Quickstart

Get your API key

Sign up at pvnode.com and create an API key in your dashboard.

Make your first forecast request

Install the requests library if you don't have it:

Code
pip install requests

Then run this Python script:

forecast.py
import requests

response = requests.get(
    "https://api.pvnode.com/v1/forecast",
    headers={"Authorization": f"Bearer YOUR_API_KEY"},
    params={
        "latitude": 51.0,
        "longitude": 10.0,
        "slope": 30.0,
        "orientation": 180.0,
        "pv_power_kw": 10
    }
)

data = response.json()
print(f"Status: {response.status_code}")
print(f"First entry: {data['values'][0]}")
