Membuat permintaan insight build

Developer Wilayah Ekonomi Eropa (EEA)

Endpoint buildingInsights memberikan insight tentang lokasi, dimensi, dan potensi tenaga surya sebuah bangunan. Secara khusus, Anda bisa mendapatkan informasi tentang:

Potensi tenaga surya, termasuk ukuran panel surya, jumlah sinar matahari tahunan, faktor offset karbon, dan lainnya
Posisi, orientasi, dan produksi energi panel surya
Estimasi tagihan energi bulanan tata letak panel surya yang optimal serta biaya dan manfaat terkait

Untuk mempelajari lebih lanjut cara Solar API menentukan potensi tenaga surya dan tingkat kecerahan, lihat Konsep Solar API.

APIs Explorer memungkinkan Anda membuat permintaan langsung sehingga Anda dapat memahami API dan opsi API:

Tentang permintaan insight bangunan

Untuk meminta insight bangunan, kirim permintaan HTTP GET ke:

https://solar.googleapis.com/v1/buildingInsights:findClosest?key=YOUR_API_KEY

Sertakan parameter URL permintaan yang menentukan koordinat garis lintang dan garis bujur lokasi serta tingkat kualitas minimum yang diperlukan dan diizinkan dalam hasil.

Tentang respons insight bangunan

Solar API menampilkan informasi tentang lokasi, dimensi, dan potensi tenaga surya sebuah bangunan di isi respons.

Kualitas citra

Dalam beberapa kasus, kualitas citra yang diminta di lokasi tertentu mungkin berbeda dengan kualitas citra yang tersedia. Dalam skenario tersebut, perilaku berikut diharapkan:

Skenario	Perilaku respons
Lokasi tidak memiliki citra yang memenuhi `requiredQuality`.	Solar API menampilkan error `NOT_FOUND` dengan kode status 404.
Permintaan menentukan `requiredQuality` tertentu, tetapi hanya data dengan tingkat kualitas citra yang lebih tinggi yang tersedia.	Solar API menampilkan data kualitas tertinggi yang tersedia di lokasi tersebut.

Contoh permintaan insight bangunan

Contoh berikut meminta informasi insight bangunan untuk lokasi dengan koordinat garis lintang = 37.4450 dan garis bujur = -122.1390:

Kunci API

Untuk membuat permintaan menggunakan kunci API, sertakan kunci API Anda sebagai parameter input:

curl -X GET "https://solar.googleapis.com/v1/buildingInsights:findClosest?location.latitude=37.4450&location.longitude=-122.1390&requiredQuality=HIGH&key=YOUR_API_KEY"

Anda juga dapat membuat permintaan HTTP dengan menempelkan URL dalam permintaan cURL ke kolom URL browser.

Token OAuth

Catatan: Format ini hanya untuk lingkungan pengujian. Untuk mengetahui informasi selengkapnya, lihat Menggunakan OAuth.

Untuk membuat permintaan menggunakan OAuth, teruskan nama project penagihan dan token OAuth Anda:

curl -H "Authorization: Bearer $(gcloud auth print-access-token)" \
  -H "X-Goog-User-Project: PROJECT_NUMBER_OR_ID" \
  "https://solar.googleapis.com/v1/buildingInsights:findClosest?location.latitude=37.4450&location.longitude=-122.1390"

TypeScript

Untuk membuat permintaan menggunakan TypeScript, sertakan kunci API atau token OAuth Anda dalam permintaan. Contoh berikut menggunakan kunci API:

/**
 * Fetches the building insights information from the Solar API.
 *   https://developers.google.com/maps/documentation/solar/building-insights
 *
 * @param  {LatLng} location      Point of interest as latitude longitude.

            "latitude": 37.444982,
            "longitude": -122.1387809
          }
        },
        "planeHeightAtCenterMeters": 10.67585
      },
      /.../
    ],

Berdasarkan karakteristik ini, Anda dapat memilih untuk hanya memilih panel yang ditempatkan di segmen atap tertentu. Setiap panel yang ditampilkan melalui endpoint buildingInsights menyertakan nilai segmentIndex yang menunjukkan segmen atap tempat panel ditempatkan:

{
        "panelsCount": 142,
        "yearlyEnergyDcKwh": 101170.17,
        "roofSegmentSummaries": [
          {
            "pitchDegrees": 12.273684,
            "azimuthDegrees": 179.12555,
            "panelsCount": 122,
            "yearlyEnergyDcKwh": 87260.48,
            "segmentIndex": 1
          },
          {
            "pitchDegrees": 11.245564,
            "azimuthDegrees": 179.204,
            "panelsCount": 18,
            "yearlyEnergyDcKwh": 12544.052,
            "segmentIndex": 3
          },
          {
            "pitchDegrees": 2.5699794,
            "azimuthDegrees": 86.05642,
            "panelsCount": 1,
            "yearlyEnergyDcKwh": 681.69183,
            "segmentIndex": 10
          },
          {
            "pitchDegrees": 0.10844088,
            "azimuthDegrees": 0,
            "panelsCount": 1,
            "yearlyEnergyDcKwh": 683.9312,
            "segmentIndex": 14
          }
        ]
      },

Untuk memilih panel di segmen atap dengan karakteristik tertentu, Anda dapat memfilter berdasarkan segmentIndex. Misalnya, jika Anda ingin menempatkan panel di bagian atap yang menghadap ke selatan, identifikasi segmen atap mana yang memiliki nilai azimuthDegrees antara 90 dan 270, lalu gunakan segmentIndex yang sesuai untuk memfilter daftar panel lengkap untuk segmen atap tersebut.

Meminta data array yang terdeteksi

Solar API mendeteksi instalasi panel surya di atap yang ada menggunakan citra satelit. Untuk mengetahui informasi tentang wilayah yang didukung, lihat peta cakupan .

Untuk meminta data array yang terdeteksi, tetapkan parameter additionalInsights ke DETECTED_ARRAYS di isi permintaan Anda:

curl -X GET "https://solar.googleapis.com/v1/buildingInsights:findClosest?location.latitude=49.9263&location.longitude=11.5870&additionalInsights=DETECTED_ARRAYS&required_quality=BASE&key=YOUR_API_KEY"

Isi respons mencakup informasi tentang apakah instalasi panel surya terdeteksi di atap bangunan (detectionStatus) dan tanggal pengambilan citra array yang terdeteksi, jika tersedia:

{
  "name": "buildings/ChIJ7zV8T9a8oUcRapOpazDCQEE",
  "center": {
    "latitude": 49.9262649,
    "longitude": 11.587273999999999
  },
  "imageryQuality": "HIGH",
  "imageryDate": {
    "year": 2016,
    "month": 6,
    "day": 11
  },
  ...
  "detectedArrays": {
    "detectionStatus": "DETECTION_STATUS_ARRAYS_DETECTED",
    "latestCaptureDate": {
      "year": 2025,
      "month": 5,
      "day": 14
    }
  }
}
