What happens if my roof needs replacement after solar is installed?

If the roof needs replacement during the life of the solar system, the panels are detached, the roofing work is completed, and the panels are reinstalled. Most roofers charge $500 to $1,500 for the detach and reset on a typical residential solar array. A roof condition assessment during the initial solar quote helps identify and avoid this scenario upfront.

The Ameren rate trajectory

Your bill didn't just go up. It's been climbing for years.

These aren't predictions. They're public rulings from the Missouri Public Service Commission, reported by the Missouri Independent, St. Louis Public Radio, and the Consumers Council of Missouri. The pattern is clear, and the next rate case is already being planned.

Ameren summer bills up 34.5%Over five years the average Ameren residential summer bill climbed 34.5%, and winter bills rose 32.9%, according to a Consumers Council of Missouri analysis. That works out to roughly 6% per year, outpacing both general inflation and local Missouri wage growth over the same period.

Missouri Senate Bill 4 becomes lawGovernor Mike Kehoe signed SB4 into law in April 2025. Among other changes, it lets utilities charge customers for "Construction Work in Progress", meaning you pay now for power plants that won't produce electricity for 5 to 10 years. Consumer groups estimate the typical Missouri household will pay roughly $1,000 more per year over time due to the changes.

Ameren's +12% rate hike takes effectThe Missouri Public Service Commission approved a $355 million annual rate increase for Ameren Missouri, raising bills about 12%, or $14 to $20 per month for a typical residential customer. Over a full year that adds up to $175 to $240 more, for the same electricity you were already using.

Amazon announces 1,000-acre data centerAWS announced Project Green, a 1,000-acre data center campus in Montgomery County, one county west of St. Louis. A second unnamed project (Project Spade) adds another 780 acres. Combined, these sites will draw power roughly equivalent to 100,000 homes each, based on International Energy Agency estimates for large-scale data centers. Ameren Missouri will provide the electricity.

More capacity. More infrastructure. More rate cases.Ameren is now studying plans to double its nuclear generation capacity over the next two decades to serve new large loads. Consumer advocates have already filed a motion for reconsideration of the data center rate plan, arguing the protections don't go far enough to shield residential customers from cost-shifting. The Missouri Office of Public Counsel's chief economist has been quoted warning that SB4 "will enable more cost spend" that ratepayers will ultimately bear.

What solar actually does

Solar isn't cheaper power. It's stable power.

A lot of solar pitches lead with "save 90% on your bill!" That claim is misleading. The real math is simpler and more honest: your solar-generated electricity costs roughly the same today, but it stays that way for 25 years while Ameren's rate keeps climbing.

Compound a 6% annual rate increase for 10 years and your electric bill nearly doubles. Compound it for 25 years and it's close to 4× what you pay today. Meanwhile, your solar panels produce the same kilowatt-hours in year 25 as they do in year 1, at a cost you locked in on install day.

Common questions

The real questions Missouri homeowners ask.

Did Ameren really just raise rates, or is this marketing?

Yes. On April 23, 2025 the Missouri Public Service Commission approved a $355 million annual rate increase for Ameren Missouri, raising the average household bill about 12 percent or roughly $14 to $20 per month starting June 1, 2025. The ruling is public record, searchable at psc.mo.gov under the 2025 Ameren rate case, and was covered by the Missouri Independent, St. Louis Public Radio, and the St. Louis Post-Dispatch.

How do data centers affect my electric bill?

Data centers typically push residential electric rates higher because utilities expand grid capacity and generation to serve large industrial loads, then recover those costs through base rates. In November 2025 the Missouri PSC approved a large-load tariff intended to make data centers pay more of their own costs, but the Consumers Council of Missouri has filed a motion for reconsideration arguing the protections do not go far enough. Senator Josh Hawley has also said publicly that Big Tech should cover its own infrastructure costs. Even if the tariff works as designed, Ameren is planning grid upgrades and potential nuclear expansion, and those costs typically find their way into base rates over time.

Will my $0-down monthly payment really be lower than my Ameren bill?

For most single-family Missouri homes with an Ameren bill above $180 per month, yes. The $0-down monthly payment typically comes in below the current Ameren bill starting day one. Smaller homes with bills under $120 often start close to break-even and then pull ahead as Ameren rates continue climbing. Your free quote models your specific address, current usage, roof orientation, shade, and the system size we'd design, so you see both the day-one numbers and the 25-year projection before you commit to anything.

What if I sell my house?

Owned residential solar typically adds value at the time of sale. A study by the Department of Energy's Lawrence Berkeley National Laboratory found homes with owned solar sold for a premium over comparable non-solar homes, often exceeding the remaining loan balance. If financed, the loan is either paid off at closing from sale proceeds or assumed by the qualifying buyer. We walk through both scenarios during your quote so there are no surprises.

Why go with Solar Assure instead of a bigger national company?

Solar Assure is a family-run installer based in Lake Saint Louis where the founders personally handle every project. When you call, Joshua or Tori Hayeslip answer directly rather than a rotating call center, and installs are handled by local Missouri crews we know personally rather than out-of-state subcontractors. The big national companies run on volume. We run on referrals from happy customers, which means we have to get every install right.

Does solar actually work in Missouri's winter?

Yes. Missouri averages roughly 4.5 to 5 peak sun hours per day across the year, including winter months, which is sufficient for residential solar to produce meaningful output year-round. Production dips in December and January and peaks in June and July, and modern panel warranties cover 25 years of generation across all seasons. Cold temperatures actually improve panel efficiency slightly. Snow cover is typically short-lived on a tilted residential roof, and the Enphase monitoring app shows you exactly what each panel produces day by day.

What happens if my roof needs to be replaced later?

If the roof needs replacement during the life of the solar system, the panels are detached, the roofing work is completed, and the panels are reinstalled. Most roofers charge roughly $500 to $1,500 for the detach and reset on a typical residential array. A roof condition assessment is part of the initial solar quote, and if your roof is nearing end of life we'll recommend replacing it first to avoid this scenario entirely.

What about the federal tax credit I keep seeing ads for?

The 30 percent federal residential solar tax credit expired on December 31, 2025 for cash and loan purchases under the One Big Beautiful Bill Act, which was signed into law in July 2025. Any company still advertising it for new 2026 purchases is either referring to the separate lease or PPA provision (which remains available through 2027) or being misleading.

Josh founded Solar Assure in Lake Saint Louis to bring residential solar to Missouri families without the high-pressure tactics of national sales organizations. He personally handles system design and the initial quote for every customer.
