Presentation Transcript

  1. PMS is the host of Washingtonstate’sfirst full-size Community Solar Project.

  2. Even Jay Leno heard about it.

  3. The North Kitsap Herald made it into Leno’s weekly “Headlines” segment.

  4. Installation began in early January with the mounting system.

  5. The mounting system provides underlying support for the modules.

  6. Each community solar project is custom-designed to fit its host facility.

  7. Next is the racking system, which holds the modules in place.

  8. The racking system is made of galvanized steel.

  9. PMS has an optimal southern exposure.

  10. Once the racking was fabricated off-site, it took only two days to install.

  11. Wiring comes after the mounting and racking systems are in place.

  12. There were miles of wire!

  13. Now for the modules.

  14. One crate = 26 modules = approx 1,715 pounds .

  15. The modules have to be manufactured in-state to receive the full state incentives.

  16. Silicon Energy modules are manufactured in Marysville, WA.

  17. 390 modules were delivered in two separate loads two weeks apart.

  18. The modules aren’t fragile -- you could even jump on one.

  19. But careful placement is paramount.

  20. Distributing the weight puts less stress on the underlying roof structure.

  21. The state requires that modules be installed by certified electricians.

  22. It’s showtime!

  23. One module = 4 x 4 ft.

  24. One module = approx 66 pounds.

  25. One module generates an average of 195 watts.

  26. A team of two electricians can install about 60 modules a day.

  27. One row = 26 modules = 104 lineal feet.

  28. The “racking feet” provide a strong anchor for high winds, etc.

  29. The weather wasn’t always this nice!

  30. Silicon Energy modules have a unique self-contained wiring system.

  31. The last module was set March 2nd.

  32. Time for a massage!

  33. Air circulation gaps increase efficiency by reducing surface temperature.

  34. The modules are “strung” together in groups of 13.

  35. This project has 30 “strings.”

  36. And covers about 7500 square feet.

  37. Entire system installation took about 13 weeks (including inverters).

  38. Inverters convert the solar-generated DC to AC grid-tie-compatible electricity.

  39. The PMS project has 15 inverters.

  40. Inverters can be installed prior to or during the modules.

  41. The project was designed by Hans Frederickson of Frederickson Electric.

  42. State inspection was passed on March 10th. The PSE production meter was installed on March 15th.

  43. The system started generating energy and incentives at 11:59 a.m., March 15, 2011.

  44. THE END
