  1. 1. PVE and brownfields Construction  of Photovoltaic Power Plants (PVE) for Problem S
  2. 2. Introduction <ul><li>Name: Ján Otčenáš </li></ul><ul><li>Company: Solar Time, s.r.o., Slovakia </li></ul><ul><li>Member of SAPI </li></ul><ul><li>[email_address] </li></ul><ul><li>© 2011 </li></ul><ul><li>Photo by : Solar Time, SOLAR Bohemia, SPEMA Group </li></ul><ul><li>All information used in this document is published with the permission of the rights </li></ul>
  3. 3. Topics <ul><li>Main r easons for using the  brownfield sites in photovoltaics </li></ul><ul><li>Experience  in real models of  build ing  PVE on brownfield sites in examples </li></ul><ul><li>Important points in the construction of PVE on brownfields </li></ul>
  4. 4. Main r easons for using the  brownfield sites in photovoltaics <ul><li>Remov ing of the old e c ologic burden - the revitalization </li></ul><ul><li>Limiting environmental hazards and industrial pollution </li></ul><ul><li>Improving the natural environment and landscape </li></ul><ul><li>Photovoltaic is a financially acceptable solution for revitalizing the land and for use otherwise unusable land, as part of investment in commercial projects. </li></ul>
  5. 5. Experience in construction <ul><li>PVE Dolný Bar – swampy land </li></ul><ul><ul><li>Installed power: 1 MWp </li></ul></ul><ul><ul><li>Reference: Solar Time </li></ul></ul><ul><ul><li>In operation from 2010 </li></ul></ul><ul><li>PVE Želiezovce – municipal dump </li></ul><ul><ul><li>Installed power: 3 MWp </li></ul></ul><ul><ul><li>Reference: Solar Time, SOLAR Bohemia, Spema Group </li></ul></ul><ul><ul><li>In operation from 2011 </li></ul></ul><ul><li>PVE Dobšiná – asbestos quarry </li></ul><ul><ul><li>Installed power: 2 MWp </li></ul></ul><ul><ul><li>Reference: SOLAR Bohemia, Spema Group </li></ul></ul><ul><ul><li>In operation from 2010 </li></ul></ul><ul><li>PVE Dolní Rožinka – uranium pond </li></ul><ul><ul><li>Installed power: 4,3 MWp </li></ul></ul><ul><ul><li>Reference: SOLAR Bohemia, Spema Group </li></ul></ul><ul><ul><li>In operation from 2009 </li></ul></ul><ul><li>PVE Závadka – wastewater treatment plant area </li></ul><ul><ul><li>Installed power: 1 MWp </li></ul></ul><ul><ul><li>Reference: SOLAR Bohemia, Spema Group </li></ul></ul><ul><ul><li>In operation from 2010 </li></ul></ul>
  6. 6. PVE Dolný Bar swampy land <ul><li>Problems </li></ul><ul><ul><li>High level of groundwater </li></ul></ul><ul><ul><li>Swampy land with a solid bedrock at a depth of 1.6 m to 6 m </li></ul></ul><ul><li>Solutions for longtime stability of construction </li></ul><ul><ul><li>A dditional sleeves are added to anchor screws </li></ul></ul><ul><ul><li>Some anchor screws are long up to 3m </li></ul></ul><ul><ul><li>Inverters and other electrical equipmnet are placed higher than usually </li></ul></ul><ul><ul><li>All cables have protection to the water environment (waterproof certification) </li></ul></ul>
  7. 7. PVE Dolný Bar – močaristá pôda Before...
  8. 8. PVE Dolný Bar – swampy dump Flood before the completion of construction
  9. 9. PVE Dolný Bar – swampy dump Water level
  10. 10. PVE Želiezovce – municipal dump <ul><li>Problem </li></ul><ul><ul><li>The re exist higher values of chemical agresivity of environment </li></ul></ul><ul><li>Solutions </li></ul><ul><ul><li>For protection against chemically aggressive environment had been planned additional coating for zinced construction. Given the good results of geological survey additional coating did not realized. </li></ul></ul><ul><ul><li>We added the portion of soil surface in the thickness of 1.5 m </li></ul></ul><ul><ul><li>The re are running measuring for monitoring the degradation process of waste for risk reduction in operation. </li></ul></ul>
  11. 11. PVE Želiezovce – municipal dump Installed power 3 MWp
  12. 12. PVE Dobšiná – asbestos quarry example of the use the quarry after excavation
  13. 13. PVE Závadka – area WWTP wastewater treatment plant
  14. 14. PVE Dolní Rožinka – uranium pond example - unstable and toxic environment
  15. 15. Important issue s concerning the construction of PV on brownfield <ul><li>Geological survey with a sufficient number of probes to create maps of soil, static and chemical characteristics. </li></ul><ul><li>Proposal for a suitable anchoring structures and erosion and corrosion protection measures and improve mechanical stability </li></ul><ul><li>Develop ing a methodology for tracking changes in the ground during the operation of PVE </li></ul><ul><li>Developing crisis plans for operating the plant with respect characteristics of ground . P roposal solution of negative events for minimalize outage of production </li></ul>
