I want to run the pump continously. The pump is 328 watts / 15 amps / 115 volts how many panels / batteries do I need?

    It sounds like your current pool pump operates using AC power, which can be configured with solar panels, batteries, charge controller and inverter, but this arrangement will tend to be less efficient than a DC solar pool pump which can be found in our solar pool section. Without knowing the specifics of the pool pump, a pump requiring 328 watts per hour will require 7872 watts for a 24 hour period. I’m not sure this kind of application will be practical considering you will need about 32 solar panels and many more batteries to operate the pool pump for a 24 hour period. The operating cost for the AC pool pump is probably running in the neighborhood of $20 – $30 per month or $240 -$360 annually. With all things considered, visit the solar pool pump section of SolarTown and review the DC solar pool pumps. Solar Pool Pumps require less energy to operate and in this situation will be probably a better fit for your configuration. Solar pool pumps are also built to work with solar panels so the final number of modules will be substantially less depending upon your runtime.
