Free toolsPublic library

Focused tools for solar, battery, and grid context.

We keep the free-tool library deliberately narrow: live grid mix, local solar forecast, and battery export economics. Anything device-specific starts with the signup compatibility check.

About these tools

Free checks you can run before signing up.

They answer useful energy questions. They do not check whether your devices are supported, and they do not estimate your savings.

Device checks happen at sign-up

Choose your inverter at sign-up to see whether your home can create an account.

No generic savings promise

Savings depend on usage, tariff, hardware and behaviour. We use worked examples and live data rather than a broad public estimate.

Still useful before signup

Grid mix, solar forecast and export value are useful context for any UK home.

Current free tools
