THE PRAIRIE FORT DIFFERENCE
HERMIA INTELLIGENCEKERAUNOSby Hermia
Intelligence before
the first inspection.
The storm is the starting signal.
Your home is the focus.
Keraunos brings weather intelligence, property insight, and field operations into one storm-response platform. Built by Hermia, it gives Prairie Fort a distinctive foundation for more informed roofing and solar care.
From radar to roof, the value is a connected picture: where a storm passed, which properties deserve attention, and what the inspection actually found.
Start with your propertyTHE INTELLIGENCE JOURNEY
01 / 04
Read the storm as it unfolds.
Keraunos combines radar-derived hail estimates, severe-weather warnings, and reported observations to build a picture of a storm’s footprint.
- Radar hail estimates
- Weather warnings
- Storm reports
What this means for your home
Earlier awareness of areas that may need a closer look—and useful storm context before an inspection begins.
The roof. The solar. One home.
A storm can affect the roof and the energy system above it. Solar-array detection is being developed to help identify panel-equipped properties in a storm’s path.
A record that stays connected.
Hermia’s local-first architecture supports control over property records, consent, and field history—so information can follow the work.
Built for the work ahead. Keraunos’s core platform is running. The Prairie Fort website connection, solar-array detection, and expanded reporting are in development.
Grounded in inspection. Radar estimates storm exposure. A professional inspection establishes the condition of your roof and solar equipment.
AFTER THE STORM
The weather is uncertain.
Your next step shouldn’t be.
When hail or wind passes through, knowing where to start makes all the difference. We help you understand your roof’s condition and the options in front of you.

THE PRAIRIE FORT APPROACH
After the storm, start with clarity.
Hail and wind can leave damage that is hard to see from the ground. Start with a roof assessment, understand what needs attention, and make a plan for the work ahead.

- Photos and clear explanations of findings
- Repair and replacement options for your home
SOLAR FOR ILLINOIS HOMES
Put your roof to work.
Bring your energy costs down.
Your roof can do more than shelter your home. A well-planned solar system can reduce the electricity you buy, with a design that starts with your roof, your usage, and your goals.
Explore my solar optionsBuy less grid electricity
Use the power your roof generates to offset household electricity purchases. The result depends on when you use energy and your utility rate.
Plan the roof and panels together
Coordinate roof life, panel placement, and installation timing to reduce the chance of removing panels for roof work later.
Generate renewable energy
Turn sunlight into electricity at home and support Illinois’ transition to renewable generation.
Consider backup power
A compatible battery and backup configuration can support selected circuits during outages. Standard grid-tied solar alone shuts down when the grid goes down.
Learn about solar’s benefits and solar with battery backup.
UNDERSTAND THE SAVINGS
Your bill tells the story.
Let’s look at the whole picture.
Solar’s value comes from electricity you use at home and credits for electricity you send to the grid. Those two amounts can have different values.
Illinois billing changed in 2025
New residential systems with ComEd, Ameren, and MidAmerican use supply-only net metering. Export credits do not offset delivery charges; fixed charges remain. Your utility and supplier determine the details. Read the current rules
What your solar proposal should explain
- Roof condition, shading, layout, and estimated yearly production
- Your utility rate, energy use, and expected export credits
- Installed cost, incentive pass-through, and payment terms
- Maintenance, warranties, and assumptions behind the payback estimate
ILLUSTRATIVE EXAMPLE
How solar’s energy value adds up
Assume a system generates 9,000 kWh in a year, with 6,000 kWh used at home and 3,000 kWh exported.
Used at home · ⅔Sent to grid · ⅓
- Electricity purchases avoided6,000 kWh × assumed $0.18/kWh
- $1,080
- Value of export credits3,000 kWh × assumed $0.07/kWh
- + $210
Illustrative annual energy value$1,290/ year
Before installation, financing, maintenance, and other project costs. This is not net savings, a quote, or a prediction for your home.
Production, usage, and rates above are hypothetical, not Illinois averages or current utility tariffs. Credits are assumed fully usable. No incentives, tax credits, or future rate increases are included. Your utility bill will still include applicable charges.
THE ILLINOIS ADVANTAGE
Solar incentives worth exploring.
Program information checked
Illinois Shines
Value from your RECs
The program pays Approved Vendors for renewable energy credits generated by qualifying projects. Your contract determines how much of that value reaches you through reduced costs or other savings.
Ask for the incentive amount, fees, timing, and customer pass-through in writing.
Explore Illinois ShinesUtility rebates
$300 / kW solar
Eligible residential solar with a smart inverter can receive $300/kW, plus $300/kWh for qualifying battery storage. Utility approval and equipment requirements apply.
Storage rebates have rate or program obligations. Existing full-retail net-metering customers can lose that benefit by accepting the generation rebate. Review terms first.
Review rebate conditionsIllinois Solar for All
No upfront solar cost*
Qualifying one- to four-unit properties can access solar without upfront installation costs through participating Approved Vendors. Single-family household income generally must be at or below 80% of area median income.
*Eligibility, property requirements, program funding, and contract terms apply. Confirm current availability directly with the program.
Check Solar for All eligibilityPlanning a homeowner-owned system in 2026?
The federal 30% Residential Clean Energy Credit is unavailable for property placed in service after December 31, 2025. A new homeowner-owned system should not be quoted with that credit. See IRS guidance
These are program summaries, not an incentive award or a claim of Prairie Fort program approval. Availability, compatibility, and the benefit passed to you depend on your project and contract. Confirm eligibility before signing.
