Userfriendly solar shadings simulator.
This app gives a graphical representation of the sun path as well as a chart to see what percent of daily hours are lost per month and a kWh output graph.
The kWh output graph can be configured to use PVWatts data for an accurate kWh output or calculated using only the incident angle of the graph to model monthly dips in production due to array tilt angle. This analysis can be printed to PDF and sent to yourself or a client. Multiple shading analyses can be performed and saved to the user's SDcard.

Price : 16 $US
