(PresseBox) ( Chicago, Illinois, )
At AHR Expo, Vela Solaris (, a privately-held corporation providing software solutions for the renewable energy sector, will be demonstrating its latest release including North American manufacture’s hydronic system templates (Booth #3015).

«By including our hydronic templates we aim to help Polysun users to prepare professional proposals for SunEarth systems», says Paul Outram, Manager of SunEarth Inc., «This will allow users to provide high quality proposals quickly».

Polysun makes it possible for manufacturers to make the performance of their components available to installers, planning offices and energy consultants by means of optimized system templates. These enhanced system templates enable Polysun users to generate reliable yield predictions and thus build confidence among building owners and decision-makers in a matter of minutes.

«Working with Polysun facilitates and speeds up our planning process tremendously», says Ole Pilgaard, President and CEO of Helidoyne inc. «Polysun greatly simplifies the system design process and also serves as a sizing instrument. In addition, Polysun generates professional PDF-reports that are a great help in sales and marketing».

The following North American companies have integrated Polysun system templates:

• SunEarth inc. provides more than 20 DHW system diagrams
• Heliodyne inc. provides multiple DHW, Space heating, and pool heating system diagrams
• UMA Solar recently added 4 DHW system diagrams
• Solar Hot USA provides 3 DHW systems including their pump station
• SunMaxx Solar provides DHW, space heating, and pool heating system diagrams
• Northern Lights Solar Solutions, a Canadian system provider, recently launched 13 new system diagrams in Polysun, including DHW, Space heating, pool and cedar tub heating, etc.
• Evosolar Jomar provides 3 DHW systems

«A key part of promoting Solar systems in the US is providing an accurate forecast of system output and financial return for the end user» commented Dan Gretsch, Vice President of Engineering of Solar Hot USA. «Polysun not only delivers this ability but also provides unparalleled tools for system component selection and sizing».

Each Polysun product can be purchased in two different configurations with feature-sets tailored to the needs of different user levels: Polysun Professional and Polysun Designer.

Polysun Professional has become an essential tool for the sales staff and designers of solar residential installations. It is easy to use, includes North American system diagrams of the manufactures mentioned above, a lot of generic templates, and an updated SRCC collector database. How can Polysun help you?

• Time-saving design thanks to ready-made company templates
• Descriptive reports that satisfy customers
• Successful incentive applications
• Build customer confidence through competence

Polysun Designer is a dedicated tool for designers and planners of commercial installations. The program allows the user to arbitrarily combine and simulate hydronic solar plants and calculate solar gains for complex systems.

• Exact drawing and illustration often is a key to convincing a customer
• The exact reproduction of a system leads to very accurate results

«We consistently strive to improve upon our industry-leading Polysun software, and we are thrilled to have added US manufacturer’s data to our Polysun line of products as yet another key benefit of our product over competing offerings in the United States», said Simon Geisshuesler, chief marketing officer of Vela Solaris. «The most accurate and cost effective energy efficiency reading possible is of upmost importance to our customers, and the addition of market available system diagram data only strengthens the Polysun software’s ability to provide the most accurate and efficient solution available».

Polysun products make the design of solar thermal systems simple and professional. The software takes into account data from building geometry and orientation, domestic hot water consumer profiles and a variety of other loads – with a complete year dynamic simulation – providing reliable yield forecasts that generate a much more precise read of what the energy efficiency will be and an accurate return on investment. Additionally, they offer the most comprehensive climatological database, with more than 8,000 weather station data points, making Polysun systems more accurate than any other program available.

«Thanks to the combined development of the customized Polysun Simulation Software, Northern Lights Solar Solutions now offers customized solar simulations built directly around their pre-designed packaged solar hot water heating systems, completing its “Plug’n Save” product range. This software tool will accurately predict the performance of any one of our pre-packaged solar heating systems making it a valuable tool for our dealers and customers» commented Director of Northern Lights Solar Solution Dan Jung.

Polysun software updates are released regularly, every three to four months, and are included in the yearly subscription contained in every purchase of the software for Professional and Designer level. Polysun Professional Solarthermal is $899, and Polysun Designer Solarthermal is $1,949. Solar PV, Geothermal, and Cooling modules can be added at a surplus.
