L'API Solar utilizza i dati sui luoghi per determinare il tipo di edificio e identifica
gli edifici in base alle immagini satellitari. Questa pagina descrive come determinare quali informazioni solari dell'edificio vengono restituite in una richiesta buildingInsights.
Tipi di edifici
L'API Solar supporta gli edifici di tipo
premise. Questo tipo
indica una posizione denominata, di solito un edificio o un insieme di edifici con un
nome comune.
Altri tipi, come
subpremise o
complessi, ad esempio edifici indipendenti situati in un'unica proprietà, a meno che
non siano registrati come premise,
non sono supportati.
Tetti degli edifici
L'API Solar identifica il posizionamento ottimale dei pannelli solari sul tetto in base alle
immagini satellitari. Gli edifici residenziali, in particolare i tetti inclinati, sono identificati con un alto grado di precisione, mentre gli edifici con tetti piani (ad esempio condomini o edifici commerciali) possono variare in precisione.
Se la risposta
buildingInsights non include il campo solarPanelConfigs, l'edificio è stato elaborato correttamente, ma non è stato possibile posizionare i pannelli sul tetto. Ciò può accadere se il tetto è troppo piccolo per posizionare i pannelli o troppo ombreggiato per consentire ai pannelli di generare energia significativa.
Utilizza place_id per fare riferimento al luogo corrispondente.
Utilizza le coordinate di latitudine e longitudine del luogo nella richiesta dell'API Solar
buildingInsights.
Se l'API Solar trova un edificio corrispondente, verifica che il
place_id nella risposta buildingInsights corrisponda al place_id
dell'API Geocoding o dell'API Place Autocomplete.
Per limitare i risultati ai luoghi di tipo premise, aggiungi un filtro per il tipo di luogo
alle risposte dell'API Geocoding o dell'API Places.
Puoi anche offrire un'esperienza complementare consentendo agli utenti di selezionare l'edificio sulla mappa utilizzando l'API Maps JavaScript. Estrai la latitudine e la longitudine dell'edificio dall'evento
mouse, quindi passa queste coordinate in una
richiesta buildingInsights.

It primarily supports `premise` type buildings, excluding `subpremise` types. Optimal solar panel placement is assessed, with higher accuracy for residential pitched roofs; flat roofs may vary. The API can be used by converting an address to coordinates via the Geocoding or Place Autocomplete APIs, or by using a location selected on a map. The results can be filtered to places of type premise, and the results from the building insights api can be compared to the results from the geocoding or places API.\n"],null,["# Search buildings\n\nThe Solar API uses place data to determine building type and identifies\nbuildings based on satellite imagery. This page describes how to determine which\nbuilding's solar information is returned in a\n[`buildingInsights`](/maps/documentation/solar/reference/rest/v1/buildingInsights)\nrequest.\n\nBuilding types\n--------------\n\nThe Solar API supports buildings of type\n[`premise`](/maps/documentation/places/web-service/place-types). This type\nindicates a named location, usually a building or collection of buildings with a\ncommon name.\n\nOther types, such as\n[`subpremise`](/maps/documentation/places/web-service/place-types#table-b) or\ncompounds --- for example, detached buildings located on a single property, unless\nregistered as a [`premise`](/maps/documentation/places/web-service/place-types) ---\nare **not** supported.\n\nBuilding roofs\n--------------\n\nThe Solar API identifies optimal rooftop solar panel placement based on\nsatellite imagery. Residential buildings, particularly inclined or pitched\nroofs, are identified with a high degree of accuracy, while buildings with flat\nroofs (for example, apartment or commercial buildings) may vary in accuracy.\n\nIf the\n[`buildingInsights`](/maps/documentation/solar/building-insights#example_response_object) response does not include the field `solarPanelConfigs`, the building was processed correctly, but we were unable to put panels on the roof. This may happen if the roof is too small to place panels or too shaded for panels to generate significant energy.\n| **Tip:** Based on other selection approaches, including manual user selection or a custom programmatical selection, you can use the Solar API [`dataLayers`](/maps/documentation/solar/reference/rest/v1/dataLayers) endpoint to create your own solar potential calculations and panel placement.\n\nSearching from an address\n-------------------------\n\n1. You can convert an address to latitude and longitude coordinates using the\n [Geocoding API](/maps/documentation/geocoding/requests-geocoding#Types) or\n [Place Autocomplete API](/maps/documentation/places/web-service/autocomplete).\n\n Use the `place_id` to refer to the matched place.\n2. Use the place latitude and longitude coordinates in your Solar API\n [`buildingInsights`](/maps/documentation/solar/reference/rest/v1/buildingInsights)\n request.\n\n - If the Solar API finds a matching building, check that the `place_id` in the `buildingInsights` response matches the `place_id` from the Geocoding API or the Place Autocomplete API.\n - To limit results to places with type `premise`, add a place type filter to Geocoding API or Places API responses. \n\n ```json\n {\n \"name\": \"buildings/ChIJh0CMPQW7j4ARLrRiVvmg6Vs\",\n \"center\": {\n \"latitude\": 37.4449739,\n \"longitude\": -122.13914659999998\n },...\n }\n ```\n\n| **Note:** Sometimes the place IDs will not match, which means the searched (lat, lng) does not resolve to the same address or building. Even if the [Geocoding\n| API](/maps/documentation/geocoding/overview) response is of granularity [`ROOFTOP`](/maps/documentation/geocoding/requests-geocoding#results), the `place_id` may have a type other than `premise`.\n\nYou can use the [open source sample\napp](https://solar-potential-296769475687.us-central1.run.app/) or make a\n[`buildingInsights`](/maps/documentation/solar/building-insights) request to\ncheck the `place_id` for buildings covered by the Solar API.\n\nSelecting a location on a map\n-----------------------------\n\nYou can also offer a complementary experience by enabling users to select the\nbuilding on the map using the [Maps JavaScript\nAPI](/maps/documentation/javascript/overview). Extract the building's latitude\nand longitude from the [mouse\nevent](/maps/documentation/javascript/examples/event-click-latlng), then pass in\nthose coordinates in a\n[`buildingInsights`](/maps/documentation/solar/building-insights) request."]]
