Pico PV system introduction - Peter Adelmann

  1. 1. Wireless Power by Prof. Peter Adelmann / June 2011 University of Applied Science Ulm / Germany
  2. 2. Why does PV not grow faster in the field of rural electrification - e.g. cellphones have conquered a large market in shorter time
  3. 3. Is PV a second class electrification?
  4. 4. How about Telecom <ul><li>Europe was using at first Telegraph lines </li></ul><ul><li>Later Telephone landlines have been established </li></ul><ul><li>Latest technology is GSM type wireless telephone </li></ul><ul><li>Meanwhile also High Speed internet is available over GSM </li></ul>
  5. 5. Telecom in Africa <ul><li>In Africa telegraph and landline telephone have been developed only in big cities </li></ul><ul><li>With GSM it was possible to connect the country side of Africa to the global phone network </li></ul><ul><li>Internet connection is possible too </li></ul>
  6. 6. Is GSM a second class phone connection? Big part of Africa came immediately to the most modern solution!
  7. 7. How about Electric Power in Europe? <ul><li>Europe & America started to make grids in the late 19 th century </li></ul><ul><li>Since some years there is a strong discussion about the impact on the environment </li></ul>
  8. 8. How about Electric Power in Europe? <ul><li>Meanwhile Europe take high efforts to find alternatives </li></ul><ul><li>Many large PV systems are used for used to feed their energy into the grid </li></ul>
  9. 9. How about Electric Power in Europe? <ul><li>For applications for low power consumption and in a certain distance to the utility grid PV stand alone systems are the preferred solution! </li></ul><ul><li>PV is a clean and well working solution with the least cost! </li></ul>
  10. 10. How about Electric Power in Africa? <ul><li>Power grids are mainly available in big cities and areas with high density of people. </li></ul><ul><li>Population density is much lower than in Europe </li></ul><ul><li>Power demand as well </li></ul><ul><li>Solar radiation is much higher than in Europe </li></ul>

  12. 12. What would be the demand? <ul><li>At the moment kerosene and candles are used for light </li></ul><ul><li>Dry cell batteries are used for radio </li></ul>
  13. 13. What would be the demand? <ul><li>1l of kerosene cost at least 1$ and it last for one week or about 20h </li></ul><ul><li>1 klmh of light cost about 1$ </li></ul><ul><li>1 set batteries can operate a Radio (100mA) for 40h </li></ul><ul><li>To use 1h a Radio cost about 0,05$ </li></ul>
  14. 14. What would be the demand? <ul><li>Most people in Africa spend 5-10$ every month for this kind of energy supply </li></ul><ul><li>Lots of houses burn down due to the use of kerosene lamps </li></ul><ul><li>The light produce a smoky room and give just poor light </li></ul>
