A:  When you do not have a grid connection (or an unreliable one), you’d better to have a solar water pumping system. Even if you have a reliable grid connection, it still makes financial sense to pump water using solar power. Your saving comes from electricity and/or diesel savings. When both the grid connection and solar power are reliable, we suggest you to use our Solar Submersible Pumps AC/DC Hybrid,  Solar Ground Pumps AC/DC Hybrid.

A: The advantages of solar water pumps over conventional electric pumps are given below:

• Solar water pumps do not require any fuel or electricity to operate.
• Does not get affected by power cuts, low voltage, single phase problems or the motor burning.
• Can be installed in remote areas where electricity is unavailable or diesel is difficult to procure.
• Incurs low maintenance costs as solar water pumps have fewer moving parts as compared to a diesel-powered pumpsso there are less chance of wear and tear.
• No lubricant is required for operation and hence no chance of water/soil contamination due to the lubricant.
• Easy to operate.

A: The price depends on a wide variety of factors. To size and select a suitable water pumping system, you need to know the following information.

1. What is your source of water?
2. How high and far are you pumping to?
3. The amount of water you wish to pump per hour.

A: There are several different types of solar-powered pumps depending on how they have been classified. But primarily there are 4 types of solar water pumps:

• Submersible pumps and Surface pumps,
• DCpumps (Direct Current) and AC pumps (Alternate Current).

Submersible pumps: A submersible pump is “submerged” under water, which means the pump itself always needs to be under the water to work. These are mostly used for pumping from boreholes and wells.

Surface pumps need to stay above the water, a pipe is connected which “sucks” the water from a nearby water source, mostly a pond, lake or river.

DC pumps run on Direct Current, which means the solar power (which is also direct current) does not need to be converted to AC-power. DC-powered pumps are generally 20-40% more efficient than AC-powered pumps.

AC pumps operates on Alternating Current, that’s grid electricity.

Luck Elephant has pumps which can use both DC as well as AC power as their input. Besides solar-power, a hybrid power supply can be given to the pump. The pump can be connected to the state electricity grid or a diesel generator set after making an easy and automatic adjustments in the controller. Check out our Solar Submersible Pumps AC/DC Hybrid,  Solar Ground Pumps AC/DC Hybrid, Solar Swimming Pool Pumps AC/DC Hybrid.

A:   The selection is based on the groundwater level and the water source. In the case of a borewell with a water table deeper than 10-15 meters, a submersible pump is used. If it is an open well, pond, river, etc, then using a surface pump is better. Also, the surface pump is installed when the water level is less than 10 meters.

A: Our solar water pumps are made for Agriculture irrigation, Community or Household water supply, Livestock, Aquaculture & Fish farming, Municipal river & pond aeration oxygenation.

Selecting the right pump depends on what you’re creating, where you live, and how high that you need the water to travel vertically.

A:   Installing a solar water pump is not complicated. Lucky Elephant’s solar water pumps have ‘Mistake-Proofing’ or ‘Inadvertent-Error Prevention’ design. In Addition, Lucky Elephant’s solar water pumps have ‘Error-Tolerant Design’ which protects your devices during installation. Besides, every solar water pump has a user manual to help you install.

A:   Under normal service conditions, the unit is designed for a 7-10 year service life. But during this period, the pump may require periodic servicing.

A:  Yes! It’s actually radiation from the sun, rather than temperature, heat or direct sunlight, that enables solar PV panels to generate electricity.

Solar panels in hot sunny countries are bound to gather more energy, but don’t be fooled into thinking that they won’t work well in cloudy days. They don’t need constant direct sunlight to work and can still generate electricity when the weather is cloudy.

A:  Normally, a storage tank or cistern is integrated in the design of a solar water pumping system. The storage tank acts as a “battery”. When the sun shines, the tank is filled up, when it is cloudy or dark, water can be used from the tank which is placed at a high point.

Storing water in a cistern or tank has many advantages. It’s less expensive and more efficient than storing power in batteries.

Using batteries may seem like a good idea, but they have a number of disadvantages in pumping systems. 

① They reduce the efficiency of the overall system. 

② They are another source of problems and maintenance.

③ They add cost to the system.

A: The answer might be complicated. Here’s why.

If you can store the water you have pumped up, that will act as your battery. Only in case the yield of your borehole is limited and you have a high water consumption which requires you to also pump at night, you should consider integrating batteries.

And if the water pump has a grid-tied connection, you don’t need a battery backup system. However, it will save you money every month to have a battery backup system compared with the use of grid-tied electricity. 

The reason being is that a battery backup system allows you to harness all the energy your solar array produces. That’s free energy (aside from the cost of the array and batteries) vs. the cost of buying electricity from the local utility company.

The question is, “do you want to pay the local utility to run your water pump?” Generally, the answer is no. With a battery backup system, you gain more self-reliance and energy independence.

2. Backup solar battery system compared to grid connection, it can achieve energy freedom without ongoing cost

A:  As long as the solar panels are mounted with a pitch of 10-15 degrees, most of the dirt should be washed off by the rain. When the solar modules are particularly dirty, and no rain is expected due to a dry season, it can be smart to clean the solar panels though. Cleaning the solar panels should be done with a soft cloth (to protect the coating) and ideally demineralized water.

A: The amount of water you need depends on many factors. These include:

The size of the farm

The crops you are growing

The irrigation system you use (drip irrigation is most efficient)

The soil type

The climate

Together with the solar water pumping company you select, you can probably make a good calculation.

But generally, a 2 HP (appx. 1500w) pump can cater to about 2 acres of land. But these data vary depending on the groundwater levels and the type of irrigation required for a particular crop.

A:  Well, for starters it’s a renewable source of energy, so unlike coal it won’t run out. Plus solar energy is environmentally friendly because it doesn’t generate green house gases. Renewable energy technologies will help you reduce your carbon footprint, meaning you’ll personally be doing your bit for the environment.

A: As the solar market has grown, the number of solar manufacturers has increased. This gives you great variety and choice but can also make your decision-making that bit harder.

A: The maximum vertical head (MVH) is how far the pump is capable of pushing water upwards. Even though MVH might not be as important for bird baths or a fish tank, the vertical height does matter if your water pump is at the bottom of a fish pond or placed in a deep well. 
Both surface and submersible water pumps must be placed to account for MVH, otherwise, the water will not reach as high as you want. For instance, if your garden pond is six feet deep and your solar pond pump can only reach two feet of height, then you will not have enough water power to even make a ripple.

A: The maximum flow rate (MF) capacity is the amount of water that a solar-powered fountain pump can move within a certain amount of time. Commonly measured in gallons per hour (GPH) or gallons per minute (GPM), the max flow rate becomes important if you need a lot of water flow. If a pump runs too slowly, for example, you might not be able to keep a tank full or store enough water.
Even so, not every project needs a powerful pump. If you have a smaller project in mind, such as a birdbath or small pond, you likely don’t need as much water flow as an irrigation or sprinkler system.
