We would like to install two solar-operated systems. <br /> <br /> <br />All water lines & drip tubes are already installed, however, there is no <br /> <br /> <br />electricity to operate a time clock and electric valves. <br /> <br /> <br />Using the current manual system, water is often turned on and forgotten <br /> <br />v <br />save ~ c .. . <br />, . <br />- ~.t <br />with . fe'''-' <br />o../{j-" <br />have <br /> <br />until water puddles on top of soil surface. The solar systems would <br /> <br /> <br />approximately 80,000 gallons of water each irrigation season. Along <br /> <br /> <br />water savings, we would reduce manpower (turning valves on/off), and <br /> <br /> <br />healthier trees (no more over/under watering). <br /> <br /> <br />I would like to convert two manual systems to solar, the converted sys- <br /> <br />tems would be on opposite sides of the park. I feel this would provide <br /> <br /> <br />a fair indication of the practicality of converting all manual systems <br /> <br /> <br />on the park (approximately 10 more) in the future. <br /> <br /> <br />I have discussed this project with Andy Walker with the Energy <br /> <br /> <br />Conservation Office. He felt it was an attainable goal and would be <br /> <br /> <br />fairly easy and inexpensive to construct and install. The project would <br /> <br /> <br />entail the purchase of a photo-photic panel, a battery storage system, a <br /> <br /> <br />low voltage time clock, low voltage valves and installation. <br /> <br /> <br />Assembly of solar unit and installation would be completed within <br /> <br /> <br />four months. <br /> <br />Cost <br /> <br />(2) Photo-photic collectors <br />(2) Batteries (Storage) <br />(2) Time Clocks <br />(2) Electric Valves <br />Control Wire <br />Metal Tubing (Support & security <br />for collectors) <br />Misc.
