Daily Modelling

This utility allows you to model the daily performance of your solar and battery installation. It is useful to plan what kind of solar and battery installation to invest in, and also to check if your current installation is performing as expected. You can also see the effect that a change of smart tariff might have.

Solar Forecast

This utility will show you the level of solar generation you can expect to receive for your particular solar installation over the next 7 days. It uses data from Forecast Solar which may or may not be relaible.

Battery Only

This utility is for those who would like to consider a battery-only installation (i.e. without solar panels). Upon entering pertinent information, it will calculate a payback period for such an investment.

Agile Rates

This utility is for those in the UK who are on the Octopus Agile Tariff. It will show today's prices, and also tomorrow's prices if they are available (typically after 4pm on the day).

Investment

This utility is for those who want to see which is a better investment financially - solar panels or a financial investment?
