Case Study: The Solar Calculator by Contigo Energía

Contigo Energía, a branch of the Gesternova Group, has been providing 100% renewable energy and representing clean energy producers since 1986. Specializing in solar photovoltaic energy, they needed to update an essential tool for their users: the solar self-consumption calculator on their website.

To update and improve the existing solar calculator, allowing users to estimate the installation cost of self-consumption solar systems, making it more intuitive, accurate, and accessible.

We began with a series of conversations with the client to better understand which improvements were the top priority. With that information, we planned a comprehensive update that would add new functionalities and optimize the user experience.

We modernized the calculator to now gather key data such as location, roof orientation and tilt, along with the user’s consumption patterns. The tool, powered by an internal service from Contigo Energía, provides personalized budget estimates. Additionally, we integrated the Google Maps API, which allows for address autocomplete, making the entire process more intuitive.

Here’s the process we designed to request a solar self-consumption quote:

In our effort to optimize and transform Gesternova's website, we used a variety of tools and platforms. The main ones included:

The new calculator is not only easier to use, but also improved in design and functionality, leading to an increase in inquiries about solar self-consumption systems. We also cleaned up the code to minimize errors and improved the page’s accessibility and SEO, ensuring smooth navigation and greater online visibility.
