What people say.
The input of technical parameters and shading scenarios with pvnode is much easier than with established software. Our students were very positive.

The best provider out there right now.

I've tested quite a few. pvnode is the most accurate for me, with so many options — snow-covered roofs, shading and more.
GitHub user
I'd used a couple of services and the differences could be noticeable depending on the weather. With pvnode the gap at peak PV was only around 0.5 kW.

Their forecasts really are spot on.

Tried plenty of forecast services — nothing was as accurate as pvnode. Plus you get nice extras like the temperature outlook.

I use the pvnode Forecast API with Home Assistant. The precision is impressive [...] I can keep my battery SOC in the optimal range much longer.
