This is another sick design on how to utilize rainwater with your own barrel system, this time the barrels are operated by a solar power generated panels. In case you are wondering what the solar panels are for, they are actually used to power up the pump for watering the plants.
This is the first project I’ve seen like this so far. The best features of this rainwater barrel system are its “water gauge” to check the water level and its ability to operate as is even if the water levels are low.
