Why install photovoltaics at home?
Reduce your bills. Increase your home’s value.
Use the electricity you produce: less energy purchased, more savings every day. When production exceeds your needs, surplus electricity can be fed into the grid and valorised. In the long term, a photovoltaic installation becomes a lasting real‑estate asset.
Clean energy today, a more sustainable future tomorrow.
A large share of the electricity consumed in Luxembourg is still imported. By producing your own solar electricity, you reduce CO₂ emissions and actively contribute to the energy transition — without compromising comfort.
Less dependence, more energy freedom.
Producing your own electricity helps protect against price increases and market uncertainty. Combined with a battery, your installation can also provide backup power and strengthen day‑to‑day autonomy.
Energy sharing
With Enovos’ Energy Sharing service, locally produced renewable electricity can be shared between neighbours, residences or municipalities. A simple solution to better valorise solar production and strengthen collective energy autonomy.
Our expertise in numbers:
installations commissioned

Our experts make your life easier
e_sunity offers you many advantages:
Analysis, sizing and planning of your photovoltaic installation and battery storage
Coordination, installation and commissioning handled by our expert technicians
Personalized simulation: annual production, self‑consumption rate, energy independence, return on investment
Complete administrative support: state / municipal subsidy applications and energy‑contract adjustments
The electricity produced and not consumed can be monetised through Enovos injection tariffs. electris advises you in order to optimise your installation and maximise self-consumption.
What subsidies are available?
The Luxembourg State supports homeowners who invest in a photovoltaic installation through the Klimabonus program, which contributes to national decarbonization goals.
To be eligible, the installation must:
- be located in Luxembourg on a residential building (single‑family house or co‑ownership),
- have a capacity of at least 2 kWp and operate in self‑consumption,
- be carried out by an approved installer,
- be a new installation or an extension of an existing installation.
New scheme – with pre-financing:
In most municipalities, local grants are also available.
You can simulate your subsidies on aides.klima-agence.lu
Combine your installation with our Home Energy Management System
Starting at €7/month, e_productivity — the energy conductor of your home:
- connects all your equipment
- maximises self-consumption
- adapts to your habits and lifestyle

There is no exact answer, as the amortisation period depends on many factors: system size and orientation, roof configuration, local sunshine conditions, panel and inverter models, and your electricity consumption (the higher it is, the more savings you will make).
In Luxembourg, considering available subsidies, a typical residential installation is usually amortised in about 4 to 7 years for a single‑family home, far below the expected lifespan of a photovoltaic system.
Using specialised software, electris can simulate your situation by combining your historical consumption data, estimated production based on average sunlight in Luxembourg and your building's configuration, to accurately assess the financial interest of your project before it begins.
Yes, in most cases it is more advantageous to declare the installation in self‑consumption mode rather than under the guaranteed feed‑in tariff. This reduces your electricity bill, limits your exposure to grid fluctuations and still allows you to valorise your surplus by injecting it into the grid.
In Luxembourg, self‑consumption installations benefit from preferential subsidies such as Klimabonus and other municipal aids.
electris supports you in analysing your needs and choosing the most suitable configuration.
Operating costs are low compared to the energy savings generated (annual costs <1% of investment). Although photovoltaic technology is mature and reliable, regular monitoring and appropriate maintenance are recommended to ensure optimal long‑term performance.
Through its preventive and corrective maintenance services, electris ensures the proper functioning of your installation throughout its lifecycle. Checks and interventions are carried out at an appropriate frequency based on the system’s actual condition and operational needs.
This approach preserves performance, reliability and durability while avoiding unnecessary and costly interventions.
