Is My Home Solar System Producing Power? Start Here

What “Producing Power” Actually Means

Before troubleshooting, clarify the question.

Producing power = your solar panels are actively generating electricity (measured in kW).

Lowering your bill = depends on production, how much power your home uses, your utility rate, time of year, and billing structure.

It’s possible for your system to be producing power while your bill remains high — especially:

• During winter months

• During heavy AC usage in summer

• After adding an EV

• After utility rate increases

This article focuses on one question:

Is your home solar system producing power at all?

If the answer is yes but your bill is still high, that’s a different issue — and we address that in the FAQ below.

Step 1: Check Your Solar Monitoring App

If your system includes monitoring (most do), this is the fastest way to confirm whether your home solar system is producing power.

Common Monitoring Platforms

• Enphase Energy → Enlighten

• SolarEdge Technologies → SolarEdge Monitoring

• Tesla → Tesla App

• SunPower → mySunPower

• SMA Solar Technology → Sunny Portal

If you bought your home with solar and aren’t sure which brand you have, check the label on the inverter box. It’s usually in your garage, on an exterior wall near the meter, or in a utility room.

The brand name will tell you which monitoring app to use.

What to Look For

• Real-time production (kW reading during daylight)

• Daily production graph

• Recent 7–30 day activity

• Error alerts or “system offline” messages

Red Flags

• Production stuck at zero during sunny days

• No data for multiple days

• “Inverter offline” errors

• Repeated fault notifications

Can’t access the app?

Search your inbox (and spam folder) for “solar,” “monitoring,” “inverter,” or your inverter brand. Manufacturers often send alerts about system faults, platform migrations, and monitoring changes.

Many homeowners assume their solar system stopped producing when only the monitoring platform changed. A quick email search can clarify that fast.

Step 2: Check the Inverter Directly

Your inverter is the heart of your system. If it’s not operating, your solar system is not producing power — regardless of what the panels are doing.

Where It’s Located

• Garage wall

• Exterior wall near meter

• Utility room

• Basement

Not sure which brand you have? Look for the manufacturer label on the unit itself. Common brands include Enphase, SolarEdge, SMA, Fronius, and Tesla.

What to Check

• Green light / “Normal” status → typically good

• Red light / “Fault” → issue

• Blank screen → possible shutdown or failure

• 0 kW output during sunny conditions → likely problem

If it’s sunny and your inverter reads zero output, that’s a strong signal your system is not producing electricity.

Step 3: Check Breakers and Disconnects

Solar systems have multiple shutoff points for safety.

Inspect:

• Main panel breaker labeled “Solar” or “PV”

• Solar sub-panel (if installed)

• Exterior disconnect box

• AC disconnect near inverter

Make sure:

• Breakers are fully ON (not halfway tripped)

• Disconnects are ON

• Nothing appears burned or damaged

If a breaker trips immediately after resetting, stop and call a professional. That usually indicates a real electrical fault.

Step 4: Look for Obvious Physical Issues

From ground level only:

• Fallen branches

• Debris covering panels

• Heavy snow

• Damaged conduit

• Recent electrical work nearby

Physical obstructions or electrical disruptions can completely stop production.

Step 5: Confirm How Much It’s Producing

If your system is producing power but not as much as expected, consider:

• Seasonal drops (winter production can be 40–60% lower than summer)

• New shading from trees or nearby construction

• Normal panel degradation (gradual over decades)

• A failed microinverter or optimizer

Panel-level monitoring — common with Enphase and SolarEdge systems — can reveal individual panel failures without shutting down the entire system.

Step 6: Decide Whether to Call a Professional

Contact a technician if:

• Production has been zero for multiple sunny days

• Your inverter shows persistent fault codes

• Monitoring hasn’t updated in weeks

• Breakers repeatedly trip

• Your bills increased with no change in usage

This doesn’t automatically mean expensive repairs. Sometimes the solution is as simple as a reset, firmware update, or reconnecting monitoring to your home network.

Common Reasons Solar Systems Stop Producing

Most issues fall into predictable categories:

• Inverter failure (common after 10–15 years)

• Tripped breaker

• Monitoring disconnected from internet

• Utility disconnect after electrical work

• Failed microinverter

• Installer out of business (hardware is usually still supported by the manufacturer)

The good news: most are repairable without replacing the entire system.
