Another application of solar photovoltaic is Solar Pumping. The solar pumping systems are of two types,
one is DC solar Pumping system and other is AC solar Pumping system. DC solar pumping systems are
small systems which are for domestic purposes, offices and irrigation of small lands up to two Acres. These
DC solar pumping systems are very reliable and cheaper. In this system the pump motor is DC motor and
one controller controls its operation which is MPPT controller responsible for smooth operation of the pump
without the need for batteries. The maximum flow with DC systems can be upto 10,000 Gallons per day with
maximum head of 200ft.
Solar AC Pumping system consists of AC Pump, Pump Controller and solar panels. These are big systems
of motor power varying from 2KW to 60KW and their up-front costs vary from Rs.1M to 20M. These AC
pumps are for all kinds of agriculture and big farming applications. The flow can vary from 10m3 per hour to
300 m3 per hour with head varying from 100 ft to 600 ft.
Solar Pumping is very specialized job and calls for high technical expertise starting from pump design &
selections to installation and commissioning of systems. The customers should buy systems from
professional companies and get installed from trained pump technicians.
Solar pumps are very economical if you compare operational costs with the conventional pumping system
working through Diesel generators or Utility Grid. The payback varies from three to seven years depending
on the type of system you are buying.
1. All solar module produces without any aberration or bubble.
2. Back sheet is TPT&PET, and the thickness is 0.3mm.
3. The thickness of EVA is 0.4mm,better than other company use 0.3mm or 0.35mm.We use new EVA
material, not the overdue, the overdue EVA will influence the performance and lifespan of solar panel.
4. New aluminum with 1.00mm thickness, high hardness, good impact resistance. Some company will use
bad recycle aluminum.
5. Tempered glass with 3.2mm has advantages of high strength, impact resistance,good light transmittance.
6. The solar cells made in Taiwan, high efficiency, low attenuation,the attenuation is less than 10% within 5
years and less than 15% within 10 years.
7. The junction box has good waterproof, good anti-aging,PV wire. The PV wire is good for anti-aging and
anti-corrosion, it's better than the normal wire.
8. Package by 7 layers thick carton, moisture proof and anti-cracking. Two pieces in one carton, easy to
delivery.
