It's almost one year since I installed my solar system and I couldn't be happier
For one thing I have not had an electric bill since installation. There was also a 30% tax credit that was very helpful
I was recently given a year to date analysis for my system
I. SYSTEM DETAILS
SMS ID: 184391
Module: (30) SPR-X22-360-D-AC
Year 1 Estimated Electricity Offset: 119.0%
Year 1 Target Production: 17,152 kWh
Energy Start Date: October 04, 2018
II. REVIEW SUMMARY
A. No performance modeling issue, the system is performing as expected:
Target Production (10.4.2018-7.6.2019) = 11,160.1 kWh
Actual Production (10.4.2018-7.6.2019) = 12,077.3 kWh
Lifetime Performance Index = 108.2%
B. Component check on 7/7/2019:
1. No active alert flag observed in SMS Partner UI.
2. All (30) microinverters are reporting.
3. Updated PVS5 Firmware version on 7/7/2019.
4. Consumption CT installed and configured correctly.
5. Turned on Production CT on 7/7/2019.
C. Evaluation of Maxfit Design and Actual Installation:
1. Maxfit Design - roof dimensions and site obstructions (chimney, trees, house next door) properly modeled in the Maxfit Design.
2. Module Layout - the number of modules per array matches the final EDDIE Layout but the module positioning is a bit off. The discrepancy is very minor and will not cause underproduction.
D. The system is expected to meet the Year 1 Target. Barring system failure and excessive soiling, the system is expected to produce ~6,700 kWh from July to Oct.
RECOMMENDATIONS:
1. The system is performing as expected and there is no active system failure. No action required for this site.
RECOMMENDED ACTION TO HO FOR OPTIMAL SYSTEM PERFORMANCE:
1. Keep all nearby trees/shrubs/hedges trimmed annually to ensure that the modules will receive as much sunlight as it did upon installation.
2. Wash the modules regularly (bi-monthly during dry season) to avoid performance issue due to soiling.
3. Maintain a functioning indoor internet connection and keep the SunPower Monitoring System connected to internet at all times for proper system monitoring.
