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.
Why this is narrow
The public tools should help without creating support promises.
These pages answer useful energy questions without implying every device stack is supported or estimating savings before we have real installation data.
No broad compatibility claims
Supported-device fit changes as integrations mature, so device-specific checks belong in the signup flow.
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 economics are helpful context without overcommitting the product.
Current free tools
Three practical checks that support the 1app.energy story without creating a moving compatibility matrix.
UK Energy Mix
Check the current UK electricity mix, renewable percentage, and carbon intensity.
Local Solar Forecast
See sunshine, temperature, wind, and a local 4-day outlook for solar homes.
Battery Export Profit
Check whether an export rate clears replacement import cost, reserve, and battery wear.

Need device-specific guidance?
Tell us what is installed at home and we will review fit manually against the current onboarding path.
Start with the signup check.
If your inverter is supported, you can create an account straight away. If it is not listed, the same flow sends you to the compatibility list.
