average sunlight exceeds 4 hrs/day This area is considered a good environment for solar energy.

  21. What Direction are the Panels Pointed? Solar will not work for every location. Panels must be …… • Facing south • Angled to latitude • In the sun (no shade)

  22. What are the Configuration Options? • Grid-tied Represents 90% of solar PV market. Takes advantage of Net-Metering option. Simple system – modules, racks and inverter. Does not work when grid is down. • Grid-tied with battery backup Provides power when grid is down. Expensive - generators are often better option. Often used where grid interruptions can last several days and a generator is not feasible. Well suited for mission critical applications: medical, emergency services, computer systems.

  23. What are the Configuration Options? Direct power Ideal for remote locations that only need power during the day. Solar module(s) powers fan or water pump. No battery or controller needed. • Off-grid More complex and expensive. Often used in remote off-grid areas. Or, where electricity is inconvenient. Batteries require regular maintenance.

  24. Grid-tied PV System To AC Grid

  25. To / From AC Power Grid Grid-tied With Battery Back-up

  26. Solar System Components • Modules • Mounting systems and hardware • Combiner boxes and disconnect switches • Inverter

  27. Solar Modules Specifications (typical): Size: 60” x 33” x 1.8” Weight: 25 to 40 lbs Voltage: 17 to 36 vdc Watts: 170 to 205 Major Manufacturers: BP Solar Evergreen Kyocera Mitsubishi Sharp Solar World

  28. Roof mounts • Ground mounts Mounting Systems • Pole mounts Static Mount or Tracking Systems

  29. Combiner Box: Enables the wiring of multiple strings of modules into a single inverter. • Disconnect Switch: Disconnects power between array and inverter and between grid and inverter. Can be integrated into inverter. • Combination Box: Performs the function of the combiner box and disconnect switch. Combiner Boxes, Disconnects and Combination Boxes

  30. Inverters • Converts DC power from solar panels to AC power for home use or Net-Metering uses. • Grid-tied inverters must match the frequency of the power grid and are more expensive. • Many inverters offer integrated combiner box and disconnect. • Manufacturers: Exeltech, Fronius, Kaco, Outback, SMA, Xantrex

  31. What are the Costs vs. Incentives of Solar Energy?

  32. “Rule of Thumb”- Installed prices are around $8.00/Watt Typical System Installed Costs

  33. Electrical savings/M: 3kW = $60  Renewable Energy Credits (RECs) Other credits could apply  Interest on loans is deductible  Property value increases  Provides Hedge against rate increases Simplified System Costs with Incentives Maryland District of Columbia Pennsylvania Solar electric systems in this size would save 75 tons of CO2 over 25 years.
