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。具體來說，您可以取得以下資訊：
- 太陽能發電潛力，包括太陽能板大小、每年日照量、碳抵銷因素等
- 太陽能板的位置、方向和發電量
- 預估最佳太陽能板配置的每月能源帳單，以及相關成本和效益
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」。
您可以透過 API Explorer 提出即時要求，熟悉 API 和 API 選項：
關於建構洞察要求
如要要求建構洞察資料，請傳送 HTTP GET 要求至：
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必要品質等級。
建築物洞察資料要求範例
以下範例會要求建構經緯度為緯度 = 37.4450 和經度 = -122.1390 的資料位置深入分析資訊：
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 金鑰可提供更完善的使用和分析功能，以及更完善的回應資料存取控制功能。
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提出要求，請傳入您的帳單專案名稱和 OAuth 權杖：
curl -H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "X-Goog-User-Project: PROJECT_NUMBER_OR_ID" \
"https://solar.googleapis.com/v1/buildingInsights:findClosest?location.latitude=37.4450&location.longitude=-122.1390"
TypeScript
如要對回應中的網址提出要求，請在要求中加入 API 金鑰或 OAuth 權杖。以下是使用 API 金鑰的範例：
/**
* Fetches the building insights information from the Solar API.
* https://developers.google.com/maps/documentation/solar/building-insights
*
* @param {LatLng} location Point of interest as latitude longitude.
* @param {string} apiKey Google Cloud API key.
* @return {Promise<DataLayersResponse>} Building Insights response.
*/
export async function findClosestBuilding(
location: google.maps.LatLng,
apiKey: string,
): Promise<BuildingInsightsResponse> {
const args = {
'location.latitude': location.lat().toFixed(5),
'location.longitude': location.lng().toFixed(5),
};
console.log('GET buildingInsights\n', args);
const params = new URLSearchParams({ ...args, key: apiKey });
// https://developers.google.com/maps/documentation/solar/reference/rest/v1/buildingInsights/findClosest
return fetch(`https://solar.googleapis.com/v1/buildingInsights:findClosest?${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;
},
);
}
