Solar rain barrel pumps can provide a low-cost and environmentally friendly way of turning rainfall into a ready-made water supply for your home and garden. By attaching a solar pump to your rain barrel, you can ensure pressure in your water supply even when the water levels in your barrel fall lower than the output spout. Easy, convenient, and completely self-powered, these pumps prove that caring for the environment doesn’t require one to sacrifice quality or convenience.
With many competitive options on the market, it doesn’t take much for you to harness the rain and the sun in order to make the most of your environment. Read on for several brief reviews of the top products on today’s marketplace, as well as several choice pieces of advice on selecting a pump for your rain barrel from the wide variety of possible features and options.

Perfect Solar Powered Rain Barrel Pump System by Rule
Best Solar Rain Barrel Pumps Reviews
1. Solariver Solar Water Pump Kit
A proven name in solar rain barrel water pumps, Solariver provides time-tested quality at a competitive price. By utilizing the power of the sun’s radiation, this water pump can provide water pressure to your garden hose without being dependant on batteries or electrical outlets. This high-powered system can pump up to a hundred gallons on a single charge. Easy to install and environmentally friendly, this pump can attach to a standard hose and be ready to meet all outdoor water-pumping needs.
2. Perfect Solar Powered Rain Barrel Pump System by Rule
Slightly cheaper than Plow & Hearth’s solar rain barrel pump, Rule’s Perfect Solar Powered Rain Barrel Pump offers similar qualities with less durability and water pressure. If you’re looking for a budget pump to power your sprinklers or water a small garden, however, the Rule System is a great option to consider. Simply be aware that what you save in dollars, you’ll eventually pay for in terms of lifespan and overall quality.
3. Sunnydaze Solar Water Pump and Panel
Equipped with a solar battery capable of pumping up to 100 gallons on a single charge and capable of providing up to 132 GPH through almost all standard garden hoses, this solar powered rain barrel pump from Sunnydaze is a popular alternative to expensive, top-of-the-line products like Solariver. In addition, though this pump is slightly more expensive than the Rule alternative, it also tends to be more reliable, making it a popular compromise between the need for quality and the need to stay within budget.
4. LEDGLE 5W Solar Fountain Pump Garden Water Pump
Like the other items on our list, this Ledgle solar water barrel pump runs on a rechargeable, nickel-metal hydride (NiMH) battery and can pump up to 100 gallons of water through most standard garden hoses at 380 liters per hour on a single charge. In terms of specs, the Ledgle system doesn’t do much to stand out from the pack. Plus, its customer service and user interface leave something to be desired, placing this product at the bottom of our list compared to its competitors.
How Solar Rain Barrel Pumps Work
Like solar water heaters, solar rain barrel pumps allow on solar cell technology in order to recharge and power themselves using only the energy of the sun. The small solar cell and associated battery relies on a phenomenon known as the photovoltaic effect–the creation of voltage and an electrical current upon exposure to light–to harness the sun’s energy, store it away, and access it later in order to power the skimmer’s motors and sensors. The solar cell–the dark panel at the top of a solar pool light–harnesses the energy of the sun’s rays and converts it into direct electric current.
This works because the solar cell is made of layers of silicone and specific chemicals that create electrical potential (a.k.a. voltage) via alternating pockets of positively charged space and negatively charged, reactive electrons. When high energy waves of light cast by the sun strike these electrons, they are discharged from their positions and pushed into the cell’s positively charged spaces, ultimately creating an electrical current. Much like dominos, the initial movement of electrons down the electrical gradient triggers a chain reaction–electrons transfer their energy to one another on down the line. The solar cells channels this induced current through wires connected to a battery, which stores the gathered energy in the form of yet another potential difference. When you turn on your solar rain barrel pump, this energy is accessed in order to power the pump and move the water collected by the rain barrel out into the world (perhaps into your solar bird bath).
In conclusion, a solar powered pump for your rain barrel can be a solid investment for those looking to cut down on the costs and headache of using municipal water supplies to care for gardens (especially when combined with these solar pond aerators), wash cars, or water lawns. Additionally, solar rain barrel pumps are self-sufficient and environmentally friendly–a refreshing change from more traditional lawn care strategies. Using the natural properties of the sun and rain water, solar rain barrel pump systems provide a low-stress way of caring for your lawn, garden, and solar fountains. With a wide variety of reliable, high quality options on the market, you can be sure to select the solar rain barrel pump that best suits both your requirements and your budget.
