A solar sizing and selection tool in the palm of your hand

Discover the Grundfos GO Solar app and learn how to size and select your solar pumping system. Use the details you have on hand to find the right solution for your application and get free access to helpful tools and calculators.

Simple pump selection that fits your needs with three ways to size

With the Grundfos GO Solar app, you get quick and easy solar pump sizing regardless of your location, internet connection or application needs.

The app includes sizing details for our full range of renewable energy powered products including the SQFlex submersible, CRFlex booster and Renewable Solar Inverter (RSI). The Grundfos GO Solar app also pairs our RSI solution with applicable AC powered pumps to ensure maximum coverage for all solar applications.

Use the Grundfos GO Solar App to size a pump in three different ways...

Size pumps against those you have in stock or those you have with you on the job

Scan the pump's barcode and use the app to determine whether it meets the requirements of your application.

See the pump’s head and flow capabilities and the estimated number of solar panels needed for operation based on the application’s geolocation.

Size by the number of solar panels and always meet application space or budget requirements

Use the app to estimate which pumps are able to meet head and flow requirements based on the power available.


Size by your application requirements and ensure the pump is customised for the job

This feature allows you to base your head and flow on data such as well depth, pumping distance and location. The app will then provide a list of appropriate pump models and an estimate of the number of solar panels needed for the application.
