Calculating SolarWall® Solar Air Heating System Savings

The RETScreen software, developed by Natural Resources Canada, has become the standard modeling software for calculating cost savings, and it is available below. It simulates numerous renewable energy technologies.  RETScreen v3.1 ( click here to download) uses empirical data obtained from dynamic testing performed by Natural Resources Canada on the performance of SolarWall. This combines with NASA weather data and user input site conditions to provide the most comprehensive assessment of SolarWall energy performance.
