Solar water pump – where can it be used?
A pump is usually used in a garden pond. This can be powered. But where there is no power connection, solar-powered pumps are the ultimate. In addition, they do not cause any running costs and are climate-neutral.
A pump that works with solar power can also be used in a stream. The solar watercourse pump is used to transport the water that has run downwards back up to the beginning of the watercourse. Here, too, solar variants make sense. It can also be used here without a battery since the stream does not have to function without the sun.
Mini ponds are particularly popular on terraces and balconies. Here, too, a water pump can provide oxygen-rich water, which allows plants to grow better. Combined with a small fountain, the mini pond becomes an eye-catcher in the seating area.
The collected water can be easily pumped out of a well or a large rain barrel if a pump with a solar connection is used. This usually consists of the solar module, a charge controller that regulates the flow of electricity, a battery that stores the energy, and a voltage converter. At the end is a socket into which the water pump is simply plugged. Various models are also available for this special case.
How does a solar-powered water pump work?
A water pump solar is equipped with the pump itself and a solar module. The solar module is either integrated into the pump or is supplied as a separate part. This is then connected to the pump with a cable and placed in a sunny spot. The solar panel captures the sun's energy, which is typically fed into a battery. The pump is supplied with energy via this, so that it is always on duty, not just in full sunshine.
Advantages and disadvantages compared to electric water pumps
The advantage of solar operation lies primarily in the environmental aspect, but also in the low operating costs, which are limited to occasional cleaning and maintenance. The disadvantage, of course, is that you are dependent on solar energy, although a battery largely compensates for this.
Install solar water pump – what should you pay attention to?
If a solar water pump is to be used, it is important to ensure that the solar module is placed in full sun or hung up there. The more sun hits the module, the more power the pump can produce. If there is no other way than for the solar module to be shaded, a powerful battery will help to compensate for this. In addition, when installing the solar pump, care should be taken to lay the cable between the water pump and the solar module skilfully.
Buy a solar water pump – you should pay attention to that
The following criteria should be considered if you want to buy a solar water pump.
The pump power is specified in watts. It should be in reasonable proportion to the amount of water in the pond. Therefore, most manufacturers indicate on the packaging for which pond size the solar water pump is intended. The size of the solar panel is also adapted to this.
2. Flow rate
The required flow rate also depends on the size of the pond. Here, too, there are recommendations from the manufacturers. The flow rate indicates how many liters are circulated through the pump per hour. If this performance is to be beneficial to the water quality, there should be a good relationship to the amount of water.
3. Funding level
The head is the key figure for the height of a water fountain. However, the maximum height is always specified here. This means that a certain size is reached when all conditions are excellent. If the sun shines less intensely, the water fountain of the solar water pump can be correspondingly smaller. If you rely on high performance here, you should use a larger pump or a larger solar area.
4. Battery capacity
The battery capacity of a solar water pump is also of concern. Because this indicates how much energy can be stored. Even if the solar module is large and captures a lot of energy, it cannot be stored sufficiently in a relatively small battery to then deliver it to the pump in the desired size.
Therefore, both should be in a good relationship in terms of performance, battery, and solar module. Sometimes sets are offered that contain both a pump and a battery and solar panel. Here you can assume good coordination of the sizes.
5. Cable length to solar panel
The cable length indicates how far the solar module can stand away from the pump. Long cables are an advantage here because then the position of the module can be chosen according to the solar radiation. The longer the cable, the less restricted the option you have with the solar panel.
Conclusion: solar water pump
Solar water pumps are a good way to combine the needs of garden design with environmentally-friendly aspects. Whether mainly for the various water fountains on the body of water or mainly for supplying oxygen to plants and animals – a solar-powered pump has many advantages and can compensate for the disadvantages of a powerful battery.
