Proffesional Solar Panel Installation Services
Residential Solar Installation
Complete home solar installations designed for Wisconsin's residential market:
- Custom system sizing based on your household energy consumption and roof characteristics
- Installation on asphalt shingle, metal, and tile roofs with proper weatherproofing
- Integration with existing electrical service or coordinated with panel upgrades when needed
- Flush-mount and tilted racking systems depending on roof pitch and sun exposure
- Net metering setup with your utility company for bill credits on excess production
Most Wisconsin homes have enough south-facing roof space for meaningful solar production. We'll evaluate your property's solar potential honestly—if your roof faces the wrong direction or has too much shade, we'll tell you upfront. When conditions are right, we design systems that offset 60-100% of your annual electricity usage, depending on your goals and budget.
Commercial Solar Installation
Large-scale solar solutions for Wisconsin businesses and commercial properties:
- Roof-mounted systems for warehouses, retail centers, office buildings, and industrial facilities
- Ground-mount installations when roof space is limited or unsuitable for solar arrays
- Three-phase electrical integration for commercial and industrial power systems
- Coordination with utility companies for demand charge reduction strategies
Commercial solar makes the most financial sense when you have high daytime electricity usage that aligns with solar production hours. Warehouses, manufacturing facilities, and retail operations are ideal candidates. We'll analyze your utility bills and create a detailed ROI projection before you commit to anything—the numbers need to make sense for your business.
Roof & Site Assessment
Thorough evaluation to determine if your property is suitable for solar installation:
- Roof condition inspection to identify repairs needed before solar installation begins
- Shading analysis using solar pathfinder tools to measure tree and structure impacts
- Roof orientation and pitch measurements to calculate optimal panel placement
- Structural load capacity evaluation—solar panels add 3-4 pounds per square foot
- Electrical service capacity review to determine if upgrades are necessary
Here's what kills solar projects before they start: roofs that need replacement within five years, significant shading from mature trees, north-facing roof slopes, or electrical panels already at capacity. We catch these issues during assessment, not after you've signed contracts and pulled permits. If your roof needs work first, we'll tell you to handle that before adding solar equipment.
Electrical Integration & Wiring
Professional electrical work that connects your solar array to your home or business:
- Inverter installation and AC/DC disconnect switches for safe system operation
- Conduit runs from rooftop array to electrical panel following shortest practical path
- Panel breaker installation sized correctly for solar backfeed requirements
- Grounding and bonding to protect against lightning strikes and electrical faults
- Integration with battery backup systems when energy storage is part of the design
This is where being actual electricians matters. We're not just solar installers who learned enough electrical work to get by—we're licensed electricians who added solar to our skillset. That means proper wire sizing, correct breaker placement, code-compliant installations, and work that passes inspection the first time without callbacks or corrections.
Permitting & Utility Interconnection
Complete handling of paperwork, permits, and utility approvals required for solar:
- Building permit applications with local municipalities across Wisconsin
- Utility interconnection agreements with We Energies, Alliant Energy, and other providers
- Net metering enrollment to receive credits for excess solar production
- Electrical inspection coordination and any corrections needed for approval
- Permission to operate (PTO) from utility company before system activation
The permit and interconnection process takes 4-8 weeks on average in Wisconsin, though it varies by municipality and utility provider. We handle all the submissions, follow up on approvals, and schedule required inspections. You'll know what's happening at each stage, but you won't need to chase down paperwork or argue with the building department yourself.
