[RE-wrenches] Module level MPPT

[frenergy]

Gentlemen and Ladies,

        I'm designing a 4KW res system which has limited roof space and 
would like to use a certain number of panels to satisfy power requirements 
and inverter voltage needs.  However, this would necessitate placing 
2-3-maybe 4 PVs (in one string, of two string total) in a location which 
would recieve shade from the second story from about sunrise until, say 
10:30 PDT.

        I'm not interested in going individual inverters on all PVs, but 
would appreciate feedback on the use of  module level MPPT trackers such as 
Tigo or Solar Magic, or??  only installed on the shade affected PVs?  Or 
must they be installed on all PVs in that string....or both strings??

Thanks in advance,

Bill
