Publisher's description

Polysun is a program that allows to you illustrate the actual state of the existing system in terms of consumption.

This neat application calculates the efficiency of the single components of a solar system, facilitates the selection of the most appropriate components and generates economic viability forecasts and customer reports.

What's new in version 5.8

- Impeccable Polysun reports are provided in a variety of formats (PDF, Word, Power Point, Excel, HTML).
- An ENEV report now provides results in a format that conforms to German standards.
- A new shading editor allows users to account for row-to-row shading as well as shading caused by nearby objects in the easiest possible way.
- The amount of electricity used for self-consumption can now be recorded as an annual value (sum of all counter readings) or as an annual profile.
- Visualization of controller connections: both the location of sensors (in blue) and the controlled element (in red) are displayed.
- The collector model for unglazed absorbers has been expanded so that energy may be also generated if the collector temperature is lower than the ambient temperature.
- The concentrating collector model has been expanded and integrated with a number of collectors. Newly listed items include Solarbeam, a two-axis tracking parabolic collector manufactured by Solartron and NEP PolyTrough 1200, a parabolic trough collector.
