Solar & Wind Farm Inspection
AI-Powered Autonomous Inspection for Maximum Energy Production, Reduced Downtime, and Optimized O&M Costs
The Renewable Energy O&M Challenge
Renewable energy assets demand maximum uptime and performance to meet production targets and revenue projections. Yet traditional manual inspection methods are slow, expensive, dangerous, and miss defects that silently erode energy production for months or years.
RAVAM transforms solar and wind farm operations through autonomous aerial inspection powered by RAVAM AI—detecting every defect, preventing catastrophic failures, and optimizing performance across entire portfolios.
Hidden Production Losses
Defective solar panels, soiled modules, and underperforming strings silently reduce energy output for months. Manual spot-checking misses most problems.
Slow & Expensive Inspection
Manual inspection requires days or weeks per site, rope access for turbines, and specialized equipment—limiting frequency and coverage.
Catastrophic Blade Failures
Small cracks and erosion go undetected until catastrophic failure occurs—causing extended downtime, expensive repairs, and safety risks.
Worker Safety Risks
Climbing wind turbines and walking solar arrays exposes technicians to falls, electrical hazards, and extreme weather conditions.
Limited Portfolio Visibility
Asset owners managing multiple sites lack comprehensive, consistent data to prioritize maintenance and capital investments across portfolios.
Performance Guarantee Penalties
Production falling short of PPA (Power Purchase Agreement) commitments results in revenue loss and contractual penalties.

- Annual inspection costs: $280,000 for basic visual surveys
- Defect data inconsistent across sites and contractors
- No cell-level defect identification capability
