You will need to provide your own rain barrel, but the kit comes with a solar-powered rechargeable pump (3.5 watt solar panel included) that can send 100 gallons of water at 13PSI through your hose on a single 8-hour charge. The solar rechargeable (NiMH) battery allows for operation day or night.
It will connect to all standard garden hoses, and is adaptable to almost all styles of rain barrels. The $150.00 US price tag might put you off at first, but since you won’t be increasing your water or electric bills to use it, this could easily pay for itself by the end of summer.
