Solar Assure is headquartered at 1200 Lake Saint Louis Boulevard, three minutes from the Civic Center, five minutes from The Meadows. Josh and Tori are LSL residents. When you're booking solar for a house on Lake Saint Louis or Lake Sainte Louise, you're not calling a national outfit. You're calling your neighbors. This is the only city in our service area where we can honestly say we drive past most of our installs on the way home from Schnucks.
Custom savings breakdown for your LSL home. No credit pull. No pressure. We already live here.
The majority of "local" solar companies advertising in St. Charles County are actually national installers with a Missouri mailing address and a call center in Phoenix or Dallas. Solar Assure is different. Our LLC is registered at 1200 Lake Saint Louis Boulevard, Suite 1016, our crews live in the STL metro, and our founders Josh and Tori walk their dog past The Meadows on weekends. When your solar system has a question or needs follow-up three years from now, we're not a 1-800 line. We're a business you could, in principle, walk into.
This matters because solar is a 25-year relationship with whoever installed it, not a one-time purchase. Our BBB A+ rating and 4.9-star local reviews exist because when something needs attention, we can physically be at your house. That's a real advantage you don't get from national brands.
1200 Lake Saint Louis Blvd, Suite 1016 · Lake Saint Louis, MO 63367Lake Saint Louis was designed from scratch in 1961 as a private weekend resort community. Sixty-plus years later, it's one of the most affluent cities in St. Charles County, with higher homeownership than the state, higher incomes than the region, and housing stock that's been carefully maintained by people who plan to stay. These are exactly the conditions where a 25-year solar investment pays back fastest.
Both lakes were created by damming Peruque Creek, a tributary that now feeds the entire community's defining feature. Waterfront homes have different considerations than inland homes: open yards for lake views mean unobstructed roof exposures, and water-reflected light can actually boost certain roof orientations. Here's the breakdown.
The smaller, quieter of the two lakes. Built first, before its bigger sibling. Stricter boating rules (no high-speed watercraft) and more restrictive waterfront covenants. Homes around Lake Sainte Louise tend to be the original 1970s-era builds, refreshed over the decades. Solar note: mature tree canopy common. We always run shade analysis carefully on these homes.
The big one. Dam completed 1972, and it's 7x larger than Lake Sainte Louise. The lake you see on city maps. Higher speed limits, more boat activity, full marinas. Homes range from 1970s originals to newer custom builds. Solar note: waterfront homes often have rear-roof exposures facing south across the water, which can be excellent for panel placement.
Lake Saint Louis's neighborhoods were developed in distinct phases starting in 1968. Each has its own architectural character, roof style, and HOA posture toward solar. We've done installs in all of them. Here's the lay of the land.
The original core of Lake Saint Louis. This is literally where the city incorporated as "Town of Harbor Town" in 1975 before being renamed. Waterfront homes with LSLCA covenants. Simple ranch and split-level roof geometries that typically make for clean, fast installs.
Mix of waterfront and near-water homes. Larger lots, mature landscaping. LSLCA architectural review applies. We've done dozens of installs here, and the HOA process is predictable once you know the rhythm.
Near Lake Forest Country Club. Larger homes with generous lot sizes. Good south-facing roof exposures common. Some homes back up to the golf course fairways, so open sky on the south side is ideal for panel production.
Newer residential around The Meadows lifestyle center. Built after 2008, these homes typically have modern 200-amp panels and straightforward roof lines. May be on Ameren rather than Cuivre River, and we check upfront.
Post-2000 developments east of the original community. Newer housing stock means modern electrical systems, simpler roofs, and less mature tree canopy to worry about. Often our fastest LSL installs.
Waterfront homes in LSL have special considerations: LSLCA covenants, view-easement rules, and unique roof orientations (often facing the lake rather than the street). We've done waterfront work on both lakes, so we know the nuances.
In January 1961, Ellis Ellerman and Ira Nathan sat down to plan a weekend resort community around a private lake. They'd need to dam Peruque Creek, a tributary running between Wentzville and O'Fallon, to create the water body big enough for boating. Construction on the first dam (Lake Sainte Louise) finished in 1969. The bigger one (Lake Saint Louis proper) was completed 1972. Between them, they created 685 acres of new freshwater and 14 miles of new shoreline on land that had been farmland.
R.T. Crow, the main developer, filed Chapter 11 bankruptcy in 1974 during the energy crisis. The community banded together in 1975, and the founding residents of Harbor Town petitioned for incorporation to avoid being annexed by Wentzville or O'Fallon. That collective, we-built-this-ourselves spirit is still the defining quality of LSL. Solar is a similar kind of bet: locking in energy independence for the next 25 years, on your own terms, regardless of what happens to Ameren's rate case or Cuivre River's fuel adjustment. Very on-brand for your city.
This surprises people moving in from St. Charles or Chesterfield: Lake Saint Louis is primarily Cuivre River Electric Cooperative territory, not Ameren. CREC even has its Lake Saint Louis branch office at 8757 Highway N, right in town. Newer developments south of I-64, especially around The Meadows, may be on Ameren Missouri. We verify your specific address at the start of every quote.
Your utility dictates your interconnection process, net metering rules, and long-term rate trajectory. Here's the lay of the land for Lake Saint Louis specifically:
Missouri's largest consumer-owned electric cooperative, serving 68,000+ members across Lincoln, Pike, St. Charles, and Warren counties. As a member you own part of it. CREC has a dedicated Lake Saint Louis branch at 8757 Hwy N. Different net metering terms from Ameren, and we know the CREC interconnection packet well. Co-op structure can mean rebates or credits are occasionally available (check each year).
Missouri's largest investor-owned utility. Net metering at full retail rate for self-consumption (~12.64¢/kWh). Excess export paid at 5.39¢/kWh summer, 3.92¢/kWh winter. Rebate expired Dec 31, 2023. +12% rate hike effective June 2025. Interconnection typically 30-90 days. The newer developments around The Meadows and Hawk Ridge corridor are more likely on Ameren.
Lake Saint Louis has slightly more paperwork than a typical MO city because of the LSLCA, but we've done this enough times that it's routine. Here's the actual timeline.
Lake Saint Louis is our HQ, but our installers go out across Missouri and Kansas daily. Here are our other published city guides.
Real calculations on your address, your roof, your Cuivre River or Ameren bill. We'll tell you straight whether solar makes sense for your home, as your neighbors, not a salesperson.
