e_sunity
Your photovoltaic production, a strategic advantage
What if your company produced part of its own energy?
e_sunity transforms your roof or your site into a strategic asset: fewer expenses, more control, and a strengthened sustainable image from the very first months.
We analyse your needs, size the right installation, commission it and integrate it into your energy ecosystem. Your site becomes more efficient and more autonomous.
With a turnkey solution, clear profitability simulations and the possibility of financing without initial investment, you can move forward quickly… and confidently.
Why install photovoltaics in your company?
Control your energy costs
By producing your own electricity, you directly reduce your dependence on the grid and lower your energy bills. The financial aid available in Luxembourg further enhances the profitability of the investment, with a return on investment generally achieved well before the end of the installation’s lifetime.
Secure your energy supply
Photovoltaics allow you to limit the impact of electricity price volatility and to cover part of your long‑term energy needs. This increased autonomy improves your company’s budget visibility and business continuity.
Embrace the energy transition
Producing renewable energy locally helps reduce your carbon footprint and facilitates your ESG reporting. It sends a positive signal to your clients, partners and employees, aligned with Luxembourg’s energy transition goals.

Personalised simulation: annual production, self‑consumption rate, energy independence and return on investment for an informed decision.
Complete management of procedures: state/municipal subsidy applications and adjustments to your energy contracts.
Advice on complementary and tailored solutions: energy‑management system, energy sharing, charging station and more.
What subsidies are available?
The Luxembourg State supports companies that invest in photovoltaics through energy‑transition and decarbonisation objectives:
1. Klimabonus – investment subsidy
- Covers part of the installation costs.
- Depends on the type of installation and the operating mode (self‑consumption or grid injection).
- Helps significantly reduce the net cost for the company.
2. Calls for tenders for photovoltaic plants
- Investment support for large‑scale or high‑impact energy projects.
- Possibility of remuneration over a defined period based on the electricity produced.
- Some calls include sub‑lots for installations with storage or innovations.
3. Remuneration for renewable electricity production
- Guaranteed feed‑in tariffs for electricity injected into the grid.
- Premiums based on actual production over a defined period.
- Generates additional revenue on top of self‑consumption savings.

These aids can be combined depending on the size and type of project. The exact conditions and amounts evolve annually and must be assessed with the support of an electris advisor.

There is no exact answer, as the amortisation period depends on many factors: system size and orientation, roof configuration, local sunlight conditions, the chosen panels and inverters, and your electricity consumption (the higher it is, the greater the savings).
Using specialised software, electris can simulate your situation by combining your historical consumption data, estimated production according to average sunshine in Luxembourg and your building configuration, in order to precisely assess the financial interest of your project before it begins.
Yes, in most cases it is more advantageous to declare a photovoltaic installation in self‑consumption mode rather than under the guaranteed feed‑in tariff. This allows you to further reduce your electricity bill, limit your exposure to grid fluctuations, and still valorise your surplus electricity.
In Luxembourg, self‑consumption installations benefit from preferential subsidies such as Klimabonus and municipal support, which further strengthens the financial attractiveness of this model.
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 entire life cycle. Checks and interventions are carried out at a frequency adapted to the system’s actual condition and operational needs.
This approach helps preserve performance, reliability and durability, while avoiding unnecessary and costly interventions.
