Krofire House - Solar Power Station

• In August 2005 Krofire House had Photovoltaics Installed
  • Solar Energy globally is potentially equal to 1.54 peta kWh/year (that is 1,540 followed by fifteen zeroes)
  • 1.54 peta kWh/year is 15,000 times more than human electrical consumption in a year
  • Alexandre-Edmond Bequerel first discovered the photo voltaic effect in 1839
  • Photo-voltaic cells generate electricity from sunlight (of course) - even when it is cloudy. The Krofire Solar Power Station should generate well over 1000 units per year, roughly a quarter of our requirements
  • When we generate more than we need we sell the excess back to the Power Company at £0.05p/Unit plus the installation qualifies for roughtly two Renewables Obligation Certificates (ROC's) per year at about £49 each. ROC's are part of the Government's Carbon Trading scheme.
• The results so far:
  • Thru 2005, 2006 and 2007 we have been measuring the performance of this system.
  • Coupled with other (smaller) energy saving schemes (such as Energy Saving light bulbs) we have saved 36% off our direct electric Bill
  • What is more we are earning between £80 and £100 back off our supplier every year at wholesale prices
  • Conservatively we estimate that means the Solar Panels actually provide 50 to 60% of all our Electricity requirements
  • This is working ar better than our wildest dreams
  • Our Electricity Supplier (NPower) wanted to fit an Export Meter but failed. They claimed there was insufficient room in the Meter Box!
  • However, we have fitted our own "Electrisave" device (see www.electrisave.co.uk) which clearly shows the power being generate NET of our own needs. (Ironicaly it can't show the direction of Elecricity travel.)
  • At midday on any sunny day the Electrisave shows us pumping out over 1kw of power back into the Grid
