Adding solar panels and switching rate plans can lower your Duke Energy Indiana electric bill
Updated: October 22, 2020There are three ways you can reduce your Duke bill: changing your habits, switching your rate plan, and adding solar panels.
You've probably heard a lot about reducing energy consumption by doing things like switching to LED lightbulbs and adding insulation to your walls, but these fixes are relatively easy compared to the far more impactful step of making changes to your lifestyle.
The second thing you can do is switch your rate plan. Duke doesn't offer time-of-use billing that can help you save money by shifting your usage of energy-intensive appliances to off-peak hours, but there may be other options for you .
Finally, you can reduce or even eliminate your electricity bill by installing solar panels on your home.

How much can I reduce my Duke Energy Indiana bill by switching to a different rate plan
For some people, the savings from switching rate plans may only be a few dollars per month, but for many it can be $20-$100 per month. That's between $240 and $1,200 that you may now be paying to Duke Energy Indiana each year for no reason.
Finding out what's available to you is as simple as a phone call or email to Duke Energy Indiana. Even a small savings can be worth it.
Are solar panels worth it for Duke Energy Indiana customers?
Probably. With solar property tax exemptions available, and Duke Energy’s strong net metering policy, solar panels can be a pretty smart investment in Indiana. Duke’s excess solar generation rate rider also allows you to at least get full credit on your power bill for the excess solar electricity your panels produce which you can’t use onsite. Your credits accrue at the same rate you pay for electricity, and roll over to the next month’s bill.
Does Duke Energy Indiana offer full 1 for 1 net metering credits for exported solar power
Yes, Duke Energy Florida offers 1 for 1 net metering. This means you are paid the same rate for excess solar energy that you export to the utility grid during the middle of the day as what you pay for power purchased from the grid. These net metering rates are offered at retail rates as long as the total solar energy sent to Duke is at or below 1.5% of their peak loads.
In the case of Duke Energy Florida, this is approximately $.12 per kWh.
What incentives, tax credits and rebates are available to Duke customers for installing solar?
The major financial incentive currently available until the end of 2023 is the 30% federal solar tax credit. The way this works is that the full cost of the system needs to be paid to the installer, and this tax credit can then be claimed back as cash when you next do your taxes.
Many states, local governments and utilities also offer incentives for homeowners who go solar. This help can take the form of state tax credits, rebates, tax breaks, SRECs or even performance-based incentives. The best part is that all of these incentives apply in addition to the federal credit.
Here is every incentive you may be eligible for as a Duke customer:
