- มีราคาแพง ยิ่งระบบ AC แพงกว่า DC มาก หากการใช้งานที่ใช้น้ำน้อยทุนไม่เยอะอาจไม่คุ้ม หากมอเตอร์เสียหายจะไม่สามารถซ่อมแซมได้ และใช้กำลังไฟเยอะจึงอาจจะต้องใช้แผงโซล่าเซลล์เพิ่มมากขึ้น

Advantages of installing a groundwater filtration system That you need to know before installing !
1. Eliminate additives. Groundwater is inserted in the rocky soil layer.
2. Eliminate contaminants
3. Adjust the water condition. Water filtration will help adjust the water condition to meet more standards.
4. Bringing the bowels to use at all without being filtered That water may be full of contamination.
Advantages and disadvantages of each type of solar water pump
During these economic times, savings would be a great help to many lives to survive.
Model 1: Solar Centrifugal Pump [Solar Water Pumping System (Centrifugal Pump)]
strength
- It's cheap and easy to buy.
- Able to pump large volumes of water, about 1500-3000 liters / hour
- Easy to maintain Easy to find spare parts
weakness
- Suction wells up to 8 meters deep, except for twin jet centrifugal pumps that can pump deeper. And consumes quite high energy If a solar cell system is used together, several solar panels may be required to generate enough electricity.
Model 2: Solar cell submersible water pump, underground water pump [Solar Water Pumping System (Submersible Pump)]
It is a solar cell water pump used for submersible in the pond. or under the surface Suitable for pumping water up from wells that are dug quite deep.
Strength
- Absorbs very deeply There are many sizes to choose from.
- Get a lot of water
- Used to pump water up high Can pump water up to high water tanks
weakness
- Expensive, the AC system is much more expensive than DC. If the applications that use less water, not a lot of capital, may not be worth it. If the motor is damaged, it cannot be repaired. And uses a lot of power, so may need more solar panels
Model 3: Divo DC Solar Pump [Solar Water Pumping System (Divo Pump)]
Solar water pumps of this type are available in various sizes. Can pump water
strength
- cheap price
- Easy to use, hassle-free
- Can pump a large amount of water Small size, easy to carry
weakness
- Able to pump water at a small depth (up to 10 meters)
Style 4: Solar powered water pump with DC motor
It is a water pump in which the pump is combined with a DC motor and is transmitted by a belt. When connected to use, the suction pipe will be connected to the water.
Strength
- Suction depth of about 10 meters, transmission height above 10 meters.
- The pump is easy to buy, cheap, easy to find spare parts, the price of the DC motor is quite high.
- Use at low 400 rpm, pumping the amount of water worth the wasted energy.
Weakness
- There are often problems with heat in small machines. Easy to wear parts Heavy weight, difficult to move need frequent maintenance
