There are many variables when it comes to the actual solar installation, but the main components of a typical system include:
OPPD has a Solar Calculator available to help you determine if your home is a good fit and to provide a cost estimate. Solar panels can be installed on most roofs. Here are important factors in determining the cost, size and efficiency of your installation:
There are three major types of solar panels: monocrystalline, polycrystalline (also known as multi-crystalline), and thin-film.
OPPD has a Solar Calculator available to help determine how large of a system you may need based on a number of factors including:
The average residential solar system in OPPD is seven kilowatts (7 kW) which translates to approximately 28 high-efficiency solar panels.
OPPD has a list of Solar/Customer-Owned Generation Trade Allies that are experienced professionals who have been trained by OPPD on the application process, met a list of qualifications, and agreed to standards of conduct. Always get multiple competitive bids before signing a contract.
Here are questions to ask a solar installer, according to the American Solar Energy Society.
OPPD customers who install a qualifying solar system using a Solar/Customer-Owned Generation Trade Ally and whose interconnection application was submitted on or after Jan. 1, 2023 are eligible. See the Terms and Conditions for more information on qualifying systems.
Solar/Customer-Owned Generation Trade Allies can be found at the bottom of our Solar Rebates Program page.
The Trade Ally will apply for the rebate on your behalf. Only customers who use a Solar/Customer-Owned Generation Trade Ally are eligible for the rebate.
OPPD customers with accounts in good standing are up to date on payments on their account and do not have any outstanding debts with OPPD.
The IRS form W-9 is a request for taxpayer identification number and certification used to identify an individual or business for the purpose of fulfilling tax obligations. Rebates issued as part of this program are considered taxable income by the IRS.
OPPD will issue a 1099 form for the taxable year in which you received the rebate. The 1099 form will be mailed by January 31 of the year following receipt of the rebate to the address on file. We recommend you contact your tax advisor with any questions.
Yes, but how much you’ll save and how quickly you’ll be able to offset the cost of your solar system depends on a variety of factors. Hours of daily sunlight, size and angle of your roof, solar panel efficiency, household energy use and your electricity rate all affect your payback period. Check out OPPD’s Solar Calculator for an estimate of how much a solar system might save you. This calculator will also come in handy when comparing contractor quotes for a solar system.
This depends upon a number of factors, such as whether the solar system is owned outright or leased, the age and condition of the roof and solar system, and preferences of prospective purchasers.
You should contact your insurance company to determine if there are any impacts. Some insurance companies may have higher rates or require an additional business policy to cover larger solar systems.
Some homeowners' associations have rules regarding the installation of anything on your property. Consult your covenants for details if you belong to a homeowners' association.
It's not likely. Most landlords will not allow you to place solar panels on their property and it is likely not financially advantageous for you. However, you may still support renewable energy by participating in other renewable programs such as Community Solar or Greener Together Program.
Yes, this process is called net metering. Click here to learn more about net metering with OPPD.
Solar panels require little maintenance, are very durable, and have no moving parts to break down. Any damage that might occur should be covered by your solar system warranty or homeowner’s insurance. Nevertheless, there are some maintenance costs that will arise during the lifespan of your solar panels.
Yes, OPPD has requirements and procedures that must be followed to connect any customer-owned generation to the grid safely and legally. Your system must meet all standards specified in the OPPD Customer-Owned Generation Manual to ensure safe and reliable service, as well as for the safety of field personnel that maintain the electric grid. This process is completed using an online application. Generally, the solar contractor will work through the interconnection process on the customer’s behalf.
The typical wait time for approval to construct is about 3 weeks. The witness test and net meter installation generally take place 1-2 weeks after OPPD has been notified construction is complete and has passed electrical inspection.
Yes, batteries can be installed with solar or as a standalone system. Standalone battery systems are treated like any other form of Customer-Owned Generation and must meet all standards specified in the OPPD Customer-Owned Generation Manual.
A solar system alone will not provide power during an outage. Batteries must be installed along with solar in order to operate during power outages. If you do not have a battery system, your solar system will automatically shut off for the safety of personnel that are working to restore the grid.
A solar system alone will not allow you to disconnect your home from the grid. While off-grid operation is possible, it is very expensive and is usually reserved for remote locations. A backup generator and a large amount of battery storage must be installed along with solar in order to go off-grid.

Your solar system will reduce your electricity usage but it is important to note that electricity usage is only a part of your total bill. There is also a monthly service charge, a fuel and purchased power adjustment charge, and a minimum usage charge during summer months. Click here to learn how to read your Net Meter Bill.
The two electric meters are not measuring the same energy flow. The solar system meter is measuring the total production of your solar system while the OPPD meter is measuring the total amount of energy transferred between your home and the grid. The energy flows from your solar system to your home before it is exported to the grid so the consumption of your home must be subtracted from the solar system’s generation.
There is a minimum charge of $2.07 for customers who use less than 100 kWh during summer billing periods (June 1 – September 30.) Click here to learn how to read your Net Meter Bill.
OPPD’s billing system does not allow for two separate meter reading breakdowns on the same bill. Due to this, only the amount of energy that flowed from the grid to your home and from your home to the grid are shown.

Below are examples of meters showing the location of the meter number.
Typically, an additional meter and meter socket will need to be installed for commercial customers to participate in net metering. The specific details of the installation depends on the type of existing metering as discussed below. In either case, the customer and contractor need to decide where to mount the additional meter socket. Install meters and sockets in accordance with the OPPD Meter Specification Manual.
Expansions of existing systems are treated like new systems. The system must meet all standards specified in the OPPD Customer-Owned Generation Manual and an interconnection application must be submitted. The system must then pass another witness test before it can be operated.
