Swiss Solar Policies

Solar energy has a great deal of possibilities in Switzerland. Free-standing solar farms of all sizes and all types of technologies are being experimented with and look promising.

A solar thermal collector is a device for collecting the energy arriving as sunlight at the Earth's surface. This thermal energy is typically used for heating, cooling, water disinfection, etc. Large-scale installations that collect the solar energy contained in the sunlight are generally referred to as solar power plants.

Solar radiation is energy in the form of electromagnetic radiation from infrared (long) to ultraviolet (short) wavelengths. The amount of solar energy that strikes the earth's surface (solar constant) is about 1,000 watts per square meter under clear skies, depending on the weather, location and orientation.

Solar thermal energy (STE) is the harnessing of the energy in sunlight for generating heat and/or electrical power, and for powering chemical reactions. STE has applications in industry, residential heating and power, and the commercial sector.
