Start By Choosing a Reputable Solar Installer

It’s so important that you choose the right solar installer if you’re going solar. Not only do you want to choose an experienced solar installation company, but it’s also a good idea to stay local. Local solar installers understand your weather, know the ins and outs of state rebate and discount programs, and are much more likely to provide a better customer service experience in comparison to national vendors. 

Maybe most importantly, a local installer will be less expensive than a national company. According to a study by the National Renewable Energy Laboratory (NREL), a local solar installer could save you 10% on installation costs for your home solar system. 

How Experts Install Solar Panels: The Process

Before we get into our specific installation process, it’s a good idea to take a look at the overall process of how to install solar panels. This general overview will help you understand the most common requirements that are needed for a professional solar installation. 

Sign Your Contract

This first step will help you understand exactly what’s to come in your installation process. Your contract is a detailed explanation that should be used as a guide if you ever have any questions about your particular system. Most importantly, the contract will also show you the details related to how you choose to finance your solar power investment. Within your contract you will also choose your equipment, such as your solar panels and inverters. 

Evaluation of Your Home/Office Building

An engineer is needed to evaluate what kind of electrical system you currently have in place to make sure your new system is compatible. Two important components that your engineer will evaluate are the type of electrical box that you currently have in place and the status of your roof. For obvious reasons, you never want to install solar panels on an old, failing roof.

Start the Paperwork Process

Paperwork for permits, inspections, rebates and incentives are all a part of the early process. This can be a lengthy step in the process because the paperwork has to flow through many channels to receive different types of approvals. However, it’s also an essential step to make sure you are legally operating with all safety measures accounted for in your plans.  

Roof Preparation

If your roof is old and damaged, it’s possible that you might need a complete roof replacement before you can install solar panels. In cases of minor damage, your installer might make a few quick fixes to any shingles that are loose or broken. Once your roof is ready to go, the electrical wiring is installed so that your panels can be connected. 

The Installation of the Panels

This is the part where everything comes together. The panels will sit on a racking that is leveled and spaced out properly across your roof. Finally, your inverters are connected to your paneling. 

Final Inspections

The final round of inspections will come from two sources: your local town government and a representative from the electrical company. Both inspectors will check for quality and safety related to the installation process. Once you are given the “OK” by both inspectors, your electrical company will connect your solar system to the grid. At this point, your installation process is complete.
