The sun provides roughly the same amount of energy every day as the entire world needs in eight years.

In contrast to fossil fuels, whose resources are limited, the sun is available to us every day as a free source of energy. Energy generation is always emission-free, noise-free and odorless. Not only does the environmental protection concept play an important role, but the economic component also ensures a high return on investment thanks to the good price-performance ratio.

The extremely low-maintenance and safe solar technology has a very long service life and makes its operators independent of energy providers and fluctuating electricity prices.

By the way: the energy required to manufacture the components is amortized after just a few years of operation of your photovoltaic system.

Two companies, two countries, one ideal offer:
Alka Solarsysteme from Kriessern and the Vorarlberg photovoltaic market leader Hansesun combine their strengths to form Hansesun Photovoltaik Swiss GmbH.

We now offer everything to do with photovoltaic systems and electricity storage:
consultation and planning, the processing of subsidies and the complete installation of the system.

We are convinced:
Photovoltaics are worth it, for our environment and for your wallet.

Because: The sun doesn't send a bill.

We look forward to your enquiry!
