New to this form, Need Variable Speed Motor Conversion advise Please

[Ranch]

Looking to see how much I will save per summer months and winter months. ABOUT
Based on the following.
We currently have about a 20k gal Screened in pool -deep end 6ft.
1.5 inch piping.
1.5 Hp single speed motor, working good now
RP 3450, VOLTS 230/115, AMPS. 8.5/17.0
Hayward DE Filter, clean as needed. (Large?)
Solar pool panels not used often. Only spring and fall for maybe 4 hrs a day.
Hayward pool cleaner. 1-2 x a week.
Our pool is usually very clean. We test it often in the summer.
Chlorine tablets currently, would like to go salt system in a year.
In the winter we run it about 5 hrs and it is clear
Summer run 8 hrs.
Thinking of purchasing a Pentair SuperFlo High proformance V Speed 350097, was told about it is about a 1.65 hp
Elect kwh is 16 cents, if I figured it correctly
(Total use is 1617 kwh Bil is $263.00 for just usage. Other month fees additional )
We have 240 volt and 120 available on site.
Plan to purchase a flow meter, when new pump installed.
From reading online looks like I need to schedule about (in summer)
2 hrs. 3,000 speed, cleaner or solar panels (or possibly salt chlorinator included?)
2-4 hrs 1500-1750. Salt chlorinator
18-20 hrs on low 500
All pools are different so I may need to adjust times and speed. Looking realistic at this.
Any idea on the Savings per year?
How long the motor will last approx?
Thanks- Retired so watching our budget.

Welcome!

You really can't go too big with a variable speed pump. Think of them as variable HP. By increasing or decreasing speed, you can accommodate any plumbing configuration. The goal is to run the pump at as low as speed as necessary. Doubling pump speed generally requires 7 to 8 times the energy. I doubt you'll get much done at 500 RPM on a 20K gallon pool. Most folks that run pumps at low speed start at abut 1,000-1,200 RPM.

Here's a chart typical of a 3HP variable speed pump that may help you determine cost/savings...

There's nothing wrong with the SuperFlo series of pumps. If you're not tied to an automation system, many have found this pump to be a very good value:

What pump do you have now? How is it controlled?

Here is a cool site somebody shared here to calculate energy cost.

Energy cost calculator

Electrical energy cost calculator and how to calculate.

I switched a few years back and it was noticeable for sure.
Another benefit is VS pumps are a lot quieter.
