Amortization of a solar installation

The time it takes for a solar installation to pay for itself depends on a variety of factors. Solar installations generally pay for themselves after 9 to 15 years.

With a lifespan of 30 years, your system can even earn you money. If energy prices rise, which will inevitably happen in the future, the system will pay for itself much faster. You will also be less affected by future price increases.

 

You can find the amortisation calculation for your solar installation here. You can use this to calculate the approximate payback period of your solar panels.

To calculate the payback period of your photovoltaic system in years, the purchase and installation costs are divided by the sum of income and depreciation.

 

3-person household, approx. 4 kWp = approx. 25 m2 

• Costs approx. CHF 17,000
• less one-off payment CHF 2,760
• less CHF 3,500 in tax savings at 25 % progression
• less local subsidies, which vary depending on municipality

→ Investment: CHF 10,740.-
Annual electricity output: approx. 4000 kWh

Mit 45 % Eigenverbrauch

(Tagsüber wird der selbstproduzierte Strom selbst verbraucht)

• 55 % des Ertrags wird zu 10 Rp pro kWh ins Netz eingespiesen = 220.- p.a.
• 45 % wird selbst verbraucht → Reduktion der Stromrechnung
  um 470.- (Annahme Energiebezugspreis ist CHF 0.26 pro kWh)

→ Payback 14 Jahre

Die Preise für Solaranlagen sind in den letzten Jahren signifikant gesunken. Aktuell sind die Bedingungen für eine hohe Rentabilität der Solaranlage äusserst vorteilhaft.

Self-produced solar power is significantly cheaper than electricity from the grid:

• Electricity from the power station costs 23 centimes
• Solar power including operating expenses costs 12 centimes

 

Je mehr Sie Ihren selbstproduzierten Strom nutzen, desto rentabler wird Ihre Solaranlage - und desto günstiger fällt Ihre Stromrechnung aus.

 

 

If you do not have an energy storage system, the solar energy can only be self-consumed at the time the electricity is generated. As a result, a considerable amount of the generated energy is not available for self-consumption. This means that instead of using the cheap electricity from your own solar installation, you are forced to purchase expensive electricity from the grid.

How to maximise your own consumption

To avoid this, all you need is a storage solution and a corresponding control system. With the help of an energy storage system, you can increase self-consumption by up to 80 %. Our intelligent smart energy control system increases self-consumption by selectively controlling and switching your appliances off and on. This reduces the need to buy in external electricity.

All information about electricity storage

In many cases, the self-generated electricity cannot be fully used for the home, despite storage solutions and control systems. In this case, the electricity that is not consumed is fed into the grid and sold to the local power station in return for remuneration. This is generally between 4.3 and 15 centimes, depending on the municipality. To find out how much remuneration you can currently receive for solar electricity where you live, please contact the Verband unabhängiger Energieerzeuger (Association of Independent Power Producers) or consult the website of your electricity supplier.

Feeding surplus solar power into the grid

Investing in a photovoltaic system is a worthwhile investment strategy. Let your roof work for you.
