<DIV>Is anyone aware of an RC club that has implemented a solar powered charging station for electric fliers ? My club has strongly supported the concept, voted to approve funds, and I would like to get hard data and experience from others on several system items. </DIV>
<DIV> </DIV>
<DIV>Two of our electric fliers/engineers have designed what they believe will be a scalable system, borrowing from their experience in powering wireless base stations and other similar applications. I wanted to compare their numbers to any hard experience from RC users.</DIV>
<DIV> </DIV>
<DIV>We lack good data on typical use per pilot. Our club is not all that Pattern heavy, but does have many electric fliers using 3s-4s packs in say the sub 4000 Mah size. For the most part, these systems power planes typically smaller than 40 size. Were I to guess, Eflite 480 size may be .typical or say average size plane.</DIV>
<DIV> </DIV>
<DIV>Any data and experience would be appreciated. Need data on :</DIV>
<DIV>a) the number of anticipated electric pilots and expected average weekly capacity used per pilot from existing solar powered systems </DIV>
<DIV>b) the size & type of the battery (deep cycle) used to store power - e.g. number of Mah and type - wet cell, gel cell or AGM, and the typical max discharge % anticipated; </DIV>
<DIV>c) - the recharge time (days or hours) to recharge the storage battery from normal max use drawdown; </DIV>
<DIV>d) the number and size of the solar panels used; and power output (amps) at say 16-17v range</DIV>
<DIV>e) the capacity of the charge controller used.</DIV>
