ERA5 & Climate Blending
We analyze hourly wind speeds and solar irradiance at your site's exact GPS coordinates across a 10-year historical dataset to capture worst-month seasonal deficits.
Engineering & System Modeling
Renewable Energy Sizing Tool
Precision off-grid wind, solar, and hybrid power calculations for mission-critical remote infrastructure worldwide.
Engineering Precision
Eliminate Downtime with Data-Driven Sizing.
Under-sizing an off-grid system leads to costly winter power failures, while over-sizing inflates capital expenditure. Leading Edge Power's proprietary sizing methodology blends NASA temperature models, ERA5 climate reanalysis data, and the Global Wind Atlas to deliver continuous, 24/7 autonomous power.
Battery Chemistry Sizing
Calculations adjust for temperature-dependent battery capacity losses, depth of discharge (DoD) limits, and cycle-life retention across AGM and Lithium (LiFePO4) chemistries.
Hybrid Autonomy Margin
Where wind or solar alone cannot satisfy continuous load profiles, our algorithms calculate automatic methanol fuel cell back-up activation thresholds.

Sizing Workflow
Engineering Your Custom Power Profile.
Our engineering team follows a systematic multi-step verification process to ensure zero operational downtime for your international infrastructure projects.
Load Profile Audit
We analyze your hourly continuous consumption (Watts), surge currents, duty cycles, and operating DC/AC voltages to establish true base load requirements.
GPS Resource Assessment
Using site coordinates, we pull localized wind speed distributions (Weibull shape & scale parameters) and solar irradiation data for the past decade.
Storage & Back-up Design
Battery capacity is calculated for worst-case weather windows, adding reserve headroom and automatic fuel-cell triggers if safety-critical reliability is mandated.
Enclosure & Integration
Systems are packaged in marine-grade IP65/IP67 enclosures engineered to endure extreme temperatures, salt fog, and violent storms.
Technical FAQs
Frequently Asked Questions by Procurement Teams.
Our sizing tool models site-specific wind and solar resource data from ERA5 reanalysis blended with Global Wind Atlas datasets. Rather than using annual averages, it sizes system generation and autonomy based on worst-month winter solar yields and historical wind deficits, ensuring 99.9% operational uptime.
To receive an exact system sizing proposal, you need site coordinates (latitude/longitude), continuous base load (Watts), peak load demands, operating voltage (12V, 24V, or 48V DC), and required battery autonomy days.
Yes. The sizing methodology factors in temperature derating for batteries, salt-spray exposure derating, and high-wind survivability constraints using our marine-grade wind turbines and IP67 enclosures.
All micro wind turbines, solar framing, charge controllers, and custom power enclosures are designed, built, and tested at our manufacturing facility in Herefordshire, United Kingdom, to ISO-aligned quality standards before global dispatch.
