- 6. When sunlight is absorbed by these semiconducting materials, the solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity. Solar cells are made of silicon, the second most common element, exceeded only by oxygen. This process of converting light (photons) to electricity (voltage) is called the photovoltaic (PV) effect.

- 13. The vast majority of households in the U.S. receive 100% of their energy from the grid. Over 70% of all electricity in the grid is supplied from power plants burning fossil fuels like coal, gas, and oil. The U.S. currently ranks 2nd in coal consumption at over 500 million tons a year. 41% 6%20% 15% 16% Coal Oil Gas Nuclear Hydro Other
- 14. Every time you switch on your computer, washing machine, TV, or toaster, pollution is being created somewhere at the other end of the wire. This pollution has far-ranging consequences and contributes to poor air quality and climate change. Energy Information Administration 2009 International Energy Outlook

- 18. 30% Federal Tax Credit TVA Green Power Switch
- 19. Before 2009, the tax credit for installing a qualified solar system was limited to $2000. But now there is no limit. The credit is good for 30% of the system cost, after rebates. This tax credit is more powerful than a tax deduction. A deduction simply reduces your taxable income, while the credit reduces your tax bill directly. In plain English, a $10,000 tax credit reduces your taxes by $10,000. A tax deduction reduces it by only $1500 to $3500, depending on which tax bracket you're in. How the program works:
- 20. How the program works: A solar system is installed by a residential customer served by the TVA. TVA will purchase all of the green energy produced at 12 cents per kilowatt-hour above the retail rate AND any fuel cost adjustments. All new Generation Partners participants will receive a $1,000 incentive to help offset start-up costs. The customer is guaranteed payments for 10 years from the start of the agreement.
- 21. For You • Lower utility bills • Stable energy costs • Increased property value • Smaller carbon footprint • Setting a “green” example • Tax Shelter For Environment • Pollution free power • No greenhouse gases • No noise pollution • No mining or drilling • Less reliance on fossil/foreign fuels
- 22. •Price – competitive pricing through mass purchasing power. •Service – we’re not satisfied until you’re satisfied. •Quality – we treat your home as if it were our own.
Notas do Editor
- I want to preface this by saying a few things; Most importantly, I thank and applaud you for taking the time today to find what you can do to save money and the environment. The company was born with goals to educate and facilitate green energy systems. If either take place today then I will leave here a success. Second - this isn’t meant to be a presentation – feel free to stop me as I go through this but I’ll probably answer most of your questions before I am finished. Last thing is, RELAX – I’m not here to ask you to buy anything today. I want to share who we are with you and explore your options. If you decide this is a good fit for you then we’ll move to the next step. Fair enough? Alright! Let’s get started. AlterEco Systems is Middle Tennessee’s #1 source for clean renewable energy. I am one of the many representatives working for the company that enjoys the outdoors and is passionate about the environment. We envision a world that is free from dependence on coal, oil, gas and nuclear power. We are part of THE largest solar dealer network in the U.S. A growing team of certified contractors serviced by a master distributor.
- Our master distributor is Solar Energy Initiatives out of Jacksonville Florida. They were formed to execute a grass roots campaign, called “RENEW THE NATION”. Their mission is to help redeploy a portion of the U.S. work force and focus on reducing the world’s dependence on fossil fuels by distributing solar thermal and photovoltaic technologies. The staff at SEI are seasoned professionals in the renewable energy field. Employing licensed engineers and NABCEP certified installers. Their website is the most visited solar website in the world, currently receiving over 1 million "hits" per month.
- SEI has over 60 dealers in it’s network and provides its’ growing list of dealers with engineering, technical and product support. We have access to the largest selection of brand-name solar equipment at wholesale prices through mass purchasing power. AND we take advantage of the expertise of our extensive network of solar professionals. It’s a “win-win” for everyone involved, especially our customers and the environment!
- Our network of dealers have installed over 50 megawatts (that’s 50 million watts) of power. We have numerous residential and commercial project references available upon request – some from very high profile customers such as NASA and the U.S. Coast Guard. 3 megawatts of solar electric are currently being installed on 13 schools and we’re working on a large solar thermal project at Ft Campbell.
- Let’s talk about solar panels. We are the ONLY authorized G.E. distributor in Middle Tennessee. We also feature BP, Suntech, Sharp and Kyocera all with a 20-25 year warranties and 50 year life expectancies. The manufacturers know their product will be exposed to a variety of weather conditions so the panels are built to withstand the elements as best as possible - including hail up to an inch and a half in size at ninety miles per hour. The panels range in size depending on their wattage but are typically around 3’ x 5’ and about 5 inches deep.
- Solar panels are really quite simple by design. There are three layers inside a sealed frame with a translucent, antireflective cover. {Read captions} The more solar panels a PV system has, the more electricity will be produced which off-sets or even eliminates your electric bill.
- There are two ways to measure how much electricity your solar system produces. Most of the world uses what is called Net metering or using a single utility meter that “nets out” both what is “drawn” from the grid and what is “returned” or fed back to the grid. When a Net Metering system generates more power than the building is consuming, this surplus power is fed back into the utility grid, making the electric meter spin backwards. Basically, The solar panels collect the sun's energy and DC electricity is created. This electricity is then converted by an inverter to AC – the same type of electricity your home uses. The lights and appliances in your home then use this electricity and any surplus electricity is sent back to the grid.
- We are fortunate to live in the Tennessee Valley. The TVA offers a second option called Dual metering which uses two separate meters. One meter tracks the total energy consumed by the building and the other meter tracks total energy produced by the solar and fed back into the grid. Because this method accurately meters both production and consumption, different billing rates can be applied by the utility. TVA customers have the option to be paid a premium for their solar power generated while enjoying the normal rates for everything consumed.
- I often get asked how Tennessee compares to other states with consideration to the amount of sunlight. When you look at this map you can see that our exposure to the sun is only ½ hour less than the “Sunshine State” of Florida. Another interesting fact is that Germany, which has an insolation factor comparable to much of Canada, has more solar installed than any other country. So rest assured, solar works in Germany, and it works even better in Tennessee!
- Solar panels should be pointed in a direction that maximizes the amount of daily and seasonal sunlight that they receive. The solar panels should be facing generally South. Southeast and Southwest are also good choices. East and West facing are ok but we avoid northerly directions due to less direct sunlight.
- You should understand how the sun’s daily path throughout the year affects solar performance. In the winter the sun is lower in the sky. In the summer it rises more directly overhead. So the summer days are longer, there are more hours of sunlight and more electricity is produced. You may also be interested in knowing that solar panels are more efficient in cooler temperatures, and in a small way this helps offset a portion of the lost exposure in the winter months.
- How the sun hits your solar panels and any shadows created by obstructions are two of the most important design considerations for your solar system. Shading can be caused by trees, hills, buildings, chimneys, vents, and even power lines. Shading reduces the amount of power that is produced by the solar panels. Anything that blocks sunlight as the sun crosses the sky should be avoided. Mounting the panels on the ground can be another option when rooftop shading is a concern.
- Alright, now that you are an expert on solar panels, I’m going to “tug at your heart-strings” for a couple of slides but I promise to keep it brief. We don’t typically think of our home polluting or having an impact on the environment. However, homes and businesses consume two-thirds of the total U.S. electric demand. What’s worse, is that we are 2nd only to China in global consumption. We are leveling mountains to mine coal, polluting oceans with oil spills, contaminating land with nuclear fuel rods, destroying habitats and killing wildlife.
- There is plenty of evidence for and against climate change. Whether you believe in global warming or not, the fact is we are ALL emitting tons of carbon dioxide into the atmosphere. The scary part is that the world’s energy demand is expected to increase 50% by 2030. We are already feeling the economic and environmental costs of inaction. If we delay any longer, these costs will be felt even more. Not just by our generation, but our children and grandchildren as well.
- At a time when fossil fuel prices are volatile and global energy demand is increasing, shifting to power sources with free and limitless fuel makes sense. Reducing pollution through proven, reliable, carbon-free sources of electricity will help us solve the climate crisis.
- OK, I’m stepping down from my soapbox. Let’s talk about electric rates…………. they keep going up. I have not found any evidence or anyone who is predicting that electric rates will drop. If congress passes climate change legislation, cap and trade will impose even higher electric costs on U.S. families. On the other hand, the price of solar electricity does not go up because you pay a fixed price on the system and you know what the cost is ahead of time. Solar electricity is free after you pay for the system. It protects you against future rate hikes and you start saving money as soon as your solar panels are connected.
- Naturally, that brings up the next question. What does solar cost. On residential applications the cost is typically around $9-10 per watt. The total cost depends on the size of the system. The system size is dependent on many factors including your budget, available space and what percentage of your consumption that you want to offset. Our costs are minimized through mass purchasing power. The savings are then passed to you at $8 per watt. The GREAT news is that there are numerous incentives that reduce the cost and increase the return on investment.
- As consumers, we have become accustomed to buying energy from monopoly providers at pre-set rates and tiers with few options available. Once you own a solar system, the energy it produces is essentially free because there is no cost for fuel - EVER. At this point, you own a small utility company to serve your own energy needs, with almost no operating costs. Incentives, credits and rebates have made solar energy systems more affordable in recent years. These incentives reduce initial up-front investment and compensate the customer for energy produced.
- There are lots of great reasons to own a solar system. Renewable energy generation technologies have been adding clean, reliable power to the grid for more than three decades. It’s time to dramatically ramp-up the contribution of renewables to the energy mix.
