Keep cool with solar heat

Press GFX DefautWinterthur, 14th July, 2016Polysun planning software, from the Swiss software producer Vela Solaris, presents amazing renewable energy systems on the Energy Day organized by swissnex Brazil at the House of Switzerland in Rio de Janeiro on the 8th of August.


Renewable Energy is making headlines. Since the 2015 Paris Climate Conference, the world is aiming for ambitious climate goals. The task may be daunting, but it is certain that renewable energy is crucial if these goals are to be reached.

Photovoltaics, solar thermal and geothermal sources coupled with heat pumps offer a plenitude of options to provide clean, affordable, endless energy for heating and cooling buildings. Better insulation of buildings today often means that heating demand is smaller than what renewable energy sources provide. Additionally, overheating of buildings in summer and successive demands for cooling have become more common.

A new addition to the world of renewable energies is a geothermal storage tank that stores solar thermal energy in the ground in hot summers, and its ground source loop make for affordable cooling energy at the same time. You could call it an underground piggy bank to save solar energy.

A considerable challenge is designing the right renewable energy system. A plethora of components, modules, inverters, strings, tanks etc. is available. All roofs differ in size, orientation and pitch, energy demands are different, as are solar yields. It is even more complicated where more than one technology is involved. Many of these multi-technology solutions are, of course, the innovative and smart solutions of the future.

Polysun offers a glimpse into this future. This software, now available in twelve languages including Portuguese, combines photovoltaics, solar thermal, geothermal and heat pumps in one tool. Ready-to-use templates make designing a system from scratch easy. Constantly updated component data bases on the Cloud let you browse for the parts that best suit your needs. Detailed charts and graphic displays of the system make the software easy to use and the systems designed easy to explain and install. Polysun makes planning or optimizing renewable energy systems efficient, fast and even fun.
