Professional solar system evaluations to verify performance, spot problems, and confirm safety. Get complete inspection reports within 48 hours from licensed electricians.

Why You Need a Professional Solar Inspection

At Lehmann Electrical, we’ve noticed a growing problem in the Milwaukee area – poorly installed solar systems that don’t deliver promised performance. As master electricians who expanded into solar, we bring a unique perspective to solar inspections that panel-only companies miss.

Since 2020, we’ve checked everything from brand new installations to decade-old systems across Southeastern Wisconsin. Our inspections go beyond surface-level checks to identify hidden electrical issues that affect performance, safety, and longevity.

Whether you’re buying a home with existing panels, troubleshooting performance drops, or just confirming your system is working properly, our straightforward assessment will tell you exactly what’s happening with your solar investment.

Our 4-Step Solar Inspection Process

1. Visual System Assessment

We thoroughly examine all visible components for:

Panel condition (cracks, delamination, discoloration)
Mounting hardware security
Roof penetration quality and water sealing
Wire condition and proper management
Inverter/microinverter physical condition

Every inspection includes detailed photos documenting current condition.

2. Performance Testing

We measure actual system output against expected production:

Historical production data review
On-site output measurements
Shade analysis throughout the day
Individual panel performance tests
Inverter efficiency verification

Our testing identifies underperforming components and production bottlenecks.

3. Electrical Safety Verification

As master electricians, we check critical safety elements:

Proper grounding throughout system
Wire insulation integrity
Connection quality at all points
Disconnect functionality
Code compliance of electrical components

This electrical focus separates our inspections from general solar checks.

4. Documentation Review

We evaluate all system paperwork for completeness:

Original permits and inspection reports
Component warranties and transferability
Monitoring system setup and access
Utility agreements and interconnection documents
Past maintenance records

Proper documentation is essential, especially during property transfers.

Common Issues We Find in Milwaukee Solar Systems

Weather-Related Damage

Wisconsin’s harsh climate takes a toll on solar installations:

Hail impacts causing micro-cracks in panels
Ice dam formation under panels
Loose mounting from freeze-thaw cycles
Snow load damage to racking systems
Lightning surge impacts on electronics

Our local experience helps identify weather patterns that affect your specific location.

Installation Quality Issues

Unfortunately, we regularly find shortcuts taken during installation:

Improper roof attachments causing leaks
Insufficient wire management creating wear points
Incorrect panel spacing affecting cooling
Mismatched components reducing efficiency
Inadequate grounding creating safety hazards

These installation problems often remain hidden until professional inspection.

Performance Problems

Many systems produce significantly below capacity due to:

Tree growth creating new shading
Soiling from pollen, dust, and bird droppings
Inverter degradation
Panel efficiency loss beyond expected rates
Monitoring system failures masking issues

Most performance problems can be resolved once properly identified.

Documentation Gaps

Missing paperwork creates headaches, especially during property transfers:

Lost warranty information
Missing permits or inspection certificates
Incomplete monitoring system credentials
Undocumented system modifications
Expired interconnection agreements

We help identify and resolve documentation issues to protect your investment.

What Sets Our Solar Inspections Apart

We’ve worked with hundreds of local solar systems since 2020. We understand how Wisconsin weather patterns, local installation practices, and regional utility requirements affect performance.

Most home inspectors know little about solar. Most solar companies aren’t electricians. We bring both specialties to every inspection, catching electrical integration issues others miss.
