Illinois's Premier Home Solar Company
What to Expect
When you purchase a solar system with Certasun, you are partnering with an expert. We work diligently to design and install a safe, attractive, and efficient system. Once you accept our proposal, here’s what you can expect:
1. Site Survey
Our first step is a detailed site survey, which we can usually do within just a few days. We will schedule a time to come to your house so we can take pictures and gather information vital to the system engineering and installation process. Our team will measure your roof, record its slope, and verify the location of obstructions that we saw when doing the initial design. We will also gather information on your electrical service and main distribution panel. If we find any significant deviations from what we assumed in our proposal, we will notify you right away.
2. System Engineering
With the information gathered at the site survey, we create detailed construction drawings. We will use them to get the required permits and, if necessary, get approval from your homeowners association.
3. Building Permits
Once the system is engineered, we apply for any building permits required by your municipality. Every municipality has different requirements, so our expert team will put together a custom package to receive approval as quickly as possible. Depending on where you live, this could take as long as three weeks.
4. Utility Interconnection
When we apply for your building permits, we also apply for permission to interconnect your system to your utility and for you to receive credit for any energy you send back to the grid (known as “net metering“). Most utilities take around four weeks to approve these applications.
5. Illinois Solar Incentive
After we apply for permits and interconnection, we will file with the Illinois Power Agency to secure your state incentives. This ensures your money is available to you as soon as possible.
6. Installation on Your Home
When all the above steps are complete, we are ready to install your system. We will coordinate with you to schedule installation on a day that is convenient for you. Home solar installation takes one to three days, depending on the size of your system and the complexity of the project. We install your system using a three-step process. First, we prepare the roof and lay down the rails that will hold your panels. Next, we firmly fasten the panels to the rails. Finally, we complete the wiring and add a monitoring device that will allow you to see your system’s performance on the internet.
7. Inspections and Approvals
Once we complete your home solar installation, we arrange for an inspection by your municipal inspector. In some cases, we may need an additional approval from your utility. Once we have these approvals, we are ready to turn on your system.
As soon as we turn on your system, you will start saving money and producing 100% renewable energy. For most homes, this is 60-90 days after you accept our proposal. Before we leave, we introduce you to your system, show you how you can monitor its performance, and answer any questions you have.
