What uses a NiMH battery that is chargeable by a 3.5 KW solar panel and comes with 15-feet of attached wire? Well, you guessed that right. It’s the RainPerfect solar-powered rain barrel pump system. As the name aptly suggests, the solar-powered pump stores precious rain water in a barrel and then pumps it out to the surface.
Harnessing expertly the solar energy from the nearby areas, this little gadget has the capability to draw up to 100 gallons of water, armed with a pressure of 13 pounds per square inch.
No hassles of plugging it in for recharging the battery, and no problems of waiting for it to connect to a power source all the time. Leave it in the sun for some time, and the battery would be all charged up for use. Eco-friendly and easy to use, this is the best way to water your plants.
