Solar panels

Every hour of sunshine counts

SOLSTRÅLE solar system makes it easy to produce clean, renewable energy. Use the sun to power your home and reduce your electricity bills and climate footprint.

Understanding solar systems

1. Collect and convert

Solar modules collect sunlight and use it to produce direct current. The inverter monitors the solar system and converts the direct current into alternating current.

2. Consume or store

If the electricity is consumed directly, for example for lighting, this is called self-consumption. A solar storage unit allows the electricity produced during the day to be stored and consumed in the evening. This increases self-consumption.

3. Share and profit

Surplus electricity can be fed into the grid, for which you are compensated by the electricity company.

Your own solar system is easy to set up in just four steps:

Fact check

General

  • Depending on how much electricity is consumed in the house during the day, in the evening and at night, the self-consumption values (and thus the degree of autonomy) for solar systems without storage vary between 15% and 30%. With a battery storage system, the degree of autonomy can be increased to range from 50% to 90%.

    In order to be 100% independent of the public grid, a greatly oversized generator and storage capacity is required. With normally dimensioned solar systems and storage units, up to over 90% self-sufficiency can be achieved. Complete independence is only worthwhile in rare cases.

    What is desirable above all is a clean energy supply and not self-sufficiency per se. Therefore, a solar system connected to the grid contributes even more to the energy transition than a completely self-sufficient, autonomous solar system.

  • Instead of feeding electricity into the grid, you store your surplus in your battery. In this way, you can use it again in the evening and at night directly from the battery instead of drawing electricity from the grid.

  •  The so-called grey energy is the energy used to manufacture and transport the module. Photovoltaic modules of today's standard already compensate for this grey energy within one to two years, depending on where they are used. This is because they have such a high output and are already energy-efficient in production.

  • Our crystalline photovoltaic modules are 95% recyclable and are made of relatively harmless substances such as silicon, glass or copper.

  • A solar system alone is not enough in the event of a power cut. But with a battery, you are one step ahead of the blackout. It is important that your battery has an emergency power function and is configured accordingly.

  • To be 100% independent of the public grid, you need a greatly oversized generator and storage capacity. Up to over 90% autonomy can be achieved with normally dimensioned solar systems and storage units. Complete independence is only worthwhile in rare cases because it would be oversized for everyday use.

  • Customers in the basic supply (less than 100 MWh electricity consumption/year) are bound to their electricity supplier, which also applies to the return delivery. However, you are free to store the surplus or sell it to your neighbours instead of to the energy supplier, e.g. via a ZEV ("association for self-consumption").

  • The modules do not wear out because they have no moving parts. Nevertheless, they experience a so-called module degradation of approx. 0.5% per year. The manufacturer guarantees that they will not lose more than 0.8% of their output per year and will therefore still have at least 80% of their nominal output after 25 years. You can find more information about this on swissolar.

  • After how many years you will have recovered the investment costs depends on the electricity price, the return tariff and the degree of self-consumption. The marginal tax rate also plays a role, as it determines the tax advantage and thus reduces the investment costs of the system. The higher all these factors are, the faster a solar system pays for itself. In Switzerland, depending on the region, it takes between 6-7 years in the best cases and 14 and 20 years in the worst cases. We would be happy to advise you personally on this.

  • How much profit you make over the years with your investment in a solar system depends on several factors: Electricity price, return tariff and degree of self-consumption and their development. The marginal tax rate and thus the tax advantage from the purchase of the solar system also play a role.

    Depending on the situation, a solar system can make between 50% and 200% profit over 30 years of operation. Whether a battery makes sense depends on the difference between the electricity tariff and the return tariff of your own electricity supplier. We would be happy to advise you personally.

Requirements

  • Photovoltaic modules have a standard size of approx. 100 cm x 160 cm and an output of approx. 325 Wp. Thus, each kWp of power requires about 5 m2 and each kWp produces about 1000 kWh of electricity per year in Switzerland. An average single-family house with 4 inhabitants consumes about 4000 kWh of electricity. This means that just 20 m2 of roof surface is enough to produce the entire electricity demand of the house annually with one's own solar system. With 50 m2 of solar surface, you can already cover the needs of a house including heat pump and electric car.

  • Almost all roofs are suitable for solar systems, as there are different mounting solutions for flat roofs and pitched roofs.

  • The pitch plays a subordinate role. Orientation towards the south is ideal, but solar systems oriented towards the east and west are also worthwhile even in our latitudes.
