profitable solar systems

A solar energy system is cost-effective in almost every case. Here is what you need to know.

The short amortisation period of solar installations

The amortisation period can be very manageable: a solar energy system can be amortised in just 5 to 15 years. The amortisation period depends largely on your own consumption. SolarApp automatically calculates your amortisation period.

The topic of storage

From a technical point of view, a storage unit is not necessary because the public grid acts as a storage unit. However, the local storage unit serves to increase the solar coverage ratio and can thus increase economic efficiency, because the basic principle applies: the more of your own electricity you can use, the more economical it is. Whether a storage unit is right for you depends on two questions:

What is my consumption behaviour?
How important is energy independence to me?

You can decide on a storage tank even after the solar heating system has been installed, as the storage tank can easily be retrofitted.

The importance of captive use

Self-consumption is the electricity you produce and use yourself. The electricity that you do not consume yourself and feed into the grid is the surplus. You pay more for the electricity you purchase from the energy supplier than you are paid for the surplus. That’s why your solar installation is particularly economical if you use your own solar power directly in your home.

‘ZEV’ – briefly explained

Several parties can purchase electricity from the same solar installation, further increasing the economic viability. This group of self-consumers acts as a single electricity purchaser vis-à-vis the energy supplier. Automatic billing systems ensure uncomplicated billing within the group.

Heat your home and hot water with the PV system

In combination with a heat pump, a photovoltaic system is one of the most efficient and environmentally friendly heating systems available. The investment also pays off financially. In addition, a PV system and a heat pump boiler can also be used to heat water very efficiently.

What affects the price and return on a solar energy system

The prices for solar energy systems depend on the system selected (rooftop, roof integrated, facade) and the specific roof situation (simple rectangular roof or complicated angled roof). A large part of the work is taken up by planning and coordination. SolarApp streamlines the planning process and reduces the administrative effort, thus saving considerable costs. In addition to the orientation of the system and the investment costs, the return depends above all on your own consumption. The return can be up to 15%.

Financial support for solar installations

New solar energy systems are subsidised throughout Switzerland today according to the single tariff model. Every newly constructed system receives a basic amount and a further performance-related subsidy. SolarApp calculates exactly how much funding you are entitled to for your system and whether you can claim a tax deduction on top of that.

Saving with the BIPV substitution effect

Building-integrated solar energy systems are also referred to as Building Integrated PhotoVoltaics (BIPV). BIPV solar modules have another advantage besides the production of electricity: they can replace roof tiles, serve as facade cladding or be used as balcony railings. These solar building elements save material and, accordingly, costs.
