FAQ's and Facts
How much electricity is your pool pump using?
A basic electrical calculation using “Ohm’s Law” requires obtaining the voltage and amperage of a device. Ohm’s law states that if you know the volts and amps of a device, you can then calculate the Watts. Located on the pool motor is the rating plate. Note that there will be two units of information required: 1) the voltage and 2) the amperage (see example below).
Often times the motor will state two voltages and likewise two amperages. In regards to the calculation sheet prepared for the Homeowner, this will have no effect on the outcome of the calculation. However, it is noteworthy that the voltage will typically be stated as 115/230 and the amps will likewise state two amperages. In the example below, the amperages are 18.6/9.3. When the motor is wired for 115 volts the higher or first number is used, and when wired for 230 volts, the lower amperage will be used. Most pool systems are wired to run on 230 volts. Below is an example of a 1.5 horsepower motor specification and the calculation to show how to determine the kilowatt-hour consumption.
What does it cost for your pool pump to operate?
Example:
- Pool motor volts X amps = Watts .....................230 v X 9.3 a =2139 Watts
- Divide by 1000 = kWh .....................................2139 W / 1000 =2.139 kWh
- Multiply by hours of day (run time) ..................2.139 X 8 hours = 17.11 kWh daily
- Multiply by number days in billing cycle............17.11 X 30.4 days= 520.20 kWh per month
- Multiply by cost of KWH = monthly savings.......520.20 X R1.10 = R572.23 Monthly Savings
- Multiply monthly savings by 12 = Annual Savings....R572.23 X 12 = R6,866.70 Per Year
How to calculate your pool pump electrical consumption:
_________ X _______ = _______Watts
(Volts)..........X.. (Amps)
_________ / 1000 = __________kW
(Watts)
_________ X ___________ = __________kWh/Day
(kW)............X...... (Hrs/Day)
_________ X 30.4 days = _________ kWh/Month
(kWh/day)
____________ X R1.10 = $_________ Monthly Cost
(Monthly kWh)
R____________ X 12 = $_________ Annual Cost
(Monthly Cost)
What size solar pool pump should you get?
Proper filtration of the pool requires the water to pass thru the filter at least once per day; this is also referred to as “turning the water over”. Current Automation offers two solar powered pool pump systems, thereby allowing us to filter from the smallest of pools up to 36,000 gallons with a single system. Pump systems can be plumbed together to filter even larger pools.
Current Automation Systems are not sized by kilowatt, rather volume of water to filter. One of the many great aspects of the system is that
all systems utilize the same pump, motor and controller assembly. The more energy delivered to the controller the higher the revolutions and the greater the flow rate. The two systems are based on the amount of Watts delivered to the Motor Controller. However, depending on the pairing of the solar panels, the total Watts being delivered to the system is the actual size.
What is your annual return on investment (ROI)?
On average, the annual return on investment is 30% - 38 %.
Which means you could pay off your investment within 3~4 years from installation date, just on your electricity bill saving.
(Assuming Eskom cost is R1.10 / kWh and does not have an increase within 3 years, which means if they do, you'll pay it off quicker!)
