Photovoltaic in Switzerland
Photovoltaic

From Solar Energy to Electric Energy:
Clean, sustainable and free energy.

The two fundamental components of a photovoltaic system are modules and the inverter.
The module (or panel) is made up of photovoltaic cells that convert solar energy into electrical energy, using a principle similar to that of photosynthesis.
The direct current (DC), produced by the module, reaches an inverter and is transformed into alternating current (AC), so that it can be used for domestic/industrial users.
A photovoltaic system must be sized by evaluating electricity consumption and usage habits to maximize self-consumption and buy less energy from the grid.
Excess energy, for example when there is no consumption in the home, can be fed into the grid (counted and paid for according to the annual AET rate) or stored in batteries and reused in the evening hours.

Photovoltaic and heat pump
Photovoltaic and heat pump:
double renewable energy

If you are thinking of a heat pump, combining it with photovoltaic is the right choice!

The photovoltaic system powers your heat pump for free, increasing savings on your bill.

How does a photovoltaic system work at night?
How does a photovoltaic system work at night?

To use photovoltaic systems even at night, you can install a storage system, i.e. batteries that allow you to store the electrical energy produced during the day to use it at night when the system does not produce electricity.
It is also a perfect solution for the operation of your heat pump or for recharging your car!

FAQ
Photovoltaic
The energy produced thanks to the use of the photovoltaic system and not consumed directly by the connected users, can be stored or sold. In the first case, the energy produced is stored with storage solutions and used at any time of the day. In the second case, however, the excess energy produced is sold to your electricity supplier and paid at the market price by the Energy Services Manager. The advantages are therefore very simple.
SET employs professional sheet metal workers and structural engineers who are able to verify and recommend the best structure for the client, proposing concrete solutions to resolve any problems.
No.
Photovoltaic panels transform solar energy into electrical energy with a process similar to photosynthesis. The Solar Thermal system, on the other hand, transforms solar energy into thermal energy, used for the production of domestic hot water or for heating rooms.
SET will take care of the necessary paperwork.
Usually only a simple notification of the installation is necessary, but in some cases a building application is required (new buildings, specific municipal provisions, nucleus).
SET technicians will interface with the municipal technical offices to obtain the correct and fastest authorization.
If well designed and maintained over time (cleaning and periodic checks) on average, a photovoltaic system can produce with excellent yield for about 25 - 30 years. After that, revamping actions can be carried out by replacing only those components (the panels in general) that no longer offer efficient yield levels.
Scheduled maintenance, cleaning and guaranteed material both for duration and for atmospheric agents (hail, strong wind). SET is able to satisfy these needs through maintenance and material contracts with the best guarantees on the market.
The panels can get dirty due to dust, pollen, leaves, sand or other. In the case of panels with a frame, moss can also develop on the lower part over time. Dirt and vegetation cause reductions in yield: professional cleaning of the modules therefore allows you to optimize the performance of the system and extend its useful life.
Only demineralized or rain water should be used for cleaning, since ordinary tap water would leave limescale residues on the system. The use of aggressive detergents is not recommended.
SET provides a professional and economical cleaning service, evaluating the frequency of intervention based on the position of the system and its exposure to deteriorating agents.
The main components of a photovoltaic system are three: Substructure, Photovoltaic Modules and Inverter. The substructure is the mechanical component that allows the fixing and installation of the modules with the best exposure. The photovoltaic module is composed of photovoltaic cells that convert solar energy into electricity (direct current DC). The inverter allows you to connect all the photovoltaic modules together and convert the direct current into alternating current (AC) to be used in our homes or businesses.
Incentives
In order to achieve the objective set by the Energy Strategy 2050, Switzerland will aim – in the coming years – to increase energy production from renewable sources, such as solar, hydroelectric power and geothermal energy.
To date, incentives are provided by the Confederation, the Canton and in some cases by the local Municipality.
They can be combined with each other.
FEDERAL INCENTIVE

Since 2018, the body that deals with incentive programs is the Pronovo AG.

CANTONAL INCENTIVE

The Renewable Energy Fund (FER) finances the construction of plants that produce electricity from renewable sources in Ticino, research projects developed mainly in the electricity sector and municipal activities in the field of energy efficiency and saving.

MUNICIPAL INCENTIVE

Some municipalities in Ticino provide incentives for energy efficiency and renewable energy in buildings. In particular, the remuneration fields concern:

  • Installation of a photovoltaic solar system.
  • Replacing an oil or electric heating system.
  • Boiler in heat pump.
  • Storage battery.
  • Energy redevelopment of an existing building.
TAX RELIEF

The investment in a photovoltaic solar system is tax deductible in almost all cantons.
The savings – net of subsidies – are set at the beginning of the year and correspond to approximately 20% of the investment.

INCENTIVES

The Confederation and the Cantons provide a series of incentives for the installation of photovoltaic panels.
There are free tools that can help you get started:

*the cantonal bonus, where applicable (e.g. Ticino) is subject to different rules

This way you can talk to one of our technicians and find the best solution for your needs.

SET offers its customers a turnkey service, carrying out all the authorization and incentive procedures without hidden costs.

FAQ
Incentives
Currently, for the installation of a photovoltaic system, the confederation presents an important incentive plan, guaranteeing federal incentives in various forms. There are also cantonal and municipal incentives. All these types of incentives are cumulative.
Absolutely not. The practices are included in the SET services and all incentives, once approved, will be registered and collected only and exclusively by the customers, for the entire amount granted.
YES. SET is able to propose partner companies to best protect your investment.
YES. Banks are considering energy efficiency with renewable sources as a financial asset. We can also support you in this respect.
