What it is
"Solar panels not producing" usually means your system is generating much less power than expected, or none at all. You might notice it as a zero reading in a monitoring app, an inverter showing a fault light, or a utility bill that looks higher than usual.
Many things can cause this. Common ones include shade from new tree growth, dirt or debris on the panels, a tripped breaker or switch, an inverter that has shut down, a lost internet connection that only makes the app look like nothing is happening, or a loose or damaged connection somewhere in the system.
Output also naturally rises and falls with weather, season and time of day, so a low reading is not always a fault. Overcast days, snow cover and short winter days can all lower production without anything being broken.
How it’s traditionally been approached
Many homeowners start with the basics: checking the monitoring app, looking at the inverter display for a status light or error code, and confirming that the system's breakers and disconnects are in their normal positions. Reading the manual or the installer's quick-start guide is also a common first step.
Others contact the original installer or the manufacturer, especially if the system is under a workmanship or equipment warranty. Warranty terms differ, so it helps to keep your paperwork handy and read what it covers.
For anything that involves opening equipment, handling wiring or working on a roof, the traditional path is a qualified, licensed technician. Solar systems carry high-voltage direct current even in daylight, and roofs add fall risk, so these are not areas for improvised fixes.
How the right repair pro may help
The right solar panel repair or electrical pro may be able to test the system, read inverter fault codes, check connections and look for signs of shading, damage or failing components. A roofer may also be useful if a leak, loose mounting or damaged roof area is part of the picture.
A visit is generally a conversation first: what you have noticed, when output dropped, and whether anything changed, such as a storm, tree growth, roof work or a power outage. The pro may then inspect the equipment and explain what they find in plain language.
Good questions to ask include: Are you licensed and insured for this work in my area? Will you give a written estimate before starting? What do you think is causing the drop, and how would you confirm it? Does this affect my warranty? Are permits or utility notification required? Costs vary, so get details in writing.
The bigger picture
A system that is not producing can be frustrating, especially when you counted on it to help manage household bills. It is normal to feel worried or impatient, but a calm, step-by-step approach usually serves you better than rushing into a fix.
Knowing what you can safely check yourself, and when to hand things to a professional, can bring real peace of mind. If the expense is a concern, Providers.plus may be a place to explore broader resources, and taking time to compare written estimates is a reasonable way to stay in control of the decision.
Keep in mind
- Never climb on a roof or open inverters, combiner boxes or electrical panels to troubleshoot; these are dangerous and usually require a licensed pro.
- If you smell burning, see scorch marks, hear buzzing or notice smoke, stay away from the equipment and call 911 or your local emergency services.
- Licensing and permit rules for solar and electrical work vary by state and local area, so confirm a pro's license and insurance before hiring.

Frequently asked questions
Why are my solar panels not producing any power?
Common reasons include a tripped breaker or shutoff, an inverter that has shut down or shows a fault, heavy shade, snow or debris, or a damaged connection. Start by checking your monitoring app and inverter status light from the ground. If the cause is not obvious, a licensed solar or electrical pro can diagnose it safely.
Why are my solar panels producing less than usual?
Lower output can come from weather, season, shade from growing trees, dirty panels, or a failing component. Compare today's reading with similar sunny days rather than cloudy ones. If the drop continues, ask a solar repair pro to inspect the system.
Can I fix solar panels that are not producing myself?
Only simple, low-risk checks are suited to DIY, such as looking at your monitoring app or confirming the inverter has power and a normal indicator light. Wiring, inverters and rooftop work involve high voltage and fall risks, so they usually require a licensed professional.
Do solar panels stop working when the power goes out?
Many grid-tied systems shut down automatically during a utility outage for safety, so panels may appear not to produce even though nothing is broken. Systems with certain battery setups may behave differently. Check your installer's documentation or ask a pro how your system is designed.
Who do I call when my solar panels are not producing?
Start with your original installer or manufacturer if the system may still be under warranty. Otherwise, a solar panel repair and service company or a licensed electrical pro may help. If roof damage is involved, a roofer may also be needed.
What should I ask a solar repair pro before they start?
Ask whether they are licensed and insured in your area, how they will diagnose the problem, and whether they provide a written estimate. Also ask how the repair might affect your warranty and whether permits or utility notification are needed.
