Energy by the sun

The sun delivers energy whatever the weather conditions. It is safe, clean and free of charge. So a house equipped  with solar panels adds up. So cover your basic energy resources needed by new and old buildings and be independent as well as ecologically advanced in all areas: warm water, electricity and climate.

We distinguish between two major areas:

Photovoltaic – electricity provided by the sun
Solar heat – warm water provided by the sun

Sun powered electricity

Solar cells convert solar radiation into electrical energy – without moving parts, nor noise or emissions. This technology is called photovoltaic and is going to be a major part of global energy supply in the 21st century. Yearly expansion rates of 30 to 50 percent show clear signs of an unstoppable boom. And each year the growth of supply by solar cells is larger than the one by nuclear plants. The photovoltaic line of business already has an important economical activity generating thousands of jobs and a annual sales of about two billion CHF.

Sun powered warm water

You can rely on warmth throughout the whole year. Solar collectors can be combined with different heat generators that are powered up in times of lower solar radiation. For example wood firing, heat pumps, oil or gas fueled boilers. Thermal systems can be used in several ways. To heat domestic hot water, to support the heating installation, within a family home or apartment buildings, for swimming baths and many more!

 

 

Building with the sun

The sun yearly emits around seven thousand times more energy than the worldwide demand for energy. Even in Switzerland a country that doesn’t enjoy much sun, it still offers some remarkable possibilities, here are some interesting facts:

The sun

- radiates with up to 1200 Watts per square meter (in the midlands, even more in higher regions)
- shines over 1000 hours a year
- delivers over 1000 kWh a year per square meter which equates to a heat value of around 100 liters of oil

An average family home uses around 1000 liters of oil for heating per year. If we could capture the sun on a region of 10 square meters, we would be able to produce enough energy to heat the house.

So building with the sun produces localised carbon free energy and promotes improved efficiency by displacing the use of fossil fuels.
