4 Today s Session: BEST PRACTICES IN MANAGING SOLAR ASSETS Join Us for Part 2: HOW TO ASSESS & EXECUTE A PPA BUYOUT August AM Register at lgsec.org/events WEBINAR SERIES

5 THE WHY SOLAR ASSET MANAGEMENT

6 Properly managed systems perform better and last longer, yielding the maximum financial benefit THE WHY OF ASSET MANAGEMENT

7 Conversely, poorly managed systems will result in cost overruns, reduced performance, and decreased longevity THE WHY OF ASSET MANAGEMENT

8 BEST PRACTICES SOLAR ASSET MANAGEMENT

9 1. Performance Monitoring 2. Preventive Maintenance 3. Reactive Maintenance 4. Reporting & Forecasting FOUR MAJOR CONSIDERATIONS

10 PERFORMANCE MONITORING SOLAR ASSET MANAGEMENT

11 Daily reviews of prior day s performance with actual, expected, & weather adjusted data Daily review of open alerts Early detection of outages / underperformance Validate accuracy of metering and monitoring hardware / software Establish accurate baselines Insert Icon Here PERFORMANCE MONITORING

12 EXAMPLE Understanding Solar Monitoring Day 1 Day 2 Day 3 5% Soiling Loss, Cloudy Morning 5% Soiling Loss, Communication Interruption 5% Soiling Loss, Critical Outage

13 Daily reviews of prior day s performance with actual, expected, & weather adjusted data Daily review of open alerts Early detection of outages / underperformance is key Validate accuracy of metering and monitoring hardware / software Establish accurate baselines Insert Icon Here PERFORMANCE MONITORING

17 PREVENTIVE MAINTENANCE SOLAR ASSET MANAGEMENT

18 Create a documented facility operations plan Thoroughly inspect the systems annually Perform regular inverter maintenance as required by the manufacturer (important warranty condition) Insert Icon Here PREVENTIVE MAINTENANCE

19 Description of each system including: equipment & manufacturer lists, site plans, as-built drawings Contacts, roles and responsibilities Installer s Operations and Maintenance (O&M) guide Monitoring System Guide Emergency shutdown / restart procedures (contact list / location of keys) FACILITY OPERATIONS PLAN CONSIDERATIONS

20 Create a documented facility operations plan Thoroughly inspect the systems annually Perform regular inverter maintenance as required by the manufacturer (important warranty condition) Insert Icon Here PREVENTIVE MAINTENANCE

21 Visual inspection of panels, racking, inverters, balance of system components, point of interconnection Voc testing / I-V curve tracing Validate continuity and torque marks Verifying accuracy of meters & weather sensors ANNUAL INSPECTION CONSIDERATIONS
