Overview of Solargis API

The purpose of the Solargis API is to provide automated access to Solargis data and services for computers over the web. API is the "user interface" for developers. Developers can automate integrating Solargis products into customized solutions.

Table: overview of data available through the Solargis API.

Solargis web services consist of two different endpoints:

Data Delivery Web Service - the main service for accessing Solargis time series data. Both request and response is an XML document. The request parameters (XML elements and attributes) are formally described by XML Schema Definition documents (XSD). By using the schema, request or response can be verified programmatically. For this service, we provide two endpoints - the REST-like endpoint, and the SOAP endpoint. Look for more technical information here. Authentication and billing is based on API key registered with the user. Please contact us to discuss details, set up trial or ask for a quotation.
LTA Web Service - this simple web service provides monthly long-term averaged data (including yearly value) of PV, solar and meteorological data with global coverage. The service is aimed for prospection and pre-feasibility. By sending an XML request the user mimics the click on the Calculate button in the interactive Solargis Prospect application. Request and response for the service is not described in this user guide. More information can be found here.

Additionally, we provide the Push data delivery service where the request (a CSV file) is stored in the user's remote directory (SFTP, Azure,...). The service is then scheduled to push CSV response files regularly. Request processing is asynchronous - the client uploads the CSV request, the server processes the request according to a schedule (e.g., once a day, every hour), the client then checks for the response files. The CSV request allows for multiple locations in one file. For pricing and setting up a trial FTP user account, please contact us.

In the case of the solar and PV time series, we use satellite data since available history up to the present moment plus nowcasting for additional 5 hours ahead. The range of the satellite data includes historical / archived data, operational data, real-time data and the Cloud Motion Vector model (CMV, also called as nowcasting). Historical data ranges up to the last completed calendar month and can be considered as "definitive". Data in the current calendar month up to DAY-1 is so-called "operational", and will be re-analyzed in the beginning of the next month using the final version of required data inputs. Important is to note that differences introduced with the re-analysis are typically small. Solar data in the current day comes from the "real-time" satellite data and will be updated as soon as the current day is finished. Then, based on the latest satellite images, we predict solar data parameters by using the CMV model in the range of next 5 hours. The present moment and a short period before is covered by the nowcasting data as the very recent satellite scene is still in progress. This delay can take up to 30 minutes (depending on the satellite scanning frequency). Later on, after the nowcasting time range, we use post-processed output from Numerical Weather Prediction models (NWP). Satellite-based data is seamlessly integrated with the NWP data within the response. In the case of locations where satellite real-time & nowcasting data is not yet available, the NWP data is used over the course of the current day. All meteorological data (TEMP, WS, AP, RH,...) comes from the NWP data sources.

The schema shows how the data sources are integrated into the response.

Satellite based solar data

Current spatial coverage of satellite data available through the API.

In the orange regions the satellite data is updated every day (so that DAY-1 is available, see below table for the exact timing). Regions outlined by the dark red polygons are updated every few minutes (satellite based real-time and nowcasting data are available in the current day). Main data parameters include GHI, DNI, DIF (main calculated parameters are GTI and PVOUT).

Map of satellite data regions.

METEOSAT PRIME	1994-01-01	2005+: MSG 15-minute time step 2004 - 1994: MFG, 30-minute time step	00:30 UTC	Satellite data availability delay is 2-16 minutes and it increases from north to south. Processing frequency is every 15 minutes and it takes another 5-15 minutes.
METEOSAT IODC	1999-01-01	2017+: MSG 15-minute time step 2016 - 1999: MFG, 30-minute time step	22:30 UTC	same as the METEOSAT PRIME region
IODC-HIMAWARI	1999-01-01	2017+: HIMAWARI 10-minute time step 2016 - 1999: MFG, 30-minute time step	16:00 UTC	same as the HIMAWARI region
HIMAWARI	2006-07-01	2016+: HIMAWARI 10-minute time step 2015 - 2006: MTSAT, 30-minute time step	16:00 UTC	Satellite data availability delay is 5-15 minutes and it increases from south to north. Processing frequency is every 10 minutes and it takes another 5-15 minutes.

Each daily update of the data re-calculates satellite values for two days backward (DAY-1 and DAY-2). Monthly update (on the 3rd day of each calendar month) re-calculates the whole previous month as soon as completed. The purpose of these updates is described in this article. We gradually expand spatial coverage of the satellite data accessible via API - towards the global coverage. To request operational and historical data in the out-of-coverage areas, please use Solargis climData online shop or contact us.

The data from orange regions in the map is also available by using interactive application pvSpot (daily operational data) and the data is accessible within minutes after purchasing in the climData online shop.

Nowcast data availability and delay

Total delay of the near real-time data is a combination of satellite data availability delay, data processing delay and the user request delay (after processing is finished).

Primary satellite data availability delay after actual scanning of a location depends on its latitude and satellite region as follows:

PRIME, IODC - delay is 2-16 minutes (increases from north to south)
HIMAWARI - delay is 5-15 minutes (increases from south to north)
GOES-EAST & WEST - delay is 2-12 minutes (increases from south to north)

Data processing delay (including retrieval, preprocessing and nowcast model run) takes 5-15 min. Data is available immediately after the data processing is finished.
Processing frequency is 10 minutes (HIMAWARI, GOES-EAST & WEST) or 15 minutes (PRIME, IODC), i.e. after each new satellite image. This also determines the window when any given nowcast run is available for delivery, before it is replaced by the next run. The timing of a customer's request after the start of this interval represents the user request delay, which is thus in the range 0-10 or 0-15 minutes.

Numerical Weather Prediction (NWP) data

Solar data parameters (GHI, DNI) taken from NWP models are used to fill period from the current day onward. NWP data are not used for historical solar data records (see the satellite data section). For meteorological data parameters (TEMP, WS, WD, PREC, RH, PWAT, ...) NWP data sources are used in the whole range. Historical meteorological data older than MONTH-1 can be considered as definitive. Solargis uses post-processed NWP historical data products from the following providers: NOAA (GFS, CFS v2), ECMWF (IFS, ERA5), DWD (ICON). The NWP data coverage is global - between latitudes -60 deg (South) and 70 deg (North).

Data Delivery Web Service

The client (most often a computer) will send the XML request and waits for the XML response. Users can test web services directly from the web browser by using e.g. REST Client for Firefox or via a native application like Postman. Before sending requests user must set the HTTP Method to "POST", define endpoint URL to https://solargis.info/ws/rest/datadelivery/request?key=demo and also set a header to "Content-Type: application/xml". Then use the XML request examples below and send them in the body of the HTTP request and explore XML responses. Typically, developers will create client code to send requests and handle responses scheduled in time. For creating client code, we provide samples for Python, Java, PHP. For all technical details visit this link.

Units of solar and PV data parameters

For sub-hourly data the solar and PVOUT value typically represents instantaneous value (a power measured exactly at the given timestamp), so the PVOUT unit will be the kW (or W/m2 in case of solar irradiance).

For hourly and bigger aggregation, the value represents the amount of energy accumulated or averaged within the agg. interval - the unit is the kWh (or Wh/m2, kWh/m2 in case of solar irradiation).

content	none
@type*	required, type of the mounting geometry. Use one from GeometryFixedOneAngle, GeometryOneAxisHorizontalNS, GeometryOneAxisInclinedNS, GeometryOneAxisVertical, GeometryTwoAxisAstronomical, see table below for pictures.
@azimuth	the value in degrees of a true geographical azimuth (0: north, 90: east, 180: south, 270: west, 360: north --> a compass value) . In the case of 'GeometryFixedOneAngle' the azimuth attribute is required. In the case of two tracker types (GeometryOneAxisHorizontalNS, GeometryOneAxisInclinedNS) the value is the compass value at which the southern end of the tracker axis is oriented. Regardless of the Earth's hemisphere. With trackers, the value is limited to the range from 135 deg. to 225 deg. inclusive, so the deviation from the north-south line is not bigger than 45 degrees. With trackers, the attribute is optional and it defaults to 180 deg. (which means the southern end of the axis faces to geographical south, so the tracker field is aligned with the north-south line which is the optimal solution for most cases).
@tilt	tilt of panel surface in degrees range (0, 90), 0=horizontal, 90=vertical surface, required for 'GeometryFixedOneAngle' and 'GeometryOneAxisVertical' types
@axisTilt	optional, default is 30 deg., allowed range is (0, 90). Tilt of rotating inclined axis in degrees, 0 = horizontal, 90 = vertical axis, only applicable for 'GeometryOneAxisInclinedNS', WARNING: if this attribute is missing, the value defaults to 30 degree.
@rotationLimitEast	optional, for trackers only default values / allowed ranges: default is -180 deg, allowed range: -180, 180. Applies for vertical axis of GeometryTwoAxisAstronomical and GeometryOneAxisVertical trackers. Rotation limits are in this case defined relative to 0 deg. (initial tracker position regardless of the hemisphere), default range from -180 to 180 deg (e.g., -90 deg. for east and +90 deg. for west) default is -90, allowed range: -90, 90, Applies for the GeometryOneAxisHorizontalNS and GeometryOneAxisInclinedNS. Rotation limits are in this case defined as tilt of tracker table relative to its central position, both limits are typically symmetric e.g., rotationLimitEast=-50, rotationLimitWest=50 The general rule is: negative values are used for the east side, positive for the west side, the same rule applies for both Earth hemispheres). The value of rotationLimitEast must be smaller or equal than the rotationLimitWest.
@rotationLimitWest	optional, for trackers only default values / allowed ranges: default is 180 deg, allowed range: -180, 180. Applies for vertical axis of GeometryTwoAxisAstronomical and GeometryOneAxisVertical trackers. Rotation limits are in this case defined relative to 0 deg. (initial tracker position regardless of the hemisphere), default range from -180 to 180 deg (e.g., -90 deg. for east and +90 deg. for west) default is 90, allowed range: -90, 90, Applies for the GeometryOneAxisHorizontalNS and GeometryOneAxisInclinedNS. Rotation limits are in this case defined as tilt of tracker table relative to its central position, both limits are typically symmetric e.g., rotationLimitEast=-50, rotationLimitWest=50 The general rule is: negative values are used for the east side, positive for the west side, the same rule applies for both Earth hemispheres). The value of rotationLimitEast must be smaller or equal than the rotationLimitWest.
@tiltLimitMin	optional, for trackers only Default is 0 deg, allowed range: 0, 90. Used with the horizontal axis of GeometryTwoAxisAstronomical tracker. Limit is defined relative to the horizontal position of the tracking surface (0 deg.). Example: if set as tiltLimitMin="0" and tiltLimitMax="60" - the tracker follows the sun elevation in the range from horizontal position to 60 degree of tilt. The value of tiltLimitMin must be smaller or equal than the tiltLimitMax.
@tiltLimitMax	optional, for trackers only Default is 90 deg, allowed range: 0, 90. Used with the horizontal axis of GeometryTwoAxisAstronomical tracker. Limit is defined relative to the horizontal position of the tracking surface (0 deg.). Example: if set as tiltLimitMin="0" and tiltLimitMax="60" - the tracker follows the sun elevation in the range from horizontal position to 60 degree of tilt. The value of tiltLimitMin must be smaller or equal than the tiltLimitMax.
@backTracking	optional boolean value, default is 'false' - tracker moves freely regardless of the neighbors, value is 'true' - tracker moves in the way that it avoids shading from neighboring tracker constructions.

PV system

element name	system
defined in	http://solargis.info/schema/common-pv.xsd
description	Parametrization of the PV system. Required for simulating PVOUT parameter.
content	required one <module> element, required one <inverter> element, required one <losses> element, optional one <topology> element,
@installedPower*	required float value (greater than zero). Total installed DC power of the PV system in kilowatts-peak (kWp). The total PV system rating consists of a summation of the panel ratings measured in STC.
@installationType	optional, use one from FREE_STANDING (default), ROOF_MOUNTED, BUILDING_INTEGRATED. This property of the PV system helps to estimate how modules are cooled by air. For sloped roof with PV modules on rails tilted at the same angle as the roof choose 'ROOF_MOUNTED' value. For PV modules incorporated into building facade choose 'BUILDING_INTEGRATED' value. This option is considered as the worst ventilated. As the best ventilated option is considered 'FREE_STANDING' installation. This typically means stand-alone installation on tilted racks anchored into the ground. Also choose this option if a PV system is installed on a flat roof.
@dateStartup	optional string formatted as "yyyy-mm-dd" (example 2015-01-01). Start-up date of the PV system (unpacking of modules). This parameter is used for calculation of degradation of modules caused by aging. If omitted, the degradation is not taken into account.
@selfShading	optional, default is 'false'. The parameter affects PV power calculation for 'GeometryFixedOneAngle' geometry, then 'GeometryOneAxisInclinedNS' and 'GeometryOneAxisHorizontalNS' trackers if backTracking="false". When 'selfShading' is switched on, the simulated PV power is typically lower comparing to standalone PV construction not affected by shading from its neighbors. With trackers, always switch off 'backTracking' attribute, because the back tracking avoids self-shading.

The value is given by manufacturer and for ventilated free-standing PV systems only. If the element is missing, the NOCT value defaults to (based on technology): CSI=46°C ASI=44°C CDTE=45°C CIS=47°C
content	required, float number in degrees Celsius

element name	PmaxCoeff
defined in	http://solargis.info/schema/common-pv.xsd
description	Negative percent float value representing the change of PV panel output power for temperatures other than 25°C (decrease of output power with raising temperature). This property is given at the STC by manufacturer. If the element is missing, the PmaxCoeff value defaults to (based on technology): CSI=-0.438%/°C ASI=-0.18%/°C CDTE=-0.297%/°C CIS=-0.36%/°C
content	required, float number, percent per degree Celsius (%/°C)

element name	inverter
defined in	http://solargis.info/schema/common-pv.xsd
description	Parametrization of the PV system inverter. Required for simulating PVOUT parameter. All inverters in one PV system are considered of the same type.
content	optional one <efficiency> element, optional one <limitationACPower> element

element name	efficiency
defined in	http://solargis.info/schema/common-pv.xsd
description	Efficiency of the inverter. If the element is missing, the efficiency is given as a constant value of 97.5%.
@type*	required, concrete type of how efficiency of the inverter should be modeled. Use one from EfficiencyConstant, EfficiencyCurve
content	required, based on type: EfficiencyConstant: float number, [%]. Value of inverter's efficency known as Euro or CEC (California Energy Commission) efficiency. This value is a calculated weighted efficiency given by manufacturer. It gives a simplified picture about an inverter's, in fact non-linear, performance. Valid range of this value is typically in the range 70%-100%. For better results, it is recommended to provide inverter's efficiency curve. EfficiencyCurve: text value, pairs of kW:percent. Efficiency of inverter is of non-linear nature, so it can be described as simplified curve defined as list of data points. Data point on the curve is defined by coordinates, where the x coordinate is absolute float value of input power in kilowatts (kW) and y coordinate is percent float value of the corresponding inverter's efficiency (%). This parameter accepts string value of this pattern: 'x1:y1 x2:y2 x3:y3 xn:yn'. A dot should be used as decimal separator, white space as a pair delimiter and colon as x:y delimiter. We assume the last point determines the maximum input power of the inverter (with corresponding efficiency). Example of an efficiency curve with the maximum input power of 3 kW is: <pv:efficiency xsi:type="pv:EfficiencyCurve" dataPairs="0:85.6 0.5:96.2 1:98 1.5:97 2:97 2.5:96 3.0:96"/> It is assumed, that one efficiency curve is valid for all inverters of the PV system (their powers are summed).

description	Maximum power accepted by the inverter as AC output. Higher power values are 'clipped'. Clipping refers to the situation where the AC power output of an inverter is limited due to the peak rating of the inverter (the parameter value in kW), even though the additional power may still be available from the solar modules. If you have power factor (PF) and AC limit in kVA available, use this formula: PF * AC_limit_kVA = kW, to obtain the value of this parameter. No default.
content	required, float number, kilowatts [kW]

element name	losses
defined in	http://solargis.info/schema/common-pv.xsd
description	Estimation of various PV losses.
content	optional one <acLosses> element, optional one <dcLosses> element

element name	dcLosses
defined in	http://solargis.info/schema/common-pv.xsd
description	Estimation of power losses on the DC side. If the element is missing, the specific DC losses are estimated by default as: snowPolution: 2.5% cables: 2.0% mismatch: 1.0%
content	none
@snowPollution	annual value of estimated dirt and snow losses [%]
@monthlySnowPollution	Distribution of the 'snowPollution' attribute value into 12 monthly average values. Value of the parameter must consist of 12 percent float values delimited by white space. If this parameter is present, it takes precedence over 'snowPollution' attribute. Example: <pv:dcLosses cables="0.2" mismatch="0.3" monthlySnowPollution="5 5.2 3 1 1 1 1 1 1 1 2 4"/>
@cables	annual value of estimated DC cabling losses [%]
@mismatch	annual value of estimated DC mismatch losses [%]

element name	acLosses
defined in	http://solargis.info/schema/common-pv.xsd
description	Estimation of power losses on the AC side. If the element is missing, the specific AC losses are estimated by default as: transformer: 1.0% cables: 0.5%
content	none
@transformer	annual value of estimated transformer losses [%]
@cables	annual value of estimated AC cabling losses [%]

element name	topology
defined in	http://solargis.info/schema/common-pv.xsd
description	The element is for defining PV plant layout on the ground. The reason is to provide inputs for calculation of self-shading impact on PV power (e.g., how close to each other are PV constructions).
content	none
@type*	XML element type, required, concrete type of how topology should be modeled. Use one from TopologyRow (applies for the 'GeometryFixedOneAngle' geometry), TopologyColumn (use for all trackers). It is assumed trackers are spaced equally in both directions (rows and columns) creating a regular grid.
@relativeSpacing	required, unitless ratio. The attribute specifies the ratio of distance between the neighboring PV table legs and PV table width. Direction of the distance depends on whether topology is specified as TopologyRow or TopologyColumn. See picture below how to calculate the value.
@type	optional. This parameter estimates a magnitude of loss of PV power when modules are shaded or semi-shaded. The effect depends on wiring interconnections within a module. Shading influence ranges from 0% (no influence) to 100% (full influence) and it is classified into following categories (based on the influence value): PROPORTIONAL = 20% (for a-Si, CdTe and CIS where the loss of generated electricity is proportional to the size of module area in shade) UNPROPORTIONAL1 = 40% (for c-Si with proper layout optimization if the stings are connected independently in array) UNPROPORTIONAL2 = 60% (for c-Si modules with intermediate layout optimization if strings are interconnected within the array) UNPROPORTIONAL3 = 80% (for c-Si, modules are portrait-oriented with poor layout optimization, bottom cells in shade will shut the whole row of modules down) When this attribute is missing, the self-shading influence is estimated to 5%.

Figure: Calculation of relative row spacing value (= x3/x2).

For sub-hourly data the PVOUT value typically represents instantaneous value (a power measured exactly at the given timestamp), so the PVOUT unit will be the kW (or W/m2 in case of irradiation).

For hourly and bigger aggregation, the value represents an energy accumulated or averaged within the agg. interval - the unit is the kWh (or Wh/m2, kWh/m2 in case of irradiation).

XML response

The root element of the XML response is the <dataDeliveryResponse> containing one <site> element inside. The <site> element has the 'id' attribute referencing the site in the request. The <site> consists of <metadata> section, one <columns> element and multiple <row> items. The <row> holds timestamp information in the 'dateTime' attribute and the numeric values in space-separated text value of the 'values' attribute. Values are sorted in the same order as their labels in the <columns> element.

Timestamps used in the XML response comply with the ISO 8601 standard for date and time representation https://en.wikipedia.org/wiki/ISO_8601. Time stamps are also aware of time zone (offset from UTC). Time zone designators are appended after the the time part of timestamp string. If the time is in UTC (https://en.wikipedia.org/wiki/Coordinated_Universal_Time), Z is added directly after the time without a space. Z is the zone designator for the zero UTC offset e.g., 2017-09-22T01:00:00.000Z . If there is an offset from UTC, this is designated by appending +/-HH:MM after the timestamp string, e.g., 2017-09-22T01:00:00.000-05:00 (UTC-5).

Push data delivery

CSV request examples

Push delivery request is stored on a user's remote directory. Data request file must have header with input parameter names on a first row. Below header, there can be unlimited number of rows with parameter values (each row is treated as one request). Order of parameters in the header is optional. CSV request for the Push contract delivery is typically prepared, maintained and validated by Solargis.

Example of regular CSV request for monitoring

Note, there are no "fromDate" and "toDate" parameters. Date period is resolved according to contract and managed by the scheduled automated process.
