ScanTheSun

SCAN THE SUN, Solar collector software

ScanTheSun app calculates best direction and insolation of a solar collector panels

taking into account surrounding trees, buildings or other sources of shading.
ScanTheSun allows to :

- calculate the solar energy reaching the collector

- find the energy loss due to shadow casted by objects in the vicinity

- plan the thermal collectors mounting (selection of the best part of the roof, proper panels orientation) even in a complicated urban areas

- calculate the hours of hot water warming or electric energy production during the day - prepare a complex documentation of insolation and efficiency of solar installations


Get ScanTheSun on in Google Play Store

KALKENER

Kalkener's online solar simulation software allows calculating solar thermal water heating systems:
the sizing of its main components according to the monthly, weekly and daily hot water consumption profiles, the solar site survey, the shading, orientation and tilt losses, the optimal position of solar collectors located on sloped roofs, the annual solar energy production (taking in account losses) and its key profitability indicators, (IRR and NPV).
The aim of this software is to calculate in an accurate, fast and cheap way all the neccesary data in order to make the proper decision on whether or not to invest in this type of facilities.
