Solar & Storage Performance Validation | Owner's Engineering
On new construction, our ASTM & Capacity test are needed to achieve final completion. For clients acquiring existing assets in operation, our historical analysis and future projections are essential for accurate asset valuation. We are experts at gathering performance data, filtering it, and performing a wide array of analysis.

Our performance reporting areas of expertise include:
- ASTM Capacity Tests
- Performance Ratios
- Climate adjusted Actual Vs. Expected
- Annual performance guarantee calculations
- Monthly, Quarterly, and Annual performance reports
- Configuration & troubleshooting of monitoring systems and weather sensors
