Everything we love: creativity, flexibility, and high quality.
It is a privilege to have such a high-performing manufacturing partner as BIO POWER GROUP.

The Li-Mithra solution combines hybrid photovoltaic-thermal panels with a solar heat pump and a storage system to provide 100% renewable local energy production. Thanks to its patented design, the installation enables smart management of the energy produced, offers a high degree of autonomy, and guarantees high efficiency through the simultaneous use of solar radiation, ground heat, rain, and air.
How does it work?
The system is based on hybrid panels that combine photovoltaic and thermal production with thermal sensors: a heat transfer fluid circulates under the panels and absorbs solar energy as well as heat from the air, rain, and ground. This source feeds an optimized heat pump that provides heat and hot water while regenerating the photovoltaic panel (cooling/better efficiency).
Management is handled by the “Limibox,” which enables smart control, remote monitoring, and automatic optimization based on needs and production.


Simple, cost-effective, and reliable solutions designed for installers who want to save time and enjoy peace of mind.

Turnkey systems for individuals (new builds or renovations) who want to generate their own heating, hot water, and green electricity.

Reliable and affordable energy renovation solutions designed for local authorities on a tight budget

Plug & play energy efficiency for manufacturers who want to reduce costs without slowing down production.
Because energy efficiency should not be a luxury.
We create products and services that make everyday life easier for professionals, improve the profitability of facilities, and guarantee user comfort.
Each solution is designed to adapt to your needs and requirements in the field.
Thanks to Li-Mithra technology, it is possible to hybridize conventional solar panels to maximize their use. The system not only harnesses solar radiation, but also heat from the air, rain, and ground, significantly improving the overall efficiency of the installation.
The system achieves an annual performance factor (APF) of 10 depending on location, which far exceeds that of conventional heat pumps. Every kilowatt produced is used optimally, providing clean, local, and cost-effective energy.
Because the combination of photovoltaic + thermal + heat pump + storage creates a unique synergy for an efficient and sustainable energy transition.
Small power ratings and large custom-designed systems : Li-Mithra adapts to every project, from residential to industrial.
Environmentally friendly: energy-efficient and sustainable design: energy-efficient design, 100% French manufacturing, low carbon footprint, and high recyclability.
Made in France: all components are produced in France within 500 km of the site, ensuring quality, traceability, and support for the local economy.
