|---|---|
| defined in | http://solargis.info/schema/ws-data.xsd |
| description | The root element of the XML request is the <dataDeliveryRequest> with required attributes 'dateFrom' and 'dateTo' for setting desired data period in the response. Accepted is a date string in the form of ''YYYY-mm-dd" e.g., "2017-09-30". It is assumed UTC (GMT+00) time zone for both dates unless otherwise specified by the <timeZone> element of the <processing>. |

| @dateFrom* | start of the data period, ''YYYY-mm-dd" |
| @dateTo* | end of the data period, ''YYYY-mm-dd" |
Explanation of the table above: The element name is that what you can see in the XML request. If the element is of simple type, the content is a literal (text or number), otherwise the content can be list of another <element> or none. Attribute of the element is prefixed by '@' character. Required attribute is marked by '*' character.

| description | Parametrization of PV system mounting type used for calculating GTI and PVOUT. If this element is missing and GTI/PVOUT is requested, flat-lying PV panels are considered (GTI=GHI). Examples: <pv:geometry xsi:type="pv:GeometryFixedOneAngle" azimuth="180" tilt="25"/> <pv:geometry xsi:type="pv:GeometryOneAxisHorizontalNS" rotationLimitEast="-90" rotationLimitWest="90" backTracking="true"/> <pv:geometry xsi:type="pv:GeometryOneAxisInclinedNS" axisTilt="30" rotationLimitEast="-90" rotationLimitWest="90" backTracking="true"/> <pv:geometry xsi:type="pv:GeometryOneAxisVertical" tilt="25" rotationLimitEast="-180" rotationLimitWest="180" backTracking="true"/> <pv:geometry xsi:type="pv:GeometryTwoAxisAstronomical" rotationLimitEast="-180" rotationLimitWest="180" tiltLimitMin="10" tiltLimitMax="60" backTracking="true"/> |
| content | none |
| @type* | required, concrete type of given geometry. Use one from GeometryFixedOneAngle, GeometryOneAxisHorizontalNS, GeometryOneAxisInclinedNS, GeometryOneAxisVertical, GeometryTwoAxisAstronomical, see table below |
| @azimuth | orientation of tilted panel surface in degrees, defined as true geographical azimuth (0:north, 90:east, 180:south, 270:west, 360:north), default is 180 deg., the attribute is not defined for a horizontal surface, required only for 'GeometryFixedOneAngle' type |
| @tilt | tilt of panel surface in degrees range (0, 90), 0=horizontal, 90=vertical surface, required for 'GeometryFixedOneAngle' and 'GeometryOneAxisVertical' types |
| @axisTilt | optional, tilt of rotating inclined axis in degrees, 0 = horizontal, 90 = vertical axis, only considered for 'GeometryOneAxisInclinedNS', WARNING: if this attribute is missing, the value defaults to 30 degree. |
| @rotationLimitEast | optional, default is the unlimited motion in the range (-180, 180), used for all trackers. The general rule is: negative value is used for the east side, positive for the west side, the same rule applies for both hemispheres). The meaning is slightly different for different type of trackers: GeometryOneAxisHorizontalNS: rotation limits are defined as tilt of tracker table relative to its central position (which is horizontal=0 deg.), both limits are typically symmetric, e.g., rotationLimitEast=-50, rotationLimitWest=50 GeometryOneAxisInclinedNS: rotation limits are defined as tilt of tracker table relative to its central position (in this case the inclined plane defined by axisTilt attribute), both limits are typically symmetric, e.g., rotationLimitEast=-50, rotationLimitWest=50 GeometryOneAxisVertical: rotation limits are defined relative to 0 deg. (initial tracker position regardless of hemisphere), default range from -180 to 180 deg (-90 deg. east and +90 deg. west) GeometryTwoAxisAstronomical: definition (for vertical axis) is the same as with GeometryOneAxisVertical tracker |
| @rotationLimitWest | optional, westing motion limit, described above |
| @tiltLimitMin | optional, only used with the horizontal axis of 'GeometryTwoAxisAstronomical' tracker. Limit is defined in the range of degrees (-90, +90), relative to the horizontal position of the tracking surface (0 deg.). Example: tiltLimitMin="0" tiltLimitMax="60", the tracker follows the sun elevation in the range from horizontal position to 60 degree of tilt. |
| @tiltLimitMax | optional, max tilt of the tracking surface, described above |
| @backTracking | optional boolean value, default is 'false' - tracker moves freely regardless of the neighbors, value 'true' - tracker moves in the way it avoids shading from neighboring tracker constructions. |
