In Switzerland, the cost of electricity can weigh heavily on the budgets of households and businesses. Installing photovoltaic panels allows you to produce your own electricity, reducing your dependence on the traditional power grid and fluctuations in energy prices. Thanks to self-consumption, you use the electricity produced directly on site, thereby significantly reducing your electricity bills. Any surplus energy produced can be fed into the grid and paid for, generating additional income. By opting for an energy storage solution with batteries, you can maximise your self-consumption and optimise your savings.

Solar production represents a clean and renewable energy, unlike fossil fuels such as oil, gas or coal. Thanks to photovoltaic panels, you reduce your carbon footprint and actively contribute to the fight against global warming. Switzerland has committed to an ambitious energy transition, and solar energy plays a central role in this strategy. By making this choice, you contribute to a more sustainable and responsible energy future.
In Switzerland, the installation of photovoltaic panels is encouraged by attractive subsidies and financial incentives, at both federal and cantonal level. These financial aids, notably via Pronovo, can cover a significant portion of the investment costs, making your project even more accessible and profitable. In addition, some cantons offer tax breaks for owners who invest in renewable energies.

Installing photovoltaic panels is an investment that enhances the value of your property. A house or building equipped with a solar installation is perceived as more modern, ecological and economical. This increases the market value of your property and makes it more attractive to potential buyers. In a real estate market increasingly sensitive to environmental issues, this installation becomes a major asset.

Photovoltaic panels are reliable and durable equipment, with a lifespan of several decades. Solar technologies have evolved considerably in recent years, offering increasingly high yields and better resistance to the elements. The installation represents a long-term investment that guarantees stable and efficient electricity production for many years.
In Switzerland, the installation of solar panels takes place in several stages. After a feasibility study to determine the optimal location, according to the installation's power (in kWh) and inclination, the solar panels are fixed on the roof or on the ground using suitable supports. There is no need to dismantle the roof: solar panels can be installed as an overlay.
Professionals then carry out the wiring to connect the panels to the inverter. This converts the direct current produced by the panels into alternating current usable in your home. A bidirectional meter measures the electricity produced and consumed.
Finally, your distribution grid operator carries out the connection to the public grid after an inspection of the installation. The entire process, from planning to commissioning, is generally entrusted to certified professional installers. In Switzerland, it is important to comply with safety standards and local regulations to guarantee a compliant and efficient installation.
Installing a storage battery allows you to optimise the energy produced by solar panels through self-consumption. By storing the excess energy produced during the day, you can use it in the evening or on days with low sunshine, thereby reducing your dependence on the grid and maximising your savings.
As the cost of batteries has decreased in recent years, this option is becoming increasingly attractive. However, the initial investment remains high. Installing a battery is particularly worthwhile if you have significant electricity consumption in the evening or if you wish to increase your energy independence. EDIREX can advise you on whether a battery is suitable based on your consumption profile and objectives.
If you decide to install solar panels, you must first submit a building permit application to your municipality. You need to provide documents such as installation plans and the technical specifications of the equipment. It is also important to inform your distribution grid operator of your project and obtain approval for connection to the grid.
In Switzerland, subsidies and financial incentives are available to encourage the installation of solar panels on your roof. We recommend checking with your canton and the Confederation to find out which aids you are entitled to and to submit the relevant applications. EDIREX supports you with these administrative procedures.

For solar installations, profitability depends on several factors, such as the installation's power, sunshine, the cost of electricity, and the subsidies and financial incentives available.
In general, investment in solar panels is profitable in Switzerland thanks to the reduction in electricity bills, the remuneration for surplus energy fed into the grid, and the increased value of the property. The payback period for a solar installation generally ranges between 10 and 15 years, after which it generates profits.
Online simulation tools allow you to estimate the profitability of a project based on its specific characteristics. Feel free to contact EDIREX for a personalised analysis of your situation.
