buildingInsights 端點可提供建築物的位置、尺寸和太陽能發電潛力的洞察資料。我們特別準備 可取得下列項目的相關資訊：
- 太陽能發電潛力，包括太陽能板大小、日照量、碳 偏移係數等等
- 太陽能板位置、方向和發電
- 預估每月最佳太陽能配置與相關費用的預估每月能源費用，以及 優點
如要進一步瞭解 Solar API 如何定義太陽能發電潛力和日照度，請參閱「Solar API 概念」。
API Explorer 可讓您發出即時要求，以便更熟悉 API 和 API 選項：
關於建構洞察要求
如要要求建立深入分析資訊，請將 HTTP GET 要求傳送至：
https://solar.googleapis.com/v1/buildingInsights:findClosest?key=YOUR_API_KEY
加入要求網址參數，指定位置的經緯度座標，以及結果中允許的最低品質等級。
建築物洞察資料要求範例
下方範例會要求取得位於 緯度座標 = 37.4450，經度 = -122.1390：
API 金鑰
如要對回應中的網址提出要求，請在網址後方加上 API 金鑰：
curl -X GET "https://solar.googleapis.com/v1/buildingInsights:findClosest?location.latitude=37.4450 &location.longitude=-122.1390 &requiredQuality=HIGH &key=YOUR_API_KEY"
您也可以將 cURL 要求中的網址貼到瀏覽器的網址列，藉此發出 HTTP 要求。傳送 API 金鑰可讓您享有更完善的使用與分析功能，並進一步控管回應資料的存取權。
OAuth 權杖
注意：這類格式僅適用於測試環境。詳情請參閱「使用 OAuth」。
如要對回應中的網址發出要求，請傳入計費專案名稱和 OAuth 權杖：
curl -H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "X-Goog-User-Project: PROJECT_NUMBER_OR_ID" \
"https://solar.googleapis.com/v1/buildingInsights:findClosest?location.latitude=37.4450&location.longitude=-122.1390"
TypeScript
如要向回應中的網址發出要求，請在要求中加入 API 金鑰或 OAuth 權杖。以下是使用 API 金鑰的範例：
/** * Fetches the building insights information from the Solar API. * https://developers.google.com/maps/documentation/solar/building-insights * * @param {LatLng} location Point of interest as latitude longitude. * @param {string} apiKey Google Cloud API key. * @return {Promise<DataLayersResponse>} Building Insights response. */ export async function findClosestBuilding( location: google.maps.LatLng, apiKey: string, ): Promise<BuildingInsightsResponse> { const args = { 'location.latitude': location.lat().toFixed(5), 'location.longitude': location.lng().toFixed(5), }; console.log('GET buildingInsights\n', args); const params = new URLSearchParams({ ...args, key: apiKey }); // https://developers.google.com/maps/documentation/solar/reference/rest/v1/buildingInsights/findClosest return fetch(`https://solar.googleapis.com/v1/buildingInsights:findClosest?${params}`).then( async (response) => { const content = await response.json(); if (response.status != 200) { console.error('findClosestBuilding\n', content); throw content; } console.log('buildingInsightsResponse', content); return content; }, ); }
資料類型定義
支援的資料類型如下：
