There was a short discussion regarding price increase of energy over a twenty-year <br />period. <br />Member Kruse asked if a full life cycle analysis of the system could be done and at <br />the end of the life cycle what the cost of removal would potentially be. <br />Mr. Chris Psihos stated in regard to O and M costs when there is a traditional solar <br />array they are doing a straight O an M relationship on it. If the City were to look <br />at someone to maintain the solar array it would cost the City $300 to $500 per year <br />to pay for that and the savings on the solar array is around $5,000. The solar <br />equipment is warrantied for 25 years. When the equipment does need to be <br />disposed of, it is considered electronic waste (E -waste). The cost today is $15 to <br />$20 a panel and charge by the pound. In todays present economy the cost would <br />be around $10,000 to dispose of the equipment for a 40 -Kilowatt system. This <br />would be the same cost as what would be saved in the year 25. This would be a <br />swap in energy cost. He stated when they get past the point of transferring the <br />ownership over, the only burden is the continued insuring of the item and dealing <br />with the O and M and maintenance of the asset. <br />Mr. Rich Ragatz stated after 25 years the equipment will still have 80% of the <br />production output from the panels. He thought it would be doubtful that after the <br />warranty is expired the City would want to dispose of the panels. The City would <br />want to keep them up there because they are still producing or if the City did want <br />to dispose of the panels there would be someone to take the panels off the City's <br />hands. <br />Member Misra asked where the panels were manufactured. <br />Mr. Chris Psihos stated the ones iDeal Energies is using are made in Toronto <br />Canada and are one of the three manufacturers of solar panels in Canada <br />Member Misra asked what the life expectancy is of the solar panels. She <br />understood the panels were warrantied for 25 years. Assuming these are state of <br />the art panels, how much transition does iDeal Energies expect to see going <br />forward. <br />Mr. Chris Psihos stated solar panels today are basically all the same thing. He <br />explained how current solar panels create energy using sunlight. He stated this is <br />the same technology that has been around for forty years. He stated the warranty <br />is two tiered. <br />Member Kruse asked if the main risk is about not being able to predict the <br />electricity market. <br />Page 5 of 11 <br />
