8.A. - Page 118 <br /> Exhibit B. Engineering and Construction Requirements <br /> • Ambient and back-of-module temperature (at least two (2) sensors for each, at different <br /> positions in the array) <br /> • Inverter status flags and general system status information <br /> • System availability <br /> • Site Load information. Available load data for the meter the system is connected to shall <br /> be collected by the solar monitoring solution as part of the DAS. <br /> Environmental data (temperatures and irradiance) shall be collected via an individual weather <br /> station installed for each site <br /> Data collected by the DAS shall be presented in an online web interface, accessible from any <br /> computer through the Internet with appropriate security(e.g., password controlled access). The <br /> user interface shall allow visualization of the data at least in the following increments: 15 <br /> minutes, hour, day, week, month, and year. The interface shall access data recorded in a server <br /> that may be stored on-site or remotely with unfettered access by the Buyer for the term of the <br /> Project. The online interface shall enable users to export all available data in Excel or ASCII <br /> comma-separated format for further analysis and data shall be downloadable in at least 15 <br /> minute intervals for daily, weekly, monthly and annual production. Historical data from the full <br /> lifetime of the PV system shall be available through the online interface. <br /> The monitoring system shall provide alerts when the system is not functioning within acceptable <br /> operating parameters. These parameters shall be defined during the design phase of the Project <br /> and specified in the DAS design document. <br /> Additionally, Seller shall make available, at no additional cost, the following: <br /> • Monthly Production report shall be available online to the Buyer personnel. <br /> • System performance data shall be made available electronically to the Buyer in a format <br /> and at a frequency to be determined during the Design Review process. <br /> • Additional reports shall be made available to the Buyer to assist the Buyer in reconciling <br /> system output with utility bills and the production guarantee,as determined in the Design <br /> Review process. <br /> • A Monitoring Manual shall be provided to the Buyer in printed or on-line form that <br /> describes how to use the monitoring system,including the export of data and the creation <br /> of custom reports. <br /> 3.5.20 FAA Requirements <br /> Seller shall be responsible to submit the appropriate FAA Form 7460-1, along with any other <br /> required forms and documentation, for all proposed PV systems within the approach or takeoff <br /> paths or on the property of airports as defined by the Code of Federal Regulations Title 14 Part <br /> 77.9. <br /> Exhibit B Page 18 <br />
