This schema is in support of the MTC's PTS (http://www.masstech-pts.org). Some basics before you begin. The schema is laid out to be sequence specific. There are choices to be made as to whether or not interval data will be provided. From there you are required to provide certain other supporting information while some supporting data is optional. Realize that providing certain optional data may mean other supporting data becomes required (ie; conditionally required). This is the node for providing monthly production data on a particular system. Note the attributes of sysID and sysType are required. So are the elements kwhRegistry and regDateTime. The regDateTime is of the format 2003-08-23T10:24:00 or YYYY-MM-DDTHH:MM:SS. This is based on a subset of XML and that format can be extended with timezone information but we require at least full date and time to the second. The serviceCostInDollars is optional since there is a default value associated in the PTS for each system. Any monthly change should be included and the reported value will overwrite the default. The field kwhRegistry is a value that comprises a current snapshot of the meter kWh reading at the time referenced by regDateTime. Based on the type of system referenced in this node, you will need to follow the group definitions below for what system type specific monthly production data needs to be added in to this node. Based on the type of system referenced in the parent node, you will need to follow the group definitions below for what system type specific interval production data needs to be added in to this node. Any of these element choices are extensions of the base type entryType. This is the base named type for all systems interval data. All fields are required except for system efficiency and average temperature. The field intervalRegistry is a value that comprises a current snapshot of the meter kWh reading at the time referenced by entryDateTime. The field entryDateTime takes the same format (and restrictions) as above. The field kwAcOutput is *NOT* the average kW being produced over the time from current interval -1 through current interval. Note that for certain types of systems there is other data being collected. See The documentation below for those. System efficiency is in the units fraction of 1 (percentage). This is the base named type for all systems interval data. All fields are required except for system efficiency and average temperature. The field intervalRegistry is a value that comprises a current snapshot of the meter kWh reading at the time referenced by entryDateTime. The field entryDateTime takes the same format (and restrictions) as above. The field kwAcOutput is *NOT* the average kW being produced over the time from current interval -1 through current interval. Note that for certain types of systems there is other data being collected. See The documentation below for those. This is the named group for all PV systems for their monthly data. There is currently only an empty element attached to this for the purposes of validating. Please ignore that and do not include the element emptyElement in your XML. These four elements extend the base entryType class to handle Photo Voltaic data. The fields are optional. Note that the current inclination and azimuth fields are only available from tracking PV. Average Irradiance is in Watts / Meter squared. Inclination and Azimuth is in degrees. This is the named group for all fuel cell systems for their monthly data. All fields are required and the field operatingHours needs to be a positive integer. The remaing are decimal format. Need units for cost and consumption. These elements extend the base entryType class to handle Fuel Cell data. The fields are optional. This is the named group for all Solar Thermal Electric systems for their monthly data. There is currently only an empty element attached to this for the purposes of validating. Please ignore that and do not include the element emptyElement in your XML. This is the named group for all Solar Thermal Electric systems for their interval data. There is currently only an empty element attached to this for the purposes of validating. Please ignore that and do not include the element emptyElement in your XML. This is the named group for all Advanced Biomass Power Conversion systems for their monthly data. There is currently only an empty element attached to this for the purposes of validating. Please ignore that and do not include the element emptyElement in your XML.
