What To Expect During The Solar Panel Installation Process

Delta Energy Solar helps homeowners in Oklahoma City and surrounding areas. The solar panel installation process may be slightly different if you are in a different state. 

It’s normal to be intimidated by the solar panel installation process! Many homeowners are hesitant to make the switch because of the permit process, agreements, and other steps needed before installing solar panels.

Overall, the solar panel installation process takes 1-3 months to complete. Most of that time is getting the city permits and approval from your utility company. The good news is that our dedicated Account Managers handle this entire process for you!

To create transparency throughout the process, we created this online guide for homeowners to know what to expect and the average timelines for each step in the solar panel installation process.

Solar Panel Permitting & Approval

Once you’ve met with our team and had your home inspected, our experts will design a home energy system to meet your needs. Once that is completed, and an installment agreement is signed, our team will begin obtaining the solar permits. There are several organizations involved, including:

  • City permitting department

  • City engineer 

  • HOA 

  • Utility company

  • Financing company and/or bank

In total, obtaining solar panel permits and approval can take 2-6 weeks. Due to each department operating on its own timeline, it’s often hard to gauge exactly how long the process will take. We aim to stay organized and on top of this process, so you don’t have the added stress of submitting documents and working with multiple organizations!

Interconnection Agreement

If you choose to remain connected to the energy grid, your utility company will require what is known as an interconnection agreement. This is also known as net metering. The application includes your home’s energy usage, solar panel size and specifications, and engineering design. In some cases, there is a fee associated with the application, but we’ve got it covered.

Solar Panel Installation 

Once all permits are received, and materials are ordered, our experienced team steps in to complete the solar panel installation. The overall process takes about 1-2 days to complete. 


The solar panel installation process can vary between homes. For example, older homes may need electrical boxes or wiring updates to meet local building codes. We will work with you to outline all steps, so you know exactly what happens on installation day.

Final Inspection

Once the solar panels are installed, expect one more round of inspections. These are required to ensure your solar energy system meets safety regulations and electrical, building, and fire codes. Some areas may require the assessment to happen during the installation. Other areas may require a final inspection before you power on your system. Either way, our team will work to ensure everything is ready and coordinated for the final inspections to occur. 

What Happens If The Solar System Doesn’t Pass Final Inspection?

Personally, this has never happened to us. Based on what we know, if the solar panels are not installed correctly, the project will likely be rejected during the final inspection. This is one of the many reasons choosing a local solar company is so important! You’ll want to ensure the team completing the solar panel installation is knowledgeable and has years of experience. It’s not uncommon for national solar companies to use unskilled or under-trained laborers, leading to later problems.

Solar Panel Permission To Operate

Once the solar panel installation process is complete, and the system has passed the final inspection, we will apply for “permission to operate” from your utility company. Some projects may require a two-way energy meter that tracks the energy you produce and the energy you use to obtain the net-metering credits.

Activation 

Turning on and activating your solar panels is easy and only takes a few minutes. First, turn on the “PV Solar Breaker” switch in your electric panel, turn on the AC disconnect, and turn on the solar inverter. Our team will be there to help!

Solar Panel Monitoring 

After the solar panel installation process is complete, your home will be generating clean and efficient energy from the sun! After your system is active, there are still a few things you can do to make sure you get the most out of your solar panels:

  • Track the performance of your solar panels using our app. This will help you understand peak hours and when your solar panels are making the most power. 

  • Monitor home energy consumption. Increasing energy consumption could mean you will see changes in your electric bill. An example of this would be buying an electric vehicle. Should you need to increase electricity production, you can add additional panels later.

  • Take care of your solar panels. Know how to perform solar panel maintenance and when to do it. This will increase the lifespan of your system. Access our free guide on what to expect here.
