Solar System Not Producing? What to Check Before You Call for Service
You open your monitoring and see zero production, an error code, or a battery that says offline. It is one of the most common reasons homeowners in Connecticut and Massachusetts reach out to Earthlight’s service team. These are actually three different problems, and a few quick checks can tell you which one you are dealing with.
Check Your Main Disconnect and Breakers First
The first thing to check is your main disconnect. If another contractor has worked at your house recently, such as an electrician, plumber, or HVAC tech, they may have shut off your solar at the main disconnect and forgotten to turn it back on. Make sure the switch is in the on position. Next, look inside your solar electrical box for any tripped breakers.
Is Your System Offline or Showing an Error?
An offline system is often a Wi-Fi problem, not a solar problem. If you recently changed your internet provider, router, or network name, your monitoring equipment lost its connection. You can usually fix this yourself by rebooting your monitoring platform, and your monitoring app will walk you through reconnecting to the new network.
An error is different. It usually means there is a fault somewhere in the system, and that is when you should call for service.
What Our Service Team Needs From You
The most helpful thing you can tell us is which monitoring system you have. If you are an Earthlight customer, we can look it up for you. If another company installed your system, take clear pictures of your solar electrical equipment, including the inverter, disconnect, and any battery, and send them in. Photos help us identify your equipment, especially on older battery systems from companies that are no longer in business.
Earthlight services systems we did not install, including many former SunPower and Sunnova systems. Read more about service for orphaned solar systems.
Frequently Asked Questions About Solar System Problems
Why is my solar system not producing, showing an error, or showing an offline battery?
These are three separate issues. No production often means the main disconnect was switched off or a breaker tripped. An offline system usually means your monitoring lost its Wi-Fi connection. An error typically points to a fault in the system that needs a service visit. Check your disconnect and breakers first, then call us if the problem continues.
Can I reconnect my solar monitoring to new Wi-Fi myself?
Yes, in most cases you can. If your system went offline after you changed your Wi-Fi network, reboot your monitoring platform. Your monitoring app will then walk you through connecting to the new network. If it still will not reconnect, contact our service team and let us know which monitoring system you have.
Do you offer system monitoring, an app, or a monthly report?
Yes. Your monitoring can be set up to send you a monthly report on how your system is performing. Earthlight also has plans for an app in progress, with a rollout expected in early 2027. Until then, our service team can help you read your monitoring and spot any issues.
Can someone come check my solar system once a year?
Yes. Homeowners, especially those whose original installer has gone out of business, often ask us to come out and make sure everything looks good. We will send a technician to inspect the system and flag anything that is not safe or not installed properly. This is typically billed as a one-hour service call.
Do you service solar systems you did not install?
Yes. Earthlight services systems installed by other companies, including systems whose installer has closed. Most former SunPower and Sunnova leases are now managed by SunStrong Management, and Earthlight is a current service provider for SunStrong. Some companies require an approval form, which we complete. A small number of brands we cannot work on, so call us to confirm.
