Advantages Disadvantages

Low maintenance; no fuel costs; easyinstallation; reliability; unattended

operation; portable.

Higher initial costs; variable water delivery depending on sun intensity; higher return on investment depending on the

insolation of the installation .

Moderate initial costs; movable orportable; easy installation; requires certain system experience.

Requires regular maintenance and replacement of diesel:inadequate maintenance will reduce life expectancy; the higher costof fuel and the long-term fuel cost trend is upward; environmentalpollution of noise, smoke, and waste oil; requires an understandingof the installation environment.

Long life span; lower initial costs; no fuel costs.

High maintenance and replacement cost; difficult to purchase thereplace components locally; greatly influenced by season; requiresspecial tools to install; high labor costs; only works when wind conditions are adequate .

Lower initial costs; low maintenancecosts; no fuel costs; easy installation;reliable; simple

Rushing water is required.

Highest labor cost.Lowest initial costs; excellent mobility.

Solar Pumping System

Solar pumping system, is constituted by solar module array, combiner box, liquid level switch, solar pump etc. It aims atproviding solutions for the region that suffers water shortage, no power supply or uncertain power supply.

With the development of science and technology, People's requirement for the water supply output and water quality isgetting higher and higher. Also, they are taking the reliability of water supply system and environment protection intoconsideration. With the advantage of easy installations, low maintenance and operating cost, zero carbon emission,automatic running, and inexhaustible solar, the solar pumping system is gradually become the first choice for regions tosolve the water use problems.

■ The advantages and disadvantages between solar pumping system and traditional pumping system.

EASY INSTALLATION AUTOMATIC RUNNING REDUCED COST HIGH RELIABILITY ZERO CARBON EMISSION

Float level switchFloat level switch is designed in the principle of "Gravity and Buoyancy", which mainly includes the floating object, the high capacity microswitch, drive that can turn on or turn off the switch, and the three-core cable connected to the switch. Under the effect of buoyancy, thefloating ball rises or falls as the liquid level. When it and the water level forms a certain angle, the drive in the floating ball—high capacitymicro switch will output the signal of "on"/ "off", warning or the use of remote control.

Generally,the pump in solar pumping syste m is driven by the three phase AC motor. According to the actual sy stem demand andinstallation conditions,it can adopt different types of pumps. The most common in the solar pumping system is submersiblepump (deep-well pump),carrying water from wells or lakes and pouring into reservoirs or directly connecting to irrigationsystem.

Output line (load) reactors protect PDS solar pump controller against short circuits resulting from the motor insulation failure ,and also allow the motor to run cooler by “smoothing” the motor current waveform.They are recommended for any applicationsthat the length of wiring between the PDS solar pump controller and motor exceeds 50m. (Notes: the actual data and specificationmay be a little different.)

Test Conclusion:In Guangzhou, P.R. China, the average peak sunshine duration for many years is 3.53 hour. On the day of testing, the operating time of thesolar panels under equivalent efficiency and full rated power is 4.66 hour; the generating capacity of the tested systematic solar panels is24.49 kWh, and the saved electric energy is 23.4 kWh. The maximum transfer efficiency of PDS23 solar pump controller can reach 98%.

According to experience, the PDS23 solar pump system can generate 6764kWh electricity annually in Guangzhou, P.R. China and save6450 kWh electricity which equals to annual emission reduction of 6431kg CO ₂ and 194kg SO ₂ . The energy saving and emission reductionperformance of the system will be better in areas with more sun illumination.
