*Solar panel cost varies by location, solar panel mqanufacturer, system size and the amount of electricity your home uses.
There are three ways you can reduce your CMPC 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. CMPC offers time-of-use billing that can help you save money by shifting your usage of energy-intensive appliances to off-peak hours, and there may be other options for you as well.
Finally, you can reduce or even eliminate your electricity bill by installing solar panels on your home.
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 Central Maine Power each year for no reason.
Finding out what's available to you is as simple as a phone call or email to Central Maine Power. Even a small savings can be worth it.
Probably. With the 26% Federal solar tax credit, home solar panels are an investment worthy of your careful consideration as a Central Maine Power customer. Maine’s net metering policy also ensures you get credited on your power bill at full retail rates for the excess solar electricity your panels produce. Your credits are rolled over and applied to your next month’s Central Maine Power bill.
Yes, Central Maine Power 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.
In the case of Central Maine Power, Time of Use (TOU) pricing applies. You will earn an average of $0.12 for power exported at peak rate times, and an average of $0.06 for power exported at off-peak times.
The major financial incentive currently available until the end of 2021 is the 26% 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 CMPC customer:
*Based on 8.90 kW system, average installation cost $24,261
If you input the details for a CMPC customer with a power bill of $150 per month into the best online solar panels calculator, it tells you that you need a 8.90 kW solar system that will produce 12,001 kWh per year and that this system will return the owner a $37,325 profit after repaying the cost of the system.
The solar savings possible for you as a CMPC customer will depend on the amount of electricity you use and the cost of the solar system you buy. Savings also vary based on the direction of your roof or any shading of your roof that affects output.
Here is a monthly and lifetime solar savings estimate for the same relatively typical CMPC customer with a $150 per month electric bill prior to solar and who installs a 8.90 kW solar system.

While most homeowners decide to install solar panels because of financial savings over time, the environmental impacts of this choice are the primary motive for others. Here is a breakdown of the environmental benefits from a Central Maine Power customer installing a 8.9 kW solar system on their property:A solar system generating 12,001 kWh per year will save you money AND make the world a nicer place
The cost of installing solar panels will vary with brands of solar panels and inverters you choose and also the installation company you choose to install them.
It is common to see really good systems, using quality brands of equipment, being sold for around $2.73 per watt or $17,955 for a standard 8.90 kW solar system after the customer claims the 26% federal solar tax credit.
While Duke Energy’s new net metering program will cut customers’ solar savings, it could potentially increase battery installations.
Some solar installers use inflated estimates of utility price growth to make it seem like savings will be higher than they likely will. It’s time to stop.
