What makes CutMyBill better than other solar cost and savings calculators for Duke FL customers?

There are three key reasons that our Duke FL solar cost and bill savings calculator is far better than any other solar calculator or solar estimate website on the net for Duke FL customers;

  • Firstly, whilst most solar panels calculators are really good at forecasting the electricity production you can get from installing solar panels for your home (because they all rely on the pwatts.nrel.gov solar production data) most of them just use a single generic state wide unit cost for electricity in their calculations. Our Duke FL solar cost and bill savings calculator actually uses our database of each of the available Duke FL electric rates plans to use more specific electricity cost data. Therefore we can generate much more accurate solar savings analysis.
  • The second reason is that we use DOE (Department of Energy) electricity usage patterns for the Duke FL service territory, and some very basic questions we ask you about your home to estimate how you use power over the course of a day and the seasons of the year. This allows us to accurately forecast solar savings where time of use electricity plans are available to you. We estimate your electricity usage for each hour of the year and then overlay the known production of solar panels in your area for each hour of the year. Without this level of detail solar panel cost and savings calculators on are inaccurate; and
  • Lastly, before we even consider solar savings, we look for any savings that can be achieved simply by swapping to a cheaper available Duke FL rate plan. Our software looks for any available Duke FL rates plan that works our cheaper for your estimated usage pattern. Generally speaking savings from swapping to a cheaper Duke FL rates plan are only available to those who have larger monthly electric bills but given it only takes a phone call to achieve these savings it is by far the quickest and easiest bill cutting option where it is possible.

Will installing a solar power system or swapping rate plans save me the most on my monthly Duke FL payment?

There are almost always far greater cost savings to be obtained from installing solar panels than swapping rates plans but this doesn't mean possible savings from swapping rate plans should be ignored. The other reason we search for your cheapest rate plan is that to forecast total possible savings you could get on your bill you need to take into account both savings that may be available from swapping to the cheapest rate plan and also savings that come from swapping your generation source for some of your power usage to your own solar power.

How accurate is the CutMyBill estimate of my power usage pattern?

The CutMyBill electricity usage profile estimator is a key part of the technology of why CutMyBill can forecast solar and bill swapping savings so accurately without requiring you to enter your kilowatt hour electricity usage for each month of the year or to upload 12 months worth of power bills.

The way we do this is we use electricity use profiles collected by the Department of Energy for each building type at each weather station across the Duke FL service territory. Some of the characteristics of your home such as your average monthly power spend and the square footage of your home are used to refine this analysis.

This gives a fairly accurate estimate but it is not an exact estimate. The best way to get an exact estimate of your solar savings and whether or not there are possible savings from swapping rate plans is to speak to one of your local solar companies. Whilst solar companies are experts in solar they also become experts in knowing the cheapest rate plans (both before and after solar) from their local utility companies.

Three best ways to cut your Duke FL bill

Did you know you can cut your home's electric bill by using flashlights instead of overhead lights? Did you know you can cut your home's electric bill by doing an energy inspection each hour?

Yes, those are silly questions. Fortunately, you don't need to sacrifice comfort to cut your electric bill by 10% or more. And it could be very easy to do.

This article is specific to Duke Energy's Florida coverage. We hope it helps you make a solid game plan to cut your Duke FL bill. If you haven't already, consider first reading our explanation of how your electric bill works.

Introducing the Jones family

To illustrate ideas, we'll show numbers based on typical energy use for a single-family home in Orlando.

Meet our typical family from Orlando: the Jones family. If you look closely at their picture, you'll see that the dad is also reading this article. The mom and daughter are saving energy by just pretending their tablets are on.


In this article, we'll see how the Jones family cuts their monthly energy bill by 8% ($14).

Is it worth using less energy?

We won't rally behind former President Jimmy Carter and tell you to put on a sweater and turn down the thermostat. We'd rather not see our breath in the living room. But it's probably worth taking 5 minutes to consider whether energy is wasted in your home (in other words, is energy used that does not improve well-being).

The Jones family children have been politely asked to turn off lights when leaving rooms about 17 trillion times. They're generally respectful, but for whatever reason this one doesn't stick. How much money would the Jones family save if the children always turned off their lights?

Three 30-watt lights get left on in empty rooms 2 hours per day on average. That's 5.5 kilowatt hours per month which costs $0.69. Is it worth continuing the effort? Nope. The parents will let this one go for now.

What about energy efficiency?

There might be one or more basic energy-efficiency investments you can make that'd cut your electric bill while not reducing comfort or adding day-to-day complexity.

The Jones family got a new refrigerator a decade ago, and plugged in their previous 1990s-era fridge in the garage (for those three sports drinks). Refrigerator efficiency has come a long way since the 1990s. In fact, their garage fridge uses over twice as much energy as their new Energy Star fridge. It costs them $10.76 per month to run it.

Should they replace the old garage fridge with a basic $500 Energy Star fridge? They'd save $6.19 per month on their Duke FL bill, but the related financing payment would be $9.44 per month ($500 borrowed, 5-year term, 5% interest). Their net loss in the first month would be $3.25. With the financing cost, the new fridge would pay for itself in 7.6 years (followed by years or decades of pure bill savings).

The Jones family decided they don't actually need a second fridge. That's a $6.19 per month bill reduction!

The Jones family's game plan so far

The Jones family has felt the pain of high electric bills for years. Thanks to this article (we have no shame), they're now ready to take control and cut it. Sounds like fun!

Their current average monthly bill is $175. Here's their game plan:

Reduce Energy Waste Unplug the garage fridge (and schedule a recycling-center pick up time).
When This week.
Bill Reduction $6.19
New Monthly Bill $169

One week later the Jones family's new monthly bill is $169. They cut their bill by 4%.

They're happy that they were able to cut their bill, and in their enthusiasm they're wondering if they can cut it even more. That's when little Suzy got a bright idea. "Hey Mom and Dad, what about solar energy"?

Yeah Suzy, What about solar energy?

"Hmm...it's probably too expensive". The Jones family wanted to at least consider it, so they got in touch with a few local solar installation companies through Solar-Estimate.org. They were happy to hear that solar energy is affordable, it's only half the cost it was just 8 years ago.

They learned that 20 solar panels would fit nicely on the sunniest part of their roof (that's a 4.8 kW system). That'd bring their net monthly energy use from 1,397 kWh down to 734 kWh, and would get their monthly Duke FL energy bill down to only $92.

They learned they could finance the solar system through a solar-loan provider, and that their bill savings would be higher than the financing cost. In other words, there'd be no down payment and they'd start saving money immediately. Their $92 electric bill plus a $68 monthly financing payment would put them at a $161 per month energy cost. So their solar energy system would cut their monthly energy cost by 5%, or $8. A local solar professional would be happy to talk you through the math.

The Jones family went solar.

Jones family conclusion

If they took no action, the Jones family would be paying $175 per month for energy. Unplugging the garage fridge got their bill down to $169. With solar energy and the solar financing payment, the Jones family's new net energy cost is $161. All together, they cut their monthly energy cost by 8%, or $14.28. The Jones family is feeling good! Here they are monitoring their real-time solar production and utility energy use.

Family monitoring energy usage

Energy bill reductions = tax-free income

That $14.28 of extra cash is actually worth $20. What? The Jones family has to pay income tax on money used for personal expenses (including their electric bill). Since they no longer need to pay $6.12 in taxes on the $14.28 they're not giving Duke FL, the net electric-bill reduction is worth an extra $6.12. The big take home here is that electric bill savings is more valuable than a conventional investment's return.
