GetSolar OverviewSizing Options2 Components:• Wizard• Streamlined process for quickly sizing an application withminimal details and at default system settings• System Parameters (detailed system setup)• More comprehensive methodology with ability to add andchange the various parameters of the system giving a moreaccurate system design3TT/SNA-MKT3 | 9/16/2010 | © 2010 Robert Bosch LLC and affiliates. All rights reserved.

GetSolar OverviewMethodology for Using GetSolarBest method:• Step 1: Use the wizard to get an initial estimate for the number ofcollectors, total storage, and solar fraction• Step 2: Go through the system parameters menus and make changeswhere applicable• Step 3: Simulate the system and analyze the results• Step 4: If necessary, go back and optimize the system by altering thevarious parameters including number of collectors, tank volume, andsystem typeRules of thumb:• 1.5 gallons of storage per 1 sqft of collector surface area for DHW• 2 gallons of storage per 1 sqft of collector surface area for DHW + SpaceHeating• Set the collector angle near the latitude angle of the project location forDHW only and add 15 degrees to the latitude for Space Heating4TT/SNA-MKT3 | 9/16/2010 | © 2010 Robert Bosch LLC and affiliates.
