✅ Annual Checkup: What Owners Need to Monitor for Maximum Output

While solar panels require minimal upkeep, a yearly check can prevent small issues from turning into major performance losses.

1. The Quarterly Visual Inspection (DIY)

Look for obvious external problems from the ground using binoculars.

• ✅ **Shading:** Check for new growth on nearby trees or bushes that may be casting shadows, especially during winter months.
• ✅ **Cleanliness:** Note any heavy accumulations of bird droppings or dust that haven't been washed away by rain.
• **Hardware:** Look for any visible damage, loose wires, or signs of pest intrusion (e.g., nesting materials under the panels).

2. The Annual Professional Checkup

A certified technician should perform a deeper system assessment.

• **Inverter Check:** Inspecting the inverter for error codes, unusual noise, or signs of water damage.
• **Wire Integrity:** Checking all DC and AC wiring connections, conduit, and grounding for corrosion or loose connections.
• **Performance Audit:** Comparing current production data against the predicted output to identify any hidden problems with individual modules or optimizers.

Monitoring is Your Best Tool

Your system's mobile monitoring app is the most effective maintenance tool. Check it weekly—any sudden, unexplained drop in daily output is the first and clearest sign that a component (like a micro-inverter or panel) is failing or a shadow has appeared. 💡
