Increase the revenue of your solar plant, today.
With The Curtailer you take control over your solar production. We automatically shut down before the price goes negative, instead of feeding the grid for nothing. Whatever your business model, we can track it.

Why curtail?
Increasing revenue for your solar assets by:
Export pauses automatically before the price drops deep negative, so a bad price hour never turns your own production into a cost.
Stop feeding the grid the moment it's no longer worth it - production that falls outside SDE++ support or any workable tariff.
How it works
DIY, installer installation, or full service - you choose. Works with 90%+ of inverters (see compatibility list).
We can curtail your installation, or provide control to a grid operator, supplier, or CPO. Alternatively you can manually control your installation from the webapp or integrate our API.
Free in year one. After that, a transparent fee keeps the threshold adjusting automatically as public tariffs and subsidy rules change.
Monitor your profits based on our advanced weather-based solar simulation.
