Solar Installation Contractors in Pewaukee, WI

For most Pewaukee homeowners, yes. A properly sized array can offset 60% to 100% of your annual electricity, and net metering through We Energies credits you for the surplus your panels send back to the grid. With current incentives, typical payback lands in the 7-to-10-year range — and the system keeps producing long after that.

Absolutely. We're based in Wauwatosa at 12012 W Fairview Ave — about 15 miles east of Pewaukee via I-94 — and we cover the whole city: the Village of Pewaukee, the Lake Pewaukee shoreline, the Capitol Drive corridor, the Lake Country subdivisions, and the wooded and rural lots throughout the 53072 ZIP code.

The City of Pewaukee requires a building permit for any solar installation. Lehmann Electrical handles the entire process — filing the permit with the City of Pewaukee, submitting interconnection paperwork to We Energies, and scheduling every required inspection. Start to finish, permitting and interconnection usually take about 4 to 8 weeks.

Sometimes. Many of Pewaukee's older Village and lakefront homes still have 100-amp service that may lack the headroom for solar backfeed, and homes built before the 1980s are the most likely to need an upgrade to 200 amps. We include a free load assessment with the site evaluation so you know up front whether an upgrade is required.

The hands-on installation is quick — usually 1 to 3 days on site. The full timeline from first consultation to system activation, including City of Pewaukee permitting and We Energies interconnection, generally runs 8 to 12 weeks. Larger commercial systems can take a little longer depending on size.

They keep producing year-round. Snow typically slides off panels set at a normal pitch, and light cover melts away quickly once the sun hits them. Modern panels are rated for heavy Wisconsin snow loads, and while output dips during the shorter winter days, our annual production estimates already account for the seasons.

When your panels make more electricity than your home is using, the extra flows back to the grid and We Energies credits your account. At night or on cloudy days you draw from the grid, and those credits offset the cost. It's what lets a well-sized Pewaukee system effectively cancel out much of your yearly bill.

Pewaukee homeowners may qualify for the federal clean-energy tax credit, Focus on Energy rebates, and We Energies utility programs. Because availability and amounts change periodically, we review every option that currently applies during your consultation and help you claim the ones you're eligible for.

Yes. Batteries like the Tesla Powerwall and Enphase IQ can be paired with a new system or added to an existing one. They store your surplus solar production for outages or peak-rate evenings — a practical upgrade for Lake Country and rural Pewaukee homes that see occasional storm-related grid interruptions.

Once or twice a year is typical — usually in spring after pollen season and again in fall once the leaves drop. Homes along the Lake Pewaukee shoreline or under heavy tree canopy may need it a bit more often. Soiling can quietly trim output by 5% to 25%, so periodic professional cleaning keeps the system performing.

Today's panels are built to last 25 to 30 years. Most tier-one manufacturers still guarantee at least 80% of original output at the 25-year mark, with degradation of only about 0.5% per year. With routine maintenance, systems typically keep generating well beyond their warranty period.

Definitely. Solar-powered EV charging offsets most or all of your driving energy costs, and we design integrated solar-plus-EV systems with the panel capacity planning both need. Many Pewaukee homes with attached or detached garages are excellent candidates for coordinated solar and charger wiring.

Solar is, at its core, electrical work. An electrician-led company gets the wire sizing, code-compliant connections, and inspection-ready installations right the first time — without callbacks. That expertise matters in Pewaukee, where older homes can have undersized panels or dated wiring a solar-only installer isn't equipped to handle.
