I'm considering buying a solar panel, charge controller, battery, timer, and 12 volt pump. The controls and pump would be placed in a box under the deck along with a 30 gallon holding tank. I figure I'd need to run the pump about 2 minutes twice a day to dispense about 1/2 gallon of bleach daily to keep my free chlorine in the 3-5 ppm range once my stabilizer is up to par. I'm just not sure how to size the panel and battery. Any advice?
