Where there are no power lines, solar pumps offer a clean alternative to fuel-burning engines, generators and windmills. Now we know that it does not take long for a solar pump to pay off in terms of fuel and maintenance savings. SunRise is a new solar-electric submersible pump for deep wells and long pipelines. Until now, this range of solar pumping could only be performed efficiently by rod-driven jack pumps, which are extremely bulky and expensive. SunRise fills that gap.
Most solar pumps use centrifugal impellers, requiring much more power.
SunRise requires a smaller, less costly solar array. When the sun shines, the pump fills a storage tank. Most systems pump only during daylight hours and require no costly batteries. Batteries may be used if a large storage tank is not practical. SunRise uses a positive displacement sealed piston mechanism to force water up.
