Is Your Solar System Underperforming?
You invested in solar to produce electricity, manage energy costs, and rely less on the utility company. If your system isn’t performing as expected, you need a solar service company that can identify the issue and fix it.
It doesn’t matter who installed your solar system.
If your solar panels, inverter, monitoring equipment, battery, wiring, or other components aren’t working properly, call iSP Solar. We’ll diagnose the issue and provide the service, maintenance, or repairs you need to get your system performing at its best.
If your system isn’t operating at full potential, iSP Solar is who to call!
Your Solar System Should Be Saving You Money
A solar energy system doesn’t always shut down when something goes wrong. Often, it keeps running but generates far less electricity than it should.
That drop in output can go unnoticed for weeks or even months—especially if you don’t check your monitoring data regularly or compare current production to past years.
Reduced solar production can result from:
- A failing inverter or microinverter
- One or more underperforming solar panels
- Loose, damaged, or corroded wiring
- Communication or monitoring failures
- Shading from new tree growth
- Dirt, pollen, leaves, snow, or other debris
- Animal damage beneath the solar array
- Roof, flashing, or mounting problems
- Storm, wind, snow, ice, or hail damage
- Aging or discontinued equipment
- Improper system configuration
- Electrical faults or tripped breakers
- Battery storage or communication issues
- A system that was never commissioned correctly
- Previous repairs or roof work that affected the system
If your electric bills are climbing or your solar output has dropped, don’t assume your system is simply aging. A professional solar inspection can pinpoint the issue and determine whether a repair, replacement, adjustment, or routine maintenance can restore lost production.
iSP Solar is Your Solar Repair Company
iSP Solar Offers Complete Solar System Repair Services
iSP Solar provides complete solar service for residential and commercial systems, helping you keep performance high while reducing downtime and lost energy production. Every visit starts with a full system inspection of your entire setup—panels, inverters, wiring, connections, monitoring tools, and overall system condition—not just the first part that shows an error. This end-to-end approach helps our technicians find the real cause faster, prevent repeat problems, and recommend the right repairs or adjustments with confidence. The result: quicker diagnostics, reliable fixes, and a system that performs efficiently for years to come.
Solar System Diagnostics and Troubleshooting
Solar diagnostics are the first step to an effective repair. Our technicians identify the root cause of low energy output, unexpected shutdowns, fault alerts, communication issues, and other system problems.
Depending on the system and reported issue, diagnostics may include:
- Reviewing available system production data
- Checking inverter or microinverter fault codes
- Evaluating individual panel or circuit production
- Inspecting electrical connections and components
- Testing system voltage and performance
- Checking breakers, disconnects, and combiner equipment
- Evaluating monitoring and communication devices
- Inspecting panels, racking, wiring, and roof penetrations
- Comparing current production with expected performance
- Identifying damage, deterioration, shading, or obstructions
- Determining whether equipment should be repaired or replaced
Once the problem is identified, iSP Solar will clearly explain what the team found, walk you through the key details, and answer any questions you may have. From there, we’ll recommend an appropriate, practical path forward tailored to your system and goals.
Call To Schedule Your Solar System Repair
Solar Inverter Repair and Replacement
The inverter is one of the most important parts of any solar energy system. It connects your solar panels to the electricity you use every day by converting the panels’ direct current (DC) into alternating current (AC) for your home or business. Because it controls this conversion, the inverter plays a major role in overall system performance. If it fails, energy production can drop, the system may display error messages, or the entire system may shut down until the problem is fixed.
Common signs of an inverter problem include:
- Inverter error codes or warning lights
- No solar production
- Intermittent system shutdowns
- A monitoring app showing missing production
- One section of the system not producing
- Unusual noises from the inverter
- Repeated breaker trips
- Production that is significantly below expectations
iSP Solar can quickly diagnose issues with both inverters and microinverters, pinpoint the root cause, and identify any failed or underperforming components. From there, we perform applicable repairs whenever the problem can be resolved safely and cost-effectively, and we’ll recommend a full replacement if repair isn’t practical or would be unreliable long term. When appropriate, we can also help you determine whether your existing equipment may be covered under a manufacturer’s warranty, and guide you through the next steps.
Solar Panel Repair and Replacement
Solar panels are designed to withstand years of sun, wind, rain, and shifting temperatures, delivering steady performance in harsh outdoor conditions. However, impacts, debris, wiring issues, or normal wear can damage panels, reduce efficiency, and cause a noticeable drop in output over time.
Panel problems may be caused by:
- Cracked or broken glass
- Storm, wind, hail, snow, or ice damage
- Fallen branches
- Hot spots or internal cell damage
- Loose electrical connectors
- Moisture intrusion
- Animal activity
- Manufacturing defects
- Aging or degraded components
- Improper installation
- Roof or construction work around the array
Our team will thoroughly inspect the affected panel, surrounding equipment, and connected system components to identify the safest and most reliable next step. We’ll confirm whether the panel can stay in service with confidence or if replacement is the better choice. If an exact replacement isn’t available due to age, model updates, or discontinued parts, we’ll review compatible alternatives and clearly explain your options. We’ll also show how any replacement may affect the rest of the system, including fit, performance, code compliance, and long-term maintainability.
Signs Your Solar System Needs Service
Contact iSP Solar if you notice any of the following:
- Your electric bill is higher than expected
- Solar production has dropped significantly
- Your system is producing no electricity
- The inverter displays a warning light or fault code
- Your monitoring app stopped reporting
- One or more panels appear inactive
- Your system repeatedly shuts down

- Your system has never produced what you were promised
Even without visible physical damage, a clear drop in performance can be an important warning sign. It may indicate a failing component, incorrect configuration or software settings, a communication or connectivity issue, or an electrical problem that disrupts normal operation.
Solar Monitoring System and App Troubleshooting
Your monitoring system is essential for confirming that your solar investment delivers the savings and performance you expect. If the monitoring platform, gateway, internet connection, or other communication equipment stops reporting, your array may still be generating power—but you lose reliable insight into how it’s performing. Without steady data and timely alerts, problems can go unnoticed, production losses can add up, and it becomes harder to confirm output, diagnose issues, and ensure your system is operating at its best.
iSP Solar can troubleshoot:
- Solar monitoring apps that stopped updating
- Missing production data
- Lost Wi-Fi or internet connections
- Gateway and communication failures
- Incorrect system information
- Panels or microinverters missing from the monitoring portal
- Monitoring accounts that were never transferred
- Systems connected to a previous homeowner’s account
- Alerts, fault notifications, and communication errors
We help you reconnect compatible systems quickly and safely, restore the reporting you depend on, and return dashboards and alerts to a reliable state. We also determine whether the monitoring issue is a simple configuration gap or a sign of a deeper production problem that needs attention.
Solar Wiring and Electrical Repair
Damaged wiring and faulty electrical connections can disrupt production, cause unplanned downtime, and drive up maintenance costs. They also pose serious safety risks, including electrical shock, equipment damage, and fire.
Our solar electrical troubleshooting services can address issues involving:
- Loose or damaged wiring
- Corroded electrical connections
- Broken or disconnected connectors
- Damaged conduit
- Grounding and bonding concerns
- Combiner boxes
- Junction boxes
- AC and DC disconnects
- Tripped or damaged breakers
- Rapid shutdown equipment
- Electrical faults and system shutdowns
- Damage caused by animals or weather
Solar electrical repairs should always be performed by qualified professionals trained to work with photovoltaic systems, including high-voltage wiring, inverters, and other essential components. Solar equipment can be dangerous, so expert service helps ensure safe, code-compliant repairs and dependable performance.
Solar Battery and Energy Storage Service
Solar batteries add extra hardware, software, and device-to-device communication to an already complex home energy system. So if your battery won’t charge, won’t discharge when needed, or doesn’t provide the backup power you expect during an outage, the cause could be in several places. The problem might be the battery, the inverter, control equipment, or the monitoring platform. It could also come from network connectivity, system settings or operating modes, or basic electrical issues such as wiring, breakers, or other connections.
iSP Solar can evaluate problems such as:
- Battery not charging from solar
- Battery not providing backup power
- Unexpected battery shutdowns
- Communication and monitoring errors
- Inverter and battery integration problems
- Incorrect operating or backup settings
- Reduced storage availability
- System alerts or fault codes
- Solar and battery systems not working together properly
We’ll thoroughly assess your system, identify the component causing the problem, and explain what’s happening in clear terms. Then we’ll recommend the best next step—whether that’s routine maintenance, focused troubleshooting, or a specific repair to restore full performance.
Solar Panel Removal and Reinstallation for Roof Work
If your roof requires repairs or a full replacement, your solar panels may need to be safely and professionally removed before any roofing work begins. Once the project is complete, the panels can be properly reinstalled and reconnected to ensure everything is secure, aligned, and functioning as expected.
iSP Solar provides solar panel removal and reinstallation services for:
- Complete roof replacements
- Roof leak investigations
- Storm-damage repairs
- Flashing and roof-penetration repairs
- Structural roof work
- Chimney, skylight, or ventilation projects
- Home additions and renovations
Removing solar panels involves more than lifting modules off your roof. You also need to handle the wiring, racking, mounting hardware, and system layout carefully—and restore every weatherproof seal to protect your home and keep the equipment in good shape. Equally important, the system must be shut down safely, documented, and set up for a smooth restart later.
Once the roofing work is complete, we’ll reinstall the array to its original layout, reconnect all electrical components, confirm proper grounding and watertight seals, test system performance, and ensure your solar production is fully restored.
Roof Leaks and Solar Mounting Problems
A roof leak near a solar array doesn’t automatically mean the solar system caused it. In many cases, the roof itself is the real source—aging or failing materials, damaged or poorly installed flashing, existing roof penetrations, clogged or poorly designed drainage, storm or wind damage, or a problem elsewhere that lets water travel before it shows up near the panels.
Because iSP Solar understands both solar and roofing systems, we see the whole picture. We inspect the affected area, check mounting and attachment points, and confirm whether the solar array is causing the issue—or if the leak is coming from another source.
Service may include:
- Inspecting solar mounting points
- Evaluating flashing and roof penetrations
- Checking for loose or damaged mounting hardware
- Identifying visible roof or water intrusion concerns
- Removing panels when access is required
- Coordinating appropriate solar and roofing repairs
- Reinstalling and recommissioning the solar system

Critter Damage and Solar Panel Protection
Birds, squirrels, and other small animals sometimes nest under solar panels, leaving debris and increasing the risk of fire. They can also chew or damage exposed wiring, conduit, and other components, which can lead to expensive repairs and lower system performance.
Signs of animal activity may include:
- Debris collecting beneath the panels
- Nesting materials around the solar array
- Chewed or damaged wires
- Intermittent production problems
- Scratching or movement sounds from the roof
- Animals repeatedly entering beneath the array
iSP Solar will thoroughly inspect your system for visible animal-related damage, pinpoint problem areas, and recommend clear next steps. We repair damaged solar components, restore compromised wiring and hardware, and remove accessible debris to help return your system to safe operation. To reduce the risk of future issues, we also install durable solar critter guards that help keep animals from nesting under your solar array.
Storm and Weather Damage
Solar installations across New England and New York endure tough conditions year-round, including high winds, heavy rain, snow, and ice buildup. They also face falling branches, coastal storms, and frequent temperature swings that can affect long-term performance.
After a major weather event, contact iSP Solar if you notice:
- Broken or shifted panels
- Loose racking or mounting components
- Exposed or hanging wires
- New roof leaks
- Inverter alerts
- A sudden production drop
- Missing monitoring data
- Debris on or beneath the array
- Visible damage to electrical equipment
Never climb onto the roof or touch exposed solar wiring for any reason. Solar panels can keep producing electricity whenever light hits them, even if the inverter is off or part of the system is shut down. Treat every solar component as live until a qualified professional verifies the system is fully de-energized and safe to approach.
Solar System Maintenance and Performance Checks
A solar system can benefit from professional maintenance even when it seems to be working normally. Regular inspections catch small issues early, improve performance, and help key components last longer.
System maintenance and performance services may include:
- Production and performance reviews
- Visual solar panel inspections
- Inverter and microinverter checks
- Wiring and connection inspections
- Monitoring system verification
- Racking and mounting inspections
- Debris and shading assessments
- Critter-damage inspections
- Solar panel cleaning when appropriate
- Recommendations for repair or preventive maintenance
A performance check is especially helpful if you’re buying a home with an existing solar system, getting ready to sell a solar-powered property, evaluating an older system, or trying to understand unexpectedly high electric bills.
