Table G2: ECM 1: Solar PV Category. • Conservation Ground Mount Solar PV system Measure M&V Plan Option B (all parameter measurement) will be used to quantify the energy savings Description associated with the Solar Photovoltaic system. Baseline The Solar PV system has been modeled utilizing software to determine the expected Performance production for the project location based on system design characteristics and Parameters historical average solar availability. Post Installation The new Solar PV system will be monitored during start-up / commissioning to Performance confirm that the system is operating properly, and that the overall system is operating Parameters as intended. The post installation performance parameters include the following parameters: • Total system kWh production • Site Insolation solar availability • System availability These parameters will be monitored using 15-minute interval data from the installed Data Acquisition System after installation is completed to verify the installed system is producing electricity consistent with the modeled expected output values including the expected 0.5% annual degradation of PV panel production. If actual production exceeds the guaranteed production, no adjustments will be made. If actual production is less than the guaranteed production, monthly adjustments may be made to account for less than expected insolation, system outages, or other factors that are not within the control of Ameresco. A regression model will be built using actual performance data to show the production achieved for a given unit of solar availability (insolation). This regression will be used to determine the impact of any equipment downtime, and it will also be used to determine any potential adjustments for insolation lower than the monthly average for the site. Performance Confirm that the system produces the expected annual kWh output as adjusted as Assurance described above. Analysis will be performed using values extracted from the DAS Activities and reported annually during the M&V term. Assurance Ameresco Activities Performed By Customer Provide all required maintenance and ensure system is allowed to operate Responsibilities Performance The year beginning the first day of the month following Delivery and Acceptance. If Period additional years of M&V are paid for, the performance period will be each subsequent year beginning on the first day of the month following the anniversary Delivery and Acceptance.
