Building Solar Powered Rain Barrel Pump with Giraffe Tools

Video Description

Hi Everyone! I have been loving my rain barrel this summer, but lugging a watering can to water my plants was very time consuming. I finally added a pump and a hose to it, so now watering is a breeze! This is a 12v solar powered system as well, so I’m able to water my plants is completely off the grid. Here are the system components: Pump: https://amzn.to/3D6E0j9 Pump Filter: https://amzn.to/41vzK6W Solar Panel + Charge Controller: https://amzn.to/4fya12E Battery: https://amzn.to/41t9v1b Waterproof Junction Box: https://amzn.to/3VZWatN 1/2” to 3/4” hose Adapters: https://amzn.to/4fm6Byh Female to Female Hose Fitting: https://amzn.to/41w1tEA Inline Fuse: https://amzn.to/49AkZ4O Crimp Fittings: https://amzn.to/3OPoUBo Battery Spade Connectors: https://amzn.to/3ZC6poQ Giraffe tools was also kind enough to send their 82’ automatic ground mounted hose reel for this project!

Battery charge time math: Determine the battery capacity in watt hours (Wh): Battery Capacity (Wh) = Voltage (V) × Capacity (Ah) For my battery we get 12 V × 7 Ah = 84 Wh Estimate the charging time: To find the charging time, we divide the energy needed by the power output of the solar panel (I have a 20W Panel) Charging Time (hours) = 84 Wh 20 W Charging Time = 4.2 hours This assumes that the system is 100% efficient. In reality, the panel won’t always be generating a perfect 20W. But I get much more than 4 hours of full sun a day, so I can still charge my battery fully in a day. I hope you guys enjoy this video!
