check our website for largo flying club in largo fl.we installed a solar power charging station and I would say its a quaqlified success,It has well and we will add a second set of panels so the postioning catches most of sun using 2 directions.it beats the heck out of using a car as the charger.unlike a gas generator the sun is free.but if you want a gas generator look into propane.I have a generator for my house and rather than using gasoline I use propane as my energy source as it lasts much longer and is cleaner.sadly it doesnt help abate noise..but checkout our club andagain it is a worthwhile project.
