Hail & Severe Weather
Risk Assessment

Hail causes 54% of all solar insurance losses. Assess frequency, intensity, and financial exposure for any US location — before you commit to a site.

The Challenge

The $58 Million Problem: Hail Is Solar's #1 Financial Threat

Hail damage accounts for just 1.4% of solar insurance claims but a staggering 54% of total losses (GCube Insurance). The average solar hail claim now reaches $58.4 million. In March 2024, the Fighting Jays solar farm in Fort Bend County, Texas faced remediation costs potentially exceeding 50% of its initial construction value.

A single 2022 Texas hailstorm caused over $300 million in solar field damage. Insurance premiums in hail-prone regions have spiked up to 400%, with deductibles reaching $1 million or 15% of the physical damage limit. For developers in central US states, hail risk is the number one financial exposure.

The Earthflow Solution

Quantified Hail Exposure Before You Break Ground

Earthflow's hail and severe weather analysis combines historical frequency mapping, intensity zone classification, seasonal risk periods, and insurance cost modeling to give developers a complete picture of weather exposure — site-specific, not regional.
🌨️
Hail Frequency Mapping
Historical hail event frequency for any US location. Intensity zone classification, seasonal risk period identification, and probability curves based on NOAA severe weather data.
💨
Wind Exposure Analysis
Mean annual wind speed, peak gust analysis, extreme event probabilities, and wind load zone classification. Critical for tracker stow strategy planning and structural design.
🛡️
Insurance Risk Modeling
KPI-driven insurance premium calculations factored by location-specific hail exposure, wind vulnerability, and panel technology (mono-Si vs. thin-film). Base rate adjustments from 1.0x-3.0x.
📊
Integrated Hazard Scoring
Combined with seismic (PGA), flood (FEMA zones), precipitation intensity (Atlas14), and erosion risk (RUSLE) for a complete natural hazard profile per site.
The Impact

Data-Backed Risk Decisions Save Millions

When a single hail event can cause $50M+ in damage, pre-development site selection based on quantified hail exposure is not optional — it's essential. Effective hail stow protocols alone can reduce losses from $50M to below $5M per event.
$50M+
Avoidable Losses
Pre-development hail risk scoring helps avoid highest-exposure locations where single events have caused $300M+ in damage across solar fields.
1.0-3.0x
Insurance Adjustments
Site-specific data enables precise insurance premium negotiations instead of blanket regional rate increases up to 400%.
$45M
Stow Protocol Savings
Effective hail stow strategies reduce per-event losses from $50M to below $5M — but require accurate wind and hail data to implement correctly.
Complete
Hazard Profile
Hail, wind, seismic, flood, precipitation, and erosion risk in a single assessment. No need for separate weather consultants.
