Swiss start-up uses the space between railroad tracks for solar modules
The Swiss start-up Sun-Ways has put a solar system between the train tracks into operation.

In many cases, photovoltaic systems compete for space with other projects. In most cases, however, the space between the railroad tracks remains unused. The Swiss start-up Sun-Ways has set itself the goal of using this space for detachable solar systems. It recently put the first pilot system into operation.

The start-up's website lists the key data of the pilot system installed near the French border. It consists of 48 solar modules, has a maximum total output of 18 kilowatts and extends over 100 meters. The electricity is fed into the public grid. The company expects an annual yield of 16,000 kWh, which is roughly equivalent to the consumption of five three-person households.
Trains clean the solar modules
Sun-ways uses a special rail vehicle which, according to the start-up, can lay up to 300 meters of solar modules in one hour. The problem of module soiling, which leads to a lower energy yield, is to be solved by a cylindrical brush mounted at the end of the trains. The modules can be quickly removed and refitted during maintenance work on the railroad line, for example.

The project will investigate how well rail operations and the solar power plant are compatible. Further pilot plants are planned in France, Spain, Romania, South Korea and other countries.
