Solectrogen Solar-Powered
Pump Packages
The Solectrogen solar powered swimming pool pumping packages utilize
the sun's energy to operate the filtration pump, eliminating the need for
utility power, thereby saving the cost of the electrical energy normally
used by the AC pool pump. It also eliminates the need for controls and
timers. Because the pump is directly connected to the output of the solar
panels, it starts running shortly after sunrise and continues until shortly
before sunset. Naturally in the summer when the days are longer, the pump
runs for more hours per day and, in the winter, for fewer hours per day.
On cloudy and overcast days the pump runs more slowly, pumping less water
through the filter.. All this makes the Solectrogen pool pumping system
a natural fit for swimming pool filtration, because algae growth is accelerated
in the summer when the days are longer and the water is warmer, requiring
more filtration capacity, while in the winter when the days are shorter,
and the water temperatures are cooler, the algae growth is retarded and
the pool requires less filtration. Most conventional pool filtration systems
have a timer programmed to run the pump for four hours per day in the summer.
Since the Solectrogen system would run the pump six to ten hours per day
in the summer (depending on location), the pump size required for the filtration
of a given size pool may be reduced by 40 to 60 percent. In other words,
if a 1.5 HP AC pump is required, a 3/4 HP Solectrogen pump can accomplish
the same amount of filtration because it would run for longer hours. Similarly,
a 2 HP AC pump can be replaced by a 1 HP Solectrogen pump and a 1 HP AC
pump by a 1/2 HP Solectrogen pump. Our tests show that cartridge filters
are most suitable for use with the solar powered pumps, somewhat oversized
sand filters do well also, but the diatomatious earth (DE) filters are
not suitable because they produce more pressure drops, requiring larger
pumps. The pump volute and casing are constructed of reinforced engineered
plastic making them light-weight and corrosion-free. A trap is built into
the pump, providing easy access to its strainer basket. The permanent magnet
DC motors are highly efficient and run at 2500 RPM at the design voltage
of 90 VDC. The Solectrogen Pump Packages are available in three sizes:
1/2, 3/4, and 1 HP, each with appropriate size and number of solar electric
panels to power the pump. The interconnects between the modules and panels
are made with water-tight flex conduit and connectors, utilizing the module
junction boxes. Warranty is limited 10 or 20 years on the PV modules and
limited 1 year on the pump. |
