Residential Solar Installation in Connecticut
iSP Solar designs custom residential solar systems for your home—not a one-size-fits-all package. Before recommending a system, we evaluate your roof orientation, shading, energy use, available installation space, and future energy needs.
Our team oversees your solar installation from the first evaluation to final activation. We handle the site assessment, custom system design, engineering, permitting, utility applications, installation, electrical work, inspections, and Permission to Operate.
Connecticut homeowners go solar for many reasons, from reducing their reliance on utility power to stabilizing long-term energy costs. Solar can also support future electric vehicle charging and pair seamlessly with home battery storage.
Every system should be built to perform reliably in Connecticut’s changing seasons and broader New England weather conditions.

Commercial Solar Solutions for Connecticut Businesses
Commercial solar can help Connecticut businesses, property owners, nonprofits and organizations turn unused roof or ground space into a productive energy asset.
iSP Solar provides commercial solar solutions for offices, retail properties, warehouses, industrial facilities, apartment communities, schools, houses of worship and other commercial properties.
Our commercial solar team evaluates energy consumption, available installation space, property conditions and business objectives before developing a solution. Depending on the property, systems may include rooftop solar, ground-mounted solar, battery storage or commercial EV charging.
We coordinate the technical and administrative details required to move the project from planning to operation while minimizing unnecessary disruption to the property.
Home Battery Storage and Backup Energy
Solar panels generate electricity when sunlight is available. A properly designed home battery system allows homeowners to store energy for use when it is needed.
iSP Solar installs home energy storage as part of new solar projects and can evaluate whether battery storage can be added to an existing system. Battery options may provide backup power during qualifying outages, help homeowners use more of the energy produced by their solar panels and reduce reliance on the electrical grid.
Every property has different backup-power priorities. Some homeowners want to support essential circuits such as refrigeration, lighting and communications. Others want a more comprehensive energy solution. Our team evaluates electrical loads, solar production and household priorities before recommending equipment and system capacity.

Solar System Repair Throughout Connecticut
If your solar system is not producing the energy it should, iSP Solar can help identify the problem and recommend the appropriate repair.
We provide solar repair and troubleshooting for iSP systems and systems installed by other solar companies. Homeowners do not need to be an existing iSP customer to request service.
Common solar problems we investigate include:
- Unexpected increases in electricity bills
- Low or declining solar production
- Inverter faults and error codes
- Solar panels that are not producing
- Monitoring applications that are offline
- Damaged or loose solar wiring
- Failed optimizers or microinverters
- Broken or damaged solar panels
- Roof leaks near solar attachments
- Storm, wind, snow or animal damage
- Communication and connectivity problems
- Shutdowns and electrical safety concerns
Our technicians use system diagnostics and production testing to determine whether the problem involves the panels, inverter, wiring, monitoring equipment, electrical components or another part of the system.

Service for Orphan Solar Systems
Many Connecticut homeowners have solar systems installed by companies that are no longer operating, no longer serving the area or unwilling to provide post-installation support.
These systems are often referred to as orphan solar systems.
iSP Solar services solar energy systems regardless of who originally installed them. Our team can inspect the system, diagnose production problems, troubleshoot inverter and monitoring issues, replace damaged equipment and complete other necessary repairs when possible.
You invested in solar to produce electricity for years. If you no longer know who to call for help, make iSP Solar your first call.

Solar Panel Removal and Reinstallation
Solar panels may need to be temporarily removed when a roof requires replacement, structural work or significant repairs. Removing solar equipment requires qualified professionals who understand both the electrical system and the roofing surface beneath it.
iSP Solar provides solar panel removal and reinstallation throughout Connecticut. We carefully disconnect and remove the equipment, coordinate with the roofing project and reinstall the system after the roof is ready.
After reinstallation, the system is inspected and tested to confirm that its components are connected and operating properly.
Our combined solar and roofing capabilities help simplify coordination and reduce the risk of delays, miscommunication or damage caused by having unrelated contractors handle different parts of the project.

Roofing and Solar-Ready Roof Replacement
Solar panels and roofing should be planned together. Installing solar over a roof that will soon need replacement can result in additional labor and expense later.
Before installing a new solar system, iSP Solar evaluates the roof’s visible condition and suitability for the proposed installation. If roof replacement is recommended, our roofing team can coordinate the work with the solar project.
We provide:
- Residential roof replacement
- Solar-ready roofing
- Roof inspections before solar installation
- Roof penetration evaluations
- Roofing repairs associated with solar arrays
- Solar removal for roof replacement
- Coordinated roofing and solar installation
Working with one company for the roof and solar system creates clearer accountability and a more coordinated installation.

Solar Inspections and Preventive Maintenance
Solar energy systems are designed for long-term operation, but that does not mean performance problems should be ignored. Loose wiring, failed components, animal activity, storm damage, debris and communication errors can reduce production or create additional concerns.
iSP Solar provides inspections and preventive maintenance for residential and commercial solar systems throughout Connecticut.
Our solar maintenance services can include:
- Visual panel and mounting inspections
- Inverter and equipment checks
- Wiring and connection evaluations
- Solar production testing
- Monitoring system troubleshooting
- Roof penetration checks
- Storm damage inspections
- Critter activity inspections
- Panel cleaning when appropriate
- Recommendations for needed repairs
An inspection can be especially helpful when purchasing a home with solar, experiencing unexplained production loss or taking responsibility for a system with limited service records.

Solar Critter Guards and Snow Guards
Birds and squirrels can nest beneath rooftop solar panels, where they may damage wiring, restrict airflow and leave behind nesting material. Solar critter guards create a physical barrier around the array while preserving appropriate ventilation.
iSP Solar installs critter guards designed specifically for rooftop solar systems. We can also inspect the area beneath the panels for visible nesting activity or damage.
Solar snow guards may be recommended for certain roofs to help manage the sudden movement of accumulated snow from smooth solar panels. These systems can provide added protection for entryways, walkways, landscaping and other areas below the roofline.

Flexible Ways to Go Solar
Every Connecticut homeowner has different financial priorities. iSP Solar offers multiple ways to move forward with a solar energy system, subject to property qualifications and program availability.
Available options may include:
Cash Purchase
Purchase the solar energy system directly and retain ownership of the installed equipment.
Solar Loan
Finance the purchase of the solar system through an available lending option while maintaining system ownership.
Power Purchase Agreement
Pay for the electricity produced by the solar system under the terms of the agreement rather than purchasing the equipment upfront.
Solar Lease
Make scheduled payments for the use of the solar equipment while the system remains owned by the third-party provider.
Our solar consultants explain the available options, responsibilities and long-term considerations so you can make an informed decision based on your property and financial goals.

Experience With Connecticut Utilities and Local Permitting
Solar installation requirements can vary by utility territory and municipality. A successful project requires coordination between the solar contractor, local building officials, electrical inspectors and the utility company.
iSP Solar has experience completing projects within both major Connecticut utility territories:
- Eversource
- United Illuminating
Our team also works with municipal permitting and inspection departments throughout the state. We handle the required project documentation and coordinate the steps leading to final system approval and activation.
This Connecticut experience is valuable whether the project involves residential solar, commercial solar, battery storage, roofing or an expansion to an existing energy system.
