This tool, which combines real data, statistical studies and algorithms, allows the performance and profitability of an installation to be simulated as closely as possible. Since its commissioning, MyProSizer has been constantly improved by the MyLight R&D teams and knows a real success with installers: + 400% use between January and March 2021.
The energy transition will go through the professionals
MyLight Systems is deeply convinced that the massification of solar self-consumption will go through professionals. With MyProSizer, MyLight Systems provides them with a turnkey tool to help them offer their customers solar kits perfectly suited to their needs thanks to an energy and financial performance calculation.
MyProSizer facilitates the study of the installer and allows him in a few clicks to:
- Provide a personalized study of the project to his client-
- Study different projects, varying the power of the panels
- Integrate the best technologies, such as bi-facial bibscreens or the virtual battery
Ergonomic and easy to use, MyProSizer allows the installer to gain in efficiency, reliability and productivity, while providing visibility and confidence to the user.
MyProSizer, simulations built on real data
For more than 7 years, MyLight Systems has been monitoring, analyzing and managing thousands of sensors on its self-consumption sites. This real-time data collection enabled the Data Science team to program software simulating hour-by-hour consumption and production profiles, precisely taking into account the different possible devices in a household. It also takes into account the meteorological factors of each location over the last 15 years to be as close as possible to real conditions. Because a summer day is not a winter day and all days are not the same! Green Play optimization algorithms have also been integrated in order to predict as accurately as possible the impact of MyLight Systems management on an installation.
Finally, the latest innovation, MyProSizer also integrates MySmartBattery, the virtual battery in real time.
“To know exactly how profitable a battery is, it is important to predict the excess production stored hour by hour. Without this precision, we cannot calculate the number of cycles made by the battery and therefore its rate of use. " explains Mathieu Bourque, CTO of MyLight Systems

Growth of 400% in the 1st quarter of 2021
Because a good installation begins with an accurate sizing, the installers very quickly adopted the tool which represents a guarantee of reliability in the energy estimate of a home and the assurance of better customer satisfaction. MyProSizer has experienced very strong growth since its launch in 2019. In fact, in 2020, 1 monthly simulations were recorded, or around 000 over the year. In the first quarter of 12, MyLight Systems teams already totaled nearly 000 simulations, i.e. a fourfold increase in the number of simulations.
A trend that is not ready to be reversed since the software evolves regularly to keep up with market developments and new user use cases, such as recharging an electric vehicle, heat pumps and other systems. of heating.
“We started by putting our digital expertise at the service of auto consumers, we are now putting it at the service of installers. Digital is really at the heart of the energy transition! " concludes Ondine Suavet, Managing Director and co-founder of MyLight Systems.
