Solar Power |

Basic Process:
When sunlight shines on to solar panels (which are composed of photovolatic (PV) cells), the light is transformed into DC electricity. That DC electricity is then converted to the AC electricity that is used throughout your home.
During the day, if the PV system generates more electricity than is used in your home, that extra electricity is fed into the utility grid and is credited on your electric bill. When this happens, you will actually be able to see your utility meter spin backwards. At night, electricity is automatically drawn from the grid, as it is now, to provide your home with the power you need.
Solar Panel Installation
|
Solar photovoltaic panels can be installed on many different types of roofs. Panels can be flush mounted as well as tilted up When ever possible it is best to install solar panel mounts while a home is being roofed. Solar mounts "flashed-in" during the roofing process will eliminate any possibility of roof leaks.
It is also much easier to locate rafters when the roof is off. All mounts need to be secured onto the roof with stainless steel lag bolts bolted through into rafters.
Having structural attachment points "flashed-in" is the most wise method of installing solar panels, and the future cost of removal and re-installation of solar panels can be avoided for decades.
Composition shingle roofs are the easiest to work with. Tile roofs are more challenging and carrying solar panels across them can be like walking on egg shells.
STEP 1.
Use solar panel mounts to structurally attach solar panels to a roof. The mounts are secured before the new roof is applied. For existing roofs we utilize "TileTrac" mounts.
|
STEP 2.Align mounts on top of rafters, then pre-drill with a pilot bit to avoid splitting the rafters. The rafters can be found with a stud finder. Use a chalk line or laser sight to keep the mounts in a straight line.
STEP 3.Secure the mounts to the roof with stainless steel lag bolts. The roof on this house was brand new but looked sloppy, so a new layer was applied around the mounts.
STEP 4.Metal flashings were placed over the mounts and the layer of roofing was hot-mopped around the mounts. Metal rails are secured to the posts with 3/8' stainless steel bolts.
STEP 5.Next we install pre-assembled and hard wired solar panels in groups of 4.No "quick connections" are used on our wiring. This array holds 20 of a total of 40 Siemens panels installed.
STEP 6.After the solar panels were in place a layer of reflective roof coating was applied to the roof.The final step is to run the conduit to connect the panels to the inverter. This installation is a low profile, unobtrusive, clean green energy making machine

Congress UpdateCongress will be in recess until after the election season. It looks increasingly likely that they will return for a lame duck session in November and will possible debate a second economic stimulus package.
SEIA Names 2008 Solar Champions of the YearSenators Maria Cantwell (D-WA) and Gordon Smith (R-OR) have been named SEIA's 2008 Solar Champions of the Year for their leadership over the last year in extending and improving the solar tax credits as well as other issues related to solar. Their commitment to expanding the solar market in the U.S. has been vital to all of SEIA's success over the past year and we look forward to working with them in the future. Senator Cantwell delivered remarks at Solar Power International (SPI) last week in San Diego, detailing where solar policy is going post-ITC. Her speech as well as other video from SPI is available here (Senator Cantwell's remarks, with an introduction from Rhone Resch, can be found in the video titled "Closing Plenary Session" beginning at 1hr, 9min).
SEIA PAC Hosts Reception in San DiegoSEIA hosted a PAC event at Solar Power International in San Diego last week. This event, which was hosted at the Omni Hotel, raised more than $15,000. Thank you to everyone who attended and donated to the PAC. SEIA's PAC will help strengthen the political voice of the solar industry and continue to grow the solar marketplace. If you would like to donate to the PAC, contact Matt Horowitz at mhorowitz@seia.org or Suzanne Farris at sfarris@seia.org. You can also donate to the PAC directly at http://www.seia.org/cs/seia_pac.
Division Meeting Summaries OnlineSEIA's three divisions - solar thermal, CSP, and PV - each held meetings in San Diego. If you were unable to attend your division meeting, a summary will be available by Wednesday on the specific division's page in the Member section of the SEIA website. For a summary of Solar Power International, see the Industry Meetings section below.

U.S. Solar Field Foresees Cost Parity with Coal, Gas
Reuters – October 16

"U.S. producers of solar power will no longer need federal subsidies within eight years because by then solar power will cost less than electricity generated by conventional power plants, industry players said this week."
Oregon Solar Plants Power Up, Utilities Prepare to Power Them
New York Times – October 16
http://www.nytimes.com/external/gigaom/2008/10/16/16gigaom-oregon-solar-plants-power-up-utilities-prepare-to-12240.html
"It's been a pro-solar week in Oregon. German solar maker SolarWorld is set to open its 480,000-square-foot semiconductor plant in Hillsboro today, and Sanyo broke ground at its 861,000-square-foot factory on Wednesday at the Salem (Ore.) Renewable Energy and Technology Park."
Energy storage: How solar can always meet demand
RenewableEnergyWorld.com – October 15
http://www.renewableenergyworld.com/rea/magazine/story?id=53861
"Thermal energy storage provides a number of significant commercial benefits to the operation of a concentrating solar power (CSP) facility. Storage allows the plant to be optimized to address the peak load profile of a utility; it provides the operational flexibility required for the CSP facility to be more competitive and create the most value as a project; and it is a zero emission solution to the eternal 'variability' question that dogs much renewable generation, particularly when it is grid-connected."
Schwarzenegger: Solar Can't Be Stopped
