Product design

Real-time solar design

Once a solar panel is added, the ROI, with real-time calculations, is instantly visible. Installers can design in front of the customer, making it a powerful sales tool as well.

The only solar configurator

Once the system is designed, installers send out a configurable quote giving solar customers the power to configure their solar system (leveraging the IKEA effect).

Add-ons to increase basket value

To increase basket value, we designed the add-on flow that made it super simple for customers to add and customise their needs without feeling overwhelmed.

Real time calculations on customer choices

To keep users feeling in control during the decision phase, we provided easy-to-understand data to help users choose the right equipment upgrades in a single click.

A tool to unite on-site teams

Once the solar system design is confirmed by the customer, the on-site installers have an easy to access app to link up with the entire process seamlessly.

Increasing installer team efficiency

To increase team efficiency, a simple dashboard surfaces only the to-do items and events for that user.

Top level view for resource management

A quick drag-and-drop team management tool makes managing resource at a team level powerful and super simple.

A powerful sales dashboard

Giving solar company owners the power to track sales and performance data, simply.

Instant quote lead gen tool

Solar installers can embed our brandable instant quote tool and start seeing leads pour into the CRM.

Helping solar installers deliver great UX

From instant quoting, solar design, to customer portal and CRM, we give even small solar companies the power to deliver beautiful, highly efficient experiences.

White labelling impact with global brands

The lead-gen tool we designed was tested and used by the likes of EDF, Scottish Power, and Duracell. Put up against other implementations ours outperformed with 2x conversions. Backed by this data we offered it to installers all over the UK.

Team Fuze

Using the IKEA effect to help nudge sales

The hypothesis is people desire configurators instead of static quotes. This is used in most industries because of an established cognitive bias called the IKEA effect where people place higher values on things they've built.

In this first iteration we hint at it with choices of panels and battery. More recently we've pushed this even harder, allowing solar brands to customise over 400 elements of their system.

Dynamic, configurable quote

A/B Testing

We also designed up A/B tests to measure optimal flow lengths

This same flow was white-labelled, tested and used by multiple energy companies including EDF.
