1. Solar Energy Solutions Hans Albee – ReVision Energy

2. Maine’s most experienced renewable energy installer More than 3,000 solar systems installed Founded in Liberty in 2003 - roots from The Green Store Offices in Liberty, Portland and Exeter 65 employees and growing In-house design, installation and service of solar energy systems PPA funding/project development Who is ReVision Energy?

3. Hopeful Solutions Solar thermal Solar electricity Energy audits and insulation improvements Air source heat pumps Heat pump water heaters Wood stoves and boilers Pellet stoves and boilers

4. In one hour, enough solar energy strikes the earth’s surface to supply all the world’s energy demands for a year Why Solar?

5. Worldwide Solar Insolation

7. Grid-Tied Solar Electricity

8. Grid-Tied PV Maintain connection to the power grid Net-metering allows for system to earn credits when a surplus is generated/sent back to the grid Systems are long lived (30+ years) Require little to no maintenance and no batteries! Offset as much of electric bill as you like Use as fuel for space heating, domestic hot water, even charging an electric car Available government incentives and grants Affordable financing option on installed systems

9. How Does Grid-Tied Solar Electricity Work?

20. Solar Thermal

21. Designed for everyday use – dishes, laundry, bathing Designed to provide 70% of a home’s year-round domestic hot water demand, offsetting 150-300 gallons of oil Systems are long lived (20+ years) Require regular maintenance (3-5 years) Available government incentives and grants

27. What makes a good solar site?

28. 155˚ 245˚ 196˚ 196 degrees magnetic is ideal ‘solar south’ - acceptable range is 155 to 245 degrees Compass Orientation

29. Collector Installation Angle For GTPV, nearly any angle is acceptable

30. Saying Goodbye to Oil

31. The Mayberry’s Story: Getting Rid of Oil Figured roughly 500 gallons of oil a year just for domestic hot water alone Total oil usage was around 1,200 gallons in mild years Installed solar water system, including tank with electric back-up Sold their boilermate on CraigsList and shut off the oil boiler Average 6 tons of wood pellets between the two pellet stoves for a winter period Haven’t purchased any oil since

32. The Mayberry’s Story: PV Electricity purchased in the 12 months prior to solar installation: 13,899 kilowatt hours Total CMP costs during the 12 months prior to solar installation: $2,106.18

33. The Mayberry’s Story: PV Electricity purchased in the 12 months after their solar installation: 6,561 kilowatt hours Total CMP costs during the 12 months after their solar installation: $962.54 Total electric savings : $1,143.42, or 54%
