I don't believe you can model a solar thermal collector in eQuest.
What I usually do is model the standard system in eQuest and get an hourly load profile. Then import that load profile into TRNSYS. The caveat with this is that you need to make sure the TRNSYS model doesn't affect the eQuest file improperly by overheating for example.
The alternative would be to create another boiler with a schedule that produces the anticipated amount of heat that the solar thermal collector would produce. You would still need something to inform that schedule, and I'm not sure if this would be accepted by LEED or equivalent.
