How to install them correctly comes down to one central idea: this isn’t a weekend project. A solar system touches a home’s roof, its electrical panel, and its connection to the utility grid, all at once. Getting any one of those wrong creates a safety risk or a failed inspection. SunSent Solar and Roofing handles the full installation process for homeowners across Missouri, Illinois, and Kansas, and this guide walks through exactly what that process involves and why each step matters.
Understanding how installation actually works helps homeowners ask better questions, set realistic expectations, and recognize a corner-cutting contractor before signing anything.
Before Installation Begins: What Has to Happen First
A professional solar installation starts well before anyone sets foot on the roof.
A Site Visit and Roof Evaluation
SunSent’s team visits the property to check roof condition, orientation, and shading before designing anything. Skipping this step is one of the most common reasons a system underperforms once it’s live.
Reviewing the Home’s Electrical System
The home’s existing electrical panel has to handle the new solar connection safely. SunSent evaluates this during the same visit, since an outdated panel sometimes needs an upgrade before installation can proceed.
Designing the System Around Actual Energy Use
Installers size a system based on a household’s real electricity usage, not a generic estimate. SunSent reviews utility bills directly so the finished system matches what the home actually needs.
Permits and Approvals Before Any Panel Goes Up
Installing solar panels legally requires sign-off from more than one authority, and this stage protects both the homeowner and the installer.
Pulling the Correct Local Permits
Each city and county across Missouri, Illinois, and Kansas sets its own permitting requirements for solar work. SunSent handles this paperwork directly, which keeps projects from stalling over a missed form or an unfamiliar local process.
Getting Utility Interconnection Approval
Before a system can connect to the grid, the local utility has to approve the interconnection. SunSent’s established relationships with regional utilities help this step move without unnecessary delay.
Installation Day: How Panels Actually Go On the Roof
Once permits are clear, the physical installation can begin, and this is the part most homeowners picture when they think about how solar panels get installed.
Mounting the Racking System
Installers attach a racking system to the roof structure first, using mounting points designed to avoid compromising the roof’s waterproofing. SunSent uses hardware suited to the home’s specific roofing material, whether that’s asphalt shingle or another surface.
Wiring and Electrical Connections
Licensed electricians handle the wiring between panels, inverters, and the home’s electrical panel. This is not a step for an unlicensed installer to attempt, since improper wiring creates a genuine fire and shock hazard.
Panel Placement and Securing
Panels get mounted onto the racking system, wired together, and secured against wind uplift. SunSent’s crews follow manufacturer specifications closely here, since improper mounting voids most panel warranties.
After Installation: Inspection and Activation
The system isn’t finished the moment the last panel goes up. A few more steps remain before it can actually produce electricity.
Final Inspection by a Local Authority
A local building or electrical inspector reviews the completed installation against code before approving it. SunSent prepares thoroughly for this step throughout the project so the inspection goes smoothly the first time.
Utility Activation (Permission to Operate)
Even after passing inspection, the utility company still has to grant final permission before the system can go live. SunSent coordinates this step directly with the utility so homeowners aren’t left waiting without a clear timeline.
System Monitoring Setup
SunSent sets up production monitoring so homeowners can track how much electricity their system generates. This final step turns installation into something homeowners can actually understand and verify over time.
Why DIY Solar Installation Isn’t a Realistic Option
Some homeowners search for how to install solar panels themselves, hoping to save on labor cost. The reality works against that plan in a few important ways.
Safety Risks of Amateur Electrical Work
Connecting solar equipment to a home’s electrical system incorrectly creates real fire and electrocution risks. This work genuinely requires licensed electricians, not just careful research.
Permit and Inspection Barriers
Most municipalities require a licensed contractor to pull solar permits, which effectively blocks a true DIY approach from the start. SunSent’s licensing and local relationships clear this barrier automatically.
Warranty and Insurance Complications
Self-installed systems often void manufacturer warranties and can complicate homeowners insurance coverage. Professional installation through a company like SunSent keeps both protections intact.
Solar Installation Services Across Missouri, Illinois & Kansas
SunSent installs solar systems for homeowners throughout the St. Louis and Springfield areas of Missouri, the Kansas City metro along the Missouri-Kansas border, and communities across central Illinois.
Local installation experience speeds up nearly every step described above, from permitting to utility approval. A company unfamiliar with a specific city’s requirements can lose real time figuring out who to call, while SunSent’s regional familiarity keeps projects moving.
Training and Certification Behind a Safe Installation
The North American Board of Certified Energy Practitioners sets industry-recognized standards for solar installer training and competency (NABCEP, Certification Standards). The U.S. Department of Energy also outlines the general installation process and safety considerations homeowners should expect from any qualified installer (Energy.gov, Solar Installation Basics). SunSent’s installation standards align with this guidance throughout every project.
What Homeowners Say About SunSent’s Solar Installation Work
“We have been very satisfied with our solar panels and SunSent’s customer support team. They have been quick to respond to any questions we have had and have been very professional throughout the entire process.” — tmmeyer22, Google review
That kind of responsiveness matters most during installation week, when homeowners want clear answers about what’s happening on their roof and when.
Frequently Asked Questions About Installing Solar Panels
Can a homeowner install solar panels themselves? Technically possible in a few jurisdictions, but most areas require licensed professionals for the electrical work and permitting. SunSent handles the entire process safely and legally from start to finish.
How long does the full installation process take? From site visit to activation, most residential projects take a few months, largely due to permitting and utility approval timelines rather than the physical installation itself. SunSent provides a project-specific timeline upfront.
What happens if the roof isn’t ready for solar panels? SunSent identifies roof issues during the initial site visit and addresses repair or replacement needs before installation, since this division handles both services under one team.
Does installing solar panels require an electrical panel upgrade? Sometimes. SunSent evaluates the home’s existing electrical panel during the site visit and flags any upgrade needs before finalizing the project cost.
