# Solar Panel Not Producing

If one or more panels stopped producing, it's usually one of a handful of causes. The fix ranges from a 5-minute reset to a panel or component replacement.

## Most common causes

- **Failed microinverter or optimizer**, most common cause when a single panel or small group stops producing.
- **Failed string inverter**, when the whole system goes dark.
- **Tripped breaker**, a one-time trip resets fine; repeated trips indicate a fault.
- **Soiling**, heavy bird droppings, leaves, or debris physically blocking light.
- **New shading**, tree growth or new construction casting shade where there was none.
- **Loose or corroded connections**, common at MC4 connectors after 5+ years.
- **Panel-level failure**, actual panel hardware failure (rare; modern panels are very reliable).
- **Snow cover**, temporary in winter; usually clears within a day or two.

## What you can check yourself

1. **Look at your monitoring app**, most modern systems show per-panel or per-string data. The app will often pinpoint the exact failed component.
2. **Check the inverter display**, error codes and fault lights help diagnose.
3. **Check the breaker panel**, solar breaker tripped? Reset once. If it trips again, stop and call.
4. **Look at the panels from the ground**, any visible damage, cracks, soiling, or shading?

## When to call a technician

- Repeated breaker trips
- Microinverter or optimizer fault that persists after power-cycling
- Production loss with no visible cause
- Any visible panel damage, cracks, or scorching
- Inverter older than 10 years with new fault codes (often indicates end-of-life)

## What we do

- On-site diagnostic with thermal imaging and IV-curve tracing if needed
- Component-level testing to identify the exact failure
- Warranty claim filing where applicable
- Same- or next-week replacement of common parts (microinverters, optimizers, inverters)
